The transactional email API developers actually enjoy using
Resend is a developer-first email API for transactional mail, meaning receipts, password resets, magic links, and product notifications sent one at a time from your application code, priced per email sent rather than per contact stored; it ships official SDKs for thirteen languages and frameworks, maintains the React Email component library, and has since added a lightweight Broadcasts feature for newsletters, though it is not a marketing automation platform.
Overview
Resend was founded in 2022 by Zeno Rocha and Jonni Lundy on a simple observation: the incumbent transactional email APIs were built in the early 2010s, had been absorbed into telecom conglomerates, and had stopped caring about the experience of the engineer integrating them. Resend's answer was to treat developer experience as the product. The API is small, the dashboard is fast, the docs are readable, and the company open-sourced React Email, a component library for writing HTML email as React components, which became popular enough to pull developers toward Resend on its own.
The core job is transactional. Your application calls an endpoint, one email goes to one person, and Resend handles the delivery, the DKIM and SPF setup, the bounce and complaint webhooks, and the logging. This is a different purchase from a marketing platform. Resend has no automation builder, no lifecycle flows, no behavioral segmentation, no CRM, and no landing pages. It has since added Broadcasts, a no-code editor with audiences, contacts, topics, and unsubscribe management, which covers a changelog or an investor update but is not a substitute for Mailchimp, ActiveCampaign, or Klaviyo if campaign marketing is your actual job.
Pricing is volume-metered and cheap at the low end: free for 3,000 emails a month capped at 100 a day, then $20 a month for 50,000 emails, $35 for 100,000, and a Scale ladder that runs to 2.5 million emails at $1,150. Overage is billed at $0.90 per 1,000 on the lower plans and falls to $0.46 per 1,000 at the top, so nothing gets throttled or dropped when you spike. Marketing contacts are priced separately, free to 1,000 contacts and then a $40 to $650 Pro band up to 150,000 contacts.
The company has raised roughly $21M including an $18M Series A led by Andreessen Horowitz, is based in San Francisco, and is small. That is the honest risk: you are buying critical delivery infrastructure from a young venture-backed startup rather than from AWS or Twilio. The counterweight is that Resend's whole reason to exist is that the incumbents got worse, and so far it has not repeated their mistakes.
Best for
Software teams that need reliable, well-instrumented transactional email from their own code, especially JavaScript and TypeScript shops that want React Email, and anyone leaving SendGrid or Mailgun because the console and the support got worse.
Not the right fit for
- Anyone whose actual job is email marketing; there is no automation builder, no behavioral segmentation, no CRM, and no ecommerce machinery, so buying Resend instead of a marketing platform means buying the wrong category of product.
- Cold outreach and purchased-list senders; Resend's acceptable use policy prohibits unsolicited email and the account will be terminated, so prospecting tools belong in a cold email platform with its own infrastructure, not here.
- Teams that need more than 30 days of message logs for compliance or dispute handling; retention is fixed at 30 days on every plan short of Enterprise, which is shorter than Postmark's configurable 365 days.
- Regulated buyers who need a named data residency guarantee, a long compliance paper trail, and a vendor with a decade of audit history; Resend is four years old and small.
- Very high-volume senders optimizing purely for cost per email; at millions of messages a month Amazon SES is roughly an order of magnitude cheaper, and the developer experience premium stops being worth it.
How it works
- 1
You add a sending domain in the dashboard and paste the DKIM, SPF, and DMARC records it generates into your DNS. Resend verifies them and reports the status, which is the step most teams get wrong on other providers and the step Resend has spent the most design effort on.
- 2
Your application calls the send endpoint with a from address, a to address, a subject, and either HTML, plain text, or a React Email component rendered server side. Official SDKs exist for Node, Next.js, Express, PHP, Laravel, Python, Ruby, Rails, Go, Rust, Elixir, Java, and .NET, plus a CLI and an SMTP relay for legacy stacks that cannot call an API.
- 3
Delivery events flow back to you through webhooks: delivered, bounced, complained, opened, clicked. The dashboard keeps a searchable log of every message for 30 days on all plans except Enterprise, with the raw payload, the headers, and the delivery timeline, which is what you look at when a customer says they never received the reset email.
- 4
For newsletters, Broadcasts adds an audience of contacts, a no-code editor, topic-based subscription preferences, an unsubscribe list, scheduling, and open and click reporting. Contacts can be added manually, by CSV, or through the API. This is broadcast sending, not lifecycle automation; there is a separate automation-runs meter for the simple sequences that do exist.
