The MillionVerifier Alternative That Actually Resolves Catch-Alls

Looking for a MillionVerifier alternative? OrbiSearch resolves 11.5x more catch-all emails than MillionVerifier (which flags them as "Risky" without verifying), at a lower per-email price. SEG-protected and greylisted resolution included. From $0.0002 per validation, pay-as-you-go, credits never expire.

Why teams switch from MillionVerifier to OrbiSearch

Catch-alls flagged, not verified

MillionVerifier classifies catch-all emails as "Risky" and refunds the credit, which means you get no answer. For catch-all resolution they hand you off to Scrubby, a third-party service that costs $0.0049-$0.0078 per credit (20-39x OrbiSearch's "From $0.0002") and works by sending real emails to your prospects from a network of Gmail accounts they control, then waiting up to 72 hours to see what bounces back. OrbiSearch resolves catch-alls in seconds without sending any emails to your prospects, and without a second vendor.

40-60% of B2B domains are catch-all

If you're running cold outreach, "Risky" is most of your list. MillionVerifier's headline price only looks low because most of your catch-all results are unanswered, not because they're cheap to resolve.

No SEG or greylist resolution

OrbiSearch resolves SEG-protected (Mimecast, Proofpoint, Barracuda) and greylisted emails. MillionVerifier does not.

The catch-all problem

Catch-all domains accept mail for any address, making it impossible for traditional verifiers to check if a specific mailbox exists. MillionVerifier flags these as "Risky". OrbiSearch resolves them.

Flags as "Risky"

Classifies catch-all emails as "Risky" without checking mailbox existence. Does not charge credits for these results, but provides no actionable information. For catch-all resolution, they partner with third-party Scrubby (24-72 hours, sends test emails).

Cost per useful answer

MillionVerifier doesn't charge for catch-all/Risky results - but they don't verify them either. The "free" isn't a discount, it's a service gap.

Worked example: 100k B2B list, ~50% catch-all (industry norm).

Frequently Asked Questions

Why look for a MillionVerifier alternative?

The two most common reasons are catch-all handling and SEG/greylist resolution. MillionVerifier doesn't charge for catch-all results - but it doesn't verify them either, just flags them as 'Risky'. For B2B cold outreach where 40-60% of domains are catch-all, that means a large share of your list is unresolved. Their workaround is to hand you off to Scrubby, which costs $0.0049-$0.0078 per credit, takes up to 72 hours, and works by sending real emails to your prospects from a network of Gmail accounts they control to see what bounces back. Teams that need definitive catch-all answers in seconds, plus SEG-protected and greylisted resolution that MillionVerifier doesn't offer, typically switch.

What's the best MillionVerifier alternative for catch-all emails?

OrbiSearch resolves 11.5x more catch-all emails than MillionVerifier on the same Apollo-sourced benchmark, in seconds rather than 24-72 hours, and without sending any emails to your prospects. LeadMagic also positions on catch-all resolution. ZeroBounce, NeverBounce, Clearout and Emailable flag catch-alls but don't fully resolve them at the mailbox level.

Is OrbiSearch actually cheaper than MillionVerifier?

Yes. OrbiSearch is 23-34% cheaper per email at every published volume tier (e.g. $103 vs $149 at 100k, $311 vs $449 at 1M). Once you account for catch-all resolution, the gap widens further: MillionVerifier doesn't charge for catch-all results but also doesn't verify them, so on a 100k list with 50% catch-all you get 50k useful answers from MillionVerifier vs 100k from OrbiSearch - making OrbiSearch around 65% cheaper per useful answer.

When is MillionVerifier still the right choice?

MillionVerifier is a strong pick when you don't need catch-all resolution and want ESP-integrated list hygiene. Its EverClean automated daily list cleaning, signup form widget, and 17+ ESP integrations (Mailchimp, HubSpot, ActiveCampaign) are genuinely useful for that workflow. For cold-outreach use cases where catch-all and SEG-protected resolution matter, dedicated alternatives are a better fit.

Does MillionVerifier verify catch-all emails?

No. MillionVerifier classifies catch-all emails as 'Risky' without verifying individual mailboxes. They do not charge credits for these results, but the results are just a flag, not a verification. Users report that 25-30% of emails flagged as 'Risky' are actually valid. For catch-all resolution, MillionVerifier partners with a third-party service called Scrubby which sends test emails and takes 24-72 hours.

How many more catch-all emails does OrbiSearch resolve?

In a benchmark test of 2,451 catch-all emails from a real cold outreach campaign, OrbiSearch resolved 11.5x more catch-all emails than MillionVerifier. OrbiSearch uses proprietary dual-layer mailbox detection to return definitive results in seconds without sending any emails.

Is OrbiSearch cheaper than MillionVerifier?

Yes, OrbiSearch is 23-34% cheaper at every volume tier. At 1,000,000 emails, OrbiSearch costs $311 compared to MillionVerifier's $449. However, MillionVerifier does not charge for catch-all results, so their effective cost depends on the proportion of catch-all domains in your list. If many of your emails are catch-all, MillionVerifier's cost for the non-catch-all portion is lower, but those catch-all results are unresolved.

MillionVerifier doesn't charge for catch-all results. Isn't that better?

Not charging for catch-all results sounds good, but it means you get no useful information for those emails. They are flagged as 'Risky' with no resolution. OrbiSearch charges for all verifications but actually resolves catch-all emails, telling you whether each mailbox exists. You pay for answers, not flags.

Does MillionVerifier offer features OrbiSearch doesn't?

Yes. MillionVerifier offers EverClean (automated daily list cleaning via ESP integrations), a signup form verification widget, and 17+ native integrations with platforms like Mailchimp, HubSpot, and ActiveCampaign. If you need automated list hygiene integrated with your ESP, MillionVerifier has more tools for that.

How was the catch-all benchmark conducted?

The benchmark used 2,451 confirmed catch-all emails from a real cold outreach campaign (October 2025). Each email was run through both OrbiSearch and MillionVerifier. The number of emails successfully resolved to a definitive deliverable or undeliverable status was measured.
