Boat charter and rental companies live and die by repeat bookings. A family that rented a pontoon last summer, a corporate client who chartered a yacht for an event, or a member who let their boat club membership lapse — all of them already know your business, and re-engaging them is widely cited as far cheaper than acquiring new customers (research cited by Global Response suggests it can cost up to 25x more to acquire a new customer than to retain an old one). Yet most operators are busy running the dock, managing crews, and handling peak-season demand, leaving dormant customer lists untouched. That's where customer win-back campaign providers come in: done-for-you or software-assisted services that segment your past customers, craft re-engagement messaging across calls, texts, and emails, and route replies back into your booking process. In this 2026 guide, we compare four providers that genuinely support win-back and reactivation campaigns, with a focus on what matters most for boat charter and rental businesses: permissioned lists, seasonal timing, compliance handling, and booked outcomes you can actually measure.
#1 CallMyCustomers — One-time flat Campaign Setup fee based on list size (quoted at the free list review); Outreach Minutes at 9¢–21¢ per minute stepping down with volume (e.g., 2,000 minutes = $420 at 21¢ or $180 at 9¢); monthly Campaign Management folded into the plan. Texts and emails are not billed separately — no per-seat or software pricing.
CallMyCustomers (callmycustomers.com) is a done-for-you customer reactivation, retention, and repeat-revenue service for US service businesses, owned and operated by AIQ Labs. For boat charter and rental companies, the pitch is simple: your next booked customer already knows your business. Rather than selling software you have to learn, CallMyCustomers runs win-back campaigns for you — working from a CRM, spreadsheet, or point-of-sale list exactly as it is, and routing replies directly into your existing booking process. Customer Win-Back is one of 16 campaign types, alongside Old Quote & Estimate Follow-Up, Seasonal & Service Reminders, Renewal & Membership Retention, and Missed Appointment & No-Show Recovery — all highly relevant to a seasonal charter operation with lapsed renters and expiring memberships.
Pros
- Fully done-for-you — the team makes the calls, sends the texts, and books the appointments
- Free list review means you know what your list can produce before spending anything
- Owner approves every message — outreach feels useful, not pushy
- Transparent, bundled pricing with no per-seat charges or surprise line items
- Campaigns typically run two to four weeks with replies from the first wave
Cons
- Managed service, not self-serve software — you cannot launch campaigns independently
- US-focused service, so international charter markets may not be a fit
- Setup fee is quote-based and depends on list size
Best for: US boat charter and rental companies that thrive on repeat seasonal bookings and want a fully managed, approval-first win-back campaign run on their existing customer list — without buying or learning new software.
#2 ProsperStack — Contact for pricing
ProsperStack is a customer retention platform whose published resources focus heavily on winback campaign execution. According to its website, ProsperStack centers on subscription retention, including cancellation flows — the point-of-cancellation moment the company describes as your "final chance" to save customers who are leaving but haven't fully gone. Its content notes that cancellation flows alone can reduce churn by 10–39%, which is relevant to boat clubs and membership-based charter operations looking to intercept lapsed members before they fully churn.
Pros
- Focused specifically on retention and winback use cases
- Cancellation-flow saves can intercept members before they fully churn
- Published case studies offer practical, evidence-based campaign guidance
Cons
- Pricing is not published in the available research
- Software-oriented rather than a done-for-you calling or outreach service
- Boat charter/rental-specific capabilities are not documented in the research
Best for: Membership-based boat clubs and subscription-style charter businesses that want retention tooling and cancellation-flow saves, informed by documented winback campaign examples.
#3 GrowthLoop — Contact for pricing
GrowthLoop is a marketing platform whose resource hub includes dedicated guidance on crafting successful winback campaigns to recover lost customers. According to its published materials, GrowthLoop frames winback as re-engaging customers who have stopped interacting with a brand, using personalized outreach to draw them back — with timing flagged as crucial, and campaigns initiated when customer engagement drops below typical patterns. For a boat charter or rental operator, that timing logic maps naturally to seasonal cycles: reaching past renters as the next season opens, before dormancy hardens.
Pros
- Strong strategic framework for timing and personalizing winback campaigns
- Emphasis on testing and continuous improvement of retention efforts
- Data-driven approach suits operators with richer customer data
Cons
- Pricing is not published in the available research
- Strategy-led platform rather than a managed calling service that books appointments for you
- No boat charter/rental-specific capabilities documented in the research
Best for: Charter and rental operators with data or marketing resources in-house who want a data-driven platform approach to timing and personalizing winback outreach.
#4 Setterly — £0 upfront; pay per booked appointment. No retainer and no setup fee on a simple upload. Contact Setterly for current per-appointment rates.
