In case there are questions, concerns, comments or ideas (be they positive or negative, or something you might think I could improve or learn from), do please feel free to contact me through any of the following methods (email prefered). I am always happy to discuss things so that things can become better.
I keep work, projects/hobby and private strictly separated and thus communications which try to come through the wrong channel are silently rejected. Thus please use the proper channels.
My preferred way of contact is per email at: Jeroen Massar <email@example.com>.
While I am present on various social networks, email is a much better way to contact me as I do not regularly check social networks.
One can also use the vCard containing my contact details or scan the QR Code on the right.
Like most other people I don't like spam, as such that address is filtered by the excellent SpamAssassin. The policy is set to reject all viruses and spam during SMTP-DATA thus I won't see them but the sender will receive a NDR indicating that it was rejected and the reason why. PGP signing and encrypting your email ensures that the message passes. Don't forget to publish your PGP key in the PGP Keyservers if you want answer though.

My PGP keyID is 123421B735578C46 but due to collisions better check the full fingerprint below or use the QR Code to import it to your device. My old keyID was 333E7C23, still active but should not be used anymore.

As secure communications platform I have chose Threema. From independent audits, it looks like they are doing the right thing, and as they are in Switzerland, I can easily pay them a visit. One can ask for my Threema-ID using a PGP crypted message if wanted.
