Email deliverability for outdoor businesses: why your emails land in spam

If your emails are landing in spam, you’re not just missing opens. You’re losing bookings that were already halfway there. A guest who signed up on your list after a trip, or clicked through your off-season promotion, had to actively give you their address. If your message never reaches their inbox, that relationship is gone before it starts.

Email deliverability is the technical side of whether your emails actually get delivered to the inbox versus the spam folder (or nowhere at all). Most outdoor operators have never thought about it. Then one day their open rates drop from 35% to 8% and they don’t know why.

Here’s what’s going wrong, and what to fix first.

Why outdoor businesses have a deliverability problem

The patterns that define outdoor businesses are also the patterns that break email deliverability.

You run a seasonal operation. You might go three or four months without sending a single email, then blast your entire list in March to announce the new season. From an email server’s perspective, a domain that’s been quiet for months suddenly sending hundreds of emails looks suspicious. Your sender reputation takes a hit before your subscribers even see the subject line.

The other issue is list quality. Outdoor businesses collect email addresses in ways that create problems: paper sign-up sheets at events where someone writes an illegible address, waivers where guests enter fake emails just to get through the process, business card fishbowls at trade shows, or lists purchased from equipment manufacturers. Every invalid address that bounces back damages your standing with email providers.

And then there’s the tool problem. Many small outfitters send from their website hosting provider’s email (something like reservations@raftingcompany.com configured through cPanel) rather than a proper email service provider. Those DIY setups almost never have proper authentication configured, and they share sending infrastructure with thousands of other low-reputation senders.

What authentication actually means and why it matters now

Three technical records (SPF, DKIM, and DMARC) determine whether receiving email servers trust that you are who you say you are.

SPF (Sender Policy Framework) is a DNS record that tells the internet which mail servers are authorized to send email from your domain. If you send through Mailchimp but your SPF record doesn’t list Mailchimp as an authorized sender, Gmail may treat your message as potentially spoofed.

DKIM (DomainKeys Identified Mail) adds a digital signature to your emails. When a message arrives at Gmail, Google checks that signature against your domain’s DNS records. If it matches, the email wasn’t tampered with in transit and genuinely came from you.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on both. It tells receiving servers what to do if SPF or DKIM fails: deliver it, quarantine it in spam, or reject it outright. As of 2024, Gmail and Yahoo both require DMARC for anyone sending bulk email.

Most small outdoor operators have never set any of these up. That’s not a knock. Nobody teaches you this when you’re starting a rafting company or a fishing guide service. But as of 2024, sending bulk email without DMARC in place is a good way to have Gmail quietly route your entire campaign to spam with no warning.

If you’re not sure whether your domain has SPF and DKIM configured, go to MXToolbox.com (mxtoolbox.com) and run a free check. Takes about 30 seconds.

Your email service provider (Mailchimp, ActiveCampaign, Kit, whatever you use) will have help docs on setting these up. It involves adding a few DNS records through your domain registrar (GoDaddy, Namecheap, Squarespace, wherever you registered your domain). Not glamorous. But it’s the single biggest deliverability fix available to most small operators.

How sender reputation works and how you destroy it

Every domain and IP address that sends email has a reputation score, maintained by email providers like Google and Microsoft. High reputation = inbox. Low reputation = spam folder or outright rejection.

Your reputation goes up when people open your emails, click links, and reply. It goes down when people mark your email as spam, ignore it entirely, or when your messages bounce.

Google Postmaster Tools is a free service that shows you your domain’s reputation and spam rate as Gmail sees it. If your spam complaint rate exceeds 0.4%, you have a problem. Most outdoor operators who are in the spam folder are well above this and don’t know it, because they’ve never checked.

Hard bounces (emails sent to addresses that don’t exist) are particularly damaging. Send to enough of them and you start looking like a spammer. A healthy list should have a hard bounce rate under 2%. If you’ve never cleaned your list or you’ve imported old addresses from a waiver form, you’re likely above that.

We’ve seen outdoor businesses with lists of 3,000 subscribers where 800+ addresses were invalid or dormant. Their open rate looked “okay” because the denominator was inflated with dead weight. When they cleaned the list down to 1,800 active contacts, their open rate jumped and their deliverability recovered.

