Can I switch from Mailchimp without losing my list?

Yes. Export a CSV from Mailchimp, import into Senderkit, regenerate templates with AI in Cursor, point your DNS, and send. Most teams finish in an afternoon.

Do I need to know how to code?

No. Cursor and VS Code are free downloads with a chat box — you type plain English, the AI writes your email. See /why-ai-ide for the full walkthrough.

Where does my subscriber data live?

In your own Neon Postgres database. Senderkit reads it only at send time. You can export or move anytime because the data is already yours.

Email, quietly done well

Your list grows. Your bill doesn't.

The newsletter tax

Paying $100/mo because 4,000 ghosts sit on your list?

Most platforms charge for every contact, even the ones who unsubscribed in spirit three years ago. Your audience grew. Your bill exploded. You did nothing wrong — you just got punished for succeeding.

See what you save

Pay for what you send. Not who's on your list.

Senderkit charges by emails sent — the actual cost. Inactive subscribers, bouncers, lurkers: free to keep on your list.

Grow the list. Not the bill.

Re-engagement campaigns work. Old leads come back. Import everyone — you only pay when you actually send.
