Every HR outsourcing firm has the same quiet problem: a CRM full of past clients, placed candidates, and lapsed staffing accounts who worked with you once and then went quiet. They didn't leave because they were unhappy. Most of them got busy, changed roles, or drifted to whichever provider picked up the phone first. Industry research on reactivation is consistent on the economics: winning back a lapsed customer costs a fraction of acquiring a new one, because the trust and service history already exist. The catch is execution. Working a dormant list takes calls, scripts, consent discipline, and hours your recruiters don't have while they're mid-search. That's why win-back campaigns get pushed to next quarter, forever. This 2026 guide compares three providers that help HR outsourcing firms run structured reactivation calls against their own past-client and past-candidate lists, whether through a fully managed service or an AI agent you deploy yourself. We ranked them on list discipline, compliance handling, reporting transparency, and fit for staffing operations where relationships carry long shelf lives.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time campaign setup fee and a flat monthly management fee, both quoted before launch. 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. Never indiscriminate cold calling. Owned and operated by AIQ Labs and based in Halifax, Nova Scotia, with a U.S. operating base in Austin, Texas, the service is built around one promise: run more useful calls without building a bigger call center. For HR outsourcing firms sitting on a dormant book of past clients and placed candidates, the Win-Back & Reactivation Calling campaign typically targets contacts who haven't been active in 12 to 24 months, and it pairs naturally with Recruitment & Screening and Lapsed Member Re-Engagement campaigns when you want to cover both sides of the staffing relationship. Database Reactivation Blitz campaigns run as structured multi-touch pushes across calls, texts, and emails over two to four weeks when you want a bigger seasonal recovery effort. What sets My AI Call Center apart is list discipline and honesty. Before any campaign launches, list source and consent records are reviewed, and bought lists without clear permission records are flagged and, in most cases, declined. As the company puts it, they tell you plainly if the list will not support the campaign, before you spend anything. You buy campaigns that are run for you, each scoped around one clear goal, quoted in full before launch. There are no per-seat charges, no platform bill, and no minimums you did not choose. Outcomes route back into the CRM and scheduling tools you already run, so hot leads transfer to your team live or land in your CRM, and every campaign ends with a named outcome report containing disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and routed follow-up requests. Your recruiters only work the re-engaged contacts. Compliance is treated as a feature, not an afterthought. AI-generated voices are treated as artificial voices under the TCPA, with prior express consent required. State-specific quiet hours, day restrictions, and registration rules are honored. AI disclosure appears on every call, and recipients can ask if the call is AI-assisted, request a human, or opt out. Keyword opt-outs like STOP and REVOKE are logged and honored immediately, and DNC requests carry across all campaigns. The company commits to no invented numbers: they report what actually happened, never inventing client logos, testimonials, metrics, or ratings. Calling starts at 9¢ per connected minute, tiered by volume, with the rate agreed before launch and locked for the campaign. Most campaigns add a one-time setup and a flat monthly management fee, both quoted before launch, and the first campaign review is free.
Pros
- Fully managed service with the full price known before you approve launch, and rates locked for the campaign
- Strict list and consent review protects against TCPA risk before any money is spent
- Dispositioned outcome reports mean your team only works re-engaged contacts
- Compliance-forward: AI disclosure on every call, immediate opt-out handling, DNC carried across campaigns
- Commits to honest reporting with no invented metrics or testimonials
Cons
- Requires you to provide your own contact list for review
- Not a self-serve software platform; campaigns are run by the provider
- Launch timing depends on list review and your approval cycle
- Clients are responsible for obtaining appropriate legal guidance before launch
Best for: HR outsourcing firms and staffing operations with 1–200+ staff who want a fully managed, compliance-forward reactivation calling program run against their permissioned past-client and past-candidate lists, without hiring call center staff or babysitting software.
