Show which contacts did not receive emails

Can Hubspot please create a function where I can immediately determine which contacts in my recipients list did not receive an email sent, and why?

This would be especially useful when the emails are of a transactional nature, or for events that the recipients already registered for and need further details to attend.
And yes, I have set all contacts as Marketing Contacts.

Hi @Gwenne

There already is a “not sent” category in the recipients tab in HubSpot’s E-Mail Tool.

You can filter by various reasons why the contact wasn’t sent an email, along with the option to create a new list, add to an existing one or export those contacts.

Is that what you were after?

Thanks
