Hi @jrotem,
Thanks for reaching out!
Whenever your website executes the wp_mail() function, it will count that as an email notification.
These emails could be,
– WordPress user registration emails
– WordPress reset password emails
– Form email notifications (for example contact forms, quotation forms, payment forms created using WPForms plugin, Contact Form 7, Gravity Forms, or using similar plugins)
– Order notification emails (if you have an eCommerce store set up on your site)
– WordPress comment management emails (comment moderation / comment published)
– WordPress plugin notifications (Eg: update notifications etc)
In most cases, you may have installed the plugin earlier and configured a mailer at a later date. So, it will count those events but you may not receive those notifications.
I hope this helps. Thanks!
