Why Mailuno exists.

Cold email is broken in two opposite directions. The big sending platforms turned it into a spreadsheet of {first_name} variables and sequence builders, optimized for volume — and the email those tools send embarrasses anyone who has to put their name on it. The other direction is hand-writing every email yourself, which is the only way to make it good but the slowest possible way to get to a meeting.

We built Mailuno because we kept hitting the same wall: we'd buy lists, write sequences, and watch reply rates collapse the moment we scaled past 50 prospects. The emails were generic because they had to be — no human can read 500 prospect websites in a day. But an AI can. So we made one that does.

Mailuno reads each prospect's site, writes a custom email referencing what's actually there, and sends it from the inbox you already use. No templates, no shared sending infrastructure, no {first_name} mail-merge fields.

We're a small team in Toronto. If you want to chat, email hello@mailuno.io — a real person reads it.
