One of the four isn't a person.

Shared inbox

The whole team in the same inbox

Laura and Martín open sales@ with their own accounts. What one reads shows as read for the other.

  • Nobody answers twice.
  • The history belongs to the inbox, not the person.

Domains

Nobody ever took a quote from a hotmail address seriously.

No domain yet? Search for your company's name and email starts with it. Nothing to set up and nobody to call.

The domain is separate and the registrar charges it: the price depends on the ending, and you see it before you buy.
