Increase email deliverability in your wordpress website (WP SMTP plugin setup)


Hello again! We will solve problems in wordpress not sending emails properly. This is through the plugin called WP SMTP, which sends email instead of the default wordpress mail function. This means that an email will be sent to receiver on your behalf, using the service who already has a good reputation on email servers. Thus giving you a higher chance of delivering the emails.

WordPress email sending problems

The problem is when wordpress sends email to your website email or customers, the server would not receive the email.


It’s because wordpress sends email to the server without identity. It’s like sending letter to somebody without a return address. What happens is that the server would not receive the email because it doesn’t know where it came from.

Thus affects:

  • Alerts
  • Woo commerce orders
  • Password resets
  • Other Plugin related emails


  1. Using a dedicated third party emailing service.
  2. Using a plugin that can send an email on our behalf.
