Do we have people here using hubspot for cold emailing??

Hello guys! I just tried to sign up for hubspot free trial, open ratio seems to be really good, 40% after 10 minutes of sending emails. I just sent about 60 for a test.

The problem is, if i continue sending in bigger quantities daily, won't they block me? As I understood - they dont allow to send emails to not obt-in data, or am i wrong? Because they really get emails inboxed, it seems..

Need more opinions/experiences on this!

Guess you're using the starter package, which cost $50 , they will ban your account after several spam complaints . also you have a nice list with 40% open rate and with the right niche you should do your own setup. (dedicated server + few domains/multiple IP's ....) warm and start blasting.
if the list even bigger contact getresponse for their service getresponse360 , the cost is about 3k per month but the inbox rate is awesome and they really don't care about the source of the email (just buy an old domain setup an optin plugin and tell them its from there)

Hey do we have more people who are using or used hubspot for cold emailing?
