The opportunities feature allows you to track positive replies and attach a monetary value to them, so you can calculate how much money the campaign is bringing you.

Opportunities consist of leads with the following statuses:

You can set the default lead value on the Preferences setting and when the lead is marked as interested or other positive custom statuses, its value will be added to the count. You may calculate this by using this sheet.

You can add the ticket size (Life Time Value) and an approximate conversion rate. This will calculate the monetary value and you can add it inside Instantly.

By doing so, you will have an understanding of which campaigns are really working well so you can start optimizing those by buying more domains and sending accounts to scale it further.
