List upload requirements

First, ensure that your list is in the proper format. Your list must be in either a .csv (comma delimited) or .txt (tab delimited) format to import into your VerticalResponse account.

We recommend eliminating any unnecessary data columns from your file. For a mailing list, your file must contain email addresses or complete postal addresses but other fields are optional and only needed if you plan to personalize your email or segment your list using the data. Unnecessary data increases the possibility of a typo or extra character.

You may want to review your list and remove any special characters ($ ! , {} %) that may interfere with the import process. Try using a find and replace function in Excel (or similar application) to eliminate any extra spaces, quotes, tabs or commas.

You might also try breaking your list into smaller files. Any list over that size may be truncated to 40,000 during the list upload process.

Note: You must call us for authorization to load a list larger than 40,000 names.
