I have a subscription to Grammarly, and I find it very useful. Even typing this note Grammarly pops up because it’s in my Google Chrome. 
Is there a way to make Grammarly work inside of eM Client?

Isn’t Grammarly a browser extension? But whatever it is, eM Client does not support add-ons. Sorry Paul.

Thank you Gary. No, it’s for windows and plugs into word, outlook or browsers. It’s really a great little tool. Also, thank you very much for the help with the iCloud Calendar and contacts and so on - everything is working perfectly.

If em Client had a grammar tool or even a better spell checker that would be awesome - but it is still hands down the best email platform I have ever used - just wish it came in an app for the iphone.
