Top 5 Win-Back & Reactivation Calls for IT Staffing Agencies

Every IT staffing agency has the same quiet problem: a database full of placed candidates and former clients who haven't heard from the firm in a year or more. The math favors working that list over chasing strangers. Re-engagement outreach to people who have worked with you before converts at 8 to 15 percent, according to industry data compiled by US Tech Automations, versus 1 to 3 percent for cold outreach. Firms running systematic win-back automation recover an average of 12 to 18 percent of lapsed contacts into active conversations within 90 days. The catch is that most recruiting teams never touch the dormant list systematically, because recruiters are busy filling today's reqs. Phone outreach is the strongest channel for this work. Agencies that use the phone to maintain relationships show repeat business rates roughly 20 percent higher, according to Bullhorn's GRID report. This guide ranks five platforms and services that help IT staffing firms turn dormant candidates and cold client accounts back into live conversations, including one managed service that runs the whole campaign for you.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign. Most campaigns add a one-time setup and a flat monthly management fee, both quoted before launch. The first campaign review is free.

My AI Call Center is a done-for-you managed outbound calling service, owned and operated by AIQ Labs out of Halifax, Nova Scotia, with a US operating base in Austin, Texas. The key difference from everything else on this list: you don't buy software and figure it out. You buy campaigns that they run for you. Each campaign is scoped around one clear goal, quoted in full before launch, and executed against approved, permissioned, or reviewed contact lists only. For an IT staffing agency sitting on thousands of dormant candidates and lapsed client contacts, that matters, because the service will tell you plainly if your list won't support the campaign before you spend anything. Bought lists without clear permission records get flagged, and in most cases declined. The service offers two campaign types that map directly onto staffing win-back work. Win-Back & Reactivation Calling targets contacts who have typically been dormant 12 to 24 months, which lines up with the lapsed candidate and cold client segments most IT staffing firms carry. Database Reactivation Blitz Campaigns run a structured multi-touch sequence across calls, texts, and emails over two to four weeks for firms that want a heavier push. The process is disciplined: campaign review, list and consent review, system connection, script and escalation approval, then launch. Nothing goes live until you approve the script, the disclosure language, the opt-out handling, and the escalation path. Hot leads transfer to your team live or land in your CRM, and outcomes route back into the scheduling and CRM tools you already run. Compliance is treated as a feature, not an afterthought. AI voices are treated as artificial voices under the TCPA, with prior express consent required. Every call includes AI disclosure, and recipients can ask for a human or opt out with keywords like STOP or REVOKE. You get a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, routed follow-ups, and completion and coverage reports. The company's stated policy is no invented numbers: they report what actually happened.

Best for: IT staffing and recruiting firms that want structured win-back calling against their own permissioned candidate and client lists without building an internal calling operation.

#2 Gem — $5,000-$12,000 per year depending on team size, according to the research.

Gem is a candidate CRM and sequencing platform built specifically for recruiting. It sits on top of your ATS and LinkedIn, which is exactly where IT staffing firms live. According to the research, Gem lets you build a segment such as "last active 12-24 months ago, placed in a skill category" and run a four-step sequence across LinkedIn InMail and email automatically. The recruiter personalizes the first message and the follow-up touches are automated, which fits the reality that most staffing teams can't hand-write hundreds of re-engagement notes. Responses route back to the owning recruiter's Gem inbox, synced with their ATS, so a lapsed candidate who replies lands with the person who has context rather than a generic company inbox. That routing step is what separates a real win-back system from an email blaster. Gem integrates with Greenhouse, Lever, and Workday. Personalized passive-candidate outreach referencing a prior role or skill set can reach InMail acceptance rates of 30 percent or higher, versus 18 to 22 percent for standard recruiter messages, per LinkedIn Talent Insights data cited in the research. The honest limitation: Gem is candidate-focused. Client win-back, meaning re-engaging former hiring managers who stopped sending roles, is not its primary design use case, so firms with a business development function will need a separate CRM sequence tool for that side of the house.

Best for: IT staffing and search firms with 5+ recruiters doing active sourcing who want automated candidate re-engagement sequences.

#3 Loxo — $119-$179 per user per month, according to the research.

