There are organizations called blacklists like Spamhaus as well as other filtering organizations like Cloudmark and Brightmail. Email clients like Yahoo and Gmail and Hotmail rely on them to help block spam (yay!). These blacklists leave spam traps or honeypots for shady list sellers to collect. Then, if one of those email addresses ends up in your purchased list, you're in big trouble! It's like having bad credit - it can take a long time and a lot of hard work to rebuild trust with blacklists and until you do, you'll have poor delivery results even if you've stopped using the purchased email list.
The DMA’s 2017 Response Rate Report finds that the response rate for mail sent to people on house lists (subscribers who opted in to mail) was 5.1% for the year, and the response rate for prospect lists (potential clients) was 2.9%. These numbers are up from 2003, when house lists drew a response of 4.4% and prospect lists a response of 2.1%. And even though online shopping has surpassed purchases from direct mail pieces, the DMA reports that 100.7 million U.S. adults made a purchase from a catalog in 2016, compared with 209.6 million people who made purchases online the same year, per Statista.
Hey Jonathan , enjoyed the article but it’s far fetched for startups and beginners like me who came here to see how in the first place we bring people to our website and not how we engage them or get email out of people who are already there.. getting people on your website is a bigger challenge, love your knowledge about the field is there an article which will help solve this?
