wordpress, web, design

Sending and resending emails is a crucial part of running any WordPress website. Whether you need to send account registration emails, e-commerce order confirmations, or newsletter campaigns, having a reliable email setup ensures your vital communications reach your subscribers' inboxes.

However, the default WordPress email functionality has limitations that can hinder email deliverability and open rates. This is where a dedicated WordPress mail plugin becomes essential.

We'll cover everything you need to know in this blog. Keep reading to learn about crucial WordPress tips.

Understanding WordPress Email Functionality

Before we dive into WordPress email plugins, it's important to understand how WordPress handles sending emails out of the box.

Default WordPress email settings 

When you first install WordPress, it comes preconfigured for sending or resending emails using the PHP mail() function.

Specifically, WordPress uses the wp_mail() function to handle all outbound emails ranging from password reset emails to email subscriptions.

wp_mail() function 

The function takes your content, formats it into a proper email message, and hands it off to the server's native function for delivery.

Normally, WordPress, by default, sends emails through your web hosting site's basic SMTP settings. Usually, shared hosting services have simple SMTP servers made for small personal activities instead of large transactional and list emailing needs.

Limitations of default email settings 

Relying on your basic shared web hosting SMTP server can cause the following problems:

  • Poor email deliverability: Emails may get trapped in spam or not arrive at all.

  • Lack of customization: You have limited control over names, email formatting, etc.

  • Difficulty with mass mailing: Shared SMTP servers often throttle emails to a few hundred per hour.

  • No delivery guarantees: The wp_mail() function doesn't validate successful delivery.

  • No analytics or insights: You can't view rich stats like opens, clicks, etc.

  • Security and compliance risks: The basic SMTP servers lack important email security protections.

Why you need a WordPress mail plugin 

WordPress, blog, blogger

To overcome the limitations above, it is crucial to install a dedicated WordPress mail plugin connected to a professional third-party delivery service.

Here are some key benefits provided by WordPress email plugins:

Improved email deliverability 

Professional email services like SendGrid, Mailgun, and Mailchimp have advanced deliverability features like IP warming, domain authentication, and sender reputation monitoring, which massively improve the chances your emails reach the inbox.

Enhanced email customization options 

Email plugins give you more control over critical details like your sender name, email formatting, and more to polished, professional communications.

Integration with third-party email services

Assessing your website's email requirements 

website, computer, online

First, consider your specific email needs in areas like:

Email volume 

If you have multiple email addresses and send low volumes of email from each, a free plugin may suffice. High-volume mailers will require a premium plugin or third-party service.

Email types (transactional, marketing, etc.) 

Assess whether you need to send marketing emails, transactional notifications, automated messages, or a combination.

Email customization needs 

To choose a sufficiently robust plugin, consider how much customization you need for emails, such as branding, templates, targeting, etc.

Compatibility with your WordPress theme and plugins 

Ensure any plugins you are considering are compatible with your WordPress version, theme, and other installed plugins to avoid conflicts.

Ease of use and setup 

When choosing a plugin that your team can comfortably use, evaluate the setup process, interface, and available support.

Considering third-party email service integrations
