emailengine VS sync-engine

When I started with https://emailengine.app, a similar product, I also considered releasing it as a SaaS. But looking at the competition, it seemed too complicated for me (just look at the compliance list for Nylas Email API https://www.nylas.com/security/#compliance ). Will be interesting to see how it works out for you. Good luck!

EmailEngine has all the code public [1], even though it is not open-source but is source-available. Some core parts I even published under the MIT license, like the IMAP client library I built from scratch to serve the special requirements EmailEngine has for IMAP access [2]

My thinking has always been that those who try to hack the license validation stuff and replace the missing build pipeline were never going to be my customers in the first place, so every second I would spend on them is a wasted effort.

Seems open-source to me.

Well, I for one, hope that email stays as complicated as described in the post. Otherwise my project that simplifies access to email accounts (https://emailengine.app) would get no traction :D

I'd like to know if anyone here can share some experience using https://emailengine.app in a larger environment, e.g. managing / watching 100-200 email accounts and processing ~50.000-100.000 mails per day?

I had the same issues when I started with https://emailengine.app - just like Ghost, it’s an app written in Nodejs. I tried multiple distribution options at first and finally went with complete self containment. All modules are pre-installed during the publishing step and thus the user never needs to run npm. Or if you download the “compiled” single binary version you don’t even need node as it’s bundled with the binary (I use the pkg module to bundle these executables). So upgrading is just downloading and replacing the old version files with new ones.

The dowside - no sane way to use compiled dependencies, everything has to be vanilla javascript.

Only project I know is the Close.io fork of open source Nylas Engine (the original project was discontinued years ago) https://github.com/closeio/sync-engine