Loxo combines an ATS, a CRM, and an outreach sequencer in a single platform. For smaller IT staffing firms that haven't separated those systems, it offers the fastest path to a working win-back workflow without stitching together multiple vendors. According to the research, Loxo's "people intelligence" layer scores candidates by recency and relevance, and a filter for candidates last contacted 12 to 18 months ago in a given skill category produces a win-back segment in minutes. For IT staffing, where skill categories like cloud, security, or data engineering matter a lot, that kind of filtering is practical. The outreach module sends email sequences from the recruiter's own email address with automatic follow-up scheduling, which keeps the re-engagement personal rather than corporate. Pricing runs $119 to $179 per user per month, which the research notes is competitive for teams of 3 to 10 recruiters. That makes Loxo a realistic option for boutique IT staffing shops that can't justify a Gem plus Bullhorn stack. The trade-off is redundancy if you already run Greenhouse or Lever as your ATS. In that case, the research suggests a sequencing-only tool integrates better, and you'd be paying for an ATS you don't need. Like Gem, Loxo's sequences are email-based; there's no calling layer for the contacts who don't answer email.

Best for: Boutique IT staffing firms of 3-10 recruiters that want ATS, CRM, and outreach in one product.

#4 Herefish by Bullhorn — Bundled with Bullhorn Enterprise licensing. Standalone pricing varies by firm size; contact Bullhorn for current rates.

Herefish is an automation and engagement platform built specifically for Bullhorn ATS users. If your IT staffing firm runs Bullhorn, this is the most tightly integrated win-back option available, full stop. According to the research, Herefish reads directly from Bullhorn's candidate and contact records, identifies lapsed contacts by date-last-contacted, and runs multi-step email and SMS sequences without any data export. The trigger fires from Bullhorn itself: a candidate record whose date_last_updated passes a threshold automatically enters the win-back sequence. That live-data approach matters. Most win-back efforts fail because someone exports a stale CSV, calls or emails it, and half the contacts have moved on. Herefish works from the ATS of record, so the segment stays current. It also supports both candidate and client contact sequences in one platform, which covers the two distinct win-back workflows staffing firms need: lapsed candidates on one side, former hiring managers on the other. The limitation is equally clear. If you're not on Bullhorn, Herefish isn't useful, and its value outside the Bullhorn ecosystem is limited. Pricing is bundled with Bullhorn Enterprise licensing, with standalone pricing varying by firm size, so you'll need to contact Bullhorn for current rates.

Best for: IT staffing firms already running Bullhorn that want zero-friction, ATS-triggered win-back automation.

#5 WinbackEngine — $1,000 to start a 30-day pilot, plus 20% of net recovered revenue billed weekly, with the fee refunded if 5x ROI isn't hit in 30 days (as of September 2026).

WinbackEngine is a performance-based reactivation service that deploys trained human agents to call lapsed customers on your behalf. It's built for multi-location service businesses like fitness studios, dental practices, and med spas rather than staffing firms specifically, but the model is worth understanding if your agency wants outsourced calling with aligned incentives. According to the research, agents are briefed on your business and offerings, trained on your brand voice, and make personalized calls to get lapsed contacts to rebook or renew. It integrates with booking systems including Zenoti, Mindbody, Vagaro, and others, or takes a CSV or API export. The pricing model is the interesting part. As of September 2026, a 30-day pilot starts at $1,000, the service keeps 20 percent of net recovered revenue billed weekly, and it refunds the fee in full if it doesn't hit 5x ROI in 30 days. That aligns incentives, but note the eligibility gates: WinbackEngine looks for businesses with 500+ lapsed customers and a $50+ average transaction. There's also a structural ceiling, since a churned list is finite, and the service is reactive by design. It recovers revenue that already left; it doesn't help you prevent the next lapse. For an IT staffing firm with a large dormant candidate base, it could work, but the service-business focus means the fit isn't native.

Best for: Multi-location service businesses with 500+ lapsed customers and $50+ average transactions that want outsourced human calling on a performance basis.

The pattern across all five options is that win-back works best when it's systematic. Firms running structured re-engagement recover 12 to 18 percent of lapsed contacts into active conversations within 90 days, and phone outreach consistently outperforms email for this work. If your IT staffing firm runs Bullhorn, Herefish deserves a look first because the automation runs on live ATS data. Gem and Loxo are strong if your win-back is primarily candidate-focused email and InMail sequencing. WinbackEngine shows what outsourced human calling looks like on a performance basis, though it's built for service businesses rather than staffing. If what you actually want is someone to run structured, compliance-forward reactivation calls against your own permissioned candidate and client lists, start with My AI Call Center. The first campaign review is free, calling starts at 9¢ per connected minute with the rate locked, and the full cost is known before anything launches.