Feature breakdown
24 features in 5 modulesSending API
The core transactional surface, deliberately small.- REST send endpoint
- A single well-documented endpoint takes from, to, subject, HTML or text, attachments, headers, and tags, and returns a message ID you can trace through the logs.
- Official SDKs for thirteen stacks
- Node.js, Next.js, Express, PHP, Laravel, Python, Ruby, Rails, Go, Rust, Elixir, Java, and .NET, all maintained by the vendor rather than by the community.
- Batch sending
- Send many individual messages in one API call, which matters when a nightly job has to fire thousands of distinct notifications without thousands of round trips.
- Scheduled sends
- Queue a message for a future time through the API instead of maintaining your own delayed-job infrastructure.
- SMTP relay
- A standard SMTP endpoint for frameworks, CMSs, and legacy applications that cannot call an HTTP API, so Resend can sit behind WordPress or a Rails mailer without code changes.
- CLI and MCP server
- A command line tool for sending and inspecting from the terminal, plus an MCP server so AI coding assistants can work against your Resend account directly.
Email authoring
Where Resend's reputation actually came from.- React Email
- An open-source component library for building HTML email in React, maintained by Resend and widely used even by teams sending through other providers; it removes the worst of hand-writing table-based email markup.
- Broadcast editor
- A no-code visual editor in the dashboard for newsletters, changelogs, product launches, and investor updates, with test sends before you attach an audience.
- Full code control
- Because most sending is API-driven, you own the markup completely; there is no proprietary template language you have to fight to produce the exact email you want.
- Tags and metadata
- Attach arbitrary key-value tags to messages so the logs and webhooks can be filtered by tenant, feature, or campaign.
Deliverability and domains
The plumbing that decides whether the email arrives.- Guided DKIM, SPF, and DMARC setup
- The domain screen generates the exact DNS records, verifies them, and reports which ones are missing, which is the single most common cause of transactional mail going to spam.
- Multiple sending domains
- Three domains on Free, ten on Pro, and 1,000 on Scale, with an add-on at $20 per month per additional 100 domains, which matters for multi-tenant products sending on behalf of customers.
- Dedicated IPs
- $30 per month on Scale and above, available once you are sending at least 3,000 emails a day, which is the threshold below which a dedicated IP hurts rather than helps.
- Shared IP pools with sender vetting
- Most customers sit on managed shared pools; Resend polices what goes through them, which is why cold outreach gets accounts closed rather than merely throttled.
- Bounce and complaint handling
- Hard bounces and spam complaints are surfaced through webhooks and the dashboard so your application can suppress bad addresses.
Observability
What you look at when a customer says the email never arrived.- Searchable message logs
- Every message is retained for 30 days with its payload, headers, and delivery timeline, filterable by recipient, status, and tag.
- Webhooks
- Signed event callbacks for delivered, bounced, complained, opened, and clicked, so your own systems can react to delivery outcomes rather than polling.
- Delivery metrics dashboard
- Real-time delivery, bounce, and complaint rates per domain, which is how you notice a reputation problem before your users do.
- Broadcast analytics
- Open and click tracking, subscriber actions, and unsubscribe counts on marketing sends, tracked separately from transactional traffic.
Audiences and marketing basics
Enough to run a newsletter, not enough to run marketing.- Contacts and audiences
- Contact records added manually, by CSV import, or through the API, grouped into audiences that broadcasts target.
- Topics and preference management
- Recipients can subscribe to specific categories of marketing email rather than facing an all-or-nothing unsubscribe, which is genuinely better practice than most ESPs offer.
- Managed unsubscribe list
- Resend maintains the suppression list and honors it automatically, including List-Unsubscribe headers on marketing sends.
- Automation runs
- Paid plans include 10,000 automation runs a month, billed at $0.0015 per run thereafter, covering simple triggered sequences rather than branching lifecycle flows.
- AI credits
- Five on Free, 100 on Pro, 500 on Scale, used by the assistive features in the dashboard.
Use cases
4 documentedNext.js SaaS founder shipping authentication
Magic links and password resets have to arrive in seconds, the emails need to look like the product, and there is no time to hand-write table-based HTML.
React Email components render the templates in the same codebase as the app, the Resend SDK sends them in three lines, and the 30-day log answers every support ticket about a missing reset link.
Engineering team leaving SendGrid
The incumbent console is slow, the support queue is long, and nobody on the team can find out why a specific message bounced last Tuesday.
Resend's searchable logs and signed webhooks give the on-call engineer the delivery timeline for any message directly, and the SMTP relay makes the cutover a credentials change rather than a rewrite.
