    Supplier

Tell it once who's real.

Add your boss, your colleagues, your suppliers — with their real addresses. Mailgate remembers, so it always has someone real to compare against.

  • Add anyone: boss, colleague, supplier
  • Saved once, checked against forever

The moment it starts.

An email asks for a payment, a bank change, a gift card, or a login — and it feels slightly off. Or someone on your team forwards it and asks, “is this real?”

Fwd: Urgent — updated bank details

Sample

To: Priya Achar

“Hi Priya, please send this week's supplier payment to the account below instead — I'm travelling.”
