Learn how an automatic reply works
Your automatic reply starts at 12:00 am on the start date and ends at 11:59 pm on the end date, unless you end it earlier.
In most cases, your reply is only sent to people the first time they message you.
Someone can get your reply more than once if:
- The same person contacts you again after four days and your automatic reply is still on.
- You edit the automatic reply.
- If someone gets your initial automatic reply, then emails you again after you edit the reply, they get the updated email.
Tips:
- To prevent an automatic reply in a conversation thread, add a subject line to your reply. When you add a subject line, the recipient receives your reply in a separate email.
- Emails sent to your spam folder or addressed to a mailing list that you subscribe to don't get your reply.
