Our EMEA team is working with an agency to purchase lists of German leads to invite them to our marketing events in Germany.
I am very wary of this because of the strict anti-spam laws since many of these leads have no prior business relationship with our company. I have advised against list purchases, but it's not up to me to give the final say.
I already have an approach for getting double opt-in from leads already in our database, but this is a separate case since we have no prior relationship with these list build leads. There seems to be very little information available online and most of it is in German.
Interested to see if anybody has faced a similar situation and how you would go about contacting list purchased leads.
