Define the subscriber promise

The lead magnet or newsletter promise should match the audience the seller can reach.

Use a dedicated opt-in page

A focused page gives you a clean conversion rate.

Tag each seller

Source tags let you compare opt-in and later email behavior.

Judge subscriber quality later

A low-cost lead that never engages can be less valuable than a more expensive subscriber who responds.
