New: Posteo doubles storage space to 4 GB

Created at 04.February 2026, 10:00 | Category: Info

Dear Posteo customers,

We have good news: Starting immediately, the price of €1 per month includes more storage space – we are increasing it from 2 GB to 4 GB.

The adjustment applies to all Posteo mailboxes: both for new and existing customers.
The storage usage bar has already been adjusted accordingly. If a lower percentage of occupied space is displayed, don’t worry: nothing has been deleted. Your storage space has simply been increased.

If you have booked additional storage space, you will no longer pay the surcharge for the first 2 GB (€ 0.25/month per GB) in future.
The monthly fees for mailboxes have already been adjusted; you do not need to do anything.

Why we can offer more storage space for 1 EUR

This upgrade has also been made possible by you – or rather, by our new Cleanup Tool, which we introduced six months ago.
With this new feature, you can clean up your mailbox and free up used storage space with just a few clicks.
The Cleanup Tool has been very well received. So well, in fact, that we can now offer more storage space at no extra charge.
We had been thinking about this for a long time, and it was one of the reasons we introduced the new Cleanup Tool last June.

We would like to thank all Posteo customers who are already using the Cleanup Tool.

Use the Cleanup Tool and free up storage space

Even though it’s still a little early for the annual spring cleaning, we would like to take this opportunity to promote the Cleanup Tool once again. You can find it under “Attachments.”
Select it, and all the files in your mailbox will be displayed in a clear list. The largest files are shown at the top, with smaller ones further down.
You can filter the overview by file types such as PDF files, images, presentations, spreadsheets, text files, and folders.

Often, deleting just a few of the largest attachments in your mailbox is enough to free up enough storage space for a long time to come. The best part is that you can keep the corresponding emails and download the attachments with a single click before deleting them, if necessary.

If you delete an attachment from an email, a brief note is automatically inserted into the corresponding email. It contains the name of the deleted file and the date of deletion. This allows you to see that the email originally contained an attachment. You can, of course, also delete the entire email.

You no longer need to spend time cleaning up your mailbox or purchasing additional storage space. This saves you time and money. And it also helps protect the environment, as less data is stored online.

Best regards,
Your Posteo team
