Twilio SendGrid
The default transactional email API, plus a marketing product nobody buys it for
Twilio SendGrid is an email delivery platform sold as two separate products with two separate price lists: an Email API billed on monthly send volume for transactional mail such as receipts, password resets, and notifications, and Marketing Campaigns billed on contact count for newsletters and basic automation; it is the highest-volume email sender on the internet, owned by Twilio since 2019, and most buyers choose it for the API rather than the marketing half.
Overview
SendGrid started in 2009 in the TechStars accelerator solving a problem that was unglamorous and universal: developers kept trying to send application email from their own servers and kept ending up in spam folders. It became the default answer, went public in 2017, and was acquired by Twilio in 2019 in an all-stock deal valued around $3 billion. It now moves an enormous share of the world's application-generated email, which is both its strongest argument and the root of its most persistent complaint.
The product is really two products. The Email API is the transactional half: an HTTP API and SMTP relay, official libraries for the main languages, event webhooks, inbound parse, template management, click and open tracking, and a suppression system. It is billed on emails sent, starting at $19.95 a month on Essentials and $89.95 on Pro, with a 60-day free trial capped at 100 emails a day. Marketing Campaigns is the newsletter half: a drag-and-drop designer, segmentation, sign-up forms, single-send campaigns, and simple automations, billed on contact count from $15 a month on Basic and $60 on Advanced, with a permanent free tier at 2,000 contacts and 6,000 emails a month.
The honest read is that SendGrid is bought for the API and tolerated for everything else. Its Marketing Campaigns product is thinner than Mailchimp, MailerLite, or Brevo at comparable prices, with weaker automation and a less pleasant editor. Meanwhile the API half, which used to be the obvious default, has been steadily losing developer affection to Resend and Postmark over console speed, log retention, and support responsiveness, since meaningful support is gated behind higher tiers where competitors include it on every plan.
What it still has is scale, breadth, and the ability to be one vendor for transactional email, marketing email, email address validation, and, through Twilio, SMS and voice. For a small business that already runs Twilio for messaging, that consolidation is a real argument. For a small business that just wants transactional email to arrive and to be debuggable, there are now better options at similar money.
Best for
Development teams that need high-volume transactional sending with mature tooling and are comfortable at scale, and businesses already running Twilio for SMS or voice that want email consolidated with the same vendor and billing relationship.
Not the right fit for
- Small businesses buying an email marketing platform; Marketing Campaigns is materially weaker than Mailchimp, MailerLite, Brevo, or GetResponse at the same money and you will outgrow it fast.
- Teams who want fast, included support when transactional email breaks; support quality is tiered by plan and the entry tiers are widely complained about, where Postmark and Resend include real support on every plan.
- Cold outreach and purchased-list senders; SendGrid's terms prohibit unsolicited email and accounts are suspended, often abruptly and often without a warning email you will actually see.
- Buyers who want one predictable bill; two separate meters, metered email validation, dedicated IP charges, and Twilio's billing model mean the true cost is rarely the headline plan price.
- Anyone whose main criterion is the debugging experience; the console is slower and the activity feed thinner than the newer competitors, which is the single most common reason teams migrate away.
How it works
- 1
You create an account and authenticate a sending domain by adding the CNAME records SendGrid generates, which sets up DKIM and a branded return path. Domain authentication is not optional in practice; unauthenticated sending from SendGrid's shared pools delivers poorly.
- 2
For transactional mail, your application calls the v3 mail send endpoint or relays through SMTP. Official libraries exist for Node.js, Python, PHP, Ruby, Java, C#, and Go. Dynamic templates live in SendGrid with Handlebars substitution, so the payload is a template ID plus data rather than rendered HTML.
- 3
Delivery events come back through the Event Webhook, covering processed, delivered, deferred, bounced, dropped, spam report, open, click, and unsubscribe. SendGrid also maintains suppression groups so recipients can opt out of one category of mail without being suppressed globally.
- 4
For marketing, you import contacts, build segments with SendGrid's query conditions, design a single send in the drag-and-drop editor or with the code editor, and schedule it. Automations exist but are simple sequences with basic branching rather than the deep behavioural flows in a dedicated marketing platform.
- 5
Deliverability tooling is bought separately in effect: Email Address Validation is metered, dedicated IPs come with Pro and Advanced, and Expert Insights or deliverability consulting sits at the top of the price list. On lower plans you are largely on your own with the reputation you build.
Feature breakdown
23 features in 4 modulesEmail API
The transactional half and the actual reason most customers are here.- v3 mail send API
- A mature REST endpoint supporting personalizations, multiple recipients per call, attachments, custom headers, scheduling, and per-message categories for reporting.
