One underused marketing channel, a 4-step process, and a voice memo recorded on your phone. Here's the full playbook.
Most RV park owners rely on word of mouth, Google, or maybe a Facebook post to fill vacant spaces. But there's a channel almost nobody in this industry is using that delivers messages directly to your warmest leads — past renters and people who already showed interest but didn't convert — for pennies per contact. It's called a ringless voicemail drop. Here's the exact process to run your first campaign today.
What is a ringless voicemail?
A ringless voicemail (RVM) is a recorded audio message delivered directly to someone's voicemail inbox — without their phone ever ringing. On the recipient's end, it appears as a missed call and a new voicemail from whatever number you specify. They listen when it's convenient, and if they're interested, they call back.
It's non-intrusive, personal-feeling, and because almost no RV park operators are using it, your message stands out.
The 4-step campaign process
1
Build your contact list
Pull two groups of phone numbers from your records:
- Past renters — guests who stayed with you previously but haven't returned. They already know your park. They're your warmest audience.
- Cold leads that didn't convert — people who inquired, filled out a form, or called but never booked. They showed intent. Maybe the timing was off, or you were slow to respond. Now you have another shot.
Most parks can pull 100–300 numbers from their CRM, booking software, or even a spreadsheet. Export them to a single CSV.
2
Create your list in Slybroadcast
Go to Slybroadcast.com and create an account. Upload your CSV and name the list something specific like "April 2026 Campaign" so you can track it and reuse it for future drops.
Slybroadcast is built exactly for this — it routes audio directly into voicemail systems without triggering a ring. Pricing is typically a few cents per contact, so a list of 200 numbers costs under $10.
3
Record your voicemail
Open your phone's voice memo app and record a message in your own voice. Keep it under 30 seconds. Personal, direct, and with a clear offer and deadline. Use this template:
Script Template
"Hi, this is [YOUR NAME] and I'm the owner of [PARK NAME] here in [CITY/AREA]. I wanted to personally call and offer you [SPECIAL OFFER] if you book a space with us by [DATE]. Call me back at this number or stop by [PARK ADDRESS] for more information!"
Fill in your real name, park name, a genuine offer (a free night, discounted weekly rate, priority site selection), and a specific deadline to create urgency.
4
Upload and send
Upload your audio file to Slybroadcast, select your contact list, set the number you want recipients to call back (your direct line or park office), and hit send.
The messages are delivered directly to voicemail inboxes. No phone rings. No spam filters. No algorithm deciding who sees it.
What to expect
Here's how the numbers typically shake out for a park with a modest list:
~5%
Average callback rate
100–300
Typical contact list size per park
Under $10
Cost per campaign
At 5% callback rate on 200 contacts, that's 10 people calling you back — people who already know your park or already showed interest. Converting even half of those callbacks means 5 new bookings from a single $10 campaign.
Why this works for RV parks specifically
Your past renters are not gone forever. Many of them relocated to a different park — often because the next park responded faster, ran a promotion, or simply reached out. They're still RVers. They still need a place to park.
Same for cold leads: someone who inquired in January and went somewhere else may have had a bad experience, be ready to try again, or simply need to hear from you one more time.
A personal voicemail from the owner — not a text blast, not an email, not a social media ad — feels different. It signals that you actually care about having them back.
Tips for a stronger campaign
- Make the offer real. A vague "special offer" won't get callbacks. Name it: "one free night with a weekly booking," "$50 off your first month," or "guaranteed pull-through site."
- Use a hard deadline. "By May 1st" converts better than "soon" or "this spring." Urgency is the difference between someone saving the voicemail and deleting it.
- Record it yourself. A professional-sounding AI voice or a staff member reading a script will underperform. Park owners calling their own guests is the whole point. Your voice, your name, your park.
- Pick up your callbacks. If you're running this campaign, make sure someone is answering the phone for the next 48–72 hours. The conversion happens in that window.
- Segment your lists over time. Past renters from last season vs. leads that never converted deserve slightly different messages. As you run more campaigns, refine your segments.
