Executive search firms live and die by relationships, and lapsed relationships are expensive. When a former client, candidate, or network member stops engaging, most firms send one email and move on. That's a missed opportunity. Research from Annex Cloud, cited by Personify, suggests a 5% increase in retention can boost profits by 25% to 95%, and about 65% of a company's business comes from repeat customers. A phone call does something email can't: it surfaces the real reason someone drifted away, whether that's a bad experience, a leadership change, or they simply forgot. PropFuel found that 53% of responding lapsed members didn't even realize their membership had lapsed. For search firms running retained engagements, alumni networks, or membership-style talent communities, structured re-engagement calling can revive dormant revenue without building an internal call center. This guide ranks four solutions that help you run those campaigns compliantly and with clear reporting, starting with our Editor's Choice.
#1 My AI Call Center — Calling starts at 9 cents per connected minute, tiered by volume; most campaigns add a one-time setup fee and flat monthly management fee, both quoted before launch. First campaign review is free.
My AI Call Center is a done-for-you managed outbound calling service from AIQ Labs, based in Halifax, Nova Scotia, with an operating base in Austin, Texas. You buy campaigns that the team runs for you, each scoped around one clear goal and quoted before launch. For executive search firms, the Lapsed Member Re-Engagement campaign type fits alumni networks, retained-client databases, and talent communities where past contacts have gone quiet. Win-Back and Reactivation Calling typically targets 12 to 24 month dormants, so you can segment recent lapses from long-term ones and message each group differently. What sets this service apart is list discipline. Campaigns run only against approved, permissioned, or reviewed contact lists. The team checks list source and consent records before anything launches, flags bought lists without clear permission records, and in most cases declines them. If your list won't support the campaign, they tell you plainly before you spend anything. That matters in search, where your reputation with candidates and clients is the asset. Pricing starts at 9 cents per connected minute, tiered by volume, with a one-time campaign setup and flat monthly management fee quoted up front. The rate is locked for the campaign. Outcomes route back into your CRM with disposition codes, per-call notes, and follow-up requests, and hot leads can transfer to your team live. The company reports what actually happened and will not invent client logos, testimonials, metrics, or ratings.
Pros
- Done-for-you managed service, so no software to learn or seats to pay for
- Consent and list review happens before you spend anything
- Pricing is fully known before launch and locked for the campaign
- Detailed disposition reporting rather than vague activity counts
- Compliance-forward handling of TCPA artificial voice rules and opt-outs
Cons
- It's a managed service, so you depend on the provider's team rather than running campaigns yourself
- Setup and management fees vary by campaign, so budgets require a quote
- Campaigns are scoped to one clear goal each, which may mean multiple campaigns for complex win-back programs
Best for: Executive search firms and membership-based talent organizations that want a managed calling partner with strict consent standards and transparent outcome reporting, without hiring an internal call team.
#2 B2B Appointment Setting — Contact for pricing
B2B Appointment Setting offers lapsed member re-engagement calling as part of its customer reactivation services, and its public scope guide is unusually candid about what a good program requires. According to their website, these calls seek to understand inactivity and establish an authorized next step, shaped by membership type, contact preferences, and any unresolved issues. That framing fits executive search well, because a lapsed contact at a client company often has a specific reason for going quiet, and a renewal pitch alone can miss it. Their planning guidance asks you to define what counts as lapsed, exclude inappropriate records, and record reasons, preferences, and follow-up ownership before launch. They also walk through a review scenario where a member stopped participating because a support issue stayed open, and the caller routes the issue to its owner instead of pushing renewal. For search firms, the equivalent is routing a stalled mandate or a changed hiring contact to the right partner on your team. Measurement advice is practical: track resolved barriers, accepted follow-up, and sustained participation, since a positive conversation alone is not a completed reactivation. They recommend bringing a small representative set of tasks and current instructions to a pilot review, and agreeing on acceptable handling before volume increases. Pricing is not published; you request a consultation to confirm whether the proposed work fits their offering.
