Is ZapBounce more accurate than Truelist?

Compare coverage before accuracy. On accuracy, Truelist's entry reads: None stated on its pricing page. Vendor accuracy claims in this market are calculated after unknown and catch-all addresses leave the denominator. ZapBounce reports coverage, the share of the list with a definite verdict, so the rest is visible, labeled and never billed.

Why switch from Truelist to ZapBounce?

One price per address at every depth. A catch_all row costs one credit, billed once, with no second pass to buy. Unknown results and duplicate rows are never charged, and the pricing page says so. Published prices on one page: $5 for 1,000, $25 for 10,000 and $139 for 100,000. Retention you set per API key, from 0 days (deleted on download) to 90, with 30 as the default. Our own SMTP check on port 25, closed before DATA, so no message reaches the addresses you check.

ZapBounce vs Truelist

Truelist's pitch is a low first-pass rate and an Enhanced pass you pay extra for on the catch-all and unknown rows. ZapBounce bills one credit per address, labels catch-alls from a single probe, and never bills an unknown. So the comparison turns on what the hard rows cost you.

Moving off Truelist

The Enhanced pass is where Truelist bills grow. The first check is cheap, then the catch-all and unknown rows get offered a second, extra-credit pass, and on a B2B list that slice isn't small. People start comparing when they add up what the second pass cost.

Truelist and ZapBounce both take a CSV upload or an API call, so the switch is an endpoint and a key. Point your signup form or your enrichment step at ZapBounce's API, re-run your last list as a baseline, and keep the Truelist export beside it to compare the catch_all and unknown counts.

The hard addresses, and how they come back

Catch-alls, Yahoo, cloud blocks and traps

An accept-all server says 250 to every recipient, real or random. ZapBounce proves it with one probe at the same domain, returns the row as catch_all, bills one credit and stops. There's no second pass to buy.

Truelist offers an Enhanced pass on catch-all and unknown rows for extra credits (truelist.io/pricing, read 24 September 2026). On ZapBounce the unknown rows come back with the reason attached and are never billed, so a second look costs nothing.

Yahoo and AOL accept every recipient on purpose, and Gmail and Microsoft 365 throttle probes from cloud ranges. ZapBounce returns those rows as unknown and counts them in coverage on every file.

Pristine spam traps look like working mailboxes on the wire, and no pass at any price flags one. Keep your sign-up sources clean and those rows never arrive.

Questions people ask about Truelist

Does ZapBounce charge extra for catch-all emails like Truelist's Enhanced pass?

No extra charge. ZapBounce bills a catch_all row one credit, once, after a single probe to a random address at the same domain. Unknown rows are never billed, so there's no second pass to pay for.

Why does the table show no Truelist prices?

This site prints a competitor price only once it's on our dated competitor record, so Truelist's figures are left for its own pricing page. ZapBounce's are fixed: $5 for 1,000, $25 for 10,000 and $139 for 100,000.

How long does ZapBounce keep my list compared with Truelist?

ZapBounce keeps uploads and results for 30 days by default, and you can set each API key from 0 days (deleted on download) to 90. Any batch can be deleted at once with DELETE /v1/batches/{id}.
