You already know these people. Now you can email them.

Your customer data holds people who buy from you, give to you, and open your mail — but if the email column is empty, your least expensive channel can't reach them. Renting someone else's list doesn't fix that. It just puts your message in front of strangers.

Why append instead of rent

Email append works from the relationships you already have. We take your names and postal addresses and match them to email addresses, for consumer or business records. The people are the same people — your customers, your donors — you just gain a faster, cheaper way to reach them. That's the difference between growing your email program and borrowing someone else's.

There's a right way to do it. Email is a permission channel, and appended addresses deserve a careful introduction: a first message that says who you are, why you're writing, and how to opt out — sent before any promotion, and ramped in gradually so your sender reputation stays healthy. That welcome pass is yours to send, from your own platform; we'll talk through the approach with you, because an append that hurts your deliverability isn't worth running.

And every address we append is fully validated before it reaches you — so you're starting from deliverable addresses, not a fresh pile of bounces.

What you get back

Your data returns with the original records intact and matched email addresses appended, coded record by record so you can see exactly which customers gained an address. Turnaround is a matter of days. And because the results are documented, your master data improves — not just one campaign.

We'll tell you if this isn't the move

Email append isn't right for every situation, and we'll say so when it isn't. Since 1994 we've started every project with a conversation: what you're trying to do, what your data can support, and what you don't need to buy. A real person looks at it with you — and stays reachable after the job runs.

How it works

1. 1

   Start with a conversation

   We'll ask how the email addresses will be used and what your current data looks like. Email works differently from mail — matching a person is only half the job; reaching the inbox responsibly is the other half — and we'll walk through both before anything runs.

2. 2

   We match your records

   Your names and addresses are matched to email addresses, for consumer or business records — the people are ones you already have a relationship with, which is what makes appending them different from renting a list.

3. 3

   Everything comes back documented

   Your original records return intact with the matched email addresses appended, coded so you can see exactly which customers gained an address. Turnaround is a matter of days, not weeks.
