Accurate Append Gives You Options

Accurate Append's automated Phone, Email, and Demographic Append and Verify solutions can be engaged in two distinct ways – either by simply sending us your contacts file (the "Batch" method), or by integrating your applications directly through our software library ("API" for developers).

Batch is the simplest option, and the best choice for most busy sales and marketing professionals – it means you just send us your contact file, we process it and send it back.

For software developers, the API is a great choice when you need fine-grained control of contact data processes or real time integration with your applications. Unlike Batch, you don't send a file of contacts, you send HTTP GET requests to look up data for a single contact at a time.

Either option can dramatically bolster the accuracy, completeness, and value of your contact lists.

How you choose to send us your data, and the level of automation you want, is up to you.
