What Happens to Emails in the Spam Folder?

Time period for which spam emails are saved

Updated 1 month ago

The Spam folder stores emails that are automatically flagged as suspicious.
This helps protect your inbox from unwanted or potentially harmful messages.

Spam filtering is automatic and cannot be turned off. It aims to block spam but may occasionally misclassify emails.

Why Emails Are Marked as Spam

Emails are usually marked as spam for one or more of these reasons:

  • Similar emails were previously marked as spam by users.

  • The sender has a poor sending reputation.

  • The message contains suspicious links, attachments, or formatting.

  • Email authentication is missing or misconfigured for the sending domain (SPF, DKIM, or DMARC).

 

Moving Emails Between Spam and Inbox

Your actions help improve spam filtering accuracy:

  • Moving an email out of Spam trains the system that similar messages are legitimate.

  • Moving an email to Spam trains the system that similar messages are unwanted.

These actions help train the spam filtering system over time.
Changes are not immediate and may not affect every future message.

 

Automatic Deletion From Spam and Trash

To prevent storage issues, automatic cleanup is applied.
Emails in the Spam and Trash folders are automatically deleted after 30 days.

This cleanup helps ensure your mailbox storage is not exceeded due to spam or deleted messages.
Deleted emails cannot be recovered.

You can also delete emails immediately by clicking Delete while viewing messages in the Spam folder.
