By far the easiest email service

“Sidemail is by far the easiest email service I have used. I was up and sending welcome emails in 10 mins. That’s it. It can send transactional, marketing and newsletter emails. It support dark mode from get go and is ready for different email clients. All you have to do is upload two different icons for light and dark themes.“

Everything sorta just works

“I wanted something a bit easier so I didn’t have to do all the template legwork, and this project, I really wanted it to look gorgeous... I spent a couple of hours standing up some html templates in their editor. From there, it’s as easy as calling up the template name and passing in some variables and everything sorta just works.“

Exactly what I needed

“My app messages sent with PHP mail() ended up in spam. I’m no email expert, and Sidemail seemed to do exactly what I needed, so I replaced mail() with a code snippet from Sidemail, and it just worked. I had some trouble setting up DNS, so I contacted the Sidemail support and quickly got a helpful response that resolved my issue.”

Meet the founders

Hi there! We’re a tiny 2‑person startup, 100% bootstrapped. When we needed Sidemail, it didn’t exist. Integrating transactional emails into an app felt like reinventing the wheel. To sent product updates, it was a nonstop struggle with unnecessarily complicated marketing tools. So in 2018, we challenged ourselves to fix that — build Sidemail. In the words of Ross Edgley, we were naive enough to start, stubborn enough to finish.