Multi-tenant B2B product sending on behalf of customers
Each customer wants notifications to come from their own domain, which means managing hundreds of verified sending domains and their DNS records.
The Scale plan carries 1,000 domains, with more available as a $20 per 100 add-on, and the domain verification API lets the product onboard a tenant's sending domain without a human touching the dashboard.
Small startup running a changelog newsletter alongside product email
Two thousand users want a monthly product update, and standing up a separate Mailchimp account for one email a month is overkill.
Broadcasts sends the changelog from the same contact base, with topics letting users opt out of updates without losing their transactional mail, and the marketing contact tier stays free below 1,000 contacts.
Pricing
from $0 for 3,000 emails a month, then $20 a month for 50,000 emailsTwo separate meters. Transactional email is billed on monthly send volume with per-thousand overage. Marketing email is billed separately on contact count. Neither meter charges for team seats.
| Plan | Price | Includes |
|---|---|---|
| Free | $0 per month |
The 100-a-day cap is the real constraint; a burst of signups can hit it long before the 3,000 monthly figure. |
| Pro | $20 for 50,000 emails, $35 for 100,000 emails per month |
The plan most small products land on; $35 covers a surprisingly large amount of product notification traffic. |
| Scale | $90 for 100,000 rising to $1,150 for 2.5M emails per month |
Scale at $90 for 100,000 emails costs more than Pro at $35 for the same volume; you are paying for the domain count, the dedicated IP option, and the cheaper overage curve. |
| Marketing Pro | $40 to $650 per month by contact count |
|
| Enterprise | Custom quoted |
|
Add-ons
- Dedicated IP ($30 per month): Scale and above, and only sensible above roughly 3,000 emails a day.
- Additional domains ($20 per month per 100 domains)
- Automation runs beyond 10,000 ($0.0015 per run)
Billing notes
- Transactional pricing is metered on emails sent, not on contacts stored, so an inactive user costs nothing until you email them; this is the structural difference from every contact-priced marketing platform in this category.
- Overage is billed rather than blocked on paid plans, at $0.90 per 1,000 on Pro and falling to $0.46 per 1,000 at the top of Scale. Nothing gets throttled when your traffic spikes, but nothing caps your bill either.
- The free plan is capped at 100 emails per day as well as 3,000 per month, so bursty traffic hits the daily ceiling first.
- Marketing contacts are a wholly separate line item; sending 50,000 transactional emails and running a 5,000-contact newsletter is $20 plus $40, not one bundled price.
- Message log retention is 30 days on every plan except Enterprise, and it is not purchasable as an add-on, which is a real limitation if you need older evidence of delivery.
- No annual discount is published; pricing is presented as monthly.
Value assessment: Modelled at the three volumes this directory uses, Resend's transactional meter behaves nothing like a contact-priced ESP. A product with 1,000 users sending each of them roughly three notifications a month is inside the free tier at zero. Ten thousand users at three emails each is 30,000 sends, comfortably inside the $20 Pro plan. Fifty thousand users at three emails each is 150,000 sends, which is $35 for the first 100,000 plus $45 of overage, or about $80 a month. Against Postmark that is roughly half the price at volume, against SendGrid it is competitive, and against Amazon SES it is about five times more expensive. You are paying a modest premium over the raw infrastructure price for a console you can navigate, docs you can read, and support that answers. For most small software businesses that trade is obviously worth it.
Strengths & limitations
Strengths
- The best developer experience in transactional email by a wide margin: small API, thirteen first-party SDKs, readable docs, and a dashboard that loads instantly.
- React Email is a genuine ecosystem contribution and makes building branded transactional templates in a JavaScript codebase pleasant rather than miserable.
- Volume-based pricing means dormant users cost nothing, which is structurally cheaper than contact-priced marketing platforms for product notification traffic.
- Domain authentication is guided rather than left to you, and the verification status screen catches the SPF and DKIM mistakes that quietly send transactional mail to spam.
- Overage is billed rather than blocked, so a traffic spike does not silently stop your password reset emails.
- Broadcasts with topic-level subscription preferences is better subscriber-preference design than most dedicated marketing platforms offer.
- Strongly capitalized for its size with $21M raised including an $18M Series A led by Andreessen Horowitz.
Limitations
- It is not a marketing platform. No automation builder, no behavioral segmentation, no branching lifecycle flows, no ecommerce integration, no landing pages, no CRM.
- Message log retention is capped at 30 days outside Enterprise, well short of Postmark's configurable 365 days, which is awkward for chargeback disputes and compliance evidence.
