.br is the country domain used in Brazil. Across 8,450 .br addresses verified by BounceZero between April and October 2026, 15.3% were invalid, 12.7% catch-all, 12.0% unknown and 58.5% confirmed valid. Catch-all and unknown together mean a large share cannot be confirmed.
Every .br 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 |
|---|---|---|---|---|---|
| .br | 8,450 | 15.3% | 12.7% | 12.0% | 58.5% |
| 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 .br row: 1.6%.
A mixed consumer and business segment with moderate invalid rates; Brazilian lists often carry freemail addresses rather than .br domains.
Brazilian B2B lists carry more freemail than .br company domains, because small businesses in Brazil commonly use Gmail or Hotmail. The .br domains that do appear verify at moderate rates. Brazil's LGPD requires a lawful basis for processing and consent for most marketing to individuals, so the freemail share of a Brazilian list is a consent segment and the company-domain share the prospecting segment.
On confirmed-invalid rate, .br ranks 13 of 23 country domains in the corpus, just behind .ca at 15.9%, ahead of .de at 13.8%.
On unknown rate, .br ranks 17 of 23 country domains in the corpus, just behind .ca at 13.8%, ahead of .uk at 10.6%.
On confirmed-valid share, .br ranks 6 of 23 country domains in the corpus, just behind .fi at 59.6%, ahead of .nl at 54.6%.
How to read these rates: they are BounceZero's probe outcomes on customer lists over April to October 2026, not a census of .br 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.
About one in 8 .br addresses cannot be confirmed either way. That is gateway behaviour, not a verdict; route those contacts to phone or LinkedIn and re-check after a week.
.br runs at 15.3% confirmed invalid, ordinary for a list that has not been checked in a while; the failures are closed mailboxes and should be removed.
Catch-all is the defining trait here: 12.7% of .br addresses accept anything, so finder guesses look valid and bounce later. Hold them out of cold sequences entirely.
58.5% of .br addresses confirmed as deliverable at verification time and can go straight to the primary sequence, with a re-check before every send.
Verify at import; LGPD applies and consent is required for individuals.
Role addresses such as info@ and sales@ make up 1.3% of .br addresses in the corpus. Role addresses rarely reach a person; prefer named contacts.
15.3% of 8,450 .br addresses verified by BounceZero between April and October 2026 were confirmed invalid, against 14.5% across non-freemail domains and 17.6% across freemail.
12.0%. Unknown means the mailbox could not be confirmed either way, usually because the gateway deferred the probe. BounceZero refunds unknown results; re-check after a week or use a second channel.
Partly: 12.7% of .br addresses sat behind a catch-all accept, so the server took any address and the mailbox could not be confirmed.
58.5% 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.
