Badex
Signature
Email signatures, centralized.
Microsoft 365, cPanel, Plesk, Roundcube, Directadmin, Thunderbird — one platform to manage professional DKIM-signed email signatures for all your users, regardless of their email setup.
"We wanted every employee to have the same professional signature without chasing people to set it up themselves. With Badex it just works — new people get the right signature automatically, and I don't think about it anymore."
"Setting up company-wide signatures used to be a manual job. Badex handles it centrally for our whole Microsoft 365 tenant — reliable and low-maintenance."
"For a team our size we didn't want anything complicated. Badex gave us clean, uniform signatures for everyone with almost no effort on our side."
Built for IT administrators, agencies, and hosting providers who need centralized signature control across any email infrastructure.
The only signature platform that injects professional DKIM-signed signatures into emails sent from any SMTP server — not just M365.
No plugins, no Outlook add-ins, no per-user installs. Works at the server level for both M365 and generic SMTP.
No per-user fees. Fixed monthly price per tier. Choose the plan that fits your email infrastructure.
The only platform that covers both Microsoft 365 and generic SMTP
