File Upload and Export Formats

Prepare contact files for upload and understand the file format used for exports.

Supported upload formats

Use Microsoft Excel© files in .xlsx or .xls format for contact-list uploads, campaign uploads, and list updates.

Prepare your file

  • Place each recipient mobile number in the first column, Column A.
  • Use full international-format mobile numbers, for example 353861111111 or 00353861111111.
  • Do not leave blank rows between records.
  • Do not use formulas in uploaded cells.
  • Put any additional contact information in later columns.

Use column headers for Smart Tags

For a personalised campaign, put the column names in the first row and choose the option to import column names when you upload the file. Smart Tags use those column headers to insert the matching value for each recipient.

Exports

List exports and Quick Export downloads from reports are delivered as Microsoft Excel© .xls files.
