New at Posteo: The Cleanup Tool for email attachments
Created at 19.June 2025, 14:00 | Category: Info
Dear Posteo customers,
We have released a new feature: Our Cleanup Tool. Now you can tidy up your email account more efficiently and free up storage space quickly.

Maybe it has happened to you before: You wanted to reduce the storage space used in your email account and deleted a lot of emails but barely any storage space was freed up. This is because most emails are very small in size. It’s common for only a few large messages with file attachments to occupy a lot of storage space.
With the Cleanup Tool, you can quickly identify what is eating up your storage space. You can immediately see which attachments are using a lot of storage space. It is often sufficient to delete a few of the largest attachments in your account to have enough storage space available again for a long time. The highlight: You can keep the associated emails – and, if needed, you can download attachments before deleting.
With the new Cleanup Tool, you no longer need to laboriously search through your email account for large emails or book more storage space. This saves you time and money. It also helps the environment if less data is stored online.
All attachments in a compact overview
You can find the Cleanup Tool via “Attachments”. When selecting it, all attachments will be prepared in a clearly structured list. The largest attachments will be displayed at the top and the smallest further below.

Additionally, the overview allows you to filter by file types such as PDF files, images, presentations, spreadsheets or text files.
You can also only display attachments found in individual folders.
You can now quickly and easily delete attachments to free up storage space.
If an attachment is deleted from an email, the Cleanup Tool will automatically insert a brief note to the associated email. This note contains the name of the deleted file as well as the date of deletion. This way, you can remember that the email originally contained an attachment. If you also no longer need the email, of course you can also delete the entire email.
Furthermore, you can download the files before deleting them with just one click.
The new Cleanup Tool is available to you at no additional cost. It expands on the attachment browser with our integrated photo stream which you can also find in Posteo webmail via “Attachments”.
Privacy notice: New features are always designed by us so that no personal data is collected in the background. This reinforces your right to informational self-determination. The Cleanup Tool is developed solely by Posteo without any third parties involved. The preparation of attachments in a list view only occurs upon your request – and the results are only temporarily stored locally in your browser. We do not store this information on our servers and it is also not passed on.
Best regards,
Your Posteo Team
