Is WordPress not sending emails properly? No worries, this is a common issue that’s easy to fix!

In this article, we will teach you how to fix the problem, and will also provide a step-by-step guide on how to configure the SMTP email service in your WordPress site using a third-party plugin.

In addition to that, but we will also give you the option to secure your email deliverance using both Hostinger email service and Mailgun automation server.

Identifying the Issue

Before we get to the bottom of this problem, let’s clear one thing up first.

WordPress not sending emails has nothing to do with your hosting provider.

While a hosting service does have a lot of power over your website, sending your emails via the WordPress email function is a completely different story.

The fault of WordPress not sending emails most likely lies in the PHP mail function configuration on your WordPress installation. The native WordPress email function requires to be set up manually with the help of a third-party plugin.

Now, before you shift the blame to the poor WordPress, hear us out first.

Despite having an email feature, WordPress is not a good option to do that particular task from the get-go. Even if it’s working, emails sent from WordPress sites tend to fail the spam test conducted by both hosting providers and email services.

That’s why they usually end up getting blocked or thrown into the spam folder.

Luckily for you, it’s still possible to ensure your email deliverance despite being sent from a WordPress site. Instead of merely using WordPress’ native email service, you can configure a Simple Mail Transfer Protocol (SMTP) server in it.

This step is essential as it will guarantee your emails’ deliverability with its authentication feature. That way, your emails will finally have the proper authentication needed to bypass spam tests and firewalls.

SMTP servers will also help you to manage the outflow of your email traffic, thus allowing you to send out a bulk of emails at once.

Configuring Mailgun SMTP As Your Email Service

The previous tutorials prove that you can send emails from either the WordPress email service or your web hosting SMTP support. However, there’s another method where you use an external SMTP service to do the job.

Reliable

In most cases, hosting providers and email services are equipped with an antivirus and spam test. Emails originated from WordPress sites usually cannot go past those filters. The use of an external SMTP service will easily remove this hindrance as they have an authenticated reputation that could bypass most spam detections.

Minimal effort

If you’re using VPS hosting, there’s no need to set up and maintain a server. The need to purchase and maintain your own hardware is also removed from your worry list.

Efficient

External SMTP services’ best features include a robust spam filtering that could redirect spam emails to a quarantine folder. This measurement prevents them from clogging your inbox and, most importantly, bandwidth.

Dedicated storage space

This feature is particularly essential if you’re managing a business email that gets a constant flow of emails per day.

Secure webmail access

Aside from the spam filtering, external SMTP services also have advanced security protocol. This feature ensures an encrypted connection from the moment you sign in until the time you sign out.

As one of the best email automation services in the market, Mailgun poses as a strong candidate for your email deliverance facilitator.

Mailgun provides a cloud-based email service for sending, receiving, and tracking emails sent through your site. The free plan allows you to send up to 10,000 emails per month or 100 emails per hour.

Once you feel this number doesn’t suffice, you can upgrade your plan to increase those limits and get additional perks that the free plan doesn’t get.

Mailgun Registration Page2. After completing the signup process, there are still a couple of verification steps to complete. Follow the onboarding process and you should be good to go in no time.

Conclusion

WordPress is one of the best Content Management System on the market. Despite their nature and popularity, WordPress is unable to excel in the email deliverance area.

If you encounter any issues related to WordPress not sending emails, the source of the problem most likely lies in its’ PHP mail function configuration.

Another thing that might disturb your email traffic sent from WordPress sites is the spam test conducted by the recipient’s hosting providers and email services. This is due to the fact that native WordPress emails don’t have the proper authentication to bypass those security measurements.

For these reasons, we don’t recommend using the native WordPress email function to send emails.

Instead, you can make use of other free external SMTP services. WordPress has a selection of plugins like WP Mail SMTP that could enhance your email deliverability.

Several hosting providers like Hostinger also equip their hosting plan with an SMTP protocol that you can take advantage of.

The last option is to use independent email automation services such as Mailgun and Google SMTP server.

Either way, we encourage you to prioritize the security and deliverability of your emails by configuring an SMTP protocol in your WordPress.
