.it is the country domain used in Italy. Across 1,193,715 .it addresses verified by BounceZero between April and October 2026, 1.3% were invalid, 0.0% catch-all, 3.2% unknown and 64.2% confirmed valid. The verdicts are reliable and can be acted on directly.
Every .it address BounceZero verified for customers between April and October 2026, beside the corpus benchmarks. The remainder of each row to 100% is risky and role results.
| Segment | Addresses | Invalid | Catch-all | Unknown | Confirmed valid |
|---|---|---|---|---|---|
| .it | 1,193,715 | 1.3% | 0.0% | 3.2% | 64.2% |
| All non-freemail domains (business and ISP) | 6,514,884 | 14.5% | 2.3% | 27.0% | 32.6% |
| Business domains only (consumer ISP and freemail excluded) | 1,269,919 | 22.9% | 9.4% | 22.5% | 40.3% |
| All freemail | 1,415,154 | 17.6% | 1.1% | 2.1% | 74.0% |
Non-freemail includes consumer ISP mailboxes; a business-only cut is on the benchmarks page. Method and every other cut: Lead List Quality Benchmarks 2026. Risky and role on the .it row: 31.3%.
Italian gateways answer clearly, so .it has the lowest confirmed-invalid rate of any large country segment and few unknowns. Many .it addresses on lists are consumer ISP mailboxes.
Italian gateways answer verification probes clearly, so .it has the lowest confirmed-invalid rate of any large country segment and few unknowns. The segment is a mix of company domains and consumer ISP addresses such as alice.it, which is itself the second-largest domain in the corpus. Italy's regulator applies consent rules to individuals and sole traders, so the lawful basis depends on who owns the address more than on the verdict.
On confirmed-invalid rate, .it ranks 23 of 23 country domains in the corpus, just behind .se at 2.0%.
On unknown rate, .it ranks 22 of 23 country domains in the corpus, just behind .nz at 3.6%, ahead of .se at 2.9%.
On confirmed-valid share, .it ranks 3 of 23 country domains in the corpus, just behind .uk at 65.0%, ahead of .com at 59.7%.
How to read these rates: they are BounceZero's probe outcomes on customer lists over April to October 2026, not a census of .it mailboxes. Unknown and catch-all measure what verification could not confirm, which depends on the provider's gateway policy during the window as much as on the addresses. The lists are the ones customers chose to upload, so segments dominated by a few large uploads carry their age and source. Method and limitations: benchmarks page.
Unknown results are rare on .it: the gateway answers probes clearly, so a result you get is a result you can act on.
Only 1.3% of .it addresses hard-fail, against 14.5% across non-freemail domains.
Catch-all is negligible on .it (0.0%); when this provider does return valid, the mailbox accepted the probe itself rather than a blanket accept.
With 64.2% of addresses confirmed live, .it is a segment you can send to from the main domain without a second thought beyond re-verifying before every send.
Note the risky and role share: 31.3% of .it results landed there, which the four headline columns do not show. Read risky as 'deliverable but with a flag' and test it at low volume before trusting it.
Trust the verdicts. Apply consumer consent rules to ISP addresses; business .it domains can rest on legitimate interest.
Role addresses such as info@ and sales@ make up 0.1% of .it addresses in the corpus. Role addresses rarely reach a person; prefer named contacts.
1.3% of 1,193,715 .it addresses verified by BounceZero between April and October 2026 were confirmed invalid, against 14.5% across non-freemail domains and 17.6% across freemail.
3.2%. Unknown means the mailbox could not be confirmed either way, usually because the gateway deferred the probe. BounceZero refunds unknown results; on .it it is rare enough to re-check once and move on.
Not in practice: 0.0% of .it addresses returned catch-all, so a valid verdict means the mailbox exists.
64.2% confirmed valid at verification time. Keep bounces under 2% and complaints under 0.3% on the send, and re-verify the segment before every send.
