Email list building solution is witnessing a transition phase owing to tons of new players with low costing.
Our solution is custom implying virgin list with replacement guarantee of bad contacts plus min 95% email deliverability assurance.
Now, our focus has been in building real time lists leveraging news publications and social media triggers.
Still, I feel there is some industry expectation mismatch.
What are your expectations?
The best thing you can do for your self and your client is to be strictly sure your prospects opt in to your email list and by extension, your sales funnel themselves. To me, if you measure your ROI for the current strategies of ( just adding supposed triggers from social and news platform) and that of doing it right, getting your candidates to opt in themselves, you'll find that the later system delivers on best on conversion.
So I think rather than adding tons of email to your list from any source, dissipating energy on providing value to clients that help you earn their opt in is way the best approach. Not doing this is one industry mismatch in itself.
My expectations are:
1) I own the contacts
2) You can't sell the contacts to anyone else
3) They were all legitimately obtained and comply with CAN-SPAM and GPDR regulations
4) They're relevant to my product/service
Low cost is a reflection of illegitimate contacts being sold and resold and obtained through illegal practices. Don't be that guy.
