We used to email thousands of people a day, but got into issues; firstly, our domain got blocked by all major Email providers. Our entire organisation couldn’t send emails to anyone. Even worse fear, I know of several start-up who went bankrupt by facing massive fines due to not complying with GDPR; they were using automation tools to send mass emails to hundreds or sometimes thousands of people a day.  I have experience with Apollo, Zoominfo, and Cognisim, yet the vast majority of the contacts I get are not suitable for me. It's essential for me to be very precise and only reach out to the target ICP.  I do not want to spam people again. I want to do proper “sales” and “marketing” this time. But working on smaller subset of people but paying more attention to them. Rather than just casting a wide net and playing “a number’s game”. I would much rather have a tool that can get me 100 highly targeted leads than having to remove names from lists containing thousands of people, which is what I get having tried all the tools available right now.
