# Upload a Batch of Tags
> How to upload eligibility data and other tags to the Mention Me platform using the Upload Tags tool.
Using the new platform at [app.mention-me.com](https://app.mention-me.com)? See [Upload a CSV](/knowledge-v2/data/uploads) instead. The page below describes the legacy Upload Tags tool. Concepts are unchanged, only the UI is different.
The Upload Tags tool lets you upload data directly to the Mention Me platform. If SFTP isn't an option for transferring data such as an eligibility feed, this feature processes eligibility data with a simple file upload and field mapping.
## Steps to Upload Tags
Log into your dashboard, go to **Settings & Tools** then **Upload tags**, or search for "Upload tags" and select the first option.
You'll see a list of possible tags to upload.
The document to upload must be a **CSV file**. The first row should always include the required headers. For a list of emails (e.g., new customers who qualified for a reward), select the option from the dropdown and download the sample document.
The sample file contains all required headers and one example under each for your reference.
You can map your own headers to mandatory and optional fields before each upload. This step appears right after dropping your file onto the page.
Mandatory fields are always visible during mapping. Optional fields might be available depending on your upload choice, but these are hidden by default. Click the **Optional fields** bar to see and map these.
Mapping fields triggers the first stage of validation. If your data format is incorrect, you'll see a red error message straight away.
The tool checks the first \~100 rows in your file and shows you any errors, like an invalid email address. If you continue, the rest of the rows are validated on our servers. Any row with an issue will be skipped during processing.
When all fields are mapped and there are no validation errors, click **Upload** to start processing your file.
## What Happens Next?
Once the process finishes, you'll see a confirmation popup showing how many rows failed and how many were processed successfully. Valid rows are sent to the Tag queue, ready for use in your campaign.
