Send WordPress email over SMTP

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.

1. 1

   Install an SMTP plugin

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

2. 2

   Choose the "Other SMTP" mailer

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

3. 3

   Enter your Unitpost SMTP settings

   SMTP Host	smtp.unitpost.com
   Encryption	TLS (STARTTLS)
   SMTP Port	587
   Authentication	On
   SMTP Username	unitpost
   SMTP Password	Your Unitpost API key
   From Email	you@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. 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.
