## About

WP Mail SMTP is a WordPress plugin that fixes email deliverability by sending site email through an SMTP or email API provider such as SendLayer, Brevo, Amazon SES, Gmail, Mailgun, Postmark or SendGrid. It adds email logs, failure alerts, backup connections, smart routing and open and click tracking.
The affiliate program runs on the plugin's own affiliate system and pays 20% of a referred customer's first order, up to about $19.80 on an Elite license. Commissions are paid in the monthly payout once the referred account has stayed active for 37 days, applications are reviewed by hand within about 48 hours, and pay-per-click bidding needs written permission.
