Preventing Deliverability Issues Caused by Transactional Emails

If you chose to send all the emails from your website using the MailPoet's sending method and you're sending your emails with the MailPoet Sending Service, you should be aware that our Anti-Spam banning policy will be applied to all of these emails, as they will be processed by our system.

As it's harder to monitor every email sent from your website and any possible issues they may cause, it's possible that your reputation is affected without you knowing exactly where the problem is coming from.

In this article, we want to share some tips on which settings you should be paying attention to when sending your transactional emails with our sending service, and how to prevent them from becoming potential deliverability issues.

Spammy comments

Blacklisted URLs can be coming from spammy comments or from any other contact form you have on your website.

You can check if you have too many comments on your website marked as Spam. Sometimes spammy comments add blacklisted domains as their names, so the notification emails sent through our servers contain these URLs. Spammy URLs are usually related to making profits, bets, and illegal services.

Check the WordPress Settings > Discussion if you have selected to send an email to the admin whenever anyone posts a comment and/or a comment is held for moderation:

Protecting 3rd-party forms

If you have other forms on your website, ensure they are all protected by adding a captcha. This includes contact forms and subscription forms from 3rd-party plugins.

Contact forms attract a lot of spambots. A spambot is a malicious program or unethical activity specially designed to gather email addresses or information from contact forms. It is usually done by sending spam emails.

It will not only create false traffic but also results in malicious attacks on websites.

Some guides on how to protect popular 3rd-party form plugins:


Notifications and alerts

You may have enabled notification settings from the MailPoet plugin or any other 3rd-party plugin on your WordPress website, and all of these emails are considered transactional emails. MailPoet allows you to enable "New Subscriber Notifications" and "Stats Notifications", for example. Other plugins, such as WordFence, allows you to set up an email address to receive alert notifications.

It could be that when setting up a plugin for the first time, you or someone else responsible for your website has set up a fake email address (i.e.: test@test.com) or an old email address that is no longer available at the moment, and these notifications are still being sent to these addresses. This means that all of these emails will bounce back and affect your reputation as a sender.

If you're not sure where to check for these settings, you can search for "notification email" in your 3rd-party plugin's documentation and also check our article on places to search for a specific email address.


WordPress and WooCommerce fake signups

To avoid fake signups, we strongly recommend adding reCaptcha to the WooCommerce registration form: https://woocommerce.com/document/recaptcha-for-woocommerce
