Does Postalytics check for duplicate records?

We do! The deduping process looks at all of the name & address fields, including company, and removes any with an exact match. 

Here’s an example of a duplicate match – one of these will be removed from the mailing:

1. Record 1: John Smith, My Company USA, 1234 Main St, Anytown MA 02370
2. Record 2: John Smith, My Company USA, 1234 Main St, Anytown MA 02370

Here’s an example of a non-match – both of these will remain in the mailing: 

1. Record 1: John Smith, My Company USA, 1234 Main St, Anytown MA 02370
2. Record 2: Jon Smith, My Company, 1234 Main St, Anytown MA 02370
