The Mailchimp alternative
that actually saves you money.
SES Mailbox is a like-for-like Mailchimp replacement — campaigns, audiences, automations, analytics — built on AWS SES so you pay $15/mo for what Mailchimp charges $350/mo to do.
SES Mailbox is cheaper from day one.
Mailchimp Essentials pricing vs SES Mailbox Pro + AWS SES, assuming one campaign per month to your full list.
Mailchimp Essentials pricing as of May 2026 · SES Mailbox Pro $9.99/mo + AWS SES at $0.10/1,000 sends, one campaign/month
It's not just the price.
The pricing model is broken
Mailchimp charges by contact count — including contacts who haven’t opened an email in three years. SES Mailbox charges $9.99/mo flat. Inactive subscribers cost zero. AWS SES costs $0.10 per 1,000 emails actually sent.
Shared IPs hurt deliverability
Mailchimp's outgoing emails leave from a shared IP pool. If a spammer two senders down poisons the IP, your inbox placement suffers. With SES Mailbox you send from your own AWS SES account.
No subscriber-count penalty
On Mailchimp, growing your list punishes you — $135 at 10k becomes $800 at 100k. On SES Mailbox Pro the platform fee stays $9.99 forever. Scale without dread.
Mailchimp switching FAQ
The exact questions we hear from teams considering the move.
How much does Mailchimp cost in 2026?
Mailchimp's Essentials plan starts at $13/mo for 500 contacts and scales steeply: $135/mo at 10k, $230/mo at 25k, $350/mo at 50k, and $800/mo at 100k. The Standard plan (which adds the visual flow builder and behavioral segments most teams need) is 30-50% more expensive on top.
What's the same cost on SES Mailbox?
SES Mailbox Pro is $9.99/mo flat, every list size. AWS SES costs $0.10 per 1,000 emails sent. So at 50,000 contacts emailed once a month: $9.99 + $5 = $14.99/mo total. The platform fee never grows with your subscriber count.
Can I migrate my Mailchimp audience and templates?
Yes. Our one-click Mailchimp importer pulls audiences via Mailchimp's API, recreates templates from their HTML source, and reproduces common automations. Most teams complete the full migration in 15-30 minutes.
Will my deliverability drop after switching?
Almost always the opposite. Mailchimp sends from shared IP pools where your reputation is mixed with thousands of other senders. SES Mailbox sends through your own AWS SES account so your reputation is isolated. The median open-rate lift we see across migrations is 3-6 percentage points.
Is SES Mailbox missing any major Mailchimp features?
Two: Mailchimp's landing page builder (we focus on email — pair with Webflow or Framer for landing pages) and the website/CRM bundle on Mailchimp Premium ($350+/mo).
