Truelist alternatives
If you're shopping for a Truelist alternative, the Enhanced pass is probably why. Here's what the same list returns and costs on ZapBounce, where catch_all is billed once and unknown is never billed.

Why people look elsewhere
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 prices by volume band, with the per-1,000 rate falling as the file grows, and sells Unlimited monthly plans for heavy senders. The Enhanced pass on hard rows costs extra credits on top. ZapBounce prints one ladder, $25 for 10,000, $139 for 100,000 and $949 for a million, and a catch_all row costs one credit, once.
What ZapBounce changes for a Truelist user
The differences that show up on the first invoice and the first results file.
The short version
- 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.
Before you move off Truelist
Run the same sample through two vendors and the interesting number is not how many came back valid.
Add up last quarter's Enhanced passes
Pull the credits you spent on the second pass for catch-all and unknown rows. Set that total beside one credit per catch_all row and zero for every unknown.
Map your code to four results
ZapBounce returns valid, invalid, catch_all or unknown, plus flags for role, disposable and free-provider addresses. Check your branching logic handles each one.
Choose a retention window per key
Decide how long each integration should keep results, from deleted on download to 90 days. Set it on the key before the first upload.
Re-run one known list as a baseline
Send a list Truelist already checked through ZapBounce and compare the catch_all and unknown counts. The difference tells you what the Enhanced pass was buying.
What switching actually involves
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.

Questions about moving off Truelist
Is there a Truelist alternative with no unlimited plan to manage?
ZapBounce sells credits that never expire, from $5 for 1,000 to $949 for a million, so you buy for the list in front of you. A monthly plan is there too, at 15% less than the same credits pay-as-you-go.
Can I switch from Truelist without changing my integration code much?
Yes. Swap the endpoint and key for ZapBounce's POST /v1/verify, and branch on four results: valid, invalid, catch_all and unknown. The reason and the literal SMTP code come back on every row.
Why do people leave 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.
How hard is it to switch verifiers?
For bulk cleaning, no harder than uploading the file somewhere else. For real-time checks on a signup form it is an API swap, which is an afternoon.
Total what the Enhanced pass cost you last quarter. On ZapBounce the same rows cost one credit each, or nothing when the server never answered.
