We were mostly relying on meetings secured from cold emailing. However, we were often getting invalid emails from all the tools we used or 3rd parties we outsourced them from. If we had quality emails, another obstacle was the bounce rate. If the email went through the soam protection then the prospect had to open the email, read and eventually reply. Too many factors that were hard to influence.
We used LinkedIn very little, basically only to look up the people from companies and then use that information to generate emails for cold-email campaigns.
Nevertheless, the biggest issue was that we didn’t have any means how to push the deal from the initial meeting to the finish line.
