How to Fix WordPress Contact Form Not Sending Email with SMTP

Not Sending Email with SMTP
Having problems with receiving email notifications from your WordPress contact form? Well, you shouldn’t panic. This is a very common issue among WordPress users.

Fortunately, an easy fix exists.

SMTP (Simple Mail Transfer Protocol) is the best solution for WordPress users searching for reliable email deliverability. An effective way of fixing issues related to SMTP is by using plugins.

Before looking at how to fix WordPress contact form not sending email with SMTP, let’s first have a closer look at why WordPress is not sending emails.

Why WordPress Is Not Sending Emails

WordPress utilizes the PHP mail function in order to send emails generated by any contact plugin such as WPForms. To reduce spam, email providers regularly checks whether an email originates from the source it claims to be emanating from.

For instance, assuming yahoo.com is your email server, but your email asserts that it’s been sent from your site’s domain, chances are high that the form notification shall be blocked prior to even reaching the spam folder.

That explains why utilizing the default PHP email function is discouraged and instead users are encouraged to use SMTP to dispatch emails from WordPress.

In a brief summary, the following are the two main reasons why WordPress is not sending your email:

  • You have not configured your SMTP server properly – In most instances, WordPress fails to send emails because the SMTP server on your underlying operating system isn’t configured properly.

    So what does proper configuration entail? It involves utilizing authentication, following the appropriate practices when you’re setting up the SFP records, configuring basic SMTP server settings among many others. On top of that, some internet service providers don’t allow the connection of SMTP over port 25.

    The failure of your SMTP server to connect over port 25 means that you will not be able to receive any email notifications from WordPress. If you suspect that the underlying SMTP server is not properly configured, you can use certain plugins to bypass your default server.

    Doing so gives you the utmost ability to link up with your WordPress site with an optimized delivery service that is fully managed by a third party. An example of such a third-party service would be SendPulse. The platform provides a reliable SMTP server as well as 12000 free emails per month.

  • You’re picking up poor reputation from neighbors – This is very common when you happen to be on a shared server environment. If yes, then chances are very high that your site’s underlying SMTP server is sharing Sender Reputation with hundreds if not thousands of other senders.

    The fact that you’re sharing IP space or Sender Reputation with others might be problematic for your email deliverability especially in situations when a sender on shared environment does not have good sending practices or is sending emails to purchased lists.

    The same is true if a sender on the shared environment is experiencing high bounce rates or receiving high complaint rates. You can also experience problems if the hosting provider doesn’t monitor users to combat poor senders from abusing the network.

    Finally yet importantly, you’ll experience problems if one or more senders hits some sort of spam trap or blacklist because of poor sending practices.

Of great importance to note is that being on shared servers is not necessarily a bad thing. In fact, it can go miles to help enhance your deliverability if other senders on the shared server boast a great reputation.