What happens when you send after months of silence

This is the most common deliverability mistake seasonal businesses make.

You close in November. Your list sits untouched through the winter. In March, you send a “we’re back” campaign to everyone who’s signed up over the past two years. Several things go wrong simultaneously.

First, some of those addresses have gone inactive or changed since people signed up. Those bounce. Second, email providers note that your domain was quiet for months and is now sending a large volume, which is a pattern associated with compromised accounts and spam operations. Third, some subscribers forgot they signed up and hit the spam button.

The fix is gradual re-engagement, not a cold blast. Before peak season, start sending small batches. Send to your most engaged subscribers first, meaning people who opened something in the last six months. Let that go for a week, check the results, then expand to less-engaged segments. This “warming up” approach signals to email providers that you’re a legitimate sender with real engagement.

The spam trigger words problem (and why it’s overblown)

Yes, subject lines and email bodies with words like “FREE,” “GUARANTEED,” “ACT NOW,” and “CLICK HERE” can trigger spam filters. You should avoid them.

But spam filter vocabulary is a distant second concern compared to authentication and list hygiene. Most outdoor operators who are getting routed to spam aren’t there because they wrote “FREE GEAR” in all caps - they’re there because they’ve never configured SPF, haven’t cleaned their list in two years, or went dark for five months and came back with a 2,000-person send. Fix the infrastructure first.

Still, a few specific patterns trip filters in outdoor email marketing:

All-caps subject lines get flagged. Excessive use of the word “free” (as in “free cancellation,” “free gear check”) can trip filters. Just describe the thing instead. Image-only emails with no text content are problematic because spam filters can’t evaluate them for context.

Worth addressing, but not the root of the problem for most outdoor operators.

Using list segmentation to protect deliverability

One thing that helps deliverability and improves results at the same time: only send emails to people who are likely to open them.

When you send to your entire list every time, the people who never open your emails drag down your engagement rate. Email providers track this. A list with a consistent 40% open rate sends a strong reputation signal. A list with an 8% open rate sends a weak one.

Segment out subscribers who haven’t opened anything in the last 12 months and stop including them in regular campaigns. Before you remove them entirely, run a re-engagement sequence: two or three emails specifically asking if they want to stay on your list, with a clear yes/no prompt. Anyone who doesn’t respond after that sequence gets removed. Your list shrinks, your open rate improves, and your sender reputation climbs.

Which email platform you use actually matters

Not all email service providers have the same deliverability infrastructure. In real-world testing across major platforms, inbox placement rates range from around 64% on the low end to 92% on the high end. That gap is real and it affects your bookings.

Kit (formerly ConvertKit) consistently tests at the top of independent deliverability rankings, around 92% inbox placement. Mailchimp sits in the high 80s, which is solid for most use cases. Some cheaper platforms have significantly worse infrastructure and it shows.

If you’re currently sending from your web host’s email (Bluehost, GoDaddy hosting, SiteGround, similar) rather than from a dedicated email marketing platform, switching to an ESP is the single most impactful move you can make for deliverability. You’ll get proper authentication, bounce handling, unsubscribe management, and reputation monitoring all built in. The Mailchimp vs. ActiveCampaign vs. Klaviyo comparison covers the platform choices in detail.

A basic deliverability audit you can do this week

Start with the free tools.

Check your DNS records at MXToolbox.com. Enter your domain, run the MX Lookup and SPF lookup. If SPF isn’t configured, your email platform’s help docs will walk you through adding the record to your DNS.

Set up Google Postmaster Tools (postmaster.google.com) if you haven’t. Verify your domain, and within a few weeks of sending you’ll have data on how Gmail rates your domain reputation and whether any of your messages are being flagged as spam.

Check your bounce rate in your last three campaigns. Hard bounces above 2% mean you need to clean your list before your next send.

Look at open rates over the past year. If they’ve dropped steadily - say, from 28% to 14% - without any obvious content change, it’s likely a deliverability issue, not just a relevance issue.

The email marketing definitive guide for outdoor recreation covers the full picture of building a list that actually converts to bookings. But none of that works if your emails aren’t reaching inboxes.

Fix authentication first, then clean your list, then worry about your subject lines. In that order.
