Hey @escocia1 – I’ve moved this topic to the general “Support” category since Mailhog isn’t actually an Add-on and comes bundled with Local core.

The Mailhog utility in Local is pretty powerful. To be specific, any mail that is sent using PHP from the actual WordPress site will be captured. This includes emails that are sent using the [`wp_mail()`](https://developer.wordpress.org/reference/functions/wp_mail/) function, but also lower level PHP functions to send mail.

I’m not 100% sure if Mailhog will capture emails from plugins that replace WordPress’ default mailing function and instead make API calls to their service.

Some example plugins that come to mind are for [Mailgun](https://wordpress.org/plugins/mailgun/) or [Sendgrid](https://wordpress.org/plugins/wp-sendgrid-mailer/). If you are using some custom emailing plugins, you might want to keep that in mind!
