Why is a contact I deleted still receiving emails?

I removed a contact that is no longer with her company, but then received a “no longer with the company” auto response when I sent a broadcast out to a list she was formerly tagged in. Why is her email address still receiving emails from me?

@Jake_Coburn, could there have been duplicate contact records for this person?

I’ve searched first name, last name, email and company, and can’t find the contact anywhere. Not that it’s a big deal, but kind of annoying to get an auto response each time I send an email to this list.

For sure!
