Loved by developers and teams
See how teams are using SendKit to power their email infrastructure.
We switched to SendKit for our transactional emails and saw deliverability jump from 94% to 99.2%. The API is clean, the docs are great, and we were integrated in under an hour.
SendKit's SMTP relay was the easiest migration we've done. We just swapped the credentials and everything worked. The real-time webhooks for bounce handling saved us weeks of work.
The campaign builder is surprisingly powerful for a developer-focused tool. We run our entire newsletter and drip sequences through SendKit now. The analytics are exactly what we needed.
What sold us was the pricing transparency. No per-contact fees, no surprise charges. We send 500K transactional emails a month and the cost is predictable every single time.
We needed both transactional and marketing email in one platform. SendKit handles our password resets, order confirmations, AND our weekly newsletter. One dashboard, one bill, zero headaches.
The automation workflows are a game-changer. We set up onboarding sequences that trigger based on user events via the API. Our activation rate improved 40% in the first month.
