MailPoet Sending Service Anti-Spam Policy

If you're sending with the MailPoet Sending Service you receive a significant number of invalid email addresses or spam complaints, our service will be paused for your account.

This is to ensure that major anti-spam laws are followed and you (and us) do not suffer the consequences of non-compliance. We work hard to offer a reliable and great sending service for all our users.

It takes an unusual number of hard bounces and spam complaints from the same sending or from a certain period of time for us to consider it a problem.

We send a warning email if we detect you're sending to too many bad addresses or get too many complaints - but not enough to pause your sending. This way, you can take action and prevent the sending from being paused.

If we continue to detect bad addresses and complaints from your account, you'll receive another email notification about it. Then you're welcome to contact us so we can review your account and understand what happened. In most cases, our Support Team will help you identify the issue, get it fixed, and then restore the sending for you.

In case we decide to not restore the MailPoet Sending Service for your account, you can still use the plugin and all the Premium features, and continue to send your emails via third-party sending method.

You won't lose access to your MailPoet account or to the plugin's data from your website. 

Please note that managing your subscriber's list is your responsibility as a sender and we offer many guides and features to help you with that.

You can also refer to our Anti-Spam Policy page to read about prohibited content and spamming practices.

Spam Complaints

This is the rate of formal complaints, which means how many subscribers manually flagged your messages as "Spam" or "Junk".

It could mean you're sending to people without their consent, sending emails too often or content your subscribers didn't subscribe to.

Complaints considerably hurt your reputation as a sender, but also affect MailPoet's own reputation and can make a big impact on our global deliverability, affecting all users.

Unsubscribed subscribers and hard bounces are NOT counted as spam complaints.
Read all about spam complaints here.

Hard Bounces

The hard bounce rate is the percentage of emails you send that are sent to inactive mailboxes or addresses that no longer exist. 

This can be managed by practising good list hygiene: 

Auto-response and out-of-office emails are NOT counted as hard bounces.
Read all about hard bounces here.

Transactional Emails

If you've selected the MailPoet Sending Service as the sending method to send all emails from your WordPress, we will take them into account when reviewing your account.

Some scenarios that may affect your reputation as a sender when sending the transactional emails with us:

  • You've set up an email address to receive notification emails and/or alerts from MailPoet or from any other plugin from your website and this mail address is invalid, i.e.:
    All emails sent to this address will bounce. Check the settings you have for the WordPress, or plugins such as WordFence and third-party plugins.
  • Spammers usually add blacklisted domains as their names when commenting on your website, and if you get notification about the comments, it means you will send emails linking to these blacklisted domains.

    Check the WordPress Settings if you have selected to send an email to the admin whenever anyone posts a comment and/or a comment is held for moderation:
    Discussion-Settings---jordanabina---WordPress-2020-05-01-16-27-36.pngYou should uncheck these options or go to MailPoet Settings > Advanced > Send all site's emails with... and select "the default WordPress sending method" option.
  • Some plugins, such as Ultimate GDPR plugin, create a dummy email address (, which means you'll be sending emails to an invalid email address and it will bounce. You can check how to change the settings for Ultimate GDPR here.


Ensure that your site and every other service used to send emails on your site's behalf follow best security practices.
Security issues can be difficult to detect, and their impact is not always visible, but they tend to be the number one cause of spam, phishing and malware spreading on the internet.
Even if you personally follow best email marketing practices, an unauthorized actor's bad deeds will outweigh your reputation (e.g. if they managed to impersonate your domain to send phishing emails, have hacked your site to abuse it for their nefarious purposes).

We retain the right to suspend email delivery services to your account if we have a reason to believe the site may be potentially used for abusive reasons, whether by you or unauthorized persons.
