The 96% problem

Mailchimp charges $1.40
for an email AWS sells for a fraction of a cent.

Per-contact pricing was a clever billing trick when email was hard. AWS SES is now $0.10 per 1,000 sends — and SES Mailbox is the dashboard, automations, and analytics layer that turns it into a real product.

A real product. Not a wrapper.

Everything Mailchimp does. None of the per-contact tax. Built by people who hand-rolled SES for years before deciding to do it properly.

What you get

Built for marketers.
Priced for founders.

Drag-and-drop builder

Compose responsive emails with our visual editor. 40+ starter templates, dark-mode preview, every major email client tested. Or paste raw HTML.

Lists that update themselves

Dynamic segments rebuild on every event. "Purchased in 30 days, opened 3+ emails, tagged VIP" — written once, updated forever.

Deliverability that proves itself

SPF, DKIM, DMARC checked on every send. Real-time bounce + complaint webhooks via AWS SNS. Auto-suppression keeps your sender score pristine.

Visual flow builder

Welcome series, abandoned cart, win-back, post-purchase upsell. Trigger on any event from your CRM, Stripe, or Shopify.

Real-time, real numbers

Every open, click, bounce, and complaint streams back from SES the moment it happens. No 30-minute batch delay.

Your AWS. Your reputation.

FAQ

Questions, answered.

How is SES Mailbox 96% cheaper than Mailchimp?

Mailchimp and Klaviyo charge per contact — even contacts who never receive an email. AWS SES charges $0.10 per 1,000 emails actually sent, and we charge a flat $9.99/mo for the platform. At 50,000 contacts emailed once a month, you'll pay about $15/mo total vs. Mailchimp's $350/mo. The bigger your list, the wider the gap.

Is SES Mailbox affiliated with Amazon AWS?

No. We're an independent product that uses AWS SES as the sending infrastructure. You connect your own AWS account, your AWS bill is yours, and your sender reputation belongs to you. Think of us as the dashboard, automations, and analytics layer that AWS SES doesn't ship with out of the box.

I'm currently on Sendy / self-hosted. Why switch?

Sendy is great until it isn't — bounce processing breaks, the cron job dies, the VPS needs upgrading. SES Mailbox is the managed equivalent: same AWS SES leverage, but with native event handling, a modern UI, dynamic segmentation, automations, and a team behind it. We have a one-click Sendy importer in the migration tool.

What about deliverability? Will Gmail filter me?

AWS SES is one of the most trusted sending networks in the world — used by Netflix, Reddit, and Duolingo. We layer SPF/DKIM/DMARC validation, real-time bounce + complaint webhooks via SNS, and automatic suppression on top. Most customers see better inbox placement after switching, because they're sending from their own verified domain rather than a shared Mailchimp pool.

Do I need technical chops to set this up?

No. Our 5-step onboarding walks you through creating an AWS account, generating SES credentials, and verifying a domain (we generate the exact DNS records to paste into your registrar). Most customers are sending their first campaign within 30 minutes.

Can I migrate my Mailchimp lists, templates, and automations?

Yes. Our one-click Mailchimp importer pulls audiences (via API or CSV), recreates templates, and reproduces common automation flows (welcome series, abandoned cart, win-back). The migration tool runs in your dashboard — no engineering required. Most teams migrate in under 30 minutes.

What's the catch with the free plan?

None. The Free plan is permanently free — you get unlimited subscribers, 1 campaign per month, the drag-and-drop builder, basic analytics, and community support. We make money when teams grow into Pro ($9.99/mo) for unlimited sends and automations. No credit card required to sign up.

Is my data safe?

Yes. Your subscribers and campaign data live in our managed SOC 2 Type II-certified database; your emails are sent through your own AWS account. We’re GDPR-ready, sign DPAs on the Pro plan, and you can export every byte at any time. We never sell or share subscriber data.
