MemberPress Mailster has been tested up to WordPress 6.7 and PHP 7.4. We recommend always testing on a staging site before installing on live production.

I build sites for clients — is one purchase enough?
One purchase covers unlimited installations. The GPL v2 or later licence that MemberPress Mailster is released under has no domain or site limits — neither does digitalgpl.

Is it safe to buy a GPL plugin from a third-party store?
Yes. The GPL licence was created specifically to allow this. Any developer who releases software under GPL grants everyone the legal right to redistribute it. That is the foundation of the open-source WordPress community.
