Requesting a receipt in Webmail, is a good way to confirm the recipient has received your message.
To request a receipt for your message, follow these steps:
- Open a message. This could be a new message, or one you are replying to or forwarding.
- Select the three dots next to the From line (or Options in Classic mode).
- Select Request read receipt.
Note: You can also enable read receipts on all messages by default by selecting the Settings icon, opening the Writing Email tab, and checking Request read receipts (or Preferences > Mail > Composing Messages > Always request read receipt in Classic mode).
