We look at the following criteria when deciding to merge contacts:
- Contact name
- Company name
- Email address
- First line of address
For example we will look at both first name and last name together - so if you have two Jackie Smiths - this will then look at the other criteria such as 'company name', 'email address' and 'first line of address' to see if there is a match - if there is a match against one or more of these additional criteria then it will merge the records together as it is seen as a duplicate.
