Scrubby vs Allegrow

Both sell an answer to the rows a normal verifier leaves as catch-all, and they get there by opposite routes. Scrubby's deep check sends a real message and reports back once the result is in, which takes days. Allegrow reads signals instead and sends nothing, and it sells that work as add-on credits on a monthly plan. You're choosing between waiting for a delivery result and paying a subscription for a read that sends nothing.

Where each one is stronger

What each vendor does that the other does not, stated as capability rather than advice.

Scrubby strengths

Scrubby gives you two depths. A quick check costs one credit. A deep check costs more and sends a real message to the address, with first results within a day and final ones after several days. That's a delivery result rather than a guess from signals. You can pay monthly or pay as you go, pay-as-you-go credits never expire, and new accounts get free credits. Data sits on AWS in US West.

Allegrow strengths

Allegrow reads catch-all addresses through a signal-based process with no test sends, so nothing goes out in your name while it works. It sells verification as $8 per 1,000 add-on credits on top of a monthly plan, from the $99 Starter up to Scale Plus Unlimited at $1,340 a month, read on allegrow.co on 24 September 2026. A free trial is listed on its plans page. It publishes an accuracy percentage from its own test on its site.

What separates Scrubby from Allegrow

Start with your deadline. If a campaign goes out tomorrow, a deep check that settles over several days won't be back in time, so look at Allegrow's signal read or Scrubby's quick check. If you're cleaning a cold list for next month, the wait costs you nothing and you get a result drawn from a real delivery. Our catch-all answer explains why these rows need a different method at all.

Then look at how you pay. Allegrow's $8 per 1,000 rides on a monthly plan from $99, so it makes sense if you'll use the plan's other features every month. Scrubby's pay-as-you-go credits never expire, which suits a team that tackles catch-alls in bursts. Price both at your own catch-all volume, not your whole list, since you only need them for that slice. What is a normal catch-all percentage? helps you size it.

Last, think about your sending domain. Scrubby's deep check sends a real message to each address, so ask where it sends from and how bounces are handled. Allegrow's method sends nothing. Both vendors publish an accuracy claim on their own sites; we don't print either figure, so read them there and test both on a slice of your own catch-alls.

What Scrubby and Allegrow both run into

Vendor accuracy percentages in this category count how often a returned verdict was right. They are calculated after the catch-alls and the servers that refuse to answer have left the denominator. Hunter tested 15 verifiers on 3,000 real business addresses (3 November 2025) and measured 31.2% to 70.0% overall. Both kinds of figure are real and they are not measuring the same thing.
