The development of MailCheck is a hobby and I'm spending a lot of my spare time on enhancing it and answering user's questions.
The needed tools for development this free software are no longer free for me.
If you are satisfied with MailCheck and want to support its further development, then I would be happy about a little donation.
This is absolutely optional and has no advantages for you - MailCheck can be used free of charge without any obligations.
Thank you for your support!
