Can we email everyone who has ever stayed with us?

That depends on the consent obtained and the jurisdiction. Rules distinguish between transactional messages relating to a booking and marketing messages, and several markets — including Türkiye, with its national permission registry — impose specific requirements. This is a question for the property’s legal or data protection adviser rather than one to settle from an article.

Why is our open rate falling while the list keeps growing?

Usually because the list is growing faster than its relevance. Adding contacts without segmenting them means an increasing share receives messages that do not apply to them. Engagement declines before unsubscribes do, which is why list size can look healthy while reach is quietly collapsing.

Is email still worth the effort compared with paid channels?

For most hotels it is among the strongest performers per contact, because the audience already knows the property. Its limitation is scale: it reaches only people you have already met. It complements demand-generation channels rather than replacing them.

Email Marketing for Hotels

The only audience you own outright — and the one most hotels let go stale.

Email occupies an unusual position in a hotel’s channel mix. It is the only meaningful audience the property owns outright: no platform decides who sees it, no auction sets its price, and no algorithm change can remove it overnight.

It is also consistently among the highest-converting sources in published hotel benchmark data, sitting far above social and non-brand search. That is not because the emails are unusually persuasive. It is because everyone receiving them has already stayed with you or asked to hear from you.

The performance comes from the list, not the campaign.

A well-designed email to a stale, poorly segmented list will underperform a plain one sent to guests who recently stayed. Most attempts to improve email performance address the message when the constraint is the list.

In Short

Email is the only audience a hotel owns outright, and published benchmark data consistently places it among the highest-converting sources for hotel websites, well above social and non-brand search. That performance comes from who is on the list rather than from the design of the message: recipients have already stayed at the property or explicitly asked to hear from it. Two things determine whether the channel keeps working. The first is consent and compliance, which is a legal requirement rather than a best practice; regulations such as the United States CAN-SPAM Act govern accurate headers, honest subject lines and prompt handling of unsubscribe requests, and equivalent rules exist in most markets including a mandatory national registry in Türkiye. The second is segmentation, because a single message sent to every contact steadily trains recipients to ignore the sender, and the resulting decline shows up as falling engagement long before it shows up as unsubscribes.

Two things that erode the channel

Sending everything to everybody

The simplest way to run hotel email is to send every campaign to every contact. It is also the reliable way to destroy the list, because most messages will be irrelevant to most recipients.

The damage is gradual and easy to miss. People stop opening before they unsubscribe, so the list size looks stable while its actual reach falls. By the time unsubscribe rates move, engagement has usually been declining for months.

Basic segmentation prevents most of this: guests who have stayed against enquirers who have not, recent guests against dormant ones, and where relevant, the segment a guest belongs to — business, family, or leisure. None of this requires sophisticated tooling, only a decision to stop sending one message to everyone.

Treating consent as a formality

Commercial email is regulated. In the United States the CAN-SPAM Act sets requirements covering accurate header information, non-deceptive subject lines, a clear opt-out mechanism and prompt honouring of opt-out requests. Comparable regimes apply elsewhere, and in Türkiye commercial messages additionally run through a mandatory national permission registry.

The compliance risk is real, but the commercial risk is what usually bites first. A list built without genuine consent produces poor engagement, and poor engagement causes mailbox providers to filter the sender — including the transactional and pre-arrival messages the hotel genuinely needs delivered.

A hotel that treats consent seriously is therefore not only reducing legal exposure. It is protecting its ability to reach guests at all.

What makes hotel email actually work

Because the value sits in the list rather than the message, improving this channel means improving how the list is built, segmented and kept current.

Collect the address where intent is highest

The booking flow and the stay itself produce the most reliable addresses. A newsletter box in the footer produces the fewest.

Segment by relationship, not by campaign

Past guests, enquirers and dormant contacts want different messages. Sending them the same one degrades all three.

Make opt-out immediate and obvious

Prompt, frictionless unsubscribes are both a legal requirement and a way to keep the engaged portion of the list healthy.

Connect it to the booking system

Email that knows who has stayed, when, and in what room type stops being a newsletter and becomes a revenue channel.

Frequently Asked Questions

Frequency matters less than relevance. A property with genuine seasonal news might send monthly; one sending weekly with nothing to say will train recipients to ignore it. Watch engagement by segment rather than choosing a cadence in the abstract.
