When importing subscribers into MailBul, you can do it from text files, csv files or external sql database.
If you decide to do it from csv files, your csv file has to contain proper header columns and one of the column must be named email. If you don’t have the email column, the application will not import your file.
Here’s how a proper file should look like:
Email,"First name","Last name","Age" firstname.lastname@example.org,John,Doe,25 email@example.com,Jane,Doe,22 firstname.lastname@example.org,Joe,Doe,12 email@example.com,Jen,Doe,15
The first row of the file is considered the file header. If your email list doesn’t contain custom fields for each header column, those custom fields will be created automatically.
