Top 7 Win-Back & Reactivation Calls Providers for Conference & Trade Show Organizers

Trade show and conference organizers sit on a quiet goldmine: past exhibitors, lapsed sponsors, and attendees who bought once and never returned. The numbers are stark. According to industry research, the average trade show loses 25–35% of its exhibitors year over year, and only 44% of first-time exhibitors ever book a second edition. Rebooking a past exhibitor is roughly five times cheaper than acquiring a new one, yet most organizers have no structured outreach between show cycles. That's where win-back and reactivation calling providers come in. These services run done-for-you campaigns against your existing CRM or spreadsheet, using approved scripts to re-engage lapsed exhibitors, rescue expiring contracts, and follow up on old booth quotes. In this 2026 guide, we compare seven providers that help conference and trade show organizers turn dormant lists into rebooked booths and renewed sponsorships. We ranked them on list discipline, compliance handling, campaign structure, reporting transparency, and fit for event businesses. Whether you need a fully managed AI calling service or a human-led outreach team, you'll find a provider here that matches your show's cycle and budget.

#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; 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 (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. Owned and operated by AIQ Labs, the company is based in Halifax, Nova Scotia, with a U.S. operating base in Austin, Texas. For conference and trade show organizers, the service offers Win-Back & Reactivation Calling campaigns designed for contacts dormant 12–24 months, plus Database Reactivation Blitz campaigns that combine calls, texts, and emails over two to four weeks. The promise is simple: run more useful calls without building a bigger call center. You buy campaigns that the provider runs for you, with one clear goal per campaign quoted before launch. List discipline is a core selling point. Before any campaign launches, list source and consent records are reviewed. Bought lists without clear permission records are flagged and, in most cases, declined. As the company puts it: 'We tell you plainly if the list will not support the campaign, before you spend anything.' Compliance is treated as a feature. AI-generated voices are treated as artificial voices under the TCPA, with prior express consent required; state-specific quiet hours and day restrictions are honored; AI disclosure appears on every call; and keyword opt-outs (STOP and REVOKE) are respected immediately. Every campaign ends with a named outcome report containing disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed back into your CRM and scheduling tools. The company commits to no invented numbers: 'We report what actually happened.'

Best for: Conference and trade show organizers who want a fully managed, compliance-forward reactivation calling program run against their permissioned past-exhibitor or attendee lists, without hiring call center staff or managing software.

#2 CallMyCustomers — 9¢–21¢ per minute as volume grows; free list review before any fee.

CallMyCustomers offers done-for-you win-back campaigns specifically for conference and trade show organizers. According to their website, they run campaigns that reactivate lapsed exhibitors, follow up on old quotes, and rescue renewals, all approved by you and executed by their team. Their service is built around the reality that exhibitor churn silently drains revenue every cycle. They claim the average trade show loses 25–35% of exhibitors year over year, and only 44% of first-time exhibitors ever book a second edition. CallMyCustomers segments your list by recency (30 days / 6 months / 12+ months), pulls out old quotes that never became booth contracts, and identifies expiring sponsorships before they lapse. They offer a free list review and segmentation, so you know your rate, setup cost, and revenue potential before spending a dollar. The process includes script and offer approval, with every message pre-approved by you. Campaigns typically run two to four weeks end-to-end, timed to your show cycle. Replies route into your existing booking and rebook process. They claim to work from your CRM, spreadsheet, or POS list as-is, with no new software to learn. Pricing scales down from 9¢ to 21¢ per minute as volume grows. They state that real humans make calls, with automation handling scale only.

#3 Upcall — Contact for pricing, Upcall offers a free consultation but does not publish rates.

Upcall is a conversation-driven outbound calling platform that specializes in customer win-back campaigns, using real people to reconnect with past clients over the phone. According to their website, Upcall has been used by more than 4,000 companies and positions itself as a leading outbound calling solution for businesses that want to understand why customers went quiet, uncover new opportunities, and reintroduce products and services to inactive accounts. The workflow is straightforward: clients forward or upload their leads to Upcall, the team engages them at the right time with proven scripts, and results are delivered through a real-time dashboard with full visibility into campaign performance. For conference and trade show organizers, this means dormant exhibitors and sponsors can be called by trained human callers who can gauge interest, book follow-up meetings directly into a calendar, and surface insights about why they stopped participating. Upcall offers a free script consultation, automated follow-up calls, instant notifications when a campaign goal is reached, and appointment booking directly into the client's calendar. The human-caller model is a genuine strength for relationship-driven industries like events, where a warm voice and flexible conversation can matter more than scripted automation. Pricing is not published on the site, so exact costs require a consultation.

