mailfloss vs Scrubby
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedmailfloss compared with Scrubby
Opposite ends of the same category. Scrubby is a B2B outbound instrument that will send real mail and wait 72 hours to resolve a catch-all address, at roughly $0.005 to $0.008 a credit. mailfloss is a marketing-list autopilot at $29 a month that will not touch a catch-all. A company running both a newsletter and a cold outbound motion could reasonably buy each for its own job and should not expect either to cover the other.
Scrubby compared with mailfloss
Not really competitors so much as opposite ends of the same problem. Mailfloss runs quietly inside an ESP fixing typos and removing decayed subscribers from $29 a month, aimed at newsletters and ecommerce lists. Scrubby is an outbound instrument for B2B lists of uncertain provenance at ten times the price per address. A company running both a marketing list and a cold outbound motion could reasonably buy each for its own job.
Choose mailfloss if
Newsletter operators, ecommerce email marketers, and small businesses running a permission-based list inside a supported ESP, who want list hygiene to be a background process rather than a recurring manual chore, and who care about keeping mistyped subscribers rather than deleting them.
Choose Scrubby if
Cold outbound agencies and B2B sales teams whose lists are heavy with catch-all and gateway-protected domains, where a recovered contact is worth many multiples of a verification credit and where being wrong about deliverability costs a sending domain rather than an open rate.

13 attributes| Attribute | mailfloss | Scrubby |
|---|---|---|
| Category | Verification | Verification |
| Starting price | $29 per month for 10,000 credits, with a seven-day free trial (free plan available) | $47 per month for 6,000 credits, with 200 free credits on signup (free plan available) |
| Pricing model | Monthly or annual subscriptions priced by verification credits per month, with each tier carrying a volume selector, plus a separate one-time prepaid credit option with credits that never expire for teams on unsupported platforms or doing a one-off bulk clean. | Monthly credit subscriptions with rollover, a pay-as-you-go alternative with non-expiring credits, and a published enterprise volume ladder above 100,000 a month. Quick Verification costs one credit, Deep Verification three, and the same balance covers enrichment. |
| Free plan | No permanently free plan. The seven-day trial and the money-back guarantee are the risk-free paths. | 200 free credits on account creation, usable for verification or person and company enrichment. No recurring free allowance. |
| Free trial | Seven days on every subscription plan; a card is required but no charge occurs until day eight | No time-limited trial; 200 free credits with no credit card, plus a fourteen-day satisfaction guarantee on monthly plans |
| Best for | Newsletter operators, ecommerce email marketers, and small businesses running a permission-based list inside a supported ESP, who want list hygiene to be a background process rather than a recurring manual chore, and who care about keeping mistyped subscribers rather than deleting them. | Cold outbound agencies and B2B sales teams whose lists are heavy with catch-all and gateway-protected domains, where a recovered contact is worth many multiples of a verification credit and where being wrong about deliverability costs a sending domain rather than an open rate. |
| Setup time | Under a minute for the connection itself. OAuth from the dashboard, no API keys, no developer, and the vendor claims most platforms connect in under thirty seconds. The configuration that actually matters, deciding what gets deleted and what gets tagged, deserves rather longer. | Minutes for a bulk upload or API key, and the 200 free credits mean a first real test costs nothing. The only planning required is scheduling: a deep verification job needs 72 hours in the calendar before the send date. |
| Learning curve | Low. The four products map to obvious moments in a subscriber's life, and the settings are per connection rather than global. The only real thinking is around removal policy, because the system acts on your live list without asking. | Low on mechanics and moderate on policy. The credit model is simple, but deciding which addresses deserve a three-credit deep check and which are fine on a one-credit quick check is a judgement that determines your bill, and it takes a couple of lists to calibrate. |
| Platforms | Web dashboard, Native OAuth integrations with 40 ESPs and CRMs, Real-time API, Webhooks, JavaScript form widget, Google Sheets, Airtable, and Zapier extensions | Web application, REST API, CSV bulk upload, CRM cleaning integration, Free-standing testing tools |

