I run a few SaaS products. For a long time I was paying around $300/month across two separate tools: one for transactional email and another for marketing and sequences.
The cost was annoying. But the real problem was the manual work. Opening the tool, building templates, setting up drip campaigns... as a developer, that always felt like a waste of time.
The turning point came from a conversation with Pedro Campos, founder of templated.io. He told me he had given up on finding an email tool because none of them had MCP support. When he said that I thought: if even we, as developers, do not want to do this manually, nobody does.
I searched the market. Found nothing like what I had in mind. So I wrote the first line of code for Sendkit.
Here is what I learned along the way:
The AHA moment has to be fast
I used PostHog to track where users were getting stuck. The AHA moment for Sendkit is sending the first email. So I rebuilt the entire onboarding around that. You grab your API key, we show you the SDK, and you are sending in literally one minute.
Nobody wants to build email sequences manually
That is why Sendkit is MCP native. You tell your AI agent to create an onboarding sequence for your SaaS and it builds everything: templates and automations. I recorded a demo where I create a 14 day onboarding with 7 emails for my own product Changelogfy. The MCP visited the site, understood the colors, grabbed the logo, understood the product and built all the templates by itself. What would have taken me days was done in 3 minutes.
Suppression lists should be automatic
Nobody cleans their list. So the list has to clean itself. A bounce goes straight to suppression. Marked as spam, same thing. Your sending reputation stays protected without you having to think about it.
Real email validation
We also have a separate validation API. You send an address and we tell you if it is real, disposable, catch-all or a role email like admin{@} or info{@}. Use it at signup to block fakes before they hit your list.
After a closed beta with over 5 million emails sent, we opened to everyone. Already past 100 customers.
If you are tired of paying for multiple tools that still require manual work, check out Sendkit. 3,000 emails free per month, no credit card required.
