Download the trial
The whole program · 150 messages · no account, no card
This is Grezzio itself, not a cut-down preview. Every market card, the business search, the AI personalisation, the compliance report — all of it works. The one limit is that the trial sends 150 messages. After that the program keeps everything you built and asks you to buy a licence to carry on sending.
Grezzio 7.9.5 — trial
Windows 10 or 11, 64-bit · 40 MB · includes the place index for all 53 markets, so search works offline from the first run.
What Windows will say, and why
The installer is not yet signed with a code-signing certificate, so Windows SmartScreen will show a blue panel saying it protected your PC, with Don’t run as the default button. Click More info, then Run anyway.
We would rather tell you this here than let you meet it alone after downloading. A certificate is on the way; until it arrives, this is what an unsigned installer from a small company looks like on Windows, whatever is inside it.
What happens after 150 messages
Sending stops and the program says so, in the middle of the screen, with the two purchase options. Nothing is deleted: your lists, templates, signature, mailbox settings, opt-outs and compliance log all stay exactly where they are.
Buying a licence does not mean setting anything up again. You install the full version, paste the licence key into Settings → Data & program, and carry on from where the trial stopped.
The count is kept outside the program folder, so reinstalling or downloading a fresh copy does not reset it. That is deliberate and we would rather say it plainly than have you find out by trying.
What the trial does not limit
- All 53 markets. Every ruling, citation and source link, exactly as in the full version.
- The business search. The full place index of 329,266 places across 53 countries, and all 40 industries.
- Your own AI key. Anthropic, OpenAI or Google, if you want personalisation. Without a key the plain template still goes out.
- Mailboxes, warm-up, opt-outs, bounces, backups, exports. Nothing here is held back.
Before you send anything
Two things are worth doing first, and both are free. Run the sending-domain check on this site — it reads your SPF, DKIM and DMARC records and tells you what is missing. Then read the market card for the country you intend to write to. Thirty-four of the 53 markets require consent before a first message, and the program will tell you which.
When you are ready
Solo is €99 for one workstation, Team is €279 for up to ten. One payment, no subscription, free rule-set updates as laws change. Prices exclude VAT, which is added at checkout at your country’s rate.
