Product information


The Digital Mailbox from Correos is the best way of storing your digital documents as you’ll be able to access them quickly and easily from any device, whenever and wherever you want. All you need is an internet connection and your login details.

It is a secure Cloud storage space which enables you to safely store all your communications with other users, companies and Public Administrations signed up to the service, in a single location without the risk of receiving spam or unwanted communications.

You can subscribe to the companies you are most interested in receiving digital documents from, thus doing away with the need for hard copies. Your smart mailbox will automatically help you to classify them in folders, so you don’t have to worry about a thing.

It also enables you to create your own personal folders so you can upload any documents you wish to keep and access them at any time, thanks to its search engine which you can use to find them quickly and easily. What's more, you can download them and share them with other users of the Digital Mailbox by creating links, or via email or social networks.

You will soon be able to use the Digital Mailbox to send comments to the sender on the documents you have received, and open up communication threads between you where you can include text and attach documents.

It will include the digital signing of documents, so you can sign and return any contracts or policies the companies may send you. To do this, you need to have a digital certificate issued by a Correos Post Office.   

It will enable you to send and receive legally valid certified documents via electronic means.

And it will make it possible to send large documents to any Public Administrations signed up to the service directly from wherever you are, in a digital format, thanks to the Cloud Pendrive option. To complete the process, you need to go to a Correos Post Office to make the payment and get your receipt. 


The basic Digital Mailbox service is free of charge. For other functionalities, please see our prices.