- No inbound email parsing, so if you need to receive and route replies programmatically you need Postmark, Mailgun, or SES Mail Manager alongside it.
- Dedicated IPs are Scale-only and gated at 3,000 emails a day, so a small sender who wants IP isolation cannot have it.
- No published data residency guarantee or regional hosting commitment, which will fail some EU procurement checklists.
- The company is four years old and small; you are trusting critical delivery infrastructure to a startup rather than to AWS, Twilio, or Sinch.
- Two separate meters for transactional and marketing means the bill is less predictable than a single contact-priced plan, and the Scale ladder is priced above Pro at the same volume, which confuses first-time buyers.
Head-to-head comparisons
5 alternativesResend vs Postmark
from $15 a month for 10,000 emails (Basic)Both are premium developer-focused transactional providers and both refuse cold outreach. Postmark wins on log retention (configurable to 365 days versus Resend's fixed 30), on inbound parsing, which Resend lacks entirely, and on institutional track record since 2010. Resend wins decisively on developer experience, SDK breadth, React Email, and price at volume: 150,000 emails is about $80 on Resend against roughly $80 to $200 on Postmark depending on plan. Choose Postmark if you need inbound mail or long retention, Resend if you are writing the integration today.
Full Resend vs Postmark comparisonResend vs Twilio SendGrid
from $15 a month (Marketing Campaigns Basic) or $19.95 a month (Email API Essentials)SendGrid is the incumbent and does more: transactional API plus a real Marketing Campaigns product with contact-priced plans, plus email validation and enterprise support tiers, all inside Twilio. Resend does one job and does it better, with a faster console and support that answers. Most teams migrating in either direction are moving away from SendGrid, not toward it. Take SendGrid if you want one vendor for transactional and marketing under a large parent company; take Resend if the integration experience and the debugging surface are what you care about.
Full Resend vs Twilio SendGrid comparisonResend vs Mailgun
from $15 a month for 10,000 emails (Basic)Mailgun offers more infrastructure primitives than Resend: full inbound routing, email validation as a metered service, longer log retention on Scale, and dedicated IPs from the 50,000 volume tier. It is also owned by Sinch and feels it, with a heavier console and an enterprise sales motion layered over the self-serve plans. Resend is cheaper at comparable volume, far nicer to integrate, and lacks inbound entirely. Pick Mailgun when you need to receive and route mail programmatically; pick Resend when you only need to send.
Full Resend vs Mailgun comparisonResend vs Amazon SES
from $0.10 per 1,000 emails a la carteSES is roughly five to ten times cheaper per email at $0.10 per 1,000 a la carte, and it is the price floor everyone else is measured against. What you pay for that is doing the work yourself: no usable log viewer, no template ergonomics, a sandbox you must apply out of, and an account that gets paused if your bounce rate crosses 5 percent or complaints cross 0.01 percent. Resend costs more and hands you observability, guided authentication, and a human to email. Under a million messages a month the difference is tens of dollars, and Resend usually wins on total cost including engineering time.
Full Resend vs Amazon SES comparisonResend vs Loops
from $49/mo (up to 5,000 subscribed contacts)Loops bundles transactional sending free into a contact-priced SaaS lifecycle platform, so one bill covers receipts, onboarding drips, and newsletters on a shared contact base. Resend is the opposite shape: a metered transactional API with newsletters bolted on. If lifecycle automation driven by product events is the reason you are shopping, Loops is the correct purchase and Resend will disappoint you. If you want the best possible sending API and already have your marketing tooling elsewhere, Resend is better at the narrow job.
Full Resend vs Loops comparisonImplementation & onboarding
- Setup time
- Under an hour for a first send, and typically a day to be fully in production. Verifying a domain takes as long as your DNS propagates; the SDK integration itself is a handful of lines.
- Learning curve
- Very low for anyone who has used an HTTP API. The genuinely new skill for most teams is email authentication, and Resend's domain screen teaches it as you go rather than assuming you already know.
- Onboarding
- Entirely self-serve on every plan short of Enterprise. There is no sales call, no onboarding fee, and no minimum commitment.
- Migration notes
- Migrating from SendGrid, Mailgun, or SES is usually a same-day job because the sending shape is identical: swap the SDK or point SMTP at Resend, re-verify the domain, and repoint webhook consumers. The parts that do not migrate are your historical logs, which stay with the old vendor, your suppression list, which you should export and re-import so you do not re-mail known bounces, and your IP reputation, which resets. Send a small share of traffic through Resend first and watch the delivery rate for a week before cutting over completely.

