The short answer
Both sides assessedAWeber compared with Sender
Sender is dramatically cheaper: a free tier at 2,500 subscribers and 15,000 emails against AWeber's 500 and 3,000, and paid plans starting at $9 to $15 against AWeber's $15 to $30. Sender also includes transactional email, which AWeber does not. What AWeber has is twenty-eight years of operating history, a much better support reputation, Stripe-backed selling pages, and RSS blog broadcasts. If budget is the constraint, Sender wins outright. If you want a vendor that will still be there and answering the phone in ten years, AWeber.

Strengths and limitations
AWeber
Strengths
- A free tier that is genuinely usable at 500 subscribers and 3,000 emails a month with automations, landing pages, and forms intact rather than stripped out.
- Bootstrapped and founder-owned since 1998 with no acquisition, no venture capital, and no private equity, which is the strongest pricing-continuity story in this category.
- Support has a long-standing reputation for being fast and human, including phone support and 24/7 priority on Plus.
- Unsubscribes stop counting toward your billed total, so the invoice tracks your actual active audience rather than accumulating dead weight.
Limitations
- The send multiplier caps frequency: ten times subscribers on Lite and twelve on Plus, which rules AWeber out for daily newsletters.
- Lists bill separately and are never deduplicated across, so a multi-list structure quietly multiplies the invoice.
- Automation is shallow next to ActiveCampaign, Klaviyo, or GetResponse, with limited branching and no predictive or advanced conditional logic.
- Expensive per subscriber relative to MailerLite, EmailOctopus, and Sender for what the email functionality alone provides.
Sender
Strengths
- The most generous free tier in the category: 2,500 subscribers and 15,000 emails a month with automation, landing pages, and popups intact rather than stripped out.
- Paid plans starting at single-digit dollars, with 30 percent off the first year, undercutting almost every competitor at the same list size.
- Transactional email API and SMTP included on every plan including free, which no other budget marketing platform offers.
- Automation workflows available on the free plan, where most competitors reserve them for paid tiers.
Limitations
- Pricing above the entry point is set on a slider rather than published as a static table, which makes budgeting for a large list harder than it should be.
- Automation is competent but a clear tier below ActiveCampaign, Klaviyo, and Omnisend on conditional logic and ecommerce personalisation.
- A team of roughly thirty people supporting over 180,000 accounts means email and chat support rather than a phone line, with phone support only on Enterprise.
- The transactional feature is a convenience rather than infrastructure: no message stream separation, no inbound parsing, and nothing resembling Postmark's or Mailgun's logging and observability.
Pricing compared
AWeber
Subscriber-based subscription with a monthly send allowance set as a multiple of subscriber count. Two self-serve tiers plus a managed done-for-you service. Price steps at subscriber bands.
- Free$0
- LiteFrom $12.49 billed annually, $15 monthly at 500 subscribers
- PlusFrom $19.99 billed annually, $30 monthly at 500 subscribers
- Done For YouAbout $20 a month plus a $79 one-time setup fee
Modelled at this directory's three reference points: at 1,000 subscribers you are in the band above 500, so roughly $20 to $25 on Lite and $35 to $45 on Plus depending on the exact step, with the free plan covering you entirely up to 500. At 10,000 subscribers it is $100 on Lite and $135 on Plus, with monthly send allowances of 100,000 and 120,000 respectively. At 25,000 it is $210 and $250, and at 50,000 AWeber moves into the high hundreds; check the current ladder because the upper bands are revised. Against MailerLite, EmailOctopus, and Sender, AWeber is expensive for what the email alone does. Against Constant Contact it is broadly comparable and includes more per tier. Against GetResponse it is cheaper at the entry but capped on sending where GetResponse is unlimited. What the premium buys is a genuinely good free tier, a support organisation with a long reputation, landing pages and Stripe-backed selling included, and a vendor that has not changed hands in twenty-eight years. If you value continuity and human support over feature depth or price per contact, it is defensible. If you are optimising cost per subscriber, it is not the cheapest option on this list.
Sender
Subscriber-based subscription with a monthly send allowance set as a multiple of list size, priced on a slider rather than in a published static table. Prepaid email credits are available as an alternative for occasional senders.
- Free Forever$0
- StandardFrom $9
- ProfessionalFrom $15
- EnterpriseCustom
At the volumes this directory compares, Sender is the cheapest credible option on the list. A 1,000-subscriber list is entirely free, including automation, landing pages, and popups, where Constant Contact would charge $30 to $110 and AWeber $20 to $45. A 10,000-subscriber list moves onto a paid tier whose price the slider sets from the $9 and $15 entry points, and which in practice lands well below the $120 to $275 Constant Contact charges and the $100 to $135 AWeber charges at the same size. Fifty thousand subscribers likewise sits far below the $430 to $575 range at Constant Contact. The send multipliers of twelve and twenty-four times are competitive, sitting between Constant Contact's ten to twenty-four and AWeber's ten to twelve. What the low price does not buy is depth: the automation is a tier below the serious platforms, the reporting is thinner, there are no events or webinars, and support is a small queue rather than an organisation. For a business whose email needs are a newsletter, a welcome flow, a cart recovery sequence, and occasional SMS, Sender delivers all of it for less than anything else here.
Editorial verdict on each
AWeber
AWeber is the stable, unexciting, human choice in a category full of churn. It has been owned and run by the same founder since 1998, has never been acquired or repriced by a new investor, answers the phone, offers a free tier that is actually usable at 500 subscribers, and does not count your unsubscribes toward the bill. For a coach, consultant, blogger, or owner-operated small business that wants a newsletter and a welcome sequence to work reliably for the next decade, that is a genuinely good set of properties. It is not the best value per subscriber and it is not the most capable platform here. The send multiplier of ten to twelve times your list rules out frequent sending, the automation is shallow next to GetResponse or ActiveCampaign, and the per-list billing quietly multiplies your invoice if you organise with several lists instead of tags. MailerLite and Sender both give you more email for less money. Buy AWeber when vendor stability and support quality matter more to you than feature depth or cost per contact, and consolidate to a single tagged list on day one.

Best ValueSender is the best answer in this category to the question of how little you can pay. The free tier at 2,500 subscribers and 15,000 emails a month, with automation workflows, ten landing pages, popups, and a transactional API included, is more than several competitors give you on a paid plan, and the paid tiers start at single-digit dollars with SMS and A/B testing added. For a solo operator, a small ecommerce store, or any business under a few thousand subscribers, it is very hard to justify paying Constant Contact ten times as much for something that does the same job less generously. The limits are honest ones. The automation is a tier below the serious platforms, the reporting is thin until the Professional plan, there are no events or webinars, and roughly thirty people are supporting over 180,000 accounts, so support is a queue and the integration ecosystem is small. The transactional feature is a convenience, not infrastructure, and should not replace Postmark or Resend for a real dependency. Pricing above the entry point also lives on a slider rather than a published table, so read it for your own list before budgeting. Within those limits, this is the most email per dollar available to a small business today.
