Your customer-facing teams operate on a tool not connected to your organization? Upload their freshest changes so your Upflow information is always up to date.

💡 Keep them informed from Upflow in return when your customers share relevant information!

❗Your customers' details can only be updated with this method if your organization is not connected to a solution overwriting their information. They can be imported into Upflow depending on your source system.

Your source system

Native integration

Start with creating a compliant spreadsheet with the information you want to update —assigned Workflow or Account manager(s), contacts who receive your reminders, details relevant to your teammates…

Create one line per contact (or per customer if you are not updating your contacts), with columns as fields you want to update. We strongly recommend naming them (however you want) to ease the mapping.

💡 Mandatory and accepted fields are listed below.

Save it as a CSV file. You can apply ";" (semicolons), "," (commas) and "|" (vertical bars) separators.

💡Separate emails with a comma to assign several account managers!
