It\u2019s pretty frustrating when you install a WordPress plugin specifically for handling emails on your site, and the emails just won’t deliver. <\/p>\n\n\n\n

You set everything up, your customer places an order, but the confirmation email never arrives. Or a user tries to reset their password and gets no email at all.<\/p>\n\n\n\n

Customers expect an email as soon as they place an order. Just think how scammy it would seem if a customer were to place an order, the amount is charged and deducted from their account, yet there is no confirmation email.<\/p>\n\n\n\n

It can happen with many plugins, including all that send transactional emails for any reason; MailPoet is no exception.<\/p>\n\n\n\n

The good news is, the solution is pretty straightforward. With three steps, you can quickly get MailPoet back on track and ensure your customers actually receive the necessary emails. <\/p>\n\n\n\n

Before jumping right into it, let’s take a moment to understand the service.<\/p>\n\n\n\n

What is MailPoet?<\/strong><\/h2>\n\n\n\n

MailPoet is a WordPress plugin designed to send both newsletters and transactional emails, such as order confirmations, password reset links, and account notifications, directly from your WordPress dashboard. <\/p>\n\n\n\n

What makes it appealing is the simplicity. Instead of relying on third-party platforms, you can control email inside WordPress. It integrates with your existing site, allowing you to design emails with a drag-and-drop editor.<\/p>\n\n\n\n

MailPoet has two modes for sending emails. One is their dedicated service, and the other is using WordPress’ default email system. The next section will explore where the problem occurs.<\/p>\n\n\n\n

Why MailPoet Emails Fail to Send<\/strong><\/h2>\n\n\n\n

As we learned, MailPoet has two modes of sending emails. <\/p>\n\n\n\n

The first one is through their dedicated service called MailPoet Sending Service (MSS), and the other one is using the WordPress default mailer, which is the wp_mail() function. <\/p>\n\n\n\n

There can be issues with either one you choose. Here’s how.<\/p>\n\n\n\n

Using MailPoet Sending Service (MSS)<\/strong><\/h3>\n\n\n\n

MailPoet actively monitors the quality of emails being sent through its system, MSS. <\/p>\n\n\n\n

If your emails trigger too many spam complaints or generate a high number of bounces, the service may temporarily suspend your account. This is part of their anti-spam policy to ensure only high-value content reaches inboxes.<\/p>\n\n\n\n

For example, using a free email address such as Gmail or Yahoo as your \u201cFrom\u201d address can increase the likelihood of emails being flagged. <\/p>\n\n\n\n

The same applies if your content looks suspicious, includes blacklisted links, or comes from a role-based address like info@domain.com<\/strong><\/a>; in these cases, MailPoet will block or pause sending to protect overall deliverability.\u00a0<\/p>\n\n\n\n

Using WordPress’s Mail Sender<\/strong><\/h3>\n\n\n\n

However, if you go with the WordPress default mailer, authentication protocols can hinder the deliverability. <\/p>\n\n\n\n

To comply with modern email security rules, all email servers must adhere to specific security protocols that enable receiving servers to evaluate the authenticity of incoming emails. <\/p>\n\n\n\n

Here are the common security protocols that the default mailer lacks but are necessary for higher deliverability rates:<\/p>\n\n\n\n
