SMTP Mailer
SMTP bulk mailer for Windows
Send through any SMTP server, including your own domain, with server rotation and personal fields.
Already have mail servers, or email on your own domain? SMTP Mailer sends your campaign through them, with rotation across servers, a daily limit for each one and the pauses that keep your domain's reputation healthy.
Use your hosting provider's mailboxes, your company mail server, or any service that gives you SMTP details: host, port, username and password.
What it does
Any SMTP server
Host, port, SSL/TLS, username and password. If it speaks SMTP, it works.
Server rotation
Add several servers or mailboxes and spread the sending between them.
Limits per server
Each server gets its own daily cap, matched to what your host allows.
Connection test

Personal fields
Personalise the subject and text from your list's columns.
Send log
