PGP password request

Love the app but I am over having to put my password in for my G-mail account every time I send an email. A box opens with a request to insert my password for the PGP #.
It is only on send, receive is not a problem, and it is only with this app, other apps are okay can you help?

Did you setup any encryption keys when you setup your Gmail account ?

Also in eM Client “Menu / Settings / Signing and Encryption / Account Policies” do you see “Include certificate keys in outgoing messages” and if you do is it enabled / checked ?
