The plugin is developed by WP Manage Ninja, which is best known for many popular plugins such as Fluent Forms, WPPayForm and Ninja Tables. We first heard about FluentSMTP when we bought a licence of their latest plugin. All customers of FluentCRM, the email marketing automation plugin for WordPress, should receive a free FluentSMTP licence worth up to $149 per year. However, WP Manage Ninja ditched this plan at short notice and have decided to offer the SMTP plugin for free as a way of giving back to the WordPress community. There will be no pro version!

But now let’s take a quick look at the plugin.

Instead of using the standard PHP mail function in WordPress to send emails, you should use an external SMTP server (Simple Mail Transfer Protocol) for this task. This effectively increases the chances that your emails will end up in the recipient’s inbox and not in the SPAM folder.

FluentSMTP comes with the following features:

  • Real-time email delivery
  • Email routing
  • Unique Feature: Multiple SMTP connections, e.g. for sending transactional and marketing emails
  • Native integrations with six email service providers (ESPs):
    • Mailgun
    • Pepipost
    • SendGrid
    • Sendinblue
    • Amazon SES
    • SparkPost
  • Use any SMTP server
  • Email logs

The plugin also has a detailed reporting function. Finally, it allows you to resend emails that did not get through due to an SMTP issue.
