What our customers are saying

See how developers, marketers, and product teams use Sendkit to send emails that reach the inbox.

We needed something simple for onboarding emails. The MCP integration is what got us, we connected it to Claude and had our whole email sequence done in maybe 15 minutes. Looked around before and couldn't find that anywhere else.

Migrating our SMTP relay took maybe 20 minutes. Swapped the host, dropped in the API key, done. Bounce handling and suppression lists just work. We had a whole week blocked for that and didn't need any of it.

We use Sendkit for appointment reminders, post-treatment follow-ups, stuff like that. Set up all the automations myself in one sitting, no developer needed. Our clients actually started rebooking more once we stopped forgetting to follow up.
