What should count as revenue from a reactivation campaign?

A reactivation campaign reaches an old customer list and a purchase follows. Did the campaign cause that revenue? Sometimes the connection is clear. Sometimes the customer already had an open quote, reordered on a regular cycle, or responded to a sales conversation that began before the message.

There is no useful attribution rule that can repair an undefined commercial agreement after the send. Before launch, agree what is being measured, how the baseline is set, which orders qualify and which records resolve disputes.

Define the eligible audience

Save the audience as a dated, reviewable segment before any message goes out. Record inclusion criteria, exclusions, suppression status and the fields used to select recipients. Confirm that the proposed contact is permitted under the rules that apply to the business and recipient; if permission is unclear, exclude the record until it is resolved.

Separate dormant customers from active opportunities, current negotiations, service cases and recent orders. These groups have different starting conditions. If they are mixed into one total, the campaign may receive credit for demand that already existed or miss a useful result because the customer was classified inconsistently.

Choose the revenue event

“Revenue” could mean an order placed, an invoice issued, payment received or cash retained after refunds and credits. Select one event and a consistent source of truth. If the commercial share is calculated on collected revenue, define how partial payments, cancellations, tax, delivery charges and later adjustments are handled.

Then choose an attribution window that matches the sales cycle and agree what starts it: message delivered, recipient click, reply, quote or another recorded event. The window is a contract choice, not a universal marketing constant. Keep the campaign identifier on the enquiry or order where the workflow supports it.

Separate influence from incrementality

A tagged order can show that a campaign touch preceded a purchase. It cannot, by itself, prove the purchase would not otherwise have happened. If the agreement promises a share of attributable revenue, define that term directly. If the decision requires an estimate of incremental lift, agree a credible comparison design before the campaign rather than trying to construct one afterwards.

For a small or highly segmented audience, a holdout may be impractical or commercially undesirable. You can still report observed orders associated with the agreed campaign rules, while being clear that this is attribution under the agreement and not proof of incremental effect. Precision about the claim protects the relationship.

Make the reconciliation reproducible

At the end of the window, both parties should be able to compare the eligible audience, campaign events, pre-existing opportunities and qualifying transactions. Keep a record of excluded sales and the reason for exclusion. Assign who resolves missing identifiers, late refunds and disputed matches, and specify when the report is final.

A useful report states the rule, the data source, the period, the observed result and its limits. It should allow another person to repeat the calculation without relying on someone’s memory of what “campaign revenue” meant.
