S/MIME (Secure/Multipurpose Internet Mail Extensions) is a cryptographic method to securely encode and sign emails. It allows users to protect their content from unauthorized access and confirm the sender's authenticity. To use S/MIME, it is necessary to purchase a digital certificate and share it with EmailLabs to correctly configure it in our system.

A certificate assigned to your e-mail address can be found in the SMTP accounts tab > Settings > S/MIME.

For more information about the pricing of implementing the S/MIME certificate, contact our consultants at support@emaillabs.io
