Not mass mailing but business proposals from one company to another, on infrastructure we build and control. Most competitors rent someone else's service and live on a shared reputation that neighbours ruin. We build your own.
Letters go out and nobody replies, and it is unclear whether they even arrive.
The domain used for sending is the same one your contracts and invoices come from.
A rented service shares its reputation with everyone else on it.
The base was bought as a file and half the addresses bounce.
The same letter goes to everyone, with a company name substituted into a template.
Nobody measures deliverability, so failures look like a market problem.
The main domain never takes part in sending. Everything else follows from that rule.
A private club for business owners: live offline case reviews in central Moscow, a table assembled around your request, business games and access to a team of practitioners. Everything discussed stays inside the circle.
