“I was in need of adding mobile phone numbers to my email list for about 100K records for a fundraising campaign. Our data was a few years old so it was pretty stale, luckily, Accurate Append was able to fill in the gaps and provide updated contact data. This helped our campaign significantly! We were able to achieve better ROI because of their services - we highly recommend!”

Contact Data Appending
One of our core services is appending missing contact information to your existing customer records. Many businesses run into issues when they lack accurate phone numbers, email addresses, or mailing addresses for their customers. This can hinder effective multi-channel marketing campaigns. We solve this by appending the missing data, ensuring your customer records are complete and up-to-date, so you can reach your audience more effectively.

This allows you to enhance your existing records with valuable insights, such as demographics, wealth indicators, and donation history. For example, if you’re a nonprofit organization, our enrichment services help you prioritize high-potential donors by adding key data points like donation history and wealth insights, enabling more personalized and effective outreach.

Lead List Building
In addition to enriching existing records, we can help you build new lead lists from scratch. Using our database of over 250 million US consumers, we create custom lead lists that align with your campaign goals. If you’re in real estate or financial services and want to target a specific group, such as affluent individuals or first-time home buyers, we can filter by wealth, demographics, or other criteria to deliver a qualified list of leads, giving your team an edge in finding new customers.