Pros
- Thoughtful, published scope methodology that reduces campaign misfires
- Emphasis on understanding why members lapsed, not just pushing renewal
- Clear exception and escalation guidance
- Measurement advice focused on real reactivation, not call counts
Cons
- No published pricing, so budgeting requires a consultation
- Heavy documentation requirements may feel slow for smaller firms
- The scope guide is planning material; actual qualifications and terms must be confirmed with the provider
Best for: Firms that want a consultative B2B calling partner and are willing to invest in detailed scope documentation before launch.
#3 PropFuel — Contact for pricing (demo required)
PropFuel is a conversational engagement platform built for member-based organizations, using an Ask, Capture, Act methodology across email and SMS. While it isn't a calling service, it earns a spot here because its published win-back results show how structured, question-first outreach revives lapsed members at scale, and its check-in sequences pair naturally with phone follow-up for high-value contacts. The results are specific. The Association of Legal Administrators enrolled 1,841 recently lapsed contacts; 715 (39%) engaged, and all-time campaign renewals reached 1,118, or 61% of enrolled contacts. The American Academy of Pediatrics reported 2,027 reinstated members with an 80% win-back rate from its engagement efforts. INCOSE reinstated over a thousand members across categories between September 2022 and December 2023. A PropFuel client study also found that 53% of responding lapsed members in 2022 didn't know their membership had lapsed, which is exactly the kind of insight a short check-in question surfaces. For an executive search firm running a membership or alumni program, PropFuel's approach means asking lapsed contacts what would bring them back, capturing the answers, and acting on them. SMS reminders at grace-period milestones, demonstrated with the American Psychiatric Association, reduce avoidable lapses in the first place. Pricing is not published on the site; you request a demo to get terms.
Pros
- Published, specific client results with engagement and renewal percentages
- Surfaces the real reasons members lapse, including simple forgetfulness
- SMS timing at renewal milestones prevents avoidable lapses
- Built specifically for member-based organizations
Cons
- Email and SMS focused, so live calling must be handled separately or by your team
- No published pricing
- Best fit for structured membership programs rather than one-off client win-back lists
Best for: Membership organizations and search firms running formal member or alumni programs that want question-driven win-back campaigns with strong response data.
#4 ReferWell — Contact for pricing
ReferWell approaches member engagement through proactive outbound phone calls delivered by its Care Navigators, supported by a care scheduling platform. It is healthcare-specific, so it won't fit every executive search firm, but it's included because its published evidence makes the strongest case in this research set for why phone calls outperform digital channels in member re-engagement, and because search firms serving healthcare clients will recognize the environment. According to their website, 88% of healthcare appointments are still scheduled by phone, and a recent survey they cite found 82% of people accept an appointment when approached through a call. Their model pairs consistent outreach with relationship continuity: the same Care Navigator calls a member over the course of a year, from welcome calls and wellness scheduling to Health Risk Assessments and overdue screening follow-ups. Their published example describes a member whose follow-up call led to an early-stage heart disease diagnosis, illustrating how repeated, familiar contact changes outcomes. ReferWell reports a claims-validated 242% ROI and positions its service around improved HEDIS measures, CAHPS scores, and Star ratings for health plans. For an executive search firm with a healthcare practice or a health-plan client, the takeaway is transferable: assign a consistent caller, call on a schedule across the year, and treat each call as a conversation rather than a reminder. Pricing is not published.
Pros
- Strong published evidence for phone-based engagement effectiveness
- Consistent-caller model builds trust over time
- Scheduling capability closes the loop from call to booked appointment
- Claims-validated ROI figure supports budget conversations
Cons
- Healthcare-specific, so not a direct fit for general executive search win-back lists
- No published pricing
- Model is built around care navigation, not recruiting or membership renewal workflows
Best for: Healthcare practices and health plans, plus executive search firms serving healthcare clients that want a proven model for phone-based member re-engagement.
