Best ROI Lists can provide you with up-to-date voter files from around the nation. Registered voter lists are updated at different intervals throughout the year and can help you enhance any political initiative or lead generation campaign. Best ROI Lists can append the voter files or any postal consumer files with voter history, email addresses, sms numbers, household income, religion, or hundreds of other psychographic fields of data.

Best ROI Lists’s data appending service is a multi-staged process by which we match records and then send an opt-in message. In the end, you are delivered a fully opted-in list that you can use again and again…because you own the data!

What is appending?

Data Appending

Match. Scrub. Power up your database!

Best ROI Lists’s data appending service accurately match usable, deliverable email addresses, postal addressees or sms mobile cell phone numbers to your existing customer database.

Who owns the names once the append is done?

You do.

You only pay for useable, deliverable email, postal or sms addresses/numbers — and once the process is complete you own the new data!

What are the benefits of email appending your customer database?

Cut costs & Increase Response.

  • Data Appending rapidly and cost-effectively expands your reach and lowers your cost per contact.
  • By communicating with your customers in a multi-channel environment, you’ll reinforce your message and can improve response rates by as much as 60%.

What is the process involved in email appending?

We match. We send. You gain a whole new level of ROI on your database.

  • Your customer database is matched to the Best ROI Lists database of 200 million names. Whenever a match is found it is flagged.
  • A comprehensive Welcome Program is embarked upon over a 3-week time frame, in which email, post card or text messages are sent to the new database of flagged records. All undeliverables and unsubscribes are scrubbed.
  • Once the file is determined to be usable and deliverable your append is complete.
