How to use the Apollo email finder (and check the emails before you send)

So, how do you actually find an email with Apollo? You search its contact database by name or company, reveal the address with a credit, then export it or drop it straight into a sequence. That’s the whole workflow, and most people get through it in under a minute once they know where to click.

Here’s how each step breaks down.

1. Search for a person or company
Open the People search inside Apollo and type in a name, a company, or both. If you’re prospecting at scale, searching by company first and then filtering by title usually gets you there faster.

2. Narrow with filters
Apollo’s left-hand panel lets you filter by job title, seniority, company size, industry, location, and even the technology a company uses. The more filters you stack, the smaller and more targeted your list gets, which matters once you start paying per reveal.

3. Reveal emails (and phone numbers, if you want them)
Click “Reveal” on a contact and Apollo shows you the email. You can do this one contact at a time or select a batch and reveal them all together, which is the better move if you’ve already filtered your list down.

4. Export or send straight to a sequence
Once you’ve got your contacts, you can export them as a CSV, push them into a CRM like HubSpot or Salesforce, or add them directly to an Apollo sequence. No need to leave the platform if you’re sending from Apollo too.

Find an email in Apollo in 4 steps

The Apollo email finder works from Apollo’s contact database. You search it, reveal an email with a credit, and send. The whole process has four steps, and each one takes a few clicks.

First, go to Apollo.io and sign up using a corporate email address. Once you’re in, open the People search. You’ll see a search bar plus a panel of filters on the left side of the screen.

Second, narrow the results. Apollo offers advanced filters for large-scale prospecting, including job title, seniority, company size, industry, location, and technology used. The more filters you apply, the tighter your list gets.

Third, reveal the emails. Click “Reveal” to see a verified email address. Each reveal costs one email credit. You can reveal contacts one by one or select a batch and reveal them together.

Finally, export contacts as a CSV file, push them to your CRM, or add them to an Apollo email sequence for automated follow-up. Export activity also consumes credits on paid plans, so track your usage in the first month.

How many credits does each email cost

Credit math is the part of Apollo that catches people off guard. The seat price on the pricing page is only the starting point.

An email costs 1 credit. A verified phone number costs 8, whether it’s a mobile, a direct line, or an office extension. If you reveal both an email and a phone number for the same contact, that’s 9 credits total.

Credits don’t roll over. Unused credits expire at the end of each billing cycle, including add-on credits. So if your team doesn’t use them, they vanish.

Overage credits cost $0.20 each with a 250-credit minimum top-up. Active outbound teams routinely spend $150 to $400 per user per month once overages are factored in.

Here’s what each plan gives you on annual billing:

An email costs 1 credit. Basic on annual billing is $588 a year for 30,000 emails, about $19.60 per 1,000.

Tip: If you only want emails and don’t plan to call, skip the phone reveal entirely. That one change cuts your credit burn by nearly 90% per contact.

How accurate are Apollo emails

This is where things get interesting. Apollo’s email finder page claims 98% accuracy. Apollo’s knowledge base says 91%. Four other Apollo pages describing the same verification process state 97%, 91%, 91%, and “more than 90%” alongside an 84% match rate. All five were live on the same day.

So which number is real? The largest public third-party test that included Apollo measured 91.3% accuracy on 5,000 contacts, which lands closer to Apollo’s support documentation than its marketing page. That test was published by Anymail Finder (a competitor, so weigh that accordingly).

In practice, accuracy depends on who you’re targeting:

• •

  US mid-market and enterprise contacts in tech and SaaS resolve reliably.

• •

  Small businesses, agencies, and regional companies are mixed because Apollo’s coverage is thinner.

• •

  Catch-all domains are weak, since servers that accept any address make verification impossible.

• •

  Non-US contacts: real-world bounce rates of 15–35% are consistently reported by users outside the United States, particularly in Europe and APAC.

What Apollo’s email status labels mean

Verified includes emails you manually enriched or uploaded that Apollo knows to be verified. Verified emails cost 1 credit per contact. If an Apollo-verified email bounces within 30 days of you purchasing it, Apollo automatically refunds the credit to your account.

Unverified includes emails Apollo was unable to verify, manually edited contacts, CSV imports, CRM uploads, or API-created entries. It also includes emails where Apollo has low confidence in their validity.

Update required means Apollo has detected a job change for this contact.

Unavailable is an email that Apollo is unable to find or verify. Apollo doesn’t charge you any email credits for contacts without known, valid email addresses.

The important detail here: Apollo’s “verified” label means the address passed Apollo’s checks at some point in time, not that it will accept your message today.

How to verify Apollo emails before sending

B2B data decays at an estimated 2–3% per month (per Tomba’s analysis), so an export that sat for eight weeks could have a bounce rate well above what your domain can absorb safely. Here’s a simple pre-send workflow:

1. 1.

   Export from Apollo with the verified filter on where possible

2. 2.

   Run the full list through a standalone verifier to catch decay and catch-alls

3. 3.

   Segment catch-all results separately and warm into them slowly

4. 4.

   Suppress role-based addresses (info@, sales@) unless they’re your target

5. 5.

   Re-verify any list older than 30 days before reusing it

Why a waterfall improves email coverage

A single database will always have gaps. Waterfall enrichment solves this by querying several data providers in sequence: if the first source comes back empty, the second one tries, then the third, and so on until a verified email is found or all sources are exhausted.

The result is higher coverage and fewer “unavailable” contacts compared to relying on one vendor alone. Tools like lemlist use this approach, pulling from 14+ providers in a single lookup and charging only for emails that are successfully verified. If you’re exporting from Apollo and finding too many unavailable contacts, running those gaps through a waterfall is a practical next step.

Find emails with the Apollo Chrome extension

The Apollo extension is a Chrome add-on that connects your browser to Apollo.io’s contact database. When you open a LinkedIn profile, a company website, or a Gmail thread, the extension reads the page context (name, company, domain) and matches it against Apollo’s records to reveal a work email and, where available, a direct or mobile phone number.

Setup takes a few minutes:

1. 1.

   Download the Apollo.io extension from the Chrome Web Store and log in with your Apollo account

2. 2.

   Visit a prospect’s LinkedIn profile or any company website. The Apollo sidebar appears on the right automatically.

3. 3.

   Click to reveal the prospect’s email and phone number. From the sidebar, you can add them to an Apollo list or enroll them in a sequence without leaving the page.

On LinkedIn company pages, the extension shows a list of employees. Filter by job title and reveal multiple contacts in bulk, which is faster than opening individual profiles.

The tradeoff is the one a benchmark found: the most addresses returned, the lowest accuracy of the top three, and an 18.7% catch-all rate. So validate before a large send, even when the extension labels an email as verified.

Tip: The Chrome extension draws from the same credit pool as the main app. Every reveal on LinkedIn counts against your monthly allocation, so bulk reveals can drain credits quickly.

Other email finders compared

Apollo is a strong all-in-one platform, but if your primary goal is email accuracy or if you also want to send outreach from the same tool, the market has a few options worth comparing.

Apollo bundles prospecting, enrichment, and sending into a single credit system, which works well if your team lives inside Apollo for everything. However, two things decide whether it works for you: how many credits you burn, and how many of the emails you pull actually reach an inbox.

If you’re finding that Apollo’s single-database approach leaves too many contacts marked “unavailable,” or if bounce rates are climbing above 5%, a waterfall-based finder can fill those gaps. lemlist’s Email Finder queries 14+ providers per lookup, charges only for verified results, and connects directly to multichannel campaigns (email, LinkedIn, calls, SMS) without exporting or importing CSVs.
