Step 2: Delete or Archive Email
You can decide whether to delete or archive the email. Business emails, in particular, should always be archived to ensure traceability.
Step 3: Mark Advertisement as Spam
If you recognize that an email is an advertisement, you can mark it as Spam. This is usually done under the "Delete" menu option. Here you have the opportunity to label emails as advertisements, which will move them to the spam folder.

Use the "Clean Up Conversations" option to remove all the emails you no longer need, including duplicate emails. Additionally, you can also tidy up the folders to maintain better oversight.

Step 7: Recognize International Emails
Additionally, you can identify emails in unknown languages and move them directly to the advertisements folder or even delete them. This is especially useful if you frequently receive emails in a language you do not understand.
Step 8: Permanently Remove Deleted Emails
If you want to permanently delete emails, go to the deleted items. Hold down the Shift key to select the last email, or press Ctrl + A to select all emails, and choose the "Delete Permanently" option.
