cost calculator.

How AWS SES pricing actually works.
It's almost embarrassingly simple — and the simplest thing in your whole martech stack.
Cost calculator FAQ
How accurate is this calculator?
Prices are based on public list pricing as of May 2026 for Mailchimp Essentials, Klaviyo Email, SendGrid Marketing Campaigns Essentials, and Constant Contact Lite. AWS SES prices are from the published AWS SES pricing page.
Does the $0.10 per 1,000 emails include bounces?
Yes. AWS SES charges per attempted send. SES Mailbox automatically suppresses hard bounces and complaints in real-time so you don't waste sends on dead addresses.
What's the difference between Free and Pro?
Free is permanently free — unlimited subscribers, 1 campaign per month, drag-and-drop builder, open + click analytics. Pro is $9.99/mo and adds unlimited campaigns, automations, dynamic segments, A/B testing, full REST API, webhooks, team access, and priority support.