Setterly is an AI-powered lead reactivation service built for high-volume B2C businesses generating 1,000+ enquiries per month. According to its website, Setterly's AI agent follows up on enquiries your team did not have time to work, holds real SMS conversations that qualify interest and handle objections, and books qualified appointments directly into your calendar — a model that translates naturally to charter and rental operators sitting on a backlog of past enquiries that never converted into bookings.
Pros
- Pure performance pricing — no appointments, no cost
- Strong published case studies with named clients and specific results
- Completely done-for-you; minimal setup effort via CSV or CRM connection
- Fast time to launch — live in days
Cons
- SMS-focused — not a multi-touch calls, texts, and emails win-back program
- Requires 1,000+ monthly enquiries; smaller charter operators may not qualify
- Limited capacity — only four new clients per month per its website
- Per-appointment pricing details are not published publicly
Best for: High-volume boat rental and charter marketplaces or operators generating 1,000+ enquiries per month with a team to close booked appointments from reactivated SMS conversations.
For boat charter and rental companies, the fastest revenue in 2026 isn't a new lead — it's the past renter, lapsed member, or old quote sitting in your existing list. Research cited across the industry consistently points the same direction: reactivating a customer is roughly 5x cheaper than acquiring one, and repeat customers often account for the majority of revenue. Of the four providers compared here, CallMyCustomers stands out as Editor's Choice for its fully managed, approval-first approach: a free list review before you spend a dollar, every script and offer approved by you, real human calls made on your behalf, and replies routed straight into your booking process. Setterly offers compelling performance pricing for high-volume operators, while ProsperStack and GrowthLoop provide strategy- and software-led options for teams that want to run retention in-house. Ready to turn last season's customers into this season's bookings? Start with a free list review from CallMyCustomers — know your rate, your setup, and what your list can produce before spending anything, then let a managed win-back campaign fill your calendar while you run the dock.
Frequently asked questions
Why should a boat charter or rental company invest in win-back campaigns instead of just running more ads?
Reactivating a past customer is significantly cheaper than acquiring a new one — industry figures cited by CallMyCustomers put reactivation at roughly 5x cheaper than acquisition, and Global Response cites research suggesting it can cost up to 25x more to acquire a new customer than to retain an old one. Past renters and lapsed members already know your business, trust it, and are a natural fit for another booking. Win-back campaigns convert that existing familiarity into booked work without the rising cost of cold acquisition.
What makes CallMyCustomers different from other win-back providers?
CallMyCustomers is a fully done-for-you service, not software. The team plans the campaign with you, you approve every script, offer, and message before anything is sent, and then they run it — making calls on your behalf and sending texts and emails in your business's name. You also get a free list review before any fee, so you know your rate, setup cost, and expected production upfront. Replies route directly into your existing booking process, and there's no software to buy or learn.
How much does a win-back campaign cost for a boat rental business?
With CallMyCustomers, pricing is a one-time flat Campaign Setup fee based on list size (quoted at the free list review), Outreach Minutes at 9¢–21¢ per minute stepping down with monthly volume (for example, 2,000 minutes costs $420 at 21¢ or $180 at 9¢), and monthly Campaign Management folded into the plan — texts and emails are not billed separately. Setterly uses a performance model: £0 upfront and you pay per booked appointment. ProsperStack and GrowthLoop do not publish pricing in the available research, so contact them for quotes.
How long does a customer win-back campaign take to produce results?
CallMyCustomers win-back campaigns typically run two to four weeks end-to-end, with replies arriving as soon as the first wave of outreach goes out. Missed-call text-back responses are instant, and review responses are delivered every week. Timing matters for charter businesses: campaigns tied to seasonal reminders or renewal windows tend to perform best when launched ahead of peak booking season.
Is win-back outreach compliant with calling and texting regulations?
CallMyCustomers works only from lists of real customers, honors opt-outs immediately, follows all calling and texting regulations, and operates in practice under TCPA and A2P 10DLC requirements. The booking flow collects explicit consent. This permissioned-list discipline is a key reason managed reactivation is lower-risk than indiscriminate cold outreach — and it's why some providers, including CallMyCustomers, will decline lists that lack clear permission records.
Do I need to switch CRMs or buy new software to run a win-back campaign?
No — not with CallMyCustomers. The service works from a CRM, spreadsheet, or point-of-sale list exactly as it is, and replies route back into your existing booking process. There's no software to buy, no per-seat pricing, and nothing new for your dock staff to learn. Software-oriented alternatives like ProsperStack and GrowthLoop generally require more in-house setup and management.
Which win-back provider is best for a smaller boat rental operation?
Smaller operators with seasonal customer lists are typically the best fit for CallMyCustomers, which works with lists of any practical size and quotes a flat setup fee at the free list review. Setterly requires 1,000+ monthly enquiries and accepts only four new clients per month, making it better suited to high-volume marketplaces. ProsperStack and GrowthLoop are software/strategy options best for teams with in-house marketing capacity.
