A: Yes, you can replace your ESP with Dreamlit in most cases.

Dreamlit handles both transactional emails (like signups, receipts, notifications) and things like broadcasts/newsletters, so for many small businesses it can fully replace tools like Mailchimp, SendGrid, etc. You don’t need a separate ESP subscription—we handle the sending infrastructure for you (via AWS SES under the hood). The main requirement is that your data lives in a database (like Supabase/Postgres), since that’s how Dreamlit knows who to email and when.
