To send your next campaigns, it's very important to consider that deleting a data source and uploading new numbers will be slow. Therefore, we recommend uploading a new version, which means updating this data source. Don't worry if all your new numbers are different from the previous ones: updating an existing data source is the best solution.

How to do this? From 'Add Data Source,' select CSV or Copy and Paste, and we will recommend updating existing data as the first option:

Click 'Update' and indicate through CSV or Copy-Paste the new numbers. Configure what to do with the new data provided.

The new contacts will be created, and you must delete old contacts to remove contacts from previous campaigns.

Continue, and in a moment, the CSV with your contacts will be updated. You will have the numbers available and the option to send a bulk campaign.
