First of all: Register your personal Tuta email address.
Then follow these easy steps to forward all emails from Posteo to Tuta:
Open Posteo in a browser and log in.
Open 'Settings'.
Click on 'My account'.
Open the menu item 'Forwarding'.
Click on 'Add new forwarding'.
Here you can enter your new Tuta email address to forward all incoming emails.
Confirm your entry by clicking on 'Save'.
From now on all emails sent to your Posteo account will be automatically forwarded to Tuta. You can inform important senders of your new Tuta email address and delete unimportant ones. This way, once you stop the auto-forward in Posteo, you will have a much cleaner inbox and get rid of all the unwanted newsletters that have accumulated over the last couple of years.
Welcome to the encrypted side!
Tuta is open source so security experts can verify the code that protects your emails. Our Android app is Google-free making Tuta the best open source email service.
With its all-round end-to-end encryption and its clear focus on open source, Tuta is the best email provider when it comes to convenience, security and privacy. We have replaced the need for IMAP by building the Tuta desktop clients for Windows, Linux and Mac OS that also support offline mode. Our next development steps include conversation view and email import. Our vision with Tuta is to become a full-fledged email alternative with a calendar, notes, cloud storage - everything encrypted by default.