Lapsed contacts are the cheapest growth available to an executive search firm. They already know you, they're already in your database, and a well-run call can surface exactly why they went quiet. The four options above cover different needs: My AI Call Center if you want a managed calling partner with strict consent standards and full campaign pricing known before launch; B2B Appointment Setting if you want a consultative scope process; PropFuel if you run a formal membership program and want question-driven email and SMS win-back campaigns; and ReferWell if your work sits in healthcare. Start small. Pick one segment, say members lapsed 12 to 24 months, define what a successful outcome looks like, and run a pilot. My AI Call Center's first campaign review is free, so you can scope a re-engagement campaign, see the full quote, and decide without risk. Plan your campaign at myaicallcenter.app and find out what your dormant list is actually worth.
Frequently asked questions
Why phone calls instead of email for lapsed member re-engagement?
Email win-back campaigns are easy to ignore, and many lapsed contacts never open them. PropFuel's client study found that 53% of responding lapsed members in 2022 didn't even know their membership had lapsed, which means the message never landed as a decision at all. A call creates a real conversation where you can ask what changed, address a specific concern, and establish an authorized next step. ReferWell's research notes that 82% of people accept an appointment when approached through a phone call. For high-value contacts like former clients or senior candidates, the personal channel matches the relationship.
What makes My AI Call Center different from other calling services?
Three things. First, it's a managed service, not software: you buy campaigns the team runs for you, each with one clear goal, quoted before launch. Second, list discipline: campaigns run only against approved, permissioned, or reviewed lists, and consent records are checked before launch. Bought lists without clear permission are flagged and usually declined, and you're told plainly if your list won't support the campaign before you spend anything. Third, reporting: you get dispositioned contact lists, outcome counts, routed follow-ups, and opt-out logs, and the company will not invent metrics or testimonials. Pricing starts at 9 cents per connected minute with no per-seat charges.
How should an executive search firm segment a lapsed contact list before calling?
Follow the segmentation logic common across the research. Separate contacts lapsed within the past 12 to 24 months from those lapsed longer, since messaging differs. My AI Call Center's win-back campaigns typically target 12 to 24 month dormants. Then layer in the reason for lapsing where you know it: a stalled mandate, a leadership change at the client, a candidate who took a role, or simple forgetfulness. A contact who left over price needs a different conversation than one who had an unresolved issue. Exclude any records where consent status is unclear before the list goes to a calling partner.
What compliance rules apply to AI-assisted re-engagement calls?
My AI Call Center treats AI-generated voices as artificial voices under the TCPA, which means prior express consent is required before calling. State-specific quiet hours, day restrictions, and registration rules are honored, every call includes AI disclosure so recipients can ask if the call is AI-assisted, request a human, or opt out, and keyword opt-outs like STOP and REVOKE are honored immediately. DNC requests are respected across all campaigns and carried into client DNC records. Requirements vary by location, industry, contact type, and consent status, so clients should obtain appropriate legal guidance before launch.
How do I measure whether a re-engagement campaign actually worked?
B2B Appointment Setting's guidance is a good benchmark: track resolved barriers, accepted follow-up, and sustained participation, because a positive conversation alone is not a completed reactivation. In practice that means counting contacts who renewed, re-engaged, or accepted a concrete next step like a meeting, not just answered calls. My AI Call Center delivers named outcome reports with disposition codes (confirmed, qualified, renewed, opted out, no answer) plus per-call notes and routed follow-ups, so you can tie outcomes to your CRM. Review the underlying records, not just the summary, and keep the evaluation period consistent.
What does a campaign like this cost?
My AI Call Center's calling starts at 9 cents per connected minute, tiered by volume, with the rate locked for the campaign. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch, so the full number is known before you approve. There are no per-seat charges, no platform bill, and no minimums you didn't choose, and the first campaign review is free. B2B Appointment Setting, PropFuel, and ReferWell do not publish pricing, so you'll need a consultation or demo to get terms from them.
Can we run re-engagement calls in-house instead?
You can, and some associations do exactly that; YM Careers describes board and staff dividing a call list and calling lapsed members directly. In-house calling works at small volume and gives you full control of the conversation. The tradeoffs are capacity, consistency, and compliance. Managed services like My AI Call Center handle calling windows, disclosure scripts, opt-out logging, and outcome routing as part of the campaign, which matters once your lapsed list grows past what a partner or associate can work through between searches. A reasonable path is a managed pilot first, then decide whether to bring volume in-house.
