Email Appending
Establish email communication with customers for increased ROI
Overview
We can add email addresses to lists that contain names and mailing addresses — and add names and mailing addresses to lists that contain only email addresses.
You only pay for email addresses that are successfully appended, deliverable, and received an opt-out message without unsubscribing.
How the process works
- 01
Permission-based match
Your file is matched against our permission-based email databases. The address returned belongs to the contact on your file — not a random colleague at the same company.
- 02
Domain pattern matching
We identify each company’s email domain, then use reference databases to find its naming convention (e.g. firstname.lastname@ or firstname@) and output your contact’s address.
- 03
Welcome & opt-out email
Once processing is complete, a welcome email introduces online communication from you and gives each contact the chance to opt out.
- 04
Enhanced file returned
Your enriched file comes back ready for multi-channel marketing — so you can start increasing results immediately.

Frequently asked questions
What do I need to send you?
A file with at least first name, last name and company or postal address. The more fields you include — job title, city, website — the higher the match rate we can achieve.
How is my data protected?
Files are exchanged over encrypted transfer, processed in-house (no middleman) and deleted after delivery on request. We never resell or reuse client files.
What happens to contacts who opt out?
Anyone who opts out after the welcome email is removed from the delivered file and flagged, so you only receive addresses that are cleared for your communication.
