Pay for the emails you send, not the size of your list
100,000 subscribers emailed weekly is about 400,000 emails, roughly $40 a month on Amazon SES. List-priced newsletter tools charge hundreds for the same sends.
Everything you need to send, nothing you don't
- Broadcasts: Write in a visual editor and send newsletters and campaigns to your whole list or a segment.
- Sequences: Welcome series, onboarding and drips that run on their own.
- Transactional email: Receipts, resets and alerts from one REST API, with the same templates and tracking.
- Your own sender: Bring Amazon SES or any SMTP provider. Your reputation and your rates stay yours.
- Built for AI agents: An MCP server lets Claude, Cursor and other assistants manage contacts, templates and sends.
- Open source: The core is open source and self-hostable, so you're never locked in.
Your own SES, without the deliverability homework
Moving to Amazon SES usually means wiring up bounces, complaints and suppression yourself. SendLit does it for you.
- Bounces and complaints, handled: Connect your SES notifications and SendLit records hard bounces and spam complaints automatically.
- Automatic suppression: Bounced and complaining addresses are suppressed, so you never mail them again and your reputation stays clean.
- One-click unsubscribe: Every marketing email carries the List-Unsubscribe headers Gmail and Yahoo require (RFC 8058).
Embed email in your platform
Course, community and creator platforms can give every customer their own email marketing. Provision teams with one API call, set per-team sending quotas, and drop SendLit's React editor and blocks into your app.
Add newsletters to your product in a few lines
