Data appending
Contact data appending queries the RampedUp database by email address and returns the most recent publicly available data about that individual — up to 60 fields per record. It also flags outdated records and updates them with the new employer.
Available in the user interface and through the API. You send what you have; you get back what was missing, plus an honest report on what could not be matched.
What appending does to a contact record
Standardisation
Standard industry, title, department and level — so your segments mean the same thing across every record, not just the ones a rep typed carefully.
Enrichment
Up to 60 fields of data to fill in the white space around a name and an address.
Deduplication
The same person often sits in your database under two or three email addresses. Appending resolves them to one person.
Digital advertising
Fields shaped to be accepted by the ad platforms — Facebook, LinkedIn and Google — so a CRM segment can become an audience.
Company appending runs a waterfall
Matched in this order, strongest identifier first.
Company RUID
The RampedUp identifier, where you already hold one.
LinkedIn company URL
An unambiguous public handle for the entity.
Company website — exact match
The full URL as held.
Company root domain
Falling back from the exact URL to the root.
Email domain
Derived from a contact address on the record.
Other company website
Alternate or historical domains — see web identity.
Company name, filtered by location
The weakest key, used last and constrained by location details to avoid false positives.

Match rate on your own file depends on what you send and how aged it is. Send a sample and you get the real number back before committing — typical list turnaround is 24 hours, or roughly one second per contact record.
Start with the number.
Tell us the segment you actually sell to and we will send the exact count, the fill rates for that slice, and a sample — before anyone asks you for a budget.
