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.
Send Cold Email from Your Own SMTP
ColdMailer sends through an inbox you own: Gmail, Outlook, SendGrid, Amazon SES or any SMTP provider. Your emails, your domain, your reputation, and replies come straight back to you.
Why bring your own SMTP
Shared sending infrastructure means shared reputation, and one bad actor on the pool can sink your deliverability. Sending from your own mailbox keeps that entirely in your hands.
- Connect any SMTP provider: host, port, username and password
- We open a real connection and log in before the inbox can be used, so a wrong password is caught here and not halfway through a campaign
- The password is stored encrypted and never shown again
- Your own From name and address on every message
- Two inboxes on Starter, unlimited on Pro and Enterprise
A campaign sends through the one inbox you pick for it. ColdMailer does not rotate between mailboxes and does not warm them up.
