# Open source HTML email editors

A casual web search for 'open source html email editors' gives you a ton of results. Most of these are not truly open source or are stripped down versions. So we've compiled a list of truly open source html email builders. 

We have listed only the ones that fit most conditions below. One star is assigned for meeting each condition.

1. Must be fully open source. The rule is you should be able to get the source code and integrate it in to your own application.
2. There must be a fully working demo. 
3. Must have proper documentation for integration.
4. Able to send a test email.
5. \>= 1000 Github stars.
