Email marketing and remarketing for boutique hotels in Ibiza (the GDPR-compliant way)
Email marketing and remarketing are the most cost-effective tools a boutique hotel has for bringing this summer's guests back next year and for winning back people who looked at your website and left without booking. In Ibiza, where six months of season are followed by months of quiet, they are also how you stay on your guests' minds through the winter.
They have to be done properly. Your hotel is in Spain, so EU GDPR and Spain's e-commerce law, the LSSI, decide what you can send, to whom and how, whatever your own nationality or your guests'. This guide explains the rules without the drama, then covers building your list, the emails a boutique hotel needs and remarketing that doesn't stalk anyone around the internet.
Why email and remarketing matter so much for a boutique hotel
A small hotel can't outspend a chain or an OTA on advertising. Where it can win is the relationship: you know the guest, the room they loved and when they came. Email turns that knowledge into commission-free direct bookings, and remarketing brings back the person who was halfway through your booking engine before getting distracted by another tab.
Both depend on one thing: data you obtained lawfully and are allowed to use for that purpose. So that's where we start.
The legal bit first: GDPR, LSSI and cookies
If you've run a business in the UK, you may know the "soft opt-in" from the PECR rules. Spain has its own version. Article 21 of the LSSI bans promotional emails that weren't requested or expressly authorised, but section 2 makes an exception: where there is a prior contractual relationship, you obtained the email lawfully and you use it to promote your own products or services similar to those the customer bought, you may write to them, provided you offered a simple, free way to object when you collected the data and in every message. GDPR adds that, where you rely on consent, you must be able to prove you obtained it.
| Situation | Can you email them offers? | What you need |
|---|---|---|
| Guest who booked directly with you | Yes, for services similar to what they booked | An opt-out offered when you collected the email and an unsubscribe link in every send |
| Guest who booked through an OTA | With express consent | Ask during the stay and keep a record |
| Website subscriber | Yes, if they signed up | Unticked box, clear wording, record of date and source |
| Website visitor for remarketing | Not email: this is advertising cookies and pixels | Consent in your cookie banner before any pixel loads |
On cookies, the Spanish data protection authority (AEPD) requires that if your banner has an accept button, it has an equivalent reject button on the first layer. Meta pixels and Google remarketing tags are advertising cookies, so they shouldn't fire until the visitor accepts. One more detail that's easy to miss: your email platform, CRM and booking engine process guest data on your behalf, so GDPR requires a data processing agreement with each of them. Reputable providers include one in their terms; make sure it's in place. None of this is legal advice; if your situation is unusual, speak to a data protection specialist in Spain.
What about WhatsApp?
Plenty of Ibiza guests would rather WhatsApp you than email, and that's fine for service: questions, arrival times, dinner reservations, transfers. But LSSI article 21 doesn't only cover email; it covers any "equivalent electronic communication". Sending offers by WhatsApp to someone who only messaged you about parking needs the same safeguards as a marketing email. If you want to use it for promotions, ask for specific permission for that channel.
Building your list without buying one
Bought lists don't work: you have no consent and nobody on them knows you. A good list is built from the touchpoints you already have:
- Booking engine: an unticked newsletter box and an opt-out notice for direct bookers.
- Check-in, paper or digital: a clear line and box for hotel news and offers.
- Hotel Wi-Fi: if you use a login page, keep the newsletter optional and separate from getting online.
- A QR card in the room or at check-out with a perk for their next direct booking.
- Website: a real reason to sign up, such as early access to next season's dates or first look at winter packages.
- A record of every sign-up: date, source, language and the wording they agreed to. Your email platform should store it.
- The guest's language saved from day one, so you always write in theirs.
The emails your hotel actually needs
You don't need a weekly newsletter. A boutique hotel does better with a handful of well-timed sends, each in the guest's own language:
| When | Purpose | |
|---|---|---|
| Confirmation | On booking | Dates, terms, how to get there. Informational, not promotional. |
| Pre-arrival | A few days before | Arrival time, transfer, dinner, preferences. Helpful, not pushy. |
| Post-stay | A day or two after | Thank you, plus a link to leave a Google review. |
| Priority dates | Before next season goes on sale | Early access for past guests, with their book-direct perk. |
| Shoulder and low season | Autumn and winter | Specific packages: breaks, retreats, long stays. |
| Anniversary | A year after their stay | A personal note and an invitation back. |
Segment at least by language, guest type (couple, family, group) and when they stayed. An August family doesn't want the same offer as an October couple. For winter ideas, see our guide on how to fill an Ibiza hotel in low season.
Remarketing on Google and Meta without stalking anyone
Remarketing shows ads to people who have already visited your site. Done well, it reminds the undecided that you exist; done badly, it follows someone for weeks after they've booked. The basics:
- High-intent audiences. People who viewed rooms or opened the booking engine, not every blog reader.
- Exclude anyone who has booked and current in-house guests.
- Short windows and capped frequency. Seeing the same ad for months irritates more than it persuades.
- One message per language and moment. English ads for English-language visitors; book-direct perks in season and packages in winter.
- Consent only. If a visitor rejected advertising cookies, they don't go into your audiences. Your audience will be smaller, and clean.
Remarketing can't fix a site that doesn't convert: if the visitor left because the booking engine was slow or confusing, the ad sends them straight back to the same problem. Check the fundamentals in our guide to direct bookings vs OTAs for Ibiza hotels.
Email and remarketing work best inside a plan that also covers your website, Google and social media. To see the full picture, start with our hotel marketing in Ibiza page.
Frequently asked questions
Can I email past guests offers without asking first?
If they booked directly with you, LSSI article 21.2 allows emails about similar services, provided you offered an opt-out when you collected the address and in every message. If they booked through an OTA, or you never offered that opt-out, ask for express consent.
Do I need consent for remarketing on Google or Meta?
Yes. Remarketing tags and pixels use advertising cookies, which need consent. The Spanish data protection authority requires a reject button as prominent as the accept button, and pixels shouldn't load until the visitor accepts.
Do UK rules apply if my guests are British?
Your hotel is established in Spain, so EU GDPR and the Spanish LSSI are your starting point, whoever the guest is. If you also run a business based in the UK, check with a specialist whether UK rules apply to that side too. In practice, consent and clear opt-outs keep you safe in both.
How often should a boutique hotel send emails?
Rarely, and always with a reason: confirmation, pre-arrival, a thank-you with a review link, priority dates before the season, autumn or winter packages and an anniversary note. Six useful emails a year beat a weekly newsletter nobody opens.
