I use Hubspot for my email marketing. I recently got a bad list of leads by mistake, the company sent a list of unscrubbed emails which caused me to have a very high bounce rate when I emailed the list. Because of this one email my domain reputation has tanked and now all my emails go to spam or aren't delivered. I've tried to do what Hubspot suggested by slowly building it back up and only sending to people who have opened my email in the past two weeks but it has been almost 6 weeks of this and it doesn't seem to be helping.
Does anyone know any remedy to get your domain reputation back up or can tell me what I need to do? Anything is very much appreciated.
