Frequently Asked Questions
How does Email & Phone Appending work?
You upload the records you have — even just name and company — and we match them against human-verified reference data, returning work emails, direct dials, or mobiles at up to a 92% match rate, with every appended value validated through our four-gate process before it comes back to you.
Is appending compliant with CAN-SPAM and CASL?
Yes when used correctly: we screen all appends against opt-out and suppression data, and you remain responsible for honoring unsubscribe rights under CAN-SPAM, CASL in Canada, and local equivalents in your send geography.
What happens to records that cannot be matched?
They come back untouched with a report explaining why — insufficient input data, conflicting sources, or stale company references — so you can decide whether to enrich further or suppress.
How do you keep bounce rates low after an email append?
Every appended address passes syntax, domain, and live inbox verification plus a human audit, which is why post-append bounce stays under 1.0%.
