Top 5 Win-Back & Reactivation Calls Providers for Managed IT Services Provider (MSP)s

Every MSP has a list of former clients and dead deals that quietly haunts the CRM. A contract that wasn't renewed, a proposal that stalled when the prospect renewed with their current provider, a one-off project client you never called again. That list is worth real money. A single reactivated managed services contract at $4,000 a month is worth nearly $50,000 a year, and the prospect already knows who you are, which makes reactivation far cheaper than chasing new leads. The problem is that working a dormant list takes time your team doesn't have, and generic "just checking in" emails get ignored. In 2026, a growing set of providers will run win-back and reactivation calling campaigns for you, from managed AI calling services to human-agent call centers to full outsourced reactivation programs. This guide compares the top five options for MSPs, looking at how each handles outreach, compliance, pricing, and reporting, so you can pick the partner that fits your book of business and your comfort level with outsourcing client conversations.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. No per-seat charges, no platform bill, no minimums you didn't choose. The first campaign review is free.

My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. It's owned and operated by AIQ Labs, based in Halifax, Nova Scotia, with an operating base in Austin, Texas. The pitch is simple: run more useful calls without building a bigger call center. You buy campaigns that the team runs for you, each built around one clear goal and quoted before launch. For MSPs, the Win-Back & Reactivation Calling campaign typically targets clients dormant for 12 to 24 months, which lines up well with the way IT contracts lapse and renewal cycles roll. The Database Reactivation Blitz Campaign runs structured multi-touch outreach across calls, texts, and emails over two to four weeks, useful for working a larger list of past clients and stalled proposals in one push. Outcomes route back into the CRM and scheduling tools you already use, and hot leads transfer to your team live or land in your CRM. What sets this provider apart is list discipline. List source and consent records are checked before any campaign launches. Bought lists without clear permission records are flagged and, in most cases, declined. You're told plainly if a list won't support the campaign before you spend anything. Compliance is built in: AI voices are treated as artificial voices under the TCPA with prior express consent required, state-specific quiet hours are honored, AI disclosure happens on every call, and opt-outs are logged and honored immediately. Reporting shows what actually happened, with disposition codes, per-call notes, and no invented numbers.

Best for: MSPs that want a hands-off, compliance-first way to reactivate dormant clients and stalled deals without hiring call center staff or buying another software platform.

#2 CallMyCustomers — One-time campaign setup fee based on list size (quoted at the free list review); outreach minutes from 9¢ to 21¢ per minute depending on monthly volume. Texts and emails are included in the quote, with no per-seat software fees.

CallMyCustomers is a done-for-you customer reactivation, retention, and repeat-revenue service built for US service businesses. According to its website, the core premise is that your next booked client probably already knows you. They may be a former client whose contract ended, a prospect that inquired but never moved forward, or a referral source that went quiet. For MSPs sitting on a list of past project clients and lapsed agreements, that framing fits well. The service works from whatever you already have. A CRM, a spreadsheet, or a point-of-system list, exactly as it is, with no new software to buy or learn. What distinguishes CallMyCustomers is its approval-first model: you sign off on every script, offer, and message before anything is sent, so outreach always reflects your voice and standards. Outreach is handled by real people making calls on your behalf, with texts and emails sent in your name. Automation handles scale and humans handle judgment. According to the company, win-back campaigns typically run two to four weeks end to end, with replies coming in as soon as the first outreach wave goes out, and replies route directly into your booking and intake process. Lists are segmented by recency, past inquiries that never converted, and satisfied past clients who could provide reviews or referrals.

Best for: MSPs that want a hands-off, done-for-you win-back service run by real people, with full approval control over every message.

#3 WinbackEngine — $1,000 commitment fee to start a 30-day pilot, plus 20% of net recovered revenue billed weekly. The fee is refunded in full if 5x ROI is not achieved in 30 days (as of September 2026).

