SMS Attribution Windows: Four Providers’ Rules Compared

Selected article findings, not the complete article.

SMS attribution windows depend on the eligible event, the clock start and other credit rules, not just the number of days. In four selected providers’ public documents captured on 8 and 9 November 2026, Klaviyo, Attentive and Omnisend describe recalculating historical attribution after settings change. Postscript says previous analytics are not recalculated.

Attentive’s captured page lists a five-day click window in its new-customer table, while later prose calls thirty days the default. We leave that conflict unresolved and do not assume an existing account uses either value. Postscript has a coupon-code override; Omnisend requires an SMS click and offers sent-versus-engaged clock options.

The existing calculator compares only two providers’ declared time windows. It does not reproduce full credit logic, inspect accounts, identify additional purchases or measure Zobi performance. See the four-provider rules, source dates and method on the page.
