Visual instructions


Aliases are not supported by the standard email application in Android.

If you like, you could install other email programs, which often offer aliases, as well as many other functions.

For example, “K-9 Mail” is worth mentioning. As well as aliases, it also supports “Push-Mail”, so that messages come to your Posteo account without delay.

For “K-9 Mail” we also offer specific instructions, which can be viewed here: How do I set up Posteo in K-9 Mail (Android)?
