Let AI write it
The AI row under the message helps you write:Signatures
In Settings → Signatures, create one or more signatures with rich text or your own HTML. In Composing, choose whether your signature is added to new messages, replies and forwards.Read receipts

- The sent message shows when it was first opened, when it was last opened, and how many times.
- You get an alert when it’s read, which takes you straight to the message.
- To ask for receipts on every new message, turn on Settings → Composing → Ask for a read receipt by default. You can still switch it off per message.
Read receipts rely on the recipient’s mail app loading images. Some people block images, so a message can be read without a receipt.