Strengths and limitations
mailfloss
Strengths
- Typo repair across more than 250 patterns is a genuine differentiator with a direct revenue argument, and no other verifier profiled here treats it as a product.
- Forty native two-way OAuth integrations with per-connection rules, which turns list hygiene into a background process instead of a recurring CSV chore.
- The four-product lifecycle coverage, signup-time blocking, next-day sweep, and scheduled decay re-verification, is more complete automation than any other verifier here offers.
- Genuinely cheap entry at $29 a month, from a bootstrapped company that states low pricing as a principle rather than a promotion.
Limitations
- No catch-all resolution at all, which rules out B2B outbound work entirely.
- Subscription plans require one of forty supported platforms, and the fallback for everyone else is prepaid credits and manual CSV uploads, which is the exact workflow the product exists to eliminate.
- Poor value as a bulk cleaner: $209 a month for 125,000 credits against roughly $100 to $190 for a one-off clean of the same volume elsewhere.
- No permanently free tier, and the seven-day trial requires a card, which is less generous than the daily free credits at MyEmailVerifier and Verifalia.
Scrubby
Strengths
- Deep Verification is the only widely available method in this category that establishes deliverability by actually sending and watching for delayed bounces over 72 hours, rather than by inference.
- Quick Verification already covers catch-all and Secure Email Gateway protected domains in minutes at one credit, so the expensive mode is reserved for genuinely hard cases.
- Probing happens from Scrubby's infrastructure, so the reputation cost of testing hard addresses never touches your warmed sending domains.
- Credits roll over on monthly plans and never expire on pay-as-you-go, and the same balance covers person and company enrichment as well as verification.
Limitations
- Deep Verification sends real email to the addresses being checked, which is the exact practice BounceBan positions as a GDPR problem. Anyone with a strict legal or brand position on unsolicited contact should treat this as disqualifying rather than as a tradeoff.
- Latency: 24 hours for first deep results and 72 for final ones does not fit a same-day campaign, so deep checks must be planned into a schedule rather than run on demand.
- The most expensive credit in this profile set once the three-credit deep mode is in play, at an effective $0.015 to $0.024 per deep verification.
- No SOC 2, ISO 27001, or other third-party audit is published; the compliance story is a set of vendor statements.

Judge mailfloss on labour and retention, not on price per address. Per credit it is unremarkable, around $0.0017 to $0.0029, which is more than MyEmailVerifier or Truelist charge for a straight bulk clean. What you are buying is that the clean actually happens, every day, inside the platform where your contacts already live, with removals and tags written back automatically, and that mistyped subscribers are repaired rather than deleted. For a marketing team, the recurring cost of forgetting to clean, plus the acquisition spend wasted on deleted typos, plausibly exceeds the subscription. Two conditions have to hold for that to be true: your platform must be among the supported forty, and your list must be permission-based rather than cold. If either fails, mailfloss is the wrong shape and a bulk verifier at a third of the price does the job you actually have.
Scrubby
Monthly credit subscriptions with rollover, a pay-as-you-go alternative with non-expiring credits, and a published enterprise volume ladder above 100,000 a month. Quick Verification costs one credit, Deep Verification three, and the same balance covers enrichment.
- Starter$47
- Growth$97
- Pro$497
- Enterprise$0.008 to $0.004
Scrubby is the most expensive per-credit option profiled here once you use the mode you are actually paying for, and that is only defensible on a list where the risky segment is large and valuable. The arithmetic that matters is simple: if 30,000 addresses on a 100,000-row B2B list come back unknown from a conventional verifier, the question is what those 30,000 contacts are worth against a few hundred dollars of price difference. For an outbound agency selling five-figure contracts, it is not close. For a newsletter with a 2 percent accept-all share, paying $497 where MyEmailVerifier charges $99 buys nothing. The second consideration is not financial. Deep Verification sends real mail to real people to establish the answer, which is a method BounceBan explicitly refuses on GDPR grounds. If you can live with that, Scrubby offers the strongest evidence standard in the category. If you cannot, the price is irrelevant.
Editorial verdict on each
mailfloss
mailfloss solves a different problem from every other verifier in this category, and it solves it well. The others answer the question is this address valid. mailfloss answers the question why is nobody cleaning this list, and its answer is to connect natively to forty platforms, run four automations continuously across the whole subscriber lifecycle, and write every removal, tag, and typo correction straight back where your contacts already live. The Typo Fixer alone is a defensible reason to buy it, because repairing a mistyped address keeps a customer you paid to acquire and every competitor simply deletes them. It is cheap, it is bootstrapped, and it has been doing this since 2017. The boundaries are clear and worth respecting: no catch-all resolution, so B2B outbound teams should look elsewhere entirely, and no value as a bulk cleaner, since $209 a month buys volume that a one-off competitor cleans for less. If you run a permission-based list inside a supported ESP and list hygiene is nobody's actual job, this is the right purchase and $29 a month is not a serious sum.

InnovationScrubby has the most defensible answer in the category to the hardest question in the category, and it charges accordingly. Quick Verification already resolves catch-all and gateway-protected domains that most competitors surrender on, and Deep Verification goes further than anyone by actually sending, waiting, and reading the delayed bounces that make lists look clean right up until they are not. The company is real and disclosed in a way several catch-all specialists are not: a named founder, an EU entity, more than 25 staff, and a group parent. The two reasons to walk away are both firm. The price per resolved address is the highest here once the three-credit deep mode is in use, and the deep method involves a vendor sending unsolicited mail to your prospects, which is precisely the practice a serious competitor refuses on privacy grounds. Decide that question first. If the answer is yes, buy the 200 free credits' worth of evidence before anything else, and reserve deep checks for the addresses whose answer is actually worth $0.015.
