How we checked: prices, credits and what a credit buys come from each vendor's own pricing pages and help centers, read October 30, 2026. Several pricing pages load their numbers in the browser; where we could not read a figure, we say so. Coverage and compliance claims are the vendors' own. The cost-per-contact table is our arithmetic.

Lusha
Lusha is the simplest way for a small team to get both emails and direct dials: a free plan with 40 credits a month, a Chrome extension, and paid plans from $37.45 a month billed yearly for 400 credits. An email costs 1 credit and a phone number 5. Monthly plans roll unused credits over, up to twice the monthly limit. Lusha lists SOC 2 Type II, GDPR certification by ePrivacyseal and CCPA validation, and syncs to Salesforce, HubSpot, Zoho, Pipedrive and others.
Apollo
Apollo pairs a 240M-contact database with sequences and dialing, which makes it the all-in-one choice for a founder doing outbound. Its free plan has no time limit, Basic is $49 a month billed monthly, and Professional $99. Credits are pooled across the team and do not roll over; accounts without a verified company domain are capped at 100 credits a month.
Hunter and FullEnrich
- Hunter: email finding and verification only, at the lowest cost per email we found ($34 a month billed yearly for 2,000 credits). Verification costs half a credit, and you pay nothing when nothing is found.
- FullEnrich: a "waterfall" that tries 25+ providers in turn, charging only when it finds data. It keeps no database of its own and is priced per credit: 1 for a work email, 10 for a mobile.
