Verified travel leads are contacts in the travel trade, travel agencies, tour operators, destination management companies, hotels and corporate travel buyers, or travellers themselves, sold with a claim that the contact details were checked. The claim usually means a check at the time the record was built, which can be months before you buy. In the BounceZero corpus, bought lists not verified in the last 90 days benchmark at about one invalid address in seven, and travel-heavy country domains such as .au run far worse at 36.5% invalid.
Four products share the name. Only two of them are B2B lists you can sample and verify.
Agencies, tour operators, DMCs, hotel groups, airline and cruise sales teams, corporate travel managers. Sold by data brokers and trade-show organisers. Company domains plus a large freemail share among small agencies. Verifiable.
Hotels, attractions, transfer companies, by destination. Often scraped from booking sites and directories. Role addresses dominate (reservations@, info@). Verifiable, but expect to discard most role rows.
Individuals who requested a quote or filled a form, sold per lead, sometimes shared across several buyers. Consent and recency are the whole value; a shared lead is contacted by five agencies in an hour.
Live transfers or real-time form fills. Not a list; priced per contact and judged on close rate, not deliverability.
Travel is a geographically spread trade, and country domain sets the bounce profile more than the vendor does. BounceZero corpus, April to October 2026.
| Where the contacts sit | Corpus segment | Invalid | Catch-all | Unknown | Confirmed valid |
|---|---|---|---|---|---|
| International agencies and operators | .com | 16.4% | 4.4% | 14.7% | 59.7% |
| UK agencies | .uk | 17.0% | 3.7% | 10.6% | 65.0% |
| Australian agencies | .au | 36.5% | 6.3% | 17.6% | 37.3% |
| New Zealand agencies | .nz | 28.9% | 0.1% | 3.6% | 11.6% |
| UAE and Gulf operators | .ae | 10.8% | 1.8% | 14.9% | 47.7% |
| French operators | .fr | 12.1% | 0.5% | 9.3% | 47.6% |
| Italian operators | .it | 1.3% | 0.0% | 3.2% | 64.2% |
| Small agencies on freemail | Freemail | 17.6% | 1.1% | 2.1% | 74.0% |
Australia and New Zealand are the two markets where a "verified" travel list is most likely to disappoint. Full cuts: Lead List Quality Benchmarks 2026.
A seller's "verified" usually means one of three things: the record passed a syntax and domain check when it was compiled, an SMTP probe succeeded at some point, or a human confirmed the business exists. None of those says the mailbox works today. Travel is seasonal and small agencies close or change hands often, so the gap between compiled and bought is where the bounces come from.
Your definition should be narrower: the address returned valid from a verifier within the last 90 days, catch-all and unknown are labelled separately, and role addresses are flagged. Ask the seller for the verified-at date per record. If there is no date, the list is unverified whatever the label says.
The third thing to ask is how many rows are role addresses. Hotel and supplier lists scraped from booking sites run heavy with reservations@ and info@. They verify, they reach a desk, and they do not reach the owner or the revenue manager.
Same country, same business type you will buy. A sample the seller picks is not random; ask for rows by a rule, such as every 50th record.
The free tier covers 100 checks a month; a Starter pack covers 2,000 for $6. Record invalid, catch-all, unknown and role separately.
Better than the corpus rate for that country is a good list for that market. Worse means the list is older or scraped. For .au and .nz, anything under 25% invalid is unusually good.
Divide the quoted price by the confirmed-valid rows you will get, not the row count. A $500 list of 5,000 rows at 40% confirmed costs $0.25 per reachable contact.
Full verification through a bulk job. Cold sequences to confirmed valid only; catch-all and unknown to phone or a warm sequence; role addresses used to find a named contact.
Emailing an agency, operator or hotel about a relevant business service can rest on legitimate interest in the UK and EU, with the source named and an opt-out offered, and on CAN-SPAM in the US. Sole-trader agents on freemail deserve the more careful treatment given to individuals.
Consumers need consent under PECR and GDPR, and a shared or resold consumer lead rarely carries consent that extends to you. In the US, telephone follow-up is subject to TCPA and do-not-call rules. Buy consumer travel leads only from a source that can show the consent record, and never email a consumer list of unknown origin.

Trade contact lists come from data brokers, trade-show organisers and directories; consumer leads from quote platforms and lead marketplaces. Whoever sells it, ask for a random 200-row sample in your segment and the verified-at date per record, verify the sample yourself, and price the list on confirmed-valid rows.
Usually that the record passed a check when it was compiled, which can be months before purchase. Your standard should be a verifier result of valid within 90 days, with catch-all, unknown and role flagged separately. If the seller cannot give a verified-at date, treat the list as unverified.
In the 2026 corpus, .au addresses ran 36.5% invalid and 6.3% catch-all, the worst of any major market, driven by ISP mailbox churn and old scraped records. A .au travel list that verifies under 25% invalid is unusually good; most need heavy cleaning.
Consumers need consent, and a resold lead rarely carries consent that extends to a new buyer. UK PECR, EU GDPR and US TCPA rules apply. Buy consumer travel leads only where the seller can show the consent record, and prefer trade contacts for cold email.
Price per reachable contact, not per row. Verify the sample, take the confirmed-valid share, and divide the quoted price by the rows that share implies. Lists that look cheap per row are often dear per contact once a third of the rows are dead or role addresses.
Verify 200 rows from the seller's list, see invalid, catch-all, unknown and role separately, and buy on the real number. 100 free checks a month, unknowns refunded.
