In order for the import of subscribers to function smoothly, it is important that the import file is created in a correct way. Below follows instructions on how your import file should be created.
Headers - You must include headers for all columns that contain any value (demographic data) that you want to import, such as Email, Name, CountryCode and Mobile Number. Put each header in a separate column in row 1. The headers should only contain the characters a - z and numbers, no special characters or blanks.
File name - The file name should not contain any blanks or special characters: &*\/?"<>|~()!'^.
Enter one subscriber per row - Each subscriber should be entered one per row. The Access file should not contain any empty fields for email addresses other than last in the list.
File size - The file should be no larger than 8 megabyte (Mb).
Country code - When you import mobile numbers (for SMS sendings) you also need to import the country code for the mobile number. Without it, there might be a risk of the SMS messages failing to reach the subscribers.
