S/MIME reminder is a very simple, free service.

If you’re using S/MIME certificates for encrypted messaging via e-mail your certificates will expire some day.

Simply send an e-mail to [email protected] (don’t forget to send your public S/MIME certificate with it) and we’ll remind you 30, 14, 7 and 1 day before the expiration to renew your e-mail S/MIME certificate.

That’s it!

Simple. Secure. Helpful. 🙂
