How BooleanSMTP sends through MailerSend
Through the Custom SMTP connection
In BooleanSMTP, add a mailer, choose Custom SMTP, and enter MailerSend’s SMTP server below with your MailerSend SMTP login. Logging, the fallback, retries and alerts work exactly as they do for every other connection.
| SMTP host | Port | Encryption |
|---|---|---|
| smtp.mailersend.net | 587 | TLS |
- Username
- The SMTP username MailerSend generates for your domain (Domains → your domain → SMTP)
- Password
- The password generated with it, shown once
MailerSend accepts SMTP on port 587 only.

Before you connect
Verify your domain in MailerSend and create SMTP credentials for it: an SMTP username and password.
Setup guide: Custom SMTP connectionsPair it with a fallback
Pair it with a second provider as the fallback so your site keeps sending if the domain or account needs attention.
When MailerSend refuses a message, BooleanSMTP tries your fallback connection at once, logs which one delivered it, and alerts you on Slack, Discord or Telegram only if every attempt fails. See the whole path
What MailerSend receives
Only what sending needs: each message (recipients, subject, body, headers, attachments) and the credentials you enter for the connection, sent to MailerSend when WordPress sends an email. BooleanSMTP stores those credentials encrypted in your own database. Read MailerSend’s terms and privacy policy.
