I have got tested and verified email list of 5 Million ( Negligible bounce rate as I use to remove hard bounces and unsubscribes regularly).
The list is highly active and more than 10% open rate is there on any email campaign.
Contact me if anyone would like to buy it.
I don't want to invest money in creating a product yet, is it better to build a email list and email the list every once in a while till I know I could make money? Is there other ways to test if the product will convert well, before committing to creating the product?
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like firstname.lastname@example.org.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