#2 OnBrand24 — Contact for pricing
OnBrand24 provides customer win-back call center services focused on re-engaging inactive customers through research-driven, outbound calling campaigns. According to their website, the company begins each engagement by conducting thorough research on the client's customer base to determine the reasons for churn and identify any product or service issues that may have contributed to disengagement. This diagnostic approach allows OnBrand24 to tailor campaigns not just to re-establish contact, but to address underlying concerns that caused the lapse in the first place. For an HR outsourcing firm, that matters: the reason a client stopped sending roles is often specific, and a script that ignores it won't land. Their representatives are described as highly trained agents who call through hundreds or thousands of existing accounts to re-open conversations, generate updated customer data, and execute appointment setting programs. A key outcome highlighted in their case studies is the hand-off of closeable leads directly to the client's inside sales team for immediate follow-up. OnBrand24 emphasizes delivering at an impressively low per-opportunity rate through maximized efficiency, positioning the service as a cost-effective alternative to acquiring new customers. The company reports re-engaging over 3,000 inactive customers in a single national campaign and identifying nearly 1,000 closeable leads referred to inside sales, with 50-state coverage in that campaign. Their process includes database scrubbing and updates with every dial, so CRM data stays current, and campaigns scale from hundreds to thousands of accounts without adding client headcount. Complementary services include B2B list/database scrubbing, market research, and lead generation that can be paired with win-back efforts to improve data quality and sales readiness.
Pros
- Focuses on understanding why customers left before re-engaging
- Generates updated customer data during every campaign
- Provides direct sales hand-off of closeable leads
- Scales efficiently without requiring the client to add headcount
- Offers complementary services like database scrubbing and market research
Cons
- Pricing not publicly disclosed, requiring custom quotes
- Relies on human agents rather than AI-assisted calling
- May involve higher labor costs compared to automated solutions
- Less emphasis on AI-driven personalization at scale
Best for: B2B firms, including HR outsourcing and staffing companies, that want research-backed win-back campaigns with lead hand-off to internal sales teams, especially those wanting database cleanup alongside reactivation efforts.
#3 Telecom Inc. — Choose from pay-per-appointment or hourly rates; month-to-month service plans. Contact for specific pricing.
Telecom Inc. offers targeted win-back campaigns designed to help businesses reconnect with lapsed or inactive customers through personalized, multi-channel outreach. According to their website, their approach begins with identifying customers who have not interacted or purchased within a set time frame, followed by crafting personalized messages based on business and customer insights. The company emphasizes a multi-channel strategy that connects through phone, email, SMS, and live chat to increase the chances of re-engagement. For HR outsourcing firms whose past clients live across different channels and time zones, that breadth of coverage is genuinely useful: a hiring manager who ignores email may still pick up a call. Their stated advantages include targeted outreach to lost customers, personalized messaging with exclusive deals or updated offerings, CRM integration with platforms like Salesforce and HubSpot for seamless tracking and follow-up, and a data-driven strategy that uses past customer data and insights to craft an outreach approach with the highest conversion potential. The process is straightforward: identify lost customers, craft personalized campaigns based on business and customer insights, run multi-channel outreach, then track and follow up through your CRM so every interaction is logged and consistent. Telecom Inc. positions its campaigns as customizable to a business's goals and audience, with experience executing win-back work across industries from e-commerce to service-based businesses. On pricing, the company offers month-to-month service plans with pay-per-appointment or hourly rate options, tailored packages by industry and objective, and clear, detailed reporting and analytics, with no long-term commitments described on their site.
Pros
- Multi-channel approach reaches customers through their preferred communication channels
- Month-to-month plans with pay-per-appointment or hourly pricing flexibility
- CRM integration with Salesforce and HubSpot for consistent follow-up
- Customizable campaigns tailored to specific industries and objectives
- Clear reporting and analytics on campaign performance
Cons
- Pricing not published publicly; requires a consultation for specific rates
- Results described in general terms rather than published benchmark figures
- Multi-channel scope may be broader than firms that only need phone-based reactivation
- Onboarding requires brand setup before campaigns launch
Best for: Growing businesses, including HR outsourcing firms, that want flexible month-to-month win-back campaigns with multi-channel outreach and CRM-integrated tracking without long-term commitments.
Picking a win-back partner for an HR outsourcing firm comes down to how much control you want over the calling operation and how much compliance weight you're carrying.

