If I could I would give HubSpot a negative 5 star! We unfortunately were suspended for a high hard bounce rate due to an unclean list. However, it has been 3 weeks now and HubSpot support is STILL making us jump through hoops! I have removed the bad contacts and uploaded a Opt-Out list and emailed tech support 3 times! This is insane. Their customer service SUCK! If you do happen to be allowed to speak to someone on the phone they literally can't answer vital questions. Do yourself a favor and DON'T use Hubspot! They are horrible!
