Email Check vs Tomba: The Honest Comparison Nobody Else Has Written
This comparison shouldn't exist. Email-Checker.net is a free single-email verification tool. Tomba is a paid email-finding and verification platform with an API, bulk workflows, and pricing that'll surprise you if you've only seen the old numbers on third-party directories. Comparing these two is like comparing a pocket calculator to a spreadsheet app - they overlap on exactly one function.
But the question keeps coming up, so let's make it useful.
Email lists decay by roughly 28% every year, and one bad campaign can push your hard bounce rate past the 2% threshold cold email teams fight to stay under. Here's the thing: if your outbound volume is under 100 emails a month, a free verifier is all you need. Over that, you're gambling with your sender reputation.
Quick disambiguation: "Email Check" here means Email-Checker.net - not emailcheck.io, not Email-Check.app.
30-Second Verdict
Pick Email-Checker.net if you need a free, one-off verification before sending a single cold email. Nothing more.
Pick Tomba if you need to find business emails by domain and verify them in bulk - and the $441+/year price tag doesn't faze you.
Skip both if you want email finding and verification in one platform without stitching tools together. Prospeo gives you 75 free emails/month with 98% accuracy, no credit card required.
What Is Email-Checker.net?
Email-Checker.net does one thing: verify whether an email address exists. It checks format, validates the domain, flags disposable addresses, then connects via SMTP and simulates sending a message to confirm the mailbox is real. Single checks are free, no signup required.
Pros: Completely free for single checks. Bulk credits are cheap - $27 for 2,500 verifications, $359 for 50,000 - and they never expire.
Cons: Returns "unknown" results when mail servers restrict SMTP probing, with no workaround. No spam-trap detection, no risk scoring, no email finding. The UI feels like it hasn't been touched since 2019. (If you're dealing with bounces at scale, see our email bounce rate benchmarks and fixes.)
Email-Checker.net can't find emails. Tomba charges $441/year and still returns unknowns on catch-all domains. Prospeo finds and verifies in one step - 98% accuracy, catch-all handling, spam-trap removal - starting at $0.01/email.
Get 75 free verified emails this month. No credit card required.
What Is Tomba?
Tomba is a proper email-finding and verification platform. Feed it a company domain, it returns employee emails. You can verify in bulk, enrich contacts, and pull data via API. It earns a 4.7/5 on G2 with users praising data accuracy and a clean UI - though that's across only 25 reviews. Its Trustpilot score sits at 3.1/5 across 21 reviews, which paints a less flattering picture.
Pros: Combined finder and verifier. Accept-all and disposable emails don't consume verifier credits. Works well with Zapier and Pabbly.
Cons: Pricing has jumped significantly. The Basic plan is $441/year (or $588 if you pay monthly). Growth runs $801/year. Pro Plus tops out at $4,041/year. Most comparison sites still show the old $39/mo Starter plan - don't trust them. Check tomba.io/pricing directly. Reviewers also flag a thin integration ecosystem, with one specifically calling out the lack of connections to professional networking platforms.
We tested the domain search and found the results accurate, but the credit burn on large companies adds up fast. Search a 500-person company and you'll blow through 50 credits on a single domain lookup since Tomba charges 1 credit per 10 emails returned.
Head-to-Head Feature Comparison
| Feature | Email-Checker.net | Tomba | Better Choice |
|---|---|---|---|
| Primary function | Verification only | Finding + verification | Tomba |
| Email finding | No | Domain, name, author search | Tomba |
| Bulk support | Paid credits | All paid plans | Tomba (built-in) |
| Free tier | Unlimited single checks | 25 searches/mo, 50 verifications/mo | Email-Checker.net |
| Paid pricing | $27 / 2,500 credits | $441/yr (Basic), $801/yr (Growth) | Email-Checker.net |
| Integrations | None | API, Zapier, Pabbly, extensions | Tomba |
| Catch-all handling | Returns "unknown" | Confidence scoring | Tomba |
Email-Checker.net wins on price and simplicity for pure verification. Tomba wins everything else - if you can stomach the cost.
When to Use Which
Just checking one email before hitting send?
Email-Checker.net. Free, instant, no account needed. That said, most serious outbound teams prefer paid verifiers with APIs, bulk cleaning, and clearer handling for risky or unknown cases - which tells you where Email-Checker.net sits in the hierarchy. (If you want a deeper breakdown, see how to check if an email exists.)
Building a prospect list from company domains?
Tomba. It's built for exactly this workflow, and the credit system rewards volume. Just budget carefully - those credits disappear faster than you'd expect on mid-size companies. If you're building lists end-to-end, this overlaps with how to generate an email list.
Running outbound at scale?
Neither tool handles this well alone. You'd need to stitch together multiple products, and in our experience that's where deliverability starts to slip because data quality varies between tools. A platform like Prospeo covers finding, verification, and enrichment in one place, with a proprietary 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering - none of which Email-Checker.net offers. The free tier gives you 75 emails per month with no credit card. Paid plans run about $0.01 per lead, with native integrations into Salesforce, HubSpot, Smartlead, Instantly, and Lemlist so verified contacts flow straight into sequences. (If you're scaling sequences, also see email velocity and our email deliverability guide.)
Stitching a free verifier to a paid finder is how bounce rates creep past 2% and sender reputation tanks. Prospeo's proprietary 5-step verification handles catch-alls, honeypots, and spam traps - the exact gaps Email-Checker.net leaves open. One platform, 300M+ profiles, 98% email accuracy.
Replace two tools with one that actually protects your domain.
FAQ
Is Email-Checker.net really free?
Yes, for single checks - unlimited, no signup. Bulk verification starts at $27 for 2,500 credits, scaling to about $0.0072/check at higher volumes. Credits never expire, which makes it one of the cheapest pure-verification options out there.
Why does Tomba pricing look different on comparison sites?
Third-party directories often lag by months or years. Many still show Tomba's old $39/mo Starter plan. The current Basic plan is $441/year, with Growth at $801/year. Always check tomba.io/pricing directly before budgeting.
Is Tomba better than Email-Checker.net for bulk verification?
For verification alone, Email-Checker.net's bulk credits are cheaper. But Tomba bundles finding and verification together, which eliminates a step. If you already have your list, Email-Checker.net saves money. If you're building the list from scratch, Tomba makes more sense - though at $441/year for the Basic plan, it's worth comparing against alternatives that offer similar functionality at lower per-lead costs.
What's a good alternative to both tools?
Look, if you're reading this comparison you're probably trying to solve two problems at once: finding emails and making sure they're real. Prospeo handles both with 300M+ professional profiles and a 7-day data refresh cycle. The free tier includes 75 emails per month - three times Tomba's free verification quota - and paid plans start without contracts or sales calls. The consensus on r/sales threads about email tools is that all-in-one platforms save more time than they cost, and we'd agree.