Both are solid options for firms with the budget and appetite for hands-on program management.

Frequently asked questions
What makes My AI Call Center different from other win-back providers?
Three things separate it. First, it's a managed service rather than software: you buy campaigns that are run for you, each scoped around one clear goal and quoted in full before launch. Second, list discipline is enforced as a gate: only approved, permissioned, or reviewed contact lists are used, and bought lists without clear permission records are flagged and, in most cases, declined before you spend anything. Third, reporting is honest and dispositioned. Every campaign ends with a named outcome report containing disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and routed follow-up requests, and the company commits to never inventing client logos, testimonials, metrics, or ratings.
How do win-back calls work for HR outsourcing firms specifically?
For HR outsourcing and staffing firms, reactivation usually targets two groups: past clients who haven't sent a role in 12+ months, and placed candidates or contacts who've been dark for a similar window. My AI Call Center's Win-Back & Reactivation Calling campaign is built for that 12 to 24 month dormant range, and it can be paired with Recruitment & Screening or Lapsed Member Re-Engagement campaigns depending on which side of the relationship you're working. Each campaign is scoped around one clear goal (confirm, qualify, remind, survey, retain, or connect), and outcomes route back into the CRM and ATS tools your recruiters already use.
What does win-back calling typically cost in 2026?
It varies by model. My AI Call Center prices calling from 9¢ per connected minute, tiered by volume, with most campaigns adding a one-time setup fee and a flat monthly management fee, all quoted before launch and the rate locked for the campaign. OnBrand24 and Telecom Inc. don't publish specific rates; OnBrand24 requires a custom quote and Telecom Inc. offers pay-per-appointment or hourly rates on month-to-month plans. For self-serve AI tools in the broader market, published prices run from $349 to $449 per month at the low end (per Iterategy's 2026 review of 13 win-back agent products), though many vendors price on revenue share or per booking and don't publish rates at all.
Do reactivation calls to past clients and candidates need consent under the TCPA?
The rules depend on your contact type, consent history, location, and the technology you use, so get legal guidance for your specific situation before launching. That said, how a provider handles compliance is a real differentiator. My AI Call Center treats AI-generated voices as artificial voices under the TCPA and requires prior express consent, honors state-specific quiet hours and day restrictions, discloses AI on every call, and logs keyword opt-outs like STOP and REVOKE immediately. If you're comparing vendors, ask each one directly about consent review, quiet hours, DNC handling, and what happens to your data after the campaign ends.
Should HR outsourcing firms use a managed calling service or a self-serve AI agent?
It depends on who's going to run the campaign. A managed service like My AI Call Center makes sense when you want the calling handled end to end and your recruiters to only work the re-engaged contacts. A self-serve AI agent makes sense when you have someone internally who'll own setup, testing, script iteration, and CRM configuration. Most HR outsourcing firms we see are better served by managed service because recruiter time is expensive and compliance risk on dormant lists is real. Whichever route you pick, insist on seeing how list review, consent checks, and outcome reporting work before you sign anything.
How long does a win-back campaign take to show results?
It depends on list size, dormancy window, and how many touches the campaign runs. My AI Call Center's Database Reactivation Blitz campaigns run two to four weeks as structured multi-touch pushes across calls, texts, and emails, while single-goal Win-Back & Reactivation Calling campaigns are scoped and quoted before launch with a defined coverage window. What matters more than speed is what you get back: a dispositioned contact list, outcome counts, routed follow-ups, a completion and coverage report, and opt-out/DNC logs. If a provider can't tell you exactly what deliverables you'll receive, that's a signal to keep looking.
What should I check before launching a reactivation campaign against a dormant list?
Start with list source and consent records. Dormant HR and staffing databases often have unclear opt-in status, especially records inherited from prior systems or bought lists. My AI Call Center reviews list source, consent records, and calling windows before any campaign launches, and tells you plainly if the list won't support the campaign before you spend anything. Beyond that, confirm how the provider handles opt-outs and DNC requests (they should be honored immediately and carried across campaigns), whether AI disclosure appears on every call, and whether your data is ever shared, sold, or used to train shared models.
