Scrubby Alternatives for Catch-All Emails: Resolve, Grade or Send and Watch

If you are looking past Scrubby, the question is how much certainty you need on catch-all addresses, and how long you can wait for it. Scrubby's Deep Verification sends a real email to each address and watches for bounces over 72 hours, at 3 credits an address on plans from $47 a month for 6,000 credits (2,000 deep checks). Alternatives either resolve unknowns with an extra check and charge only for those (Truelist), grade catch-alls without confirming them (SimpleVerifier), or let you run the send-and-watch test yourself on a small slice. Each trades cost, speed and certainty differently.

Scrubby's terms, as of 2 November 2026

From Scrubby's pricing page, read 2 November 2026:

Plan	Price	Credits	Per 1,000 credits	Deep checks if used only for Deep
Starter	$47/mo	6,000	$7.83	2,000
Growth	$97/mo	15,000	$6.47	5,000
Pro	$497/mo	100,000	$4.97	33,333
Enterprise	Custom	Over 100,000/mo

The last two columns are arithmetic on the published prices.

• Quick Verification, 1 credit: "Confirms deliverability on standard, catch-all, and SEG-protected domains in minutes."
• Deep Verification, 3 credits: "We send real emails to every address and observe how mail servers respond over 72 hours." First results in 24 hours, final in 72.
• Free credits: "Start free with 200 credits", no card.
• Rollover: on monthly plans, "unused credits roll over to the next month" while the subscription is active.
• Refunds: "All purchases are final. We don't offer refunds for unused credits, partial billing periods, or dissatisfaction with results."

So deep-checking 1,000 catch-all leads costs about $23.50 on Starter, or about $15 on Pro, and takes up to three days.

The four ways to handle catch-alls

A catch-all domain accepts every address during an SMTP check, so a mailbox can't be confirmed by asking. Every option works around that one way or another. Our catch-all methods comparison goes through each in detail; in short:

Method	Who	Cost per catch-all	Speed	What you get
Send and watch	Scrubby Deep	3 credits	24-72 hours	A result based on how servers responded to a real message
Resolve	Truelist enhanced resolution	3 credits, only on unknowns	Not stated	A verdict where it can resolve one
Grade	SimpleVerifier	Nothing extra	With the rest of the list	Risky, with higher, medium or lower likelihood and reasons
Do it yourself	Your own inbox	Your sending budget	3+ days	Real bounces from your own campaign

Truelist's terms are from its pricing page (read 2 November 2026): enhanced catch-all resolution is "applied only where standard returns 'unknown'" at 3 credits per resolved address, with credit packs from $1.40 per 1,000. Our Truelist alternatives post covers the rest of its pricing.

Things to ask any send-and-watch service

Sending a real message to your prospect's mail server is a different act from an SMTP check, so ask:

• What does the message say, and from which domain? If it lands, a person or their security team may see it.
• Can the recipient see it? Some services send messages designed not to be read, but a gateway may still log or quarantine them.
• What counts as "deliverable"? No bounce after 72 hours is weaker evidence than it sounds. Some gateways and Microsoft 365 tenants accept and then silently drop mail, or never return bounces.

None of this makes send-and-watch wrong. It's the only method that tests the path a real email takes. But know what you are buying.

The cheaper alternative: grade, then test the slice yourself

For most cold email lists, catch-alls are a slice, not the whole list. A low-cost setup:

1. Verify everything with a standard check. Valid rows go into the main campaign.
2. Grade the catch-all slice. SimpleVerifier returns each catch-all row as risky with a higher, medium or lower likelihood and the reasons, using signals from your list. The catch-all scoring page lists every signal and the ones we tested and rejected. We never mark a catch-all address valid.
3. Send step 1 to the higher-likelihood rows in their own campaign, from a healthy inbox at low volume, and wait at least three days for late bounces before step 2. Our post on catch-all leads in sequences covers the timing.
4. Pay for resolution or send-and-watch only on the leads worth it, such as named accounts in an ABM list.

This costs your own sending budget instead of credits, so watch your bounce rate. Our bounce budget post turns provider limits into bounce counts per inbox. Grading is cheaper and faster than Scrubby, and gives you less certainty. Be honest with yourself about which you need.

We haven't run an accuracy test on Scrubby, Truelist or any other vendor, and we don't publish accuracy figures for ourselves. To compare, take 300-500 catch-all rows, run them through each option, send only what each calls good, and count real bounces. Our bench test guide has the method.

When Scrubby is the right call

• Catch-alls are most of your list, for example enterprise targets behind Proofpoint or Mimecast.
• Each lead is valuable enough that 3 credits and three days is cheap.
• You want the verifier to carry the send-and-watch risk, not your own inboxes.

When an alternative fits better

• Catch-alls are under about 15% of the list.
• You need results the same day.
• You want to try before committing, since Scrubby's purchases are final.

Where SimpleVerifier fits

Grading is included in every check. Upload a list on the verify page and see your catch-all share and grades; the first 100 checks are free with a Google sign-in. Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off. See pricing.
