GPG Mail: Unable to encrypt or decrypt with general key

before purchasing the support plan of this plugin, I have a question for general use. My situation is the following:

My team uses a single gpg-key pair for communicating with a company, which in turn also uses only a single key-pair.
However, when I am trying to send an encrypted mail to one of our clients, the encryption icon is greyed out (clearly, because his mail does not match the one in the key). Is there a way to get around this, so that I can encrypt my mails with any key that I like?

Have a nice day,

    Hi Nils,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    Are you able to send an encrypted and signed email to yourself?

    If that works can you please double check with your contact that you have the correct public key of them and that the email address used for that key perfectly matches the email you are using in the "To:" field of your draft.

    that is actually the problem. The email for the recipient does not match the email of that key. This is, because the whole company uses a single key for decryption.

    Thank you! That is exactly what I was looking for.

    One more thing. Is the subscription permanently or per year or per month?

    Following is an explanation how GPG Mail Support Plan works and how long it is valid:

    Our FAQ ( states: "A release of a new major version of GPG Mail will most likely coincide with a new major macOS release, but certainly not more often than that.“

    You can think of it as a yearly subscription, but it’s not exactly that. GPG Mail 4 supports macOS 10.13 - 10.15. GPG Mail 5 adds support for macOS 11 Big Sur. GPG Mail 4 will no longer receive updates and you can decide if you want to stay on GPG Mail 4 or if you want to keep continue getting updates and purchase a support plan for GPG Mail 5. Each macOS release could have the consequence that we have to completely re-reverse and rewrite major portions of our code. We wanted to keep the option open to support new OS releases with the existing GPG Mail, if we see that Apple didn’t change the internals that much. Does that make sense?

    Best regards,

    That totally makes sense. Thank you.

    Regarding the link you sent me, what am I supposed to enter for fingerprint?

    The fingerprint would be the fingerprint of the public key you want to assign to the domain in question. Make sure to enter it without spaces.
