The Constant Contact alternative built for modern teams
Constant Contact is a solid marketing email tool — but it has no transactional API, no free plan, and no developer experience worth building on. Sendbound replaces it and adds everything it was missing.
Built for a better email experience
No transactional email — at all
Constant Contact is a marketing email tool with no transactional API. You can't send a password reset, order confirmation, or magic link through Constant Contact. You'd need a second platform. Sendbound handles both with one API key.
Built for the 2000s, not 2020s
Constant Contact's interface was designed when email marketing meant drag-and-drop newsletters. Sendbound is built for modern teams: TypeScript SDK, React Email templates, CI/CD-friendly, and a dashboard that doesn't feel like a legacy app.
No free tier, even for developers
Constant Contact has no free plan — you're in a paid trial from day one. Sendbound gives you 3,000 emails per month permanently free, with no credit card required, so you can integrate and validate before spending anything.
Deliverability without the manual work
Constant Contact gives you basic unsubscribe handling. Sendbound monitors blocklists in real time, rotates DKIM automatically, and walks you through DMARC and BIMI setup — the kind of deliverability intelligence that keeps your emails out of spam for good.

Developers who made the switch
Constant Contact was fine for our monthly newsletter but the moment we needed to send transactional emails we hit a wall. Sendbound does both and the API is night and day better.
We moved off Constant Contact after pricing went up for the third year in a row. Sendbound costs less, sends more, and has an actual developer API we can build on.