- SMTP relay
- Standard SMTP credentials so any framework mailer, CMS, or legacy application can send through SendGrid without touching an HTTP client.
- Official libraries
- Maintained SDKs for Node.js, Python, PHP, Ruby, Java, C#, and Go, plus community libraries for most other stacks.
- Dynamic templates
- Handlebars-based templates stored in SendGrid with versioning, so copy changes ship without a deploy and the API payload is a template ID plus a data object.
- Event Webhook
- Posts processed, delivered, deferred, bounced, dropped, spam report, open, click, and unsubscribe events to your endpoint with signed verification available.
- Inbound Parse
- Point an MX record at SendGrid and incoming mail is parsed into a multipart POST to your application, including attachments, for reply-by-email features.
- Scheduled and batched sends
- Schedule messages up to 72 hours ahead and group them under a batch ID so a whole batch can be cancelled before it goes out.
Marketing Campaigns
Present, competent, and outclassed by the dedicated marketing platforms.- Drag-and-drop design editor
- Visual campaign builder with a parallel code editor for teams that would rather write the HTML themselves.
- Single sends and scheduled campaigns
- One-off newsletters and announcements to a list or segment, with scheduling and basic A/B testing on paid tiers.
- Contact segmentation
- Segments built from contact fields, engagement, and custom attributes, refreshed automatically; capable but noticeably less expressive than a dedicated marketing platform's builder.
- Automations
- Welcome series and simple triggered sequences on the Advanced tier. This is sequence automation with light branching, not the behavioural flow builder you get from ActiveCampaign or Klaviyo.
- Sign-up forms
- Embeddable forms that write directly into contact lists, with double opt-in available.
- Unsubscribe and preference groups
- Suppression groups let recipients opt out of a category rather than all mail, and the same suppression machinery serves both the marketing and transactional products.
Deliverability tooling
Mostly sold as upgrades rather than included.- Domain authentication
- Guided CNAME setup for DKIM and a branded return path, with verification status in the console. Effectively mandatory for acceptable delivery.
- Dedicated IPs
- Included with Pro on the Email API and Advanced on Marketing Campaigns, with IP warmup tooling; not available on Essentials or Basic.
- Email Address Validation
- A metered API that scores addresses before you send to them, sold separately from the sending plans and useful for cleaning imported lists.
- Suppression management
- Automatic global suppression of hard bounces, spam reports, and unsubscribes, all readable and writable through the API.
- Deliverability Insights and expert services
- Reputation reporting and, at the top of the price list, human deliverability consulting. On the entry plans you have neither, which is the main gap versus Postmark's included vetting.
Reporting and administration
Broad, and generally the part people complain about.- Activity feed
- Searchable recent message activity by recipient and event, with retention that is short on lower plans and extendable as a paid add-on rather than being generous by default.
- Statistics and category reporting
- Aggregate delivery, bounce, open, and click statistics sliceable by category, subuser, or IP over time.
- Subusers and teammates
- Subuser accounts isolate sending for different applications or customers with their own IPs and statistics, with role-based teammate permissions above them.
- Single sign-on
- SAML SSO available on higher tiers, along with two-factor authentication and IP access management on the account.
- Twilio account consolidation
- Email sits alongside SMS, voice, and WhatsApp in one Twilio billing and console relationship, which is the strongest structural argument for choosing SendGrid.
Use cases
4 documentedHigh-volume marketplace sending millions of notifications
Order confirmations, dispatch alerts, and messaging notifications run to several million emails a month and cost per message genuinely matters.
The Email API's Pro tier absorbs the volume with a dedicated IP, subusers isolate each product line's reputation, and the per-message cost sits well below the premium developer-focused providers.
Business already running Twilio for SMS
Two-factor codes go out by SMS through Twilio and email is currently on a separate vendor with a separate invoice and a separate compliance review.
Consolidating email into the same Twilio account collapses two vendor relationships into one, with shared billing, shared SSO, and a single procurement conversation.
Product team that needs reply-by-email
Users should be able to answer a notification and have it land back in the application as a message.
Inbound Parse takes an MX record and posts incoming mail to the application as a multipart request, which covers the case without adding a second vendor for inbound.
SaaS company running a modest newsletter alongside product email
Five thousand subscribers get a monthly product update and the team would rather not add a marketing platform for one send a month.
Marketing Campaigns Basic handles it in the same account with shared suppression, which is genuinely convenient, though anyone whose newsletter becomes a real channel will move to a dedicated platform within a year.
