What Apollo.io Does Well
- Large searchable B2B database (240M contacts and 30M companies advertised) — find people you don't have a website for yet
- Full engagement suite: AI-assisted sequences and a parallel dialer
- 200+ integrations, including CRMs such as Salesforce
Best for: Sales teams that want an all-in-one platform and will actually use most of it
Where EmailKing Fits
Apollo.io is priced per seat and is a full platform to learn — more than you need if you only want the emails published on websites you already know.
EmailKing's approach is simple: you give it the websites you already know, it reads the page live, decodes obfuscated addresses (mailto links, [at]/(at) spellings, Cloudflare email protection, encoded strings), and checks the site's contact/about/team pages when the main page shows none. Each address gets a syntax check, a DNS MX lookup, a disposable-domain check and a label showing whether it matches the site's domain. No index means you're not limited to companies someone else has catalogued — but it also means EmailKing can only find addresses a site actually publishes, and it does not test whether an individual mailbox exists.
Verdict — Which Should You Pick
- Pick Apollo.io if: sales teams that want an all-in-one platform and will actually use most of it.
- Pick EmailKing if: your goal is pulling the emails published on websites you already know and building lists fast, starting at $9/mo. The free plan (25 URLs/mo) lets you check the fit first.