WinbackEngine is a performance-based customer reactivation service that uses trained human agents to call lapsed customers on behalf of multi-location service businesses. According to a 2026 review by SyncGTM, the service targets categories like fitness studios, med spas, and dental practices, which share the same dynamics MSPs face: lapsed clients, repeat-visit economics, and booking-based revenue. The process runs in four steps. First, you connect your booking system or CRM. Integrations include Zenoti, Mindbody, Vagaro, WellnessLiving, Booker, Fresha, Phorest, and MarianaTek, or a CSV or API export. Second, the team builds tailored campaigns and call scripts. Third, agents are trained on your brand voice. Fourth, calls go out and customers rebook. The company states these are not robocalls or generic scripts. Each agent is briefed on your business, your services, and common reasons customers leave, then makes personalized calls to get lapsed clients back. Most clients see bookings within 7 days of launch, according to the company. The performance-based model aligns incentives. As of September 2026, WinbackEngine asks for a $1,000 commitment fee to start a 30-day pilot, charges 20% of net recovered revenue billed weekly, and refunds the fee in full if it doesn't hit 5x ROI in 30 days. Note the eligibility gates: the service looks for businesses with 500+ lapsed customers and a $50+ average transaction, so smaller MSPs may not qualify.

Best for: Larger multi-location service businesses with 500+ lapsed customers who want to pay only for recovered revenue.

#4 Telecom Inc. — Contact for pricing. The company offers month-to-month plans with pay-per-appointment or hourly rates and tailored packages.

Telecom Inc. is an outbound contact services provider that specializes in executing targeted win-back campaigns to reconnect businesses with lapsed or inactive customers. According to its website, the team crafts personalized strategies that re-engage prospects, moving them back into the sales pipeline and boosting revenue. The company reports experience running win-back campaigns across industries, from e-commerce to service-based businesses, which makes it a reasonable fit for an MSP working a list of former clients. The process is straightforward. First, Telecom identifies customers who haven't interacted or purchased within a set time frame. Second, the team crafts customized win-back messages based on your business and customer insights. Third, outreach runs across phone, email, SMS, and live chat to maximize engagement. Fourth, every interaction is tracked through your CRM, with integrations for platforms like Salesforce and HubSpot for seamless follow-up. On pricing, the company describes a cost-effective, flexible structure that scales with appointment volume and outreach requirements. Month-to-month service plans mean no long-term commitments, and you can choose pay-per-appointment or hourly rates with tailored packages for your industry. Clients quoted on the site highlight Telecom's responsiveness and data-driven reporting. For an MSP that wants a traditional human-agent outbound partner with flexible commercial terms, Telecom is worth a conversation.

Best for: MSPs that want a traditional human-agent outbound partner with flexible, month-to-month commercial terms.

#5 MarketStar — Contact for pricing.

MarketStar is an outsourced customer success and sales organization that offers dedicated Win-Back and Reactivation services. According to its website, the company views lapsed customers not as losses but as opportunities for a comeback, and existing customers make up 60-70% of a company's sales. For an MSP with a meaningful book of former clients, that's the same math that makes reactivation worth doing. The approach starts with segmentation. MarketStar identifies and categorizes lapsed customers by value, reasons for leaving, and potential for reactivation, then analyzes feedback, product usage patterns, and competitive factors to understand why each group went quiet. From there, the team crafts tailored reactivation campaigns that address the identified reasons for departure, highlighting new offerings, improvements, or incentives. Outreach is multichannel, reaching customers through email, direct mail, phone calls, and social media. Once customers express interest, MarketStar engages in proactive re-engagement and ongoing relationship management so reactivated customers transition back smoothly. Real-time monitoring tracks reactivation rates, customer feedback, and revenue impact, with ROI analysis to evaluate the cost-benefit ratio. The company also runs seasonal and event-based initiatives and loyalty reward programs. This is an enterprise-oriented partner, best suited to MSPs with enough lapsed-account volume to justify an outsourced program rather than a single campaign.

Best for: MSPs and multi-location organizations with substantial lapsed-account volume that want a full outsourced reactivation program rather than a one-off campaign.

Win-back and reactivation calling is one of the highest-ROI moves an MSP can make in 2026. You already paid to acquire every contact in that dormant list, and a single recovered managed services contract can be worth tens of thousands of dollars a year. The right provider depends on your volume and how hands-off you want to be. My AI Call Center is our Editor's Choice for its list discipline, compliance-forward process, and transparent per-minute pricing starting at 9¢ per connected minute, with the full campaign quoted before you spend anything. CallMyCustomers suits MSPs who want human callers with approval control over every message. WinbackEngine fits larger operations comfortable with performance-based fees. Telecom Inc. and MarketStar round out the list for flexible month-to-month or enterprise-scale programs. Start with a free campaign review, confirm your list has consent records behind it, and pick the partner whose model matches how you want to pay. Your next client is probably already in your CRM.
