How long do emails remain in gmail all mail folder

Gmail's "All Mail" folder is a special folder that contains all emails in your Gmail account, including emails that are archived, labeled, or in the trash. The retention period for emails in the "All Mail" folder depends on several factors, including:

1. Gmail's default retention period: Gmail typically retains emails in the "All Mail" folder for 30 days before automatically deleting them. This is because Gmail's default setting is to automatically delete emails that are older than 30 days and are not marked as important or starred.
2. Account settings: You can change the retention period for your Gmail account by going to Settings > Forwarding and POP/IMAP > Delete messages older than [X] months. You can set the retention period to be anywhere from 1 month to 10 years.
3. Label settings: If you have labeled emails in the "All Mail" folder, they will remain in the folder until you manually delete them or the retention period expires.
4. Trash and spam: Emails that are moved to the Trash or Spam folders will be deleted after a certain period of time, which is typically 30 days. However, you can change this setting in your account settings.
5. Google's data retention policies: Google has its own data retention policies, which may affect the retention period for emails in your Gmail account. For example, Google may retain emails for longer periods of time if they are part of a legal investigation or if they are required by law.

In summary, the retention period for emails in the "All Mail" folder in Gmail can vary depending on your account settings, label settings, and Google's data retention policies. However, as a general rule, emails in the "All Mail" folder will typically remain in the folder for at least 30 days before being automatically deleted.
