How to Send Emails With Confidential Mode in Gmail

Sending to a new email adds it to your contacts so that it will auto-complete next time.

You can undo the sending of an email within a short time frame.

Use Gmail to send from any email address you own, even non-Google ones.

Once you’ve added a new email address to send from, change your From field to use it.

Set up an email so that it gets sent out later, at a time you specify.

Confidential mode lets you prevent recipients from forwarding, copying, printing, or downloading your email. You can also set an expiration date and require a passcode for recipients to view your email.

Templates are a way of avoiding repetitive typing of messages that you have to send often.

A read receipt is a confirmation that the recipient has read your email.
