B2B Social Media Marketing Review from John Nicolosi
I was sent a thorough campaign questionnaire after registering that outlined the purpose of the project and my target audience. LeadBuds took those responses, created some brilliant message sequences, and created a LinkedIn prospect list that was specifically targeted. I made dozens of new connections and had six survey replies in the first two weeks of the campaign. These are lengthy questionnaires with in-depth inquiries. I've already had six answers, compared to my estimated 1-2. They know what they're doing based on the outcomes they provide, therefore I won't recommend changing. Continue as you are!
