USA consumer email lists

 A Few Notes about List Quality

As you grow your email marketing list, know that the list will go through natural attrition, and contacts will change or become obsolete.
How do you measure the quality of the new contacts you've added to your list? Tracking and measuring the open and click-through rates are of course two key metrics to track the 'engagement' level with your contact. However, you should also compare the following metrics to your existing USA consumer email lists:
• Hard Bounce Rate - Up to 3% of B2B contacts change every month, so even database that has been completely updated every quarter will see over 8% of your contact list become 'obsolete' or dead as a result of hard bounces.

• SPAM Reports - When a recipient believes your email is SPAM and clicks the 'Report SPAM' button, a flag is raised and the delivering ISP will start to monitor your future mailing s to see if they are SPAM. Even with 100% double-opt-in emails you can expect complaints in the range of 1 per 1,000 emails sent to 1 in 5,000 email messages sent to be reported as SPAM. This can also happen automatically if for some reason you repeatedly send emails to a non-working email address. If your Email Service Provider (ESP) is reporting a higher complaint rate than one per 1,000 - it's time to seriously re-evaluate your email marketing message, targeting and send frequency.
