Send workflow
How it works
1. Encrypt
Start a secure email from your desktop email client or your web browser. Set a challenge so only the right people gain access.
2. Connect
Recipients click ‘Open’ on the notification delivered to their inbox. They’ll answer your challenge, or if they're trusted, they can read right away.
3. Engage
If recipients need to respond to a secure message, they can use Mailock to compose, attach, and reply using their existing email address and account.
Authentication
Make sure the right
person is reading
Set read challenges for recipients
- SMS: Send a one-time code to your recipient's mobile device.
- Q&A: Ask your recipient a question only they could correctly answer.
- Unipass ID: Allow financial professionals to verify their ID using Unipass.
Secure replies
Share the power
to email securely
Recipients reply securely for free
It’s not enough to protect information one way. Mailock makes it easy for your recipients to read and reply. They’ll even get some free secure sends in case they need to deliver sensitive information to others.

Prevention
Prevent data loss
with trigger words
Get ‘before you send’ alerts
We're only human - sometimes we don’t think twice before hitting 'send'. If your email contains any of your preset trigger words, Mailock won’t let you send it unsecured without checking you're 100% sure.
