welcome to the GPGTools support platform.
If you want to test your setup you can always send us a test email. It seems you are currently in decrypt only mode. You can use GPG Mail in trail mode for 30 days and then decide if you want to purchase GPG Mail Support Plan.
Once the trial expired you will be in Decrypt Only Mode. You will always be able to decrypt encrypted messages. Encryption and signing of new message as well as verification of signatures will no longer be supported.
