How to evaluate marketing & growth products
Use these checks to build a shortlist. Listings describe products; they are not independent testing or an endorsement.
Verify attribution and consent
Check how conversions are attributed and whether reports can be reconciled with first-party events. Review consent, unsubscribe handling and data-processing terms for the markets you serve.
Measure more than activity
Compare qualified leads, activation and acquisition cost rather than sends, impressions or keyword counts alone. Include contact limits, overages and required integrations in the budget.
