Send your first email

Write a message, send it with a short undo window, and reply or forward on the web.

This page covers the web app. The apps follow the same steps with their own compose screen.

Write and send#

  1. Select Compose in the sidebar, or press c when you are not typing in a field.
  2. Enter one or more addresses in To. Select Cc or Bcc to add those fields.
  3. Add a subject and write your message. The toolbar has the usual formatting, links, emoji and an attach button.
  4. Select Send.

After you select Send, a notice appears for 10 seconds with an Undo button. Undo cancels the send and nothing leaves your account. On the web, the message is only handed to the server when that window ends.

While you write, SipherMail saves a draft automatically. You will see "Saving draft..." in the window header.

Attach files#

Select the paperclip, or drag files onto the compose window. A "Drop files to attach" panel appears while you drag.

Reply and forward#

Open a conversation and use Reply, Reply All or Forward under the message. The original message is quoted for you.

Where your mail goes#

Sent mail appears in Sent. Unsent drafts are in Drafts. Messages you scheduled for later wait in Scheduled, see Scheduled send.
