Do not compare Apollo alternatives by homepage claims. Compare them on one repeatable sample: 25 companies, three target titles, two countries, and one outbound workflow. Measure relevant contacts found, verified emails, stale titles, duplicate people, export fields, and how much manual cleanup is required.
Then price the result by usable output. A platform with a lower seat price can become expensive if credits, add-ons, limited exports, enrichment fees, or workflow friction reduce the number of contacts your team can actually use.
That distinction mattered in Argorant's own export tests: Apollo's invalid share ranged from 39% to 48%, with one run at 46.21%. ZoomInfo ranged from 31% to 38%, including one result of approximately 34.6%. These figures apply only to the tested exports, but they show why buyers should compare the usable rows left after verification rather than the number of records initially revealed.
Using the Apollo Basic public-price snapshot checked on 20 August 2026, $588 for 30,000 annual credits is 1.96 cents per nominal credit; $65 for 2,500 monthly is 2.60 cents. If a one-credit-per-email export reproduced our tested 39–48% invalid range, excluding invalid rows alone raises that to 3.21–3.77 cents per remaining row on annual billing or 4.26–5.00 cents month-to-month, assuming full allowance use and no credited refunds.
That is an invalid-only cost floor. It does not classify catch-all, risky or unknown rows as valid. Role errors, duplicates, unused allowance and external verification can raise the cost of usable output further. Usage-credit refunds should be counted separately from subscription cash paid.
