Send later free version

Hello,

I use the free version of Mailspring. I understand that the pro features are available but limited. I sent two emails with the “send later” option but both were sent immediately.
Can you tell me clearly what the limitations of mailspring free are?
It’s really not clear.

  1. The pro features don’t work in the free version, so why offer them without a warning message!
  2. the features are limited to a few uses per day or week or month… In that case, a countdown would be useful.

Thank you for your reply.
