PeoplePC is a Legacy US ISP mailbox (EarthLink). Across 25,971 PeoplePC addresses verified by BounceZero between April and October 2026, 5.6% were invalid, 0.0% catch-all, 85.8% unknown and 2.5% confirmed valid. Unknown dominates because the gateway defers probes.
Every PeoplePC 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 |
|---|---|---|---|---|---|
| PeoplePC | 25,971 | 5.6% | 0.0% | 85.8% | 2.5% |
| 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 PeoplePC row: 6.1%.
A dial-up era EarthLink brand. The gateway defers almost everything, so the unknown share is above eight in ten and confirmed valid is close to zero. Almost every peoplepc.com address on a list is a relic.
PeoplePC was a low-cost dial-up brand that EarthLink acquired in 2002, and its mailboxes have been maintained on EarthLink's infrastructure since. The gateway defers nearly all probes, so verification cannot clear the segment, and the brand's age means the dormant share is high. Any list where peoplepc.com appears in volume was compiled from records old enough that the rest of the file deserves the same suspicion.
On confirmed-invalid rate, PeoplePC ranks 22 of 29 providers in the corpus, just behind iPrimus at 5.8%, ahead of SBCGlobal at 4.6%.
On unknown rate, PeoplePC ranks 3 of 29 providers in the corpus, just behind EarthLink at 86.9%, ahead of iiNet at 65.5%.
On confirmed-valid share, PeoplePC ranks 25 of 29 providers in the corpus, just behind AT&T at 5.8%, ahead of Hotmail Australia at 2.3%.
How to read these rates: they are BounceZero's probe outcomes on customer lists over April to October 2026, not a census of PeoplePC 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.
PeoplePC defers the majority of probes, so unknown dominates. Plan the segment around a warm, low-volume send from a secondary domain and let the bounce report decide.
Confirmed invalid is low at 5.6%, better than the business-list average of 14.5%.
Catch-all is negligible on PeoplePC (0.0%); when this provider does return valid, the mailbox accepted the probe itself rather than a blanket accept.
Confirmed valid is 2.5%. Send to that slice from the primary domain and treat the rest of the PeoplePC segment as unreachable by cold email.
Do not re-check. Keep any confirmed-valid address, drop the rest from sequences, and read the domain's presence as a list-age warning.
Role addresses such as info@ and sales@ make up 0.0% of PeoplePC addresses in the corpus. Role addresses are rare here, as expected for a mailbox provider.
5.6% of 25,971 PeoplePC addresses verified by BounceZero between April and October 2026 were confirmed invalid, against 14.5% across non-freemail domains and 17.6% across freemail.
85.8%. 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.
Not in practice: 0.0% of PeoplePC addresses returned catch-all, so a valid verdict means the mailbox exists.
2.5% 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.