Pricing
from $15 a month (Marketing Campaigns Basic) or $19.95 a month (Email API Essentials)Two products with two separate meters. The Email API is billed on monthly emails sent. Marketing Campaigns is billed on contact count with a monthly send allowance. Email Address Validation is metered separately again.
| Plan | Price | Includes |
|---|---|---|
| Email API Free Trial | $0 for 60 days |
Unlike Postmark and Resend, this is a trial rather than a permanent free tier, so long-running side projects need a paid plan. |
| Email API Essentials | From $19.95 per month, scaling with send volume |
The entry production plan. The absence of a dedicated IP and the thin support are the two things buyers notice. |
| Email API Pro | From $89.95 per month, scaling with send volume |
Where SendGrid becomes genuinely competitive on unit economics, and where support starts to resemble what competitors include for free. |
| Email API Premier | Custom quoted |
|
| Marketing Campaigns Free | $0 per month |
|
| Marketing Campaigns Basic | From $15 per month, scaling with contact count |
|
| Marketing Campaigns Advanced | From $60 per month, scaling with contact count |
|
Add-ons
- Email Address Validation (Metered per validation): Sold separately from sending; useful before importing a list you did not build.
- Additional dedicated IPs (Charged per IP per month): Included IPs come with Pro and Advanced; extras are billed.
- Extended activity retention (Paid add-on): Default activity retention is short; longer windows cost extra.
Billing notes
- The two products are billed independently. Running transactional email and a newsletter in one SendGrid account still produces two subscriptions, not one bundled price.
- Marketing Campaigns is contact-metered, so the classic hidden cost applies: contacts sitting in your account count toward the tier whether or not you mail them. Unsubscribed contacts should be deleted rather than left in place if you want the bill to reflect reality, and SendGrid does not do that housekeeping for you.
- The Email API is volume-metered, so dormant users cost nothing there. This is why many businesses end up with the API for product mail and a different vendor for marketing.
- Exceeding a plan's monthly email allowance results in being billed for the excess rather than being throttled, so a traffic spike shows up as a larger invoice rather than a delivery failure.
- Annual billing is discounted, with published savings around 25 percent versus paying monthly.
- Support quality is a paid feature. Ticket-only support on the entry tiers is the most common complaint in reviews, and it is the specific thing Postmark and Resend include at every level.
- Activity log retention on lower plans is short by default and extending it is a paid add-on, which matters when you need to prove a message was delivered weeks later.
Value assessment: Modelled at the volumes this directory uses, SendGrid's two meters give very different answers. On the transactional side, a product with 1,000 users receiving three emails each sends 3,000 a month and fits the free trial, then costs about $20 on Essentials once the trial ends. Ten thousand users at three emails each is 30,000 sends, still inside Essentials at around $20 to $35 depending on the volume step. Fifty thousand users at three emails each is 150,000 sends, which crosses into the higher Essentials steps or Pro, landing somewhere between roughly $35 and $90. On the marketing side, 1,000 contacts sits inside the free tier, 10,000 contacts is comfortably inside Basic near its $15 entry, and 50,000 contacts is a mid-band Basic price, still typically under what Mailchimp charges for the same list. The raw unit economics are good. What you do not get at those prices is the debugging experience, the retention, or the support that the premium providers include, and that is the trade SendGrid asks you to make.
Strengths & limitations
Strengths
- Enormous operational scale and a fifteen-year track record, so the infrastructure itself is not the thing that will fail you.
- Competitive unit economics at high volume, particularly on the Pro tier where a dedicated IP is included.
- One vendor for transactional email, marketing email, address validation, and, through Twilio, SMS, voice, and WhatsApp, which is a real consolidation argument for a small business already on Twilio.
- Inbound Parse means reply-by-email features do not require a second vendor, which Resend cannot say.
- Subusers and per-IP reputation isolation are genuinely useful for multi-tenant products and multi-brand businesses.
- Dynamic templates with versioning let non-engineers change transactional copy without a deploy.
- Universal ecosystem support: every framework, PaaS, and integration platform has a SendGrid path already built.
- A permanent free marketing tier at 2,000 contacts is more generous than most transactional-first providers offer on the marketing side.
Limitations
- Support is tiered by plan and the entry tiers are the most consistent complaint in the product's reviews, in a category where the whole point is that someone answers when mail stops arriving.
- The console and activity feed are slower and thinner than Resend's or Postmark's, and short default retention with paid extensions makes historical debugging awkward.
