Email is different kind of thing to different people. Solving all email problems with extentions is complicated.(Standards).
There are tools that take one problem or weakness from email and address that specifically.
Like Slack is for Internal communication with in organization.
Formal address the one use case of email, external whenever(not real time) communication.
You cannot replace your entire email with formal as a whole.
Just like Slack is Slack and not an email extension for internal communication. Formal tries to solve problems in one specific use case of email. External communication.
For example, You have already adapted slack and now your major use case of email is external communication then you may take that responsibility from your email and adapt Formal.
If you think Formal adds value to your life then
1. Register for Formal. (30 Seconds) 2. Set a permanent Vacation Responder in your email to contact you through Formal. (30 Seconds) (Only humans read this responder and act) 3. Share your Formal Id with anyone instead of your email id.
Thanks again for your time and reply.
