Paid services for ZTmail come with a 7-day money-back guarantee. You can request a hassle-free refund on the official website's application page within 7 days of purchase. Upon refund, the email certificate corresponding to the purchased service will be revoked immediately and cannot be restored. Free email certificates will not be affected, though users may need to manually set their default encrypting certificate if the current default happens to be the revoked paid certificate.
Once the certificate is revoked, all signed and encrypted emails previously sent using this certificate will display a "Certificate Revoked" or "Invalid Signature" prompt to recipients verifying the digital signature. The digital signatures on these emails will become permanently invalid.
Recommendation: Please try the free version to experience the core features before upgrading to a paid plan.
