Choose Hunter if your motion is email-led and domain-based: you want to find and verify work emails at scale, you value the cleanest email data reputation in the category, and you want the most generous free plan around (50 credits a month plus a mailbox). Hunter does email, and only email, very well.
Choose Lusha if you prospect off LinkedIn and need full contact records with both verified emails and phone numbers, delivered through a fast Chrome extension on transparent credit pricing with a free tier. Lusha is the better fit when phones matter and your list-building happens profile by profile.
Choose a waterfall enrichment layer like Enrich if your priority is the highest match rate per contact at a predictable cost. Waterfall enrichment queries several providers per record and keeps the first verified hit, which lifts fill rates above any single source and returns both email and phone in one record.
