# Import contacts

To import contacts into your Marketing section you have to prepare a .CSV document. To prepare a .CSV document one must open spreadsheet document (Example: Excel), where you type in all your contacts and their details. Each information about the contact must be written in its own column. Certain personalized information about your contacts will have to be added to your marketing section as new attributes and those have to be prepared in advance.
To prepare customer’s attributes, please read Attributes in the Marketing section or see the tutorial.

Import table example


Each contact in your .csv file should contain at least one unique identifier. Identifiers that are checked by the system are ID numbers, CODES, and Email addresses.

  • During your first import, an ID number will be automatically assigned to each imported contact. After that, you can use that same ID number for any updates.
  • CODE can be assigned to contacts either manually or automatically.
  • DEFAULT EMAIL address is the third and the most common identifier which is assigned to each contact manually.

After the import, you can see the ID number and code by clicking the View button in your contacts list.

We recommend you prepare a file with all the contact information before your first import. If you decide to prepare import files with codes and emails, make sure each contact is assigned a unique code that is only used once. If you decide to only use emails, then all the codes and IDs will be assigned to contacts automatically.

Each time contacts are imported they will overwrite existing contacts that have an identical unique identifier as an existing contact. Example: If your contacts list already includes a contact with CODE number 101, and you prepare a new import file that also contains CODE number 101, then the latest import will override the already existing one. This way you can lose already existing contacts.

Our advice is to import contacts with Codes and emails and let the system automatically assign ID numbers to them. Once your number of contacts grows, you can always export them, arrange them by identifiers (either codes or IDs) and edit them or add new ones and then import them back.

# Importing contacts with multiple contact details

When importing contacts with multiple contact information of the same type (Example: contact with more than one email address), you must first import those contacts with only one contact information of the same type. After contacts are imported, you can manually add the other information of the same type.
If you wish to import more contact info with the importer, then you must identify the contact by the code and add the new contact info in the .csv file. The system will add the contact info to the existing one.

# Importing contacts with addresses

When it comes to importing contacts with addresses, make sure you put each info in a separate column and ALWAYS add all the required info: FIRST NAME, LAST NAME, EMAIL, STREET, STREET/HOUSE NUMBER, POSTAL CODE, CITY/TOWN, AND COUNTRY. Without all this information the import will fail.

To create an import document (CSV) with ease, we have prepared a table of content you can import when adding contacts to DG1 marketing to facilitate the process of importing contacts.

Import Contacts

  1. Enter details about the import:

Import Contacts

  • Name: Name of your new import.
  • Segment: Add contacts into a segment. Segment is a group of contacts that can be added with Import or by filters. You can import all contacts to one segment directly or you can filter them through a variety of characteristics. Example: Let’s say you had a prize game and you would now like to import contacts to your database. It’s recommended that you create a segment called Prize game rather than creating a new mailing list. Segmenting your contacts will really help you because you will be able to use the same contacts for different purposes and promotions. It’s better to have only a few mailing lists and more segments within mailing lists.


Choosing a segment is not mandatory! You have to add contacts to Mailing lists, at least the default one!

For more information on how to create a new Segment see DG1 Targeting manual.

  • Country code: Choose a country calling code if all your contacts in .csv file have the same country calling number. This way you do not have to manually add country calling codes to your .csv file. If you have international contacts list in the .csv file, it has to contain a column with all country calling codes.
  • Subscribe contacts to refers to “one to one” communication with your contacts outside mailing lists. Recommendation: leave them as they are.
  • Choose the mailing list to which you want to import contacts. Click in the window and choose your mailing list or leave it set to Default.

If you already had headers in your import file, the selection will be done automatically but it might not recognize all headers. So follow the above instructions. If your import document does not include headers, you will have to add them manually.
Example: Import did not recognize certain headers and you will have to manually add them by clicking the arrow and choosing the right one.
