The email finder API that returns business email, personal email & mobile
Most email finder APIs stop at business email. Kendo gives you business email, personal email and personal mobile from one API: one key, one vendor, and you only pay for the data you request.
Powered by 150M personal emails, 90M business emails and 12M verified mobile numbers.

Why Kendo's data model wins
Three arguments engineers actually evaluate before wiring an enrichment API into production.
The data others don't have at scale
Business emails bounce. InMail has limits. The contact data that actually starts conversations — personal email and mobile — is what most enrichment APIs don't have.
Kendo's dataset includes 150 million personal emails and 12 million verified mobile numbers, each available as a first-class field.
Mobile numbers without the Apollo asterisk
Hunter has no phone data. Apollo keeps numbers for higher tiers. Kendo has a dedicated mobile endpoint on every plan. Call it when you need a phone and skip it when you don't, so an email lookup never costs you phone prices.
More signal per dollar
Hunter's entry pricing buys business email only. Apollo bundles personal email but still gates phones. Kendo starts at $14/mo when billed annually ($17/mo month-to-month) while giving you all three contact types on every plan.
For teams embedding lookups in multi-tenant products, lower per-credit cost plus richer payloads compounds: fewer vendor reviews, less integration debt, and a stronger story for your customers.
