Sending encrypted mail messages through DekkoCORE.

There are two ways to compose a Mail message:

Open the Contacts dropdown, hover over a contact and press the Mail icon

Contacts panel with a pink arrow pointing to the envelope Mail icon beside contact Darren Miles, next to the Chat icon.

Select Mail in the navigation bar, then press Compose

Left navigation panel with Mail selected (arrow), showing Inbox, Sent, and the blue Compose button at top of the message list.

If you have All Hubs selected, you’ll need to choose a Hub to send the Mail message from.

    Mail To field showing the contact "John Smith" as a recipient and the typed text "Darr" auto-completing to "Darren Miles" in a dropdown, with CC and BCC links above.

    Users who are already in the Hub will auto-complete when you enter their name or email address. You can also enter an unregistered address, and that individual will be sent a registration invite, after which they can read the message.

    Unregistered users will appear with their full address:

    Recipient field showing "John Smith," "Darren Miles," and "sally@newco.io" as tags, with CC and BCC links at top right.

  2. Enter a subject and message body:

    Email compose box showing "Meeting minutes" subject field and a sample message body addressed to John, Darren, and Sally, signed by Mary.

  3. Attach from files (content already uploaded to the Hub) or Attach files (from your computer's storage).

    Mail message attachments have no file size limits.

    Email compose area showing a signed-off message from Mary and two attached files: "01_01_2023 meeting minutes.pdf" and "product info pack.pptx".

    1. When you are ready, press Send:

      The message thread will appear in your Sent items.
