Email deliverability for travel companies
Where the addresses come from
- Booking flows, where one person enters addresses for a whole party.
- Price alert and deal signups, high volume and low commitment.
- Loyalty program enrollment, the cleanest and most durable source in the sector.
- Travel agent and partner lists, a business audience with ordinary B2B traits.
The booker is not the traveller
A family holiday is booked by one person who enters four addresses. Three of those people did not consent to anything, may not know their address was given, and one of them was typed from memory and is wrong.
So mailing a passenger list is a consent question before it's a delivery one. The addresses that bounce are most often the ones someone else typed.
Travel is also very seasonal. If you mail lightly for eight months and heavily in January, that spike lands on a list that's been sitting still.
What the results tend to look like
International and consumer-heavy. Expect European ISP domains, regional webmail and a long tail of rare providers. Coverage on a genuinely international list runs below a domestic one, because reach and rate limits vary by region rather than by effort.
What to do about it
Separate the booker from the passengers
One of them gave you an address on purpose. The others had theirs entered by somebody else, and only the first is a marketing contact.
Check before the January peak
Booking season is a volume spike on a list that has been idle, which is exactly the pattern receivers treat as suspicious.
Expect regional variation in what can be resolved
A list across twenty countries meets twenty sets of provider rules. Unresolved rates vary a lot by market.
Encode non-ASCII addresses properly at capture
International bookings bring accented letters into addresses. A form that mangles them makes addresses that fail before any server is asked.
Questions people ask
Can I market to everyone on a booking?
The booker gave you their address deliberately. The other passengers did not, and mailing them produces complaints from people who never signed up, which damages placement faster than bounces do.
Why does an international list resolve worse?
Provider mix. Regional providers throttle foreign connections in their own ways. Some can't be reached from outside their country at all.
When should a travel company check?
Ahead of the booking peak, so the volume ramp starts on a checked list rather than discovering the decay during your highest-value weeks.
