Using a web browser to send messages with Mailock
Visit our secure mail site, and click on ‘Sign In’ at the top left.
This will take you to the compose page where you can start creating your secure message:

1) The "From:" field will show your main email address by default, but you can switch it to any other linked address if you want the email to appear as if it's coming from them instead
2) Enter the email address of your recipient. If you want to send it to more than one person just put a ; between each one
3) Add a subject title for your email
4) Add attachments securely by clicking or dragging files to this area
5) Compose your message by typing, pasting text, adding images, or using the toolbar for formatting
6) By default, a copy of the message will be securely sent to your email inbox for your records. Untick the box if you don't want to receive a copy
7) When you’re ready, click on ‘Send’

- Pro users will only see the options that have been enabled by their Company Administrator
If the challenge is optional. it means the recipient is part of your trusted community.
