Fill the gaps in your customer database by appending verified email addresses to your existing records.
What Is Email Append?
Email append takes the customer records you already have — names, business names, phone numbers, mailing addresses — and matches them against our databases to fill in the missing email addresses.
So if you’ve got a stack of customer records with names and addresses but no emails, we can fill in the gaps instead of making you start over.