- Marketing Campaigns is a weaker marketing product than the dedicated platforms at the same price, with light automation and a less capable segment builder.
- Account suspensions for policy violations are known to be abrupt, and getting a suspended account reinstated is slow, which is a real operational risk for a business whose password resets depend on it.
- Two separate meters plus metered validation plus IP charges make the true monthly cost hard to predict from the headline plan price.
- Contact-metered marketing billing means unmailed and unsubscribed contacts keep counting unless you actively delete them.
- Being inside Twilio has meant less product attention on the developer experience precisely as newer competitors made that their entire pitch.
Head-to-head comparisons
5 alternativesTwilio SendGrid vs Resend
from $0 for 3,000 emails a month, then $20 a month for 50,000 emailsResend is what a lot of teams leave SendGrid for. It has a faster console, thirteen first-party SDKs, React Email, better logs, and support that answers on every plan, at broadly comparable money below a million messages a month. SendGrid has inbound parsing, which Resend lacks entirely, far better unit economics at very high volume, a marketing product in the same account, and Twilio behind it. Choose SendGrid for scale and consolidation, Resend for the integration and debugging experience.
Full Twilio SendGrid vs Resend comparisonTwilio SendGrid vs Postmark
from $15 a month for 10,000 emails (Basic)Postmark costs more per message and does less, and buys you better shared-IP deliverability, full message content retained up to 365 days, and support included at every tier. SendGrid is cheaper at volume and offers marketing campaigns and address validation alongside the API. If a failed transactional email is a business incident, Postmark is the safer purchase; if you are sending millions of messages and can absorb the occasional debugging inconvenience, SendGrid's economics win.
Full Twilio SendGrid vs Postmark comparisonTwilio SendGrid vs Mailgun
from $15 a month for 10,000 emails (Basic)The two closest competitors in the mass-market transactional API space, both now owned by large parents (Twilio and Sinch respectively). Mailgun's entry plans are cheaper at $15 for 10,000 emails, it has stronger inbound routing rules, and its email validation is well regarded. SendGrid has better marketing tooling, a longer track record, and the Twilio consolidation story. Both suffer the same criticism: heavy consoles and support that costs extra. Pick on which parent company you would rather be billed by.
Full Twilio SendGrid vs Mailgun comparisonTwilio SendGrid vs Amazon SES
from $0.10 per 1,000 emails a la carteSES is roughly an order of magnitude cheaper at $0.10 per 1,000 emails a la carte, and many teams that outgrow SendGrid's bill move there. What SES makes you give up is templates, a searchable activity feed, marketing tooling, and any human support relationship, plus you inherit strict reputation policing where a complaint rate above 0.01 percent pauses your account. SendGrid is the middle ground: more expensive than raw infrastructure, more forgiving, and far quicker to integrate.
Full Twilio SendGrid vs Amazon SES comparisonTwilio SendGrid vs Mailchimp
from $0 (free up to 250 contacts), then about $13/mo on Essentials at 500 contactsNot really the same purchase, but buyers do compare them because SendGrid sells Marketing Campaigns. Mailchimp is a far better marketing platform: better editor, real customer journeys, ecommerce integration, and a large template and integration ecosystem, at a higher contact-based price. SendGrid's marketing half is a convenience feature attached to a sending API. If newsletters and automations are the job, buy Mailchimp; if application email is the job, buy SendGrid and keep marketing elsewhere.
Full Twilio SendGrid vs Mailchimp comparisonImplementation & onboarding
- Setup time
- A day for the Email API in most stacks: authenticate the domain with CNAME records, drop in the SDK or SMTP credentials, and point the Event Webhook at your service. Marketing Campaigns takes longer because contact import and segment design are manual work.
- Learning curve
- Moderate. The API itself is straightforward, but the surrounding concepts pile up: subusers, IP pools, suppression groups, unsubscribe groups, categories, and the difference between the two products' contact models. New users routinely misconfigure suppression groups and wonder why mail is silently dropped.
- Onboarding
- Self-serve on every published tier, including Pro. There is a sales motion for Premier and for deliverability services, but nothing stops a small business signing up and sending the same afternoon.
- Migration notes
- Migrating in is easy and migrating out is easy, which is a compliment to the category rather than to SendGrid specifically. The parts that need care are the suppression list, which you should export and import so you do not re-mail known bounces, and the domain authentication records, which should be added for the new provider before you remove the old ones. On the marketing side, exported contacts import cleanly but automations and segments do not migrate and have to be rebuilt. Expect IP reputation to reset, so ramp volume over a week or two rather than cutting over in one go.

