What is Grezzio?

Grezzio is a Windows desktop program for B2B cold outreach. It finds companies by reading the open Overture Maps dataset - no per-lead fees and no monthly credits - verifies addresses before sending, and keeps replies in the same program as threads.

Before a message goes out, it checks the recipient's market against a built-in rule set covering 53 markets. Every market carries the statute behind its rule and the date the rule was checked. Markets that require opt-in will not start until the sender confirms the decision is theirs.

Sending runs from the user's own mailbox over SMTP. There is no subscription, no cloud account and no server belonging to the maker anywhere in the path. An AI key is optional and used only for personalisation; without one, a plain template is sent.

What it does not do: it does not guess a second address at the same company after a bounce, it does not send in opt-in markets without explicit confirmation, and it does not give legal advice - it shows the statute and the source, and the decision stays with the sender.

A free trial of the full program, limited to 150 sent messages, needs no account and no card.
