Background story

"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, we decided to fix that and built Sidemail."

Nothing could beat Sidemail

“We were absolutely blown away by how awesome the Sidemail offering has been for us at Quicka. We looked at rolling our own and leveraging existing providers but nothing could beat Sidemail for simplicity and ease of use for beautiful transactional emails. Thanks Patrik and the team!“

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.”

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 supports dark mode from get-go and is ready for different email clients. All you have to do is upload two different logos for light and dark themes.“
