Auto increment collection variable

I would like to make automation tests in Postman. But some requests needs unique values to run successfully. So I would like to know if there is some variable which I can add to the values which will ensure unicity. Lets imagine email field which will contain something like

    "email": "aaa@{{unique}}.com",

It can be increment, timestamp or whatever like that. But I need to have always new value in there for all requests, and dont care about setting up the value. Is there something like this? Thanks for your time.
