Email tool needs for a bootstrapped micro SaaS

A has outgrown the free tier of its tool and needs to move. Many older email tools feel overloaded with features and become expensive once the contact list passes a few thousand people.

The needed tool should have a reliable API and webhooks so app events can trigger emails automatically. Pricing must stay reasonable after 5,000 or more subscribers so it does not hurt margins.

Strong matters because emails need to reach inboxes, not spam folders. Large enterprise-style builders are not important for this use case.
