8 Best WordPress SMTP plugins for your email campaign

Email deliverability is a critical aspect of any WordPress website. However, the default WordPress mail function often fails to deliver emails reliably, leading to messages landing in spam folders—or worse, never arriving at all.

That’s where WordPress SMTP plugins come in. These SMTP (full formed as, Simple Mail Transfer Protocol) plugins replace WordPress’s default mailing system with a secure and reliable SMTP service, ensuring your emails reach the intended recipients.

In this guide, we’ll break down what to look for in an SMTP plugin, go over the best options out there, and compare their features.

• Multiple SMTP provider support: Should allow integration with various services like Gmail, SendGrid, Mailgun, etc.

• Authentication methods: Secure login via OAuth, API keys, or traditional SMTP login.
• Backup mailer options: In case the primary SMTP fails.
• Enkel användning: A simple setup wizard is always a plus.

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

By default, WordPress uses the PHP mail() function to send emails, which often leads to deliverability issues. An SMTP plugin solves these problems by:

👉 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.

Sammanfattningsvis

Picking the right SMTP plugin for your WordPress site really comes down to what you need. No matter which one you go with, having an SMTP plugin is a must if you want better email deliverability, security, and tracking. 

A solid SMTP service helps make sure your emails actually land in inboxes—boosting communication, marketing, and overall user experience on your site.
