Is Emailable Accurate? Its Guarantee, Its Limits, and a Fair Test

What Emailable checks

The homepage lists the checks it runs on each address: syntax, domain validation (does the domain exist and accept mail), disposable detection, free-provider detection, role detection and accept-all detection. It sorts the results into four groups:

Emailable status	What it means	What to do
Deliverable	The server accepted the mailbox	Send
Undeliverable	The mailbox or domain doesn't exist	Remove and suppress
Risky	Accept-all, role, disposable and similar	Decide per campaign
Unknown	The server didn't give an answer	Re-check later; not charged

On accept-all, Emailable's own wording is candid: these servers "appear to accept all emails, but can still cause bounces." That is exactly right, and it's true for every verifier. A server that accepts every address gives no way to confirm one by asking.

What the guarantee actually says

The guarantee page promises deliverability rates on addresses it classed Deliverable: "97%+ deliverability guaranteed on email addresses managed by Microsoft" and "99%+ deliverability guaranteed on all other email addresses." Paying customers get a 100% refund for qualifying emails that miss it.

The conditions are what matter:

• Only Deliverable rows count. Risky and unknown rows are outside it.
• Emailed within 24 hours of verification.
• At least 1,000 unique addresses in the list.
• Bounces must be because the address doesn't exist. Poor sender reputation is excluded, along with other "unqualified bounces".
• The addresses must come from "your own opt-in source."
• Claims go to support within 72 hours of the discrepancy.

The Microsoft line is a useful tell. Microsoft-hosted mailboxes (Outlook, Microsoft 365) are among the hardest to verify reliably, and Emailable prices that difficulty into a lower guaranteed threshold. That is honest. It also tells you where to look first when you test.

The opt-in condition is the important one for sales teams. Cold lists from Apollo, scraping or a data vendor don't qualify. If that's your use, judge Emailable on your own bounce numbers, not the guarantee. We compare guarantees across vendors in email verifier bounce guarantees.

The other headline

The homepage calls Emailable "the most accurate email verification platform". That's a marketing claim; the page doesn't say what test supports it. We know of no independent audit behind any vendor's accuracy claim, and SimpleVerifier publishes no accuracy percentage of its own. Testing on your own list is the only comparison that means anything.

How to test Emailable on your own list

1. Sample 500 random rows from the list you'll send, with the email list sampler. The 250 free credits cover half of it.
2. Run the sample through Emailable and one other verifier.
3. Compare row by row in the verifier comparison tool. Pay attention to Microsoft-hosted domains; the bulk email provider lookup tags them.
4. Send to rows both tools call deliverable within 24 hours, so the guarantee window applies if your list qualifies.
5. Count hard bounces after 72 hours with the bounce rate calculator. For cold email, stay under 2%.
6. Send a separate batch of 50 risky (accept-all) rows if you plan to use them, and count those bounces on their own.

What to do with each status on a cold list

If the guarantee doesn't cover your list, these defaults keep bounces down:

• Deliverable: send, in your main sequence, ideally within a day or two of the check.
• Risky, accept-all: a separate small batch after the main send, with a stop rule at 2% hard bounces. Don't let them make up more than a small share of any one inbox's daily sends.
• Risky, role or disposable: drop for cold outreach. Role inboxes are shared and more likely to complain.
• Undeliverable: suppress in your sequencer, not just delete, so a later import can't bring them back.
• Unknown: re-run the next day. They're credited back, so the second pass costs nothing.

When Emailable fits

• You clean opt-in lists (newsletter signups, customers) and want a written deliverability guarantee.
• You can send within 24 hours of verifying, so the guarantee window is usable.
• You want SOC 2 Type II, which the homepage lists.

Where SimpleVerifier fits

For cold and B2B lists, the honest handling of unconfirmable rows matters more than a guarantee you can't claim. SimpleVerifier reports every catch-all as risky, never valid, and grades it higher, medium or lower likelihood with the reason (how grading works). Every other row gets a live SMTP mailbox check.

Pricing is flat for monthly cleaning:

• Pro, $39 a month: Unlimited email verification.*
• Starter, $9 a month: 2,500 emails a month.
• Free: 100 checks with a Google sign-in.

*Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.

At Emailable's list price, 100,000 checks are $420 per run. Pro also includes phone format checks, an email finder, an API, an MCP server and integrations with Instantly, Smartlead and Mailchimp. Compare on the pricing page, or run the same 500 rows on the verify page.
