Why Apollo's "Verified" Emails Are Killing Your Deliverability (And the 4-Step Fix)
Apollo's verified emails have a 20-40% bounce rate. Here's the 4-step process BuzzLead uses to scrape and verify 150k+ emails a month safely.
Most cold emailers trust Apollo's "verified" label and send straight from the export. That trust is costing them thousands of leads a month, and burning the domains they spent weeks warming up. At BuzzLead, we scrape and verify over 150,000 emails every single month without relying on Apollo's verification layer, and we consistently hit 10%+ positive reply rates for our clients. Here's exactly how.
The Problem With Apollo's "Verified" Filter
Apollo is a genuinely useful tool. Over 500 million B2B contacts, solid filtering by industry, revenue, headcount, job title, I'm not here to trash it. But there's one thing that trips up almost every cold email operator: the "Verified Emails" filter.
When you check that box, you assume you're getting clean, deliverable addresses. You're not. Only 60-70% of emails labeled "verified" in Apollo are actually valid. The rest bounce. Apollo updates its database roughly once per quarter, so by the time you're pulling contacts, a chunk of those "verified" emails belong to people who've changed jobs, had their inboxes deactivated, or simply never had a real address in the system to begin with.
Run a campaign against a list with a 20-40% bounce rate and watch what happens to your domain reputation. Open rates crater. You start landing in spam. Eventually the inbox is burned entirely. I've talked to plenty of people who couldn't figure out why they were getting 10% open rates, almost always, it traces back to this exact problem.
There's a second issue: export limits. The basic Apollo plan caps you at roughly 1,000 email exports per month. If your search returns 15,000 contacts, you're waiting eight months to pull them all. That's not a workflow, that's a bottleneck.
Step 1: Build Your List in Apollo, But Skip the Verified Filter
Go into Apollo and build your search the normal way, filter by industry, location, company size, job title, whatever fits your target market. In a sample search for marketing and advertising companies in the US with 11-50 employees, targeting owners and founders, you might surface 15,000 contacts.
Here's the move most people miss: do not click "Verified Emails." Pull everything. Even contacts where Apollo has no email address on file are worth keeping, because the next step can often surface those addresses anyway. Copy the full search URL. That URL is what you're taking into step two.
Step 2: Use Export Apollo to Bypass the Credit Cap
Export Apollo (exportapollo.io) is a third-party scraper that reads your Apollo search URL and delivers a full CSV, regardless of how many contacts are in the list. You don't need an expensive Apollo plan. A basic $30-50/month Apollo account is enough to authenticate the search. Export Apollo charges separately, typically around $36 for a one-time list pull of 15,000 contacts.
A few minutes after you submit the URL, they email you a CSV. It will include contacts with email addresses and contacts without. I split these into separate sheets immediately: one tab for everything, one for contacts where an email was found, one for contacts without. The "emails found" sheet is what moves forward into verification.
There are other scraping tools that work similarly, I've also used Magically and have built custom scrapers. The point is to stop letting Apollo's export limits dictate your list size.

Step 3: Run Every Email Through Million Verifier
Million Verifier is an email validation tool that actually pings each address to confirm it can receive mail. For $20-50 in credits, you can run thousands of emails through it. Drop your CSV in, wait a few minutes, and you get a report broken into three buckets: good, risky, and bad.
Good emails are safe to send. Full stop. For a list of 9,300 contacts pulled via Export Apollo, I typically see around 4,500 come back as verified good. Those go straight into the campaign.
Bad emails get cut. They're the ones that would have bounced and dragged down your domain reputation.
Risky emails, also called catch-all addresses, are where most people make a mistake.
Step 4: Recover Risky Emails With Scrubby
Catch-all means the receiving server accepts all incoming mail without confirming whether the specific address exists. Million Verifier can't tell you if these are good or bad, so it flags them as risky. Most people either send to all of them and absorb the bounce damage, or they throw the whole batch away.
Both are wrong.
Scrubby.io is a catch-all validation tool that digs deeper into risky addresses and separates the deliverable ones from the dead ones. In the past month alone, I ran 5,500 risky emails through Scrubby. It recovered 4,200 of them as safe to send. Only 1,300 were genuinely bad.
That's 4,200 leads most operators are leaving untouched because they don't want to deal with the risky bucket. And since almost nobody is working these contacts, there's less competition in those inboxes too.
Looking at the full picture: from a starting list of 9,300 contacts, roughly 2,000 (20-25%) were bad emails that would have wrecked deliverability. The four-step process filters those out before a single send.
Key Takeaways
Apollo's "verified" label is not a guarantee. Expect 60-70% actual deliverability at best, and a potential 20-40% bounce rate if you send blind.
Apollo's export limits (around 1,000/month on basic plans) are a workflow killer. Use a third-party scraper like Export Apollo to pull full lists for a flat per-list fee.
Million Verifier is the core verification layer. It actively pings addresses and sorts your list into good, risky, and bad.
Don't discard risky/catch-all emails. Run them through Scrubby. In practice, roughly 75-80% of risky emails can be recovered as safe to send.
High bounce rates destroy domain reputation, which kills open rates, triggers spam filters, and burns inboxes. Fix the list quality first; everything else follows.
Frequently Asked Questions
Why shouldn't I just use Apollo's built-in email verification? Apollo only updates its database once per quarter, and even emails it labels "verified" have a real deliverability rate of just 60-70%. That means up to 40% of your sends could bounce, which damages your domain reputation and pushes future emails into spam.
What does "catch-all" or "risky" mean in email verification? A catch-all server accepts all incoming mail for a domain without confirming whether the specific address exists. Verification tools like Million Verifier can't determine if these addresses are valid, so they flag them as risky. A tool like Scrubby.io does additional validation to separate the deliverable catch-all addresses from the bad ones.
How much does this four-step process actually cost? Roughly $30-50/month for a basic Apollo account, around $36 per large one-time list pull via Export Apollo, and $20-50 in Million Verifier credits depending on volume. Scrubby charges separately for catch-all validation. Total cost is a fraction of what burned domains and wasted outreach cost in lost opportunities.
Why pull all contacts from Apollo instead of just the ones with emails on file? Apollo doesn't have email addresses for every contact in its database. Skipping those contacts means missing leads that Export Apollo or other scrapers can sometimes surface through additional data sources. Starting with the full list maximizes the leads you can actually reach.
