My Newsletter Open Rates Are Tanking — What to Actually Do

When your email open rates drop, you lose your most profitable booking channel. This guide covers how to fix technical issues and rewrite your strategy for 2025.

If you’ve noticed your email open rates sliding from a healthy 40% down to a depressing 15%, you aren't just losing "engagement"—you are losing your cheapest channel for repeat bookings and referrals. In an industry where OTA commissions eat 20-30% of your margin, a dying newsletter is a leak in your most profitable bucket.

The reality of the tour industry is that people don't buy tours every week, but they do plan their next three years of travel constantly. If your emails are landing in the "Promotions" tab or, worse, being ignored because they look like a generic flyer, you are effectively invisible. I’ve managed an aggregated €10M+ in revenue across my portfolio, and a significant portion of that comes from maintaining a clean, high-performance email list that people actually want to read.

Here is how you diagnose the rot and fix your newsletter open rates without using "hype" or clickbait.

1. The Audit: Is it Deliverability or Content?

Before you change a single word of your copy, you need to know if your emails are even reaching the inbox. If your open rate is below 20%, you likely have a technical deliverability problem. If it’s between 25% and 35% but dropping, you have a relevance problem.

First, check your sender reputation. If you’ve been blasting your entire list of 10,000 past guests with the same "10% off June" coupon for three years, Gmail and Outlook have flagged you as a low-value sender.

How to verify your technical health: 1. Check your SPF/DKIM records: Ensure your domain is authenticated so you don't look like a spoofing account. 2. Monitor "Spam Complaint" rates: Anything over 0.1% (1 in 1,000) is a red flag. 3. Clean the "Zombies": If someone hasn't opened an email in 6 months, they are actively hurting your ability to reach the people who do want to hear from you.

2. Aggressive List Hygiene (The "Purge" Framework)

It feels counterintuitive to delete subscribers you paid to acquire, but a smaller, active list is objectively more valuable than a large, dead one. ISP algorithms (Google, Yahoo) look at your "Engagement Rate" to decide whether to put you in the Inbox or the Spam folder. If 70% of your list ignores you, the ISP assumes the email is junk.

My 3-Step Purge Framework:

Within two weeks of doing this, those who remain will see your emails more often because your "Sender Score" will skyrocket.

3. Move from "Broadcast" to "Behavioral" Segments

Most tour operators treat their newsletter like a megaphone. They send the same update about a new van or a seasonal festival to everyone. But a corporate traveler who booked a Lisbon incentive trip has zero interest in your "Family Half-Day Surf Lesson" discount.

You must segment your list based on the intent they showed when they booked or signed up.

1. Lead Origin: Did they download a "Local's Guide to Madrid" or did they book a "Private Tapas Tour"? 2. Travel Persona: Family, Solo/Backpacker, Luxury/Couple, or Corporate. 3. Spending Habits: High-yield private tour clients vs. budget-conscious group tour travelers.

By sending a specific email to a segment of 400 people, you will often get more bookings than sending a generic email to 4,000. Relevance is the only way to sustain high open rates over the long term.

4. Subject Lines: The "Anti-Newsletter" Approach

If your subject line looks like a newsletter title (e.g., "Our June Newsletter" or "Spring Updates from [Company Name]"), people will skip it. Their brain categorizes it as "Ad" immediately.

To get opens in 2024 and 2025, you need to write like a person, not a department. Use "Sentence Case" (only the first letter capitalized) rather than "Title Case." It feels more like an email from a friend or a specific guide.

What to stop doing immediately:

What to do instead:

5. Frequency vs. Consistency

A common mistake is thinking you need to email every week. If you have nothing of value to say, emailing every week just trains your audience to ignore you.

I prefer a "Pulse" strategy. During the lead-up to your peak booking season (e.g., January-March for European summer tours), increase frequency with high-value planning content. During the off-season, drop the frequency but increase the depth. Use that time to tell "Behind the Scenes" stories or profile your guides.

When you do send an email, ensure it follows the 80/20 rule: 80% education/entertainment (the "Value") and 20% sales (the "Ask").

Summary Checklist for Recovery

If you apply these changes today, you should see a measurable lift in open rates within 3 to 4 send cycles.

1. Verify your technical domain settings (SPF/DKIM/DMARC). 2. Delete any subscriber who hasn't opened in 6 months. 3. Switch to plain-text style emails (less HTML, more "operator-to-guest" vibes). 4. A/B test your subject lines with a focus on sentence case and curiosity. 5. Stop sending "Newsletters" and start sending "Recommendations."

What I’d Do Next

Fixing your email list is part of a larger "Direct Booking" strategy. Most operators are too reliant on the "OTA drug"—waiting for Viator or GetYourGuide to send them crumbs while paying 25% for the privilege.

If you are currently doing €1M+ or €2M+ in annual revenue and want to transition into a high-margin, direct-booking machine, we should talk. I don't do "coaching calls" with fluff. I look at your numbers, your tech stack, and your distribution, and I tell you where the leaks are.
