Colldly
Cold email that reads their website before it writes
Colldly finds the companies you need, reads their website, writes each one a personal email, warms up your mailboxes, sends at the right time and puts every reply in one inbox. You just talk to people who want to talk. From 19€/month, 200 free credits.
I'm Michal. I build websites and e-shops for small companies, and every one of them asks the same thing: "OK, the web is nice. But where do I get new clients?"
Cold email works. But the way most people do it? 3/10. One tool for company data, one for warm-up, one for sending, ChatGPT in another tab, and in the end everyone gets the same "Hi {first_name}, I noticed your company..." Straight to spam. Or worse, straight to trash.
So I built Colldly. One app, the whole thing:
finds the companies (our own company database, Google Maps, directories)
reads each company's website and writes an email about THEM, not about you
warms up your mailboxes, rotates them, keeps the limits, checks SPF, DKIM, DMARC
sends at the right time, follow-ups go by themselves
every reply lands in one inbox, AI sorts who's interested
Real numbers from the whole platform since June 2026. They're live on the website, refreshed every 10 minutes, nothing made up:
39,771 emails sent
98.6% delivered
35% open rate
3.6% of companies replied
Is 3.6% a crazy number? No. Is it real? Yes. I'd rather show you real than pretty.
200 free credits, no card. First campaign in 10 minutes.
Tell me straight: what would stop you from trying it? I read everything and I answer everything. Personally.
PS: When you write to support, you write to me. The guy who built it :)
