Email subject lines that outdoor customers actually open
Your email list is one of the most direct lines you have to past and future customers. But if nobody opens your emails, you might as well not send them. For outdoor businesses, the subject line is where bookings are won or lost - and most operators are writing theirs wrong.
The average click-to-open rate in travel and tourism sits around 6% in 2025. That means even when people open your email, most won’t click through. The subject line is what gets you to the starting line. Writing better ones is the fastest, cheapest thing you can do to get more revenue from a list you’ve already built.
This guide covers exactly that.
Why most outdoor email subject lines fail
The generic ones look like this: “June Newsletter,” “Exciting Updates from XYZ Adventures,” or “Don’t miss out on our summer trips.” These fail for three reasons.
They’re vague. “Exciting updates” tells someone nothing about what’s inside - if a person can’t decide in two seconds whether to open an email, they won’t. They also sound like every other business’s marketing email. A fly fishing guide in Montana and a cruise company in Miami sound identical when both write “Your next adventure awaits.” Worse, phrases like “don’t miss out,” “last chance,” and “act now” look like spam to filters. Enough of those in your sending history and your emails start landing in junk before anyone decides whether to open them.
The subject line is the only thing most readers see before they decide. According to research across email platforms, 47% of recipients open emails based on the subject line alone. Everything else is secondary.
The elements that make a subject line work
Good subject lines for outdoor businesses share a few traits. They’re specific, short enough to read on a phone, and they hint at something worth opening.
Specificity beats enthusiasm every time. “June whitewater trips filling up” outperforms “Summer season is here.” The first tells someone something concrete - the second says nothing. A Colorado rafting company testing both versions reliably finds the specific one opens more. Specific subject lines also set accurate expectations, which reduces the mismatch between subject and content that generates unsubscribes.
Short is a technical requirement, not just a style choice. Most smartphones show 28 to 32 characters of a subject line. If your subject is “Get ready for the best outdoor adventure of your life this summer,” most people see “Get ready for the best outd-” and nothing more. Keep it under 50 characters. Under 40 is even better for mobile.
Questions get opened. Subject lines framed as questions consistently outperform statements by 10–21% in open rate studies. “Ready for your first whitewater trip?” or “Still looking for fall fishing dates?” create a small itch the reader wants to scratch. Use sparingly - if every email you send is a question, it stops working.
Personalization adds a few points without adding complexity. Adding the recipient’s first name in a subject line lifts open rates by about 26% on average. Mailchimp, ActiveCampaign, Klaviyo, and FareHarbor’s email tools all support it - it’s a two-minute setup. “Sarah, your August reservation is confirmed” performs better than the same email without the name.
Subject lines by email type
Different emails in your sequence call for different subject line approaches. What works for a promotional email sending to a cold list doesn’t work for a post-trip follow-up to someone who just spent $400 with you.
Promotional emails (announcing trips, seasonal openings, special pricing): Lead with the specific thing you’re selling. “August float trips open for booking,” “Fall foliage hikes - 3 dates left,” or “Winter snowshoeing tours are back.” Avoid mentioning price in the subject unless the price itself is the news.
Pre-trip emails (sent after booking, building excitement): These are high-open emails because the customer is primed. Make the subject feel useful, not marketing-y. “What to pack for your Colorado rafting trip,” “Your Smoky Mountain zip line checklist,” or “3 things to know before your guided fly fishing day.” These get opened because the person wants the information.
Post-trip emails (review requests, rebooking, referral): Be direct. “How was your trip, [Name]?” opens better than anything fancier. For rebooking: “Spots open for next summer - you’re first to know.” For referrals: “Know someone who’d love what you just did?”
Off-season emails (staying in touch during slow months): These require the most craft because you’re asking someone to open an email when they’re not actively planning. “What we’re doing this winter” works better than “Our off-season newsletter.” Content previews outperform vague teasers.

What to avoid
A few patterns hurt outdoor businesses specifically.
Scarcity language that sounds fake. “Only 2 spots left!” works when it’s true. When customers know you run 15 trips a week, they don’t believe it. Authentic scarcity (“Our October trips book up by August - here’s why”) is more effective and doesn’t erode trust.
Caps, exclamation marks, and emoji in the subject. These aren’t just aesthetically rough - they trigger spam filters. A subject like “🔥 AMAZING DEALS on summer adventures!! 🏕️” has a real chance of landing in junk. Even if it doesn’t, it positions your business as amateur.
Generic adventure language. “Your next adventure awaits” is used by literally thousands of tour operators, travel brands, and gear companies. We’ve seen outfitters send this subject line to guests who just rafted the Arkansas River with them - people who paid $150 and had a great time. It registers as noise. Write subject lines that could only come from your specific business: “New put-in for our Salmon River trips,” “We added a guided snowshoe route on Mt. Rainier.”
Misleading subjects. If your subject says “free trip planning guide” and you send a promotional email, you’ll get clicks but also unsubscribes. Match subject to content exactly. The short-term open rate lift isn’t worth the list damage.
Testing your subject lines
You don’t need a massive list to start learning what works. Most email platforms let you A/B test subject lines - send version A to 20% of your list, version B to another 20%, wait a few hours, then send the winner to the remaining 60%.
Test one thing at a time. Don’t compare a short subject to a long personalized one with different framing - you won’t know which variable drove the difference. Start with the most impactful test: question vs. statement for the same email. Then test with vs. without personalization. Then test specific vs. general.
Keep a simple log. What you learn about your specific list - fishing guides vs. rafting companies, locals vs. destination travelers - is more useful than any industry benchmark. Your customers opened your emails for a reason. Figure out what that reason is and write to it.
If you’re building out a full email system, subject lines are the entry point but not the whole story. See how subject lines fit into a broader sequence in the guide to 7 automated email sequences every outdoor business needs. And for segmenting your list so the right subject line reaches the right reader, the email segmentation guide for outdoor businesses is worth reading alongside this one.
The sender name problem nobody talks about
Most operators focus entirely on the subject line and ignore the sender name - which is the other thing recipients see before they decide to open. “info@coloradoriverguides.com” gets ignored. “Jake from Colorado River Guides” gets opened.
This costs nothing to change. In your email platform, set the “from name” to a real person at your business. It doesn’t have to be the owner - it can be your guide manager, your booking coordinator, anyone who can plausibly be the person writing the email. Customers who’ve been on a trip with you already have a relationship with a human. Remind them of that.
The subject line and sender name work together. “Jake from Colorado River Guides” and “Your August trip is almost here” beats “info@coloradoriverguides.com” and the same subject by a margin every time.
Write your next five emails before you worry about your automation setup or your ESP’s deliverability score. The subject line is the thing your customers see first, judge fastest, and use to decide whether you’re worth their time. Get that right and everything else gets easier.
Your list already trusts you enough to stay subscribed. Give them a subject line worth opening.
