Built for inbox placement, not spam folders
Bring your own SMTP, let AI write a message for each prospect, and see the delivery result for every one.
AI personalization
Every email is uniquely written from prospect data, not a merge-tag template that screams "mass send".
Bring your own SMTP
Send from your own Gmail, Outlook, SES, or SendGrid accounts. Your domains, your reputation, your control.
A result for every prospect
Every message is recorded as sent or refused, with the reason your mail server gave, so you know exactly what left and what did not.
Cold Email Software That Writes Every Message Itself
ColdMailer is cold email software for people who already have a list. You paste it in, the AI writes a separate subject line and body for each prospect, and the campaign goes out through a mailbox you own.
What you get
- AI personalization: a unique subject and body per prospect, written from their company, role and your own context note
- Bring your own SMTP: Gmail, Outlook, Amazon SES or any provider, so the sending domain and the reputation stay yours
- Your copy, your call: read and edit any message by hand before it goes out
- A result per prospect: sent or refused, with the reason your mail server gave
- One flat plan: no per-inbox seat fees
What ColdMailer does not do
It does not find prospects for you. There is no lead database, no LinkedIn scraper and no email finder: you bring the list. It also does not warm mailboxes, rotate between them or send follow-up sequences. It writes and sends the first message, well.