Frequently asked questions
10 questionsWhat is Resend?
Resend is a transactional email API for developers. Your application calls it to send receipts, password resets, magic links, and product notifications, and Resend handles delivery, domain authentication, bounce and complaint webhooks, and message logging. It ships official SDKs for thirteen languages and frameworks and maintains React Email, an open-source library for writing HTML email as React components.
How much does Resend cost?
Free covers 3,000 emails a month capped at 100 a day. Pro is $20 a month for 50,000 emails or $35 for 100,000. Scale runs from $90 for 100,000 emails up to $1,150 for 2.5 million, with cheaper overage rates as volume rises. Overage on Pro is $0.90 per 1,000. Marketing contacts are billed separately, free to 1,000 contacts and $40 to $650 for 5,000 to 150,000.
Is Resend a marketing platform?
No, and treating it as one is the main way buyers get this wrong. Broadcasts lets you send a newsletter to an audience with topic-based preferences and unsubscribe handling, which covers a changelog or an investor update. There is no automation builder, no behavioral segmentation, no branching lifecycle flows, no ecommerce integration, and no landing pages. If campaign marketing is your job, buy Mailchimp, ActiveCampaign, MailerLite, or Klaviyo and use Resend for the transactional half.
Can I send cold outreach through Resend?
No. Resend's acceptable use policy prohibits unsolicited email and purchased lists, and accounts caught doing it are terminated rather than warned. This is deliberate: Resend polices its shared IP pools so that everyone else's transactional mail keeps arriving. Cold prospecting belongs on a dedicated cold outreach platform running its own inboxes and domains.
Do unsubscribed or inactive contacts cost me money on Resend?
On the transactional side, no. You are billed for emails sent, so a user who never receives another message costs nothing to keep. That is the structural advantage over contact-priced platforms like Mailchimp and ActiveCampaign, where dormant subscribers keep inflating the bill. The marketing Broadcasts side does price on contact count, so the usual list-hygiene discipline applies there.
How long does Resend keep message logs?
Thirty days on every plan except Enterprise, which is flexible. You cannot buy more retention as an add-on. That is the shortest window among the premium providers: Postmark defaults to 45 days and can be configured up to 365. If you need older delivery evidence for chargeback disputes or compliance, log the message IDs and outcomes into your own database from the webhooks.
Does Resend support inbound email?
No. Resend sends; it does not receive. If you need to parse replies, run a support inbox programmatically, or route incoming mail into your application, you need Postmark's inbound parsing, Mailgun's inbound routes, or Amazon SES Mail Manager alongside it.
When should I use a dedicated IP on Resend?
Only above roughly 3,000 emails a day, which is exactly where Resend gates the $30 per month add-on. Below that volume a dedicated IP has too little traffic to build a warm reputation and will deliver worse than the managed shared pool. Most small businesses should stay on shared IPs, where Resend's sender vetting is doing reputation work on your behalf.
How does Resend compare with Amazon SES on price?
SES is far cheaper on paper at $0.10 per 1,000 emails a la carte, roughly five to ten times less than Resend. What Resend adds is a usable message log, guided DKIM and SPF setup, thirteen first-party SDKs, React Email, and support that replies. Below a million messages a month the absolute difference is tens of dollars, which is less than an hour of engineering time, so most small teams are better off on Resend.
Who owns Resend and is it a safe bet?
Resend is an independent venture-backed company founded in 2022 by Zeno Rocha and Jonni Lundy, based in San Francisco, with roughly $21M raised including an $18M Series A led by Andreessen Horowitz. It is well funded for its size but it is still a young startup holding critical delivery infrastructure, which is the honest risk versus AWS, Twilio, or Sinch. Keep your suppression list exportable and your sending abstracted behind an interface.
Editorial verdict
Resend is the best transactional email API to integrate today, and the reason is unglamorous: the docs are correct, the SDKs are first-party across thirteen stacks, the domain verification screen tells you exactly which DNS record is wrong, and the message log answers the support ticket in ten seconds. React Email alone has saved more engineering hours than the subscription costs. Buy it for product notification traffic, receipts, and authentication email, where volume-based pricing means dormant users are free. Do not buy it as a marketing platform: Broadcasts is a newsletter tool, not an automation engine, and you will end up paying for a second product anyway. The genuine cautions are the fixed 30-day log retention, the complete absence of inbound parsing, and the fact that a four-year-old startup now holds your password reset pipeline. At Resend's price and quality those are acceptable trades for most small software businesses, but abstract your sending behind an interface so switching stays a one-day job.
