The older Dutch Hotmail brand. Microsoft answers clearly, the invalid share is modest and half of addresses confirm valid. Compared with live.nl it has survived better because the accounts were migrated rather than retired.
Hotmail's Dutch regional domain predates live.nl and was migrated into Outlook.com rather than retired, which is why it has aged better than its sibling. The addresses belong to Dutch consumers and small business owners who opened the account in the early 2000s. Dutch law requires opt-in for individuals and permits legitimate-interest prospecting to companies with an opt-out; most hotmail.nl contacts fall on the consumer side of that line.

How to read these rates: they are BounceZero's probe outcomes on customer lists over April to October 2026, not a census of Hotmail Netherlands 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 Hotmail Netherlands: the gateway answers probes clearly, so a result you get is a result you can act on.
At 7.2%, Hotmail Netherlands loses fewer addresses to hard failures than almost any segment; the ones that fail are typos and closed accounts.
Catch-all is negligible on Hotmail Netherlands (0.0%); when this provider does return valid, the mailbox accepted the probe itself rather than a blanket accept.
50.3% of Hotmail Netherlands addresses confirmed as deliverable at verification time and can go straight to the primary sequence, with a re-check before every send.
Note the risky and role share: 33.8% of Hotmail Netherlands 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.
Reliable segment. Verify once, send to the confirmed-valid half, and re-check quarterly.
Role addresses such as info@ and sales@ make up 0.0% of Hotmail Netherlands addresses in the corpus. Role addresses are rare here, as expected for a mailbox provider.

The country segment Hotmail Netherlands belongs to
7.2% of 34,790 Hotmail Netherlands addresses verified by BounceZero between April and October 2026 were confirmed invalid, against 14.5% across non-freemail domains and 17.6% across freemail.
8.7%. Unknown means the mailbox could not be confirmed either way, usually because the gateway deferred the probe. BounceZero refunds unknown results; on Hotmail Netherlands it is rare enough to re-check once and move on.
Not in practice: 0.0% of Hotmail Netherlands addresses returned catch-all, so a valid verdict means the mailbox exists.
50.3% 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.
