Real estate leads are prospective buyers, sellers, landlords or tenants whose contact details an agent acquires to start a conversation, either by generating them or by buying them from portals, networks, brokers and data compilers. Unlike B2B lists, property leads are mostly personal mailboxes: in BounceZero's 2026 corpus, gmail.com addresses verified 96% valid while Australian ISP mailboxes ran 30 to 93% invalid, so where the lead lives decides whether it can be reached.
A B2B file is mostly company domains with a predictable pattern. A real estate file is mostly consumers on gmail.com, outlook.com, iCloud and whatever the local ISP hands out, plus a layer of agents, brokers and developers on business domains. The consumer layer is either very clean or very dead depending on provider, and the age of the file decides which.
That changes the maths. A seller lead from a portal is worth hundreds of pounds of commission and arrives fresh; a farming list of homeowners bought from a compiler may be three years old and half unreachable. The vendors below sit at different points on that line, and the data tables show what each delivers once verified.
Prices are vendor-reported 2026 ranges and vary widely by market. The last column is what verification of the delivered addresses typically shows.
| Source | What you get | Cost (vendor-reported) | Exclusive? | Address quality |
|---|---|---|---|---|
| Portal leads (Zillow, Realtor.com, Rightmove, Domain) | Buyer or seller enquiry on a listing, routed to you | $20 to $500 per lead, or a share of commission | Usually shared with 2 to 5 agents | Fresh; 5 to 10% typos and throwaways |
| Pay-per-lead networks | Form fills from comparison and valuation sites | $15 to $200 per lead | Shared unless you pay a premium | Fresh; same typo rate; higher "just curious" share |
| List brokers | Homeowner, landlord, investor or expired-listing files by area | $0.05 to $0.40 per record | No | 15 to 40% invalid depending on age |
| Farming and public record compilers | Property records joined to contact data | $0.02 to $0.20 per record | No | 20 to 45% invalid; many role and ISP addresses |
Agent-to-agent and developer lists are B2B and behave like the files on the B2B list buying page.
Consumer and ISP providers from the BounceZero corpus, April to October 2026. These providers make up most of the addresses in homeowner and tenant files in their markets.
| Provider | Market | Verified | Invalid | Catch-all | Unknown | Valid |
|---|---|---|---|---|---|---|
| gmail.com | Global | 801,225 | 3.5% | 0.0% | 0.0% | 96.0% |
| hotmail.com | Global | 253,445 | 16.5% | 0.1% | 0.0% | 70.5% |
| icloud.com | Global | 50,895 | 73.0% | 0.0% | 4.9% | 20.0% |
| aol.com | US | 33,275 | 17.9% | 24.7% | 19.9% | 11.0% |
| att.net | US | 421,292 | 10.1% | 0.0% | 26.4% | 5.8% |
| bellsouth.net | US | 134,384 | 4.6% | 0.1% | 43.7% | 15.5% |
| bigpond.net.au | Australia | 35,207 | 8.0% | 0.0% | 87.0% | 0.3% |
| tpg.com.au | Australia | 246,811 | 30.1% | 8.9% | 5.1% | 53.9% |
| hotmail.com.au | Australia | 110,452 | 92.7% | 0.0% | 3.1% | 2.3% |
icloud.com's 73% reflects the lists people upload, which skew old; Apple mailboxes themselves are not unusually dead. US legacy ISPs (att.net, bellsouth.net) refuse probes, so expect unknowns, not bounces. Full tables: benchmarks.
Gmail-heavy files are clean. Files from older homeowners carry aol.com, att.net and bellsouth.net, where a quarter to half of rows come back unknown. Send to those at low volume from a secondary domain, or call instead.
Mostly gmail.com, hotmail and outlook.com; .uk business domains for agents verify 65% confirmed valid with 17% invalid. The weak spot is BT and Sky legacy mailboxes in older files.
The hardest market in the corpus. hotmail.com.au is effectively dead, bigpond.net.au cannot be probed, tpg.com.au loses a third. An Australian homeowner file older than a year is mostly unreachable by email; verify before paying anything.
For farming and broker files, a date per row. Over 12 months on consumer mailboxes means expect 20% or more gone. Price accordingly or decline.
Not the vendor's showcase. Verify them. Under 8% invalid and no spam-trap flags is a usable file; over 15% is not.
Homeowners are individuals. In the UK and EU, cold email to individuals needs consent under PECR and GDPR; post and phone have different rules. In the US, CAN-SPAM allows it with an opt-out. The vendor must show where consent came from.
info@ and office@ rows in a residential list are compiler noise. Agents belong in a separate segment with a different message.
Bulk verification labels valid, invalid, catch-all and unknown per row. Unknowns on US and Australian ISPs are real people the server will not confirm; do not treat them as valid.
Real estate has the advantage that phone works. Route unconfirmed addresses to calls or SMS instead of risking the sending domain.
Consumer mailboxes churn too. A pass before every send keeps the bounce rate under the 2% line that sending platforms enforce and that Gmail and Microsoft enforce.
Fresh data, different risks.
A buyer who mistypes their Gmail address is a lead you will lose on the first follow-up. Validating through the real-time API on the form, or on the lead feed, flags typos while the person is still reachable by phone.
Shared portal leads go to several agents at once. Speed of first contact decides the outcome; if you cannot respond inside five minutes, pay for exclusivity or do not buy.
Wrong numbers, duplicates and out-of-area leads should be returnable. Networks that will not take returns have priced junk into the rate.
A $300 exclusive seller lead that closes one in eight beats a $30 shared lead that closes one in a hundred. The per-lead price is the wrong number to optimise.
For investor, landlord and developer segments, the B2B route works: company registries, portal listings and LinkedIn give you names, a finder gives you an address, a verifier confirms it. The cold email for real estate guide covers the sequences, and the agency version covers outreach to other agencies.
For homeowners, buying is usually unavoidable, because consent rules and the absence of public email records mean there is no clean way to build the file. That makes the sample test the whole game: it is the only moment you can decline.

Four places: property portals that route buyer and seller enquiries to agents, pay-per-lead networks built on valuation and comparison sites, list brokers selling homeowner and investor files by area, and public-record compilers who join property data to contact data. Portals and networks sell fresh intent at a high price per lead; brokers and compilers sell cheap files that need verification before any send.
Vendor-reported 2026 ranges run from $20 to $500 per portal lead, $15 to $200 per network lead, five to forty cents per broker record and two to twenty cents per compiled record. Fresh intent costs a thousand times more per row than a compiled file, and usually earns it.
Exclusive portal and network leads with fast follow-up usually are; shared leads with slow follow-up usually are not. Broker and compiler files are worth it only when a sample verifies under 8% invalid and the consent basis is documented. Australian consumer files older than a year rarely pass.
In the US, yes under CAN-SPAM with identification and an opt-out. In the UK and EU, individuals need consent for marketing email under PECR and the ePrivacy rules, so a bought homeowner file is usually usable for post and compliant calls, not cold email, unless the vendor can show consent. Agents and developers at business addresses follow B2B rules.
Consumer mailboxes churn, legacy ISP addresses get abandoned, and compiled files are old. In the corpus hotmail.com.au was 92.7% invalid and bigpond.net.au 87% unconfirmable, while gmail.com was 96% valid. Verify the file, send to confirmed addresses, and call the rest.
Homeowner, investor or agent lists: upload, get valid, invalid, catch-all and unknown per row, and route the unknowns to the phone. 100 free checks a month.
