Cruise line newsletters: what passengers actually want to read
Past passengers open your newsletter at 40%, then never click. The subject line is rarely the problem — what sits inside the email usually is.
Pull up your last send. On a list of past passengers, a 35–45% open rate is unremarkable — people who spent eight days aboard your ship are happy to open your email. Then click-through drops to 2%. That gap isn’t a subject-line problem or a send-time problem. The content simply doesn’t pay off the open.
They open for the sea, not for your cabin inventory
Your passenger opens because he’s thinking about his trip again. What he finds is “8-day Baltic cruise from £1,090 — book before the 30th.” The emotional thread snaps instantly. A brochure wearing a newsletter costume fools nobody, and hasn’t for a decade.
What actually gets read is what he can’t find anywhere else: why the Riga call moved this season, what the staff captain watches when the swell builds, how a gala dinner for 600 covers gets prepped, the notebook of a head chef who brings his own Breton suppliers aboard. You have a ship, a crew and a string of ports. That’s an entire editorial desk — it costs nothing beyond the time to let those people talk.
A working ratio: three parts story, one part commerce
Rotate your issues. One on the craft, one on a destination seen up close, one on your own passengers — and put the offer at the bottom of every send, never in the headline. A newsletter isn’t a direct-sales channel. It keeps a relationship warm. The booking happens later, when the passenger decides on his own that he’s going again.
Here’s the number that reframes it: repeat cruisers typically wait 18 to 30 months between sailings. Over that stretch, a monthly newsletter is roughly twenty touches. Twenty promotions produce one unsubscribe. Eighteen genuinely good ones make the other two sell themselves.
The structural gap: it only reaches people who already know you
That’s the ceiling. A newsletter maintains a relationship; it never creates one. Your strongest prospects aren’t on your list at all — they’re the people close to your passengers. Same age bracket, same disposable income, same appetite for travel. The statistical twin of your customer, and no ad platform will find him as accurately as your customer already has.
This is where a physical piece wins. A real postcard in the line’s colours, written aboard and sent to a sister or a neighbour, printed and posted in France: it lands in a letterbox with familiar handwriting on the back. That isn’t advertising, it’s a recommendation. And unlike your newsletter, deleted in three seconds, it sits on a fridge door for something like five years. Related reading: the onboard postcard.
What to measure instead
Stop steering by open rate. Track unsubscribes by content type, and the lag between your last send and a booking. You’ll know within two quarters which issues are doing the work. And if you want to weigh a newsletter against a physical channel, run your own figures through the ROI calculator — the comparison catches out plenty of marketing teams who thought they had this one figured out.
