What Is Email Appending?

The word “append” simply means “to add or supplement”. Therefore, email appending simply means adding emails.  The email address is obtained by matching those records from the your database against our network of data to produce a corresponding email address. We keep the process simple and provide you only with email addresses that you didn't have and that you can use. 

Send us your data file so we can assess your needs and we'll append as many validated email address to your file and return it. You can append more than just email, adding fields such as age, income, marital status, etc. Basically, an append transforms your database from a list of contacts to a list of real people.

Reverse Email Append

Not to be confused with a regular email append, reverse email append involves using your current customer email address and matching it against a data provider’s database (like) to obtain full names, postal addresses, phone numbers and other important information of your customers. So, it’s essentially opposite of an email append.

A Clear Picture of Your Customers

Think of your current database as a rough sketch of your customer. The outlines might be there, but it’s really hard to tell what this person (or business) actually looks like. When you append more data, you add more detail to the sketch, until it becomes a real portrait. In the end, appending your data just means making your list more thorough and accurate.

Enhancing your data with an append makes your campaigns more effective. Not only are you better able to reach your customers, but you have greater insight into who they are, which will make your messages more relevant. It’s all about turning that stick figure sketch of your customer into a persona you can truly understand.
