## Example

Your newsletter campaigns captured **\$9,200** in subscribe value this month across 1,840 subscriptions:

| Channel    | Subscribe Value | Subscribes | Avg Value |
| ---------- | --------------- | ---------- | --------- |
| Meta Ads   | \$5,500         | 1,100      | \$5.00    |
| Google Ads | \$2,760         | 552        | \$5.00    |
| TikTok Ads | \$940           | 188        | \$5.00    |

## How It Works

Subscribe Value sums the monetary value assigned to each subscribe event tracked by the Upstack pixel. When a visitor subscribes to your newsletter or mailing list, the event can include a custom value representing expected lifetime value or subscriber worth. This metric helps quantify the total pipeline value generated by your email acquisition campaigns.
