Frequently Asked Questions

How does Email Appending work?

We take the names, companies, and postal details from your file, match them against permission-based master databases, and return verified addresses with the source and date stamped for every match.

Is appending CAN-SPAM and GDPR safe?

Matches draw only from opted-in and business-context sources, and we provide documentation supporting lawful basis so your ESP and legal team stay comfortable.

What if an appended email bounces?

Delivered files are guaranteed under 1.4% bounce; any excess is replaced free on your next cycle, no dispute needed.

Should I email appended contacts immediately?

Best practice is a short permission-pass message first; our team supplies recommended welcome-back templates with every order.