Frequently asked questions
10 questionsWhat is Twilio SendGrid?
SendGrid is an email delivery platform sold as two separate products. The Email API is a transactional sending service billed on emails sent, used for receipts, password resets, and application notifications. Marketing Campaigns is a newsletter and basic automation product billed on contact count. It has operated since 2009 and has been owned by Twilio since 2019.
How much does SendGrid cost?
The Email API has a 60-day free trial at 100 emails a day, then Essentials from $19.95 a month and Pro from $89.95 a month, with both scaling by send volume and Pro including a dedicated IP. Marketing Campaigns has a permanent free tier at 2,000 contacts and 6,000 emails a month, then Basic from $15 a month and Advanced from $60 a month, both scaling by contact count. Annual billing is discounted around 25 percent.
Is SendGrid good for email marketing?
It is adequate rather than good. Marketing Campaigns has a drag-and-drop editor, segmentation, sign-up forms, and simple automations on the Advanced tier, but the automation is sequence-shaped rather than a real behavioural flow builder, and the segment editor is less expressive than dedicated platforms. At comparable prices Mailchimp, MailerLite, Brevo, and GetResponse all give you more. Most people buy SendGrid for the API and keep marketing elsewhere.
Do unsubscribed contacts count toward my SendGrid bill?
On Marketing Campaigns, yes in effect, because that product is billed on the number of contacts stored in your account. Contacts you no longer mail keep occupying a tier until you delete them, and SendGrid does not prune them for you. On the Email API side the question does not arise, because that half is billed on emails sent rather than contacts stored, so dormant users are free.
What happens if I exceed my SendGrid plan limit?
On paid plans you are billed for the excess rather than throttled, so a spike in traffic produces a larger invoice rather than undelivered password resets. The free trial and the free marketing tier do enforce hard caps. This is the safer behaviour for transactional mail but it means there is no ceiling on the bill without your own monitoring.
Can I send cold outreach through SendGrid?
No. SendGrid's terms prohibit unsolicited email and purchased lists, and enforcement is aggressive: accounts get suspended rather than warned, and reinstatement is slow. Because the same account may also carry your transactional traffic, a marketing policy violation can take down your password resets too. Cold prospecting belongs on a dedicated outreach platform with its own domains and inboxes.
Do I need a dedicated IP with SendGrid?
Only at meaningful volume. Dedicated IPs are included with Email API Pro and Marketing Campaigns Advanced, and SendGrid provides warmup tooling for them. Below roughly a few thousand emails a day a dedicated IP has too little traffic to establish a reputation and will usually deliver worse than the shared pool. On the Essentials and Basic tiers the option is not offered at all.
How long does SendGrid keep my email activity logs?
Not long by default, and extending retention is a paid add-on rather than an included feature. This is one of the more common practical frustrations with the product, and it compares poorly with Postmark's 45-day default configurable to 365 days. If you need durable evidence of delivery, capture the Event Webhook payloads into your own storage rather than relying on SendGrid's console.
Does SendGrid support inbound email?
Yes. Inbound Parse takes an MX record for a domain or subdomain you control, parses incoming mail including attachments, and posts it to your application as a multipart request. This is a genuine advantage over Resend, which does not receive mail at all, and it puts SendGrid on par with Postmark and Mailgun for reply-by-email features.
Should I choose SendGrid or Amazon SES?
SES is roughly ten times cheaper per email and gives you almost nothing else: no templates worth the name, no searchable activity feed, no marketing tooling, and no support relationship, plus strict reputation policing that pauses your account if complaints exceed 0.01 percent. SendGrid is the middle ground between raw infrastructure and a premium provider. Below a million messages a month the price difference is usually smaller than the engineering time SES demands.
Editorial verdict
SendGrid is still the safe institutional answer for transactional email at scale, and if you are already a Twilio customer the consolidation argument is genuinely strong: one vendor for email, SMS, voice, and validation, with unit economics that improve as volume grows. But it has lost the thing it used to win on. The console is slow, default log retention is short and costs extra to extend, support is a paid feature in a category where failure means your users cannot log in, and account suspensions arrive abruptly. Resend and Postmark now beat it on every dimension except price at very high volume and the presence of inbound parsing. On the marketing side the verdict is simpler: Marketing Campaigns is a convenience attached to an API, not a competitive marketing platform, and a small business shopping for newsletters and automation should buy Mailchimp, MailerLite, Brevo, or GetResponse instead. Buy SendGrid for the API when volume is high or Twilio is already in the stack. Do not buy it because it is the name you recognise.
