Sendinc
The simple way to send a secure email
About Sendinc
Sendinc is a web-based encrypted email service that lets you send secure messages from your existing email address, with no software required for recipients. It offers a free individual plan, paid Pro and Corporate plans with message retraction and auditing, a Microsoft Outlook add-in, and SMTP and REST APIs for adding encryption to your own applications. Sendinc is part of VIPRE Security Group.
