Need to add missing pieces of information to your database? Our data appending service is the answer.

If you are planning marketing activity but missing vital pieces of information such as contacts name, address or email address, then Data Appending is the service for you. We specialize in providing you with up-to-date and accurate data for your campaigns through email address appending and data verification.

Data appending is a service where we match your contact database against our multiple sources of information and fill in missing gaps. For example, you may have names and phone numbers, but won’t have postal addresses for your contacts. That’s where we can help.

The process is simple:

  1. Send us your list of postal addresses and names. These can be B2B or B2C.
  2. We will clean and standardize your data ready for matching using USPS CASS certification. This produces higher match rates.
  3. We then match this data against national postal and email files containing hundreds of millions of records.
  4. We find matches.
  5. We then send your data through the Permission Pass Opt-in confirmation process which confirms deliverability of the email addresses.
  6. Opt-outs are taken off the file and hard and soft bounces are removed.
    We add the emails to your list and deliver back to you.

B2B Data Appending

Typical match rates are 35% to 65%

B2C Data Appending

Typical match rates are 15% to 20%.

Transform your data

Data appending is so powerful. It can transform an inaccurate old legacy database, missing vital information and tired after years of neglect, into a powerful tool for multi-channel marketing. It is cheaper and more efficient than trying to cleanse and populate the data yourself.
