8 Best WordPress SMTP Plugins For Your Email Campaign

If you are running a WordPress site, you should make sure that your emails get delivered. But the problem is that the default WordPress mailing option often fails to deliver emails reliably. Your messages can frequently end up in the spam, or even worse, they might not arrive at all.

That’s why using a WordPress SMTP plugin can come in help! SMTP stands for Simple Mail Transfer Protocol, basically replaces WordPress’s default with a more secure and reliable service. This ensures that your emails are more likely to reach where they are supposed to land.

Here, we have listed the best WordPress SMTP plugins, compared their features, and also provided you the tips for choosing the right SMTP plugin for your WordPress site.

Why do you need a WordPress SMTP plugin on your website?

Take this as a situation where you have put a lot of effort into customizing your WordPress emails. The design looks great and every detail is carrfully thought. But the email wasn’t sent to your audience or ended up in their spam folder.

Frustrating, right? That’s because the PHP mail() function that WordPress uses to send email often leads to deliverability issues. An SMTP plugin solves these issues in the following ways:

👉 Ensuring email deliverability: Your emails actually reach inboxes, not spam folders.

👉 Improving security: Authentication methods like OAuth prevent unauthorized email usage.

👉 Providing logging and tracking: Helps debug issues when emails don’t send properly.

👉 Allowing integration with external mail servers: Services like Gmail, Outlook, or SendGrid handle your emails more efficiently.
