Unitpost/Guides

WordPress

WordPress sends mail via PHP's `mail()` by default, which most hosts deliver poorly. Route it through Unitpost SMTP with a plugin like WP Mail SMTP.

What are the SMTP settings?

Hostsmtp.unitpost.com
Usernameunitpost(always this literal value)
PasswordYour Unitpost API key(must carry emails:send)
Port (STARTTLS)587(or 2587 if blocked)
Port (implicit TLS)465(or 2465 if blocked)
From addressAny address on a verified domain

How do I set it up?

  1. Install an SMTP plugin

    From Plugins → Add New, install and activate WP Mail SMTP (or a comparable SMTP plugin).

  2. Choose the "Other SMTP" mailer

    In the plugin settings, pick the generic Other SMTP option (not a named provider).

  3. Enter your Unitpost SMTP settings

    SMTP Hostsmtp.unitpost.com
    EncryptionTLS (STARTTLS)
    SMTP Port587
    AuthenticationOn
    SMTP Usernameunitpost
    SMTP PasswordYour Unitpost API key
    From Emailyou@yourdomain.com (verified)

    Store the API key in the plugin's password field. Set the From Email to an address on your verified domain.

  4. Send a test email

    Use the plugin's Email Test tab to send yourself a message, then confirm it in your Unitpost Activity view.
