Spaw vs Emailable
Emailable is an email verification service with pay-as-you-go credits, a bulk verifier, a widget and an API, with Node.js, Ruby and Python libraries.
The table uses Emailable's public pricing and documentation pages as checked on 2026-09-13, and Spaw's own pricing page. A row those pages carry no value for is marked "not on the pages read" rather than guessed at, and that is a statement about the reading and not about what Emailable publishes.
| spaw | emailable | |
|---|---|---|
| Pricing model | Pay-as-you-go credit packs whose credits never expire, or optional plans, billed monthly or yearly, that deposit the same credits every month for less and roll unused plan credits over up to three months' allowance; both through Stripe Checkout | Pay-as-you-go credits that never expire, or a monthly subscription at a 15% discount; minimum purchase 5,000 credits |
| Free tier | 100 free credits every month, no card required | 250 free credits at signup |
| Price per 1,000 at about 10k | $7.80 (Growth pack: 5,000 credits for $39), or $5.80 on the Growth monthly plan (5,000 credits for $29 a month) | $7.60 (the pay-as-you-go rate printed for the 5,000-credit package, $0.0076 a credit; larger packages are priced in a calculator, and the 5,000-credit subscription is $32.30 a month after the 15% discount) |
| Price per 1,000 at about 100k | $4.49 (Volume pack: 100,000 credits for $449), or $3.49 on the Volume monthly plan (100,000 credits for $349 a month) | not on the pages read |
| Unknown or catch-all results billed | No: an unconfirmed mailbox (reason unverified) and an answer Spaw could not obtain because its handshake partner was unavailable are free and leave no 7-day repeat marker, so a later lookup is a fresh one; a catch-all answer costs 1 credit like any risky answer, and an automatic re-check bills 1 credit only when it confirms the mailbox | No |
| Undeliverable results billed | No, within a fair use: undeliverable answers that needed a mailbox probe are free up to max(500, your billed email answers) in a rolling 30 days, then 1 credit each; the rest are always free | Yes |
| SMTP mailbox check | Yes | not on the pages read |
| Catch-all handling | A catch-all answer is remembered per domain for 7 days, and every unconfirmed mailbox carries a published 0 to 100 mailbox_confidence estimate | Returns an accept_all flag with the result; unknown results and duplicates are refunded |
| Bulk limit | 100,000 addresses per bulk job, with an HMAC-signed completion webhook | Lists of any size; about 10,000 addresses processed in 2 to 3 minutes |
| Batch API | 50 addresses per synchronous request, probes sent concurrently | not on the pages read |
| Rate limit | 5 requests per second per key on the email and consistency endpoints | not on the pages read |
| Official SDKs | Python, Node.js, PHP | Node.js, Ruby, Python |
| Data retention | Only email verification keeps a history row, for 30 days, then pruned; test addresses are never logged | All data is deleted after 30 days |

Questions
Does Spaw charge for catch-all or unknown results?
Spaw bills per answer, not per probe outcome. A catch-all domain comes back risky with reason catch_all and costs 1 credit like any risky answer. A mailbox the handshake could not confirm (greylisting, a timeout, no definite answer) comes back risky with reason unverified and is free, and so is an answer Spaw could not obtain at all because its handshake partner was unavailable; neither leaves a 7-day repeat marker, so a later lookup is a fresh one (an uncertain result is reused for up to 15 minutes, then the mailbox is asked again) and bills 1 credit only once the mailbox is confirmed, and the automatic re-checks behind callback_url bill 1 credit only when they confirm it. Undeliverable verdicts are free within a fair use of max(500, your billed email answers) in a rolling 30 days, and invalid input and repeats within 7 days are free too. Emailable states that it does not bill unknown results.
Can I move a list from Emailable to Spaw?
Yes. Upload the CSV to the dashboard or POST it to the bulk endpoint; Spaw keeps your columns, adds the verdict columns, and lets you download only the deliverable, risky or undeliverable rows. Addresses that come back undeliverable join your suppression list so later runs skip them for free.
Is there a free tier?
Every Spaw account receives 100 free credits at the start of each month with no card on file, and unused free credits accumulate. Emailable offers: 250 free credits at signup.