Best for: Conference and trade show organizers who prefer human callers for relationship-sensitive win-back conversations and want a managed campaign with calendar booking built in.

#4 TopCalls — $0.35 per minute, all-inclusive, per the company's website.

TopCalls offers AI voice agents purpose-built for customer reactivation and win-back calling. According to their website, the platform reaches dormant accounts with personalized conversations that reference each customer's history, last purchase, account details, and previous interactions, so contacts hear a relevant pitch rather than a generic one. The company states its agents can reach thousands of lapsed customers daily at a pace no human team could match. For conference and trade show organizers, the most relevant capabilities include churn-risk segmentation, where uploaded lists can be split by reason for leaving with a different script per segment, and offer delivery, where agents present targeted win-back incentives during the call and handle objections based on why the exhibitor stopped participating. Even refusals produce value: TopCalls collects the stated reason a contact left on every call, turning churn data into actionable insight for your event planning. TopCalls also supports reactivation tracking, measuring which contacts re-engaged or accepted offers, and re-onboarding support, where agents walk returning exhibitors through account updates and schedule check-ins. Pricing is published at $0.35 per minute all-inclusive, which the company says makes calling an entire dormant base economically viable. On compliance, TopCalls states that consent status is tracked per contact.

Best for: Conference and trade show organizers who want an AI-powered, high-volume reactivation tool with published per-minute pricing and the ability to segment by churn reason.

#5 MarketStar — Contact for pricing, MarketStar does not publish rates on their website.

MarketStar offers customer win-back and reactivation services as part of its broader customer success solutions. According to their website, they view lapsed customers as opportunities and specialize in reclaiming and reigniting connections through personalized strategies. Their approach begins with a comprehensive understanding of lapsed customers, using segmentation to categorize them by value, reasons for leaving, and potential for reactivation. They craft tailored reactivation campaigns that address the identified reasons for each customer's departure, highlighting new offerings, improvements, or incentives. Their multichannel outreach strategy includes email, direct mail, phone calls, and social media. They create customized reactivation offers or incentives at both the segment and individual levels. They also incorporate feedback from past interactions to make reactivation communication more relevant. Once customers express interest, they engage them with follow-up communications and additional information. Ongoing relationship management ensures that reactivated customers transition back into the customer base. They monitor reactivation rates, customer feedback, and revenue impact in real time. For conference and trade show organizers, MarketStar's services could be adapted to re-engage lapsed exhibitors and sponsors, though their focus is broader customer success across industries. Pricing is not published on their website.

Best for: Conference and trade show organizers who want a comprehensive, multichannel customer success partner with deep experience in reactivation across industries.

#6 Intelemark — Contact for pricing, Intelemark does not publish rates on their website.

Intelemark provides customer reactivation campaigns with a focus on telemarketing. According to their website, they deliver highly qualified B2B leads directly to sales teams. Their customer reactivation service targets people or accounts that previously purchased, engaged, or showed meaningful interest but have since become inactive. They emphasize that because the relationship already has history, the most useful outreach acknowledges context rather than treating the contact as new. Their guide explains how to segment dormant customers, diagnose likely reasons for inactivity, choose channels and offers, personalize outreach, and measure results. They offer telemarketing as a key strategy for customer reactivation, noting that it offers a human touch lacking in email and social media outreach, collects more insights from existing customers, and allows for customized messages. They state that their highly-skilled agents know how to communicate with inactive customers and gather valuable intelligence about why they were lost. For conference and trade show organizers, Intelemark's telemarketing-based reactivation could be used to re-engage lapsed exhibitors, though their focus is on B2B lead generation and telemarketing more broadly. Pricing is not published on their website.

Best for: Conference and trade show organizers who prefer a traditional telemarketing approach for B2B reactivation and want human agents to gather insights from lapsed exhibitors.

#7 Sono — Contact for pricing, Sono does not publish rates on their website.

Sono offers an AI phone assistant for lead reactivation. According to their blog, they help businesses reactivate old leads and past customers with a phone-led campaign. They explain that lead reactivation is the process of re-engaging old leads, stalled deals, and former customers who once showed interest but went quiet. They emphasize that it's the cheapest pipeline in your business because the relationship and a degree of trust already exist. Their guide covers which leads to revisit first, when to call versus email, what to say, and how an AI phone assistant like Sono can reactivate an entire database without burning out your team. They recommend starting with lapsed customers, then deals that stalled on timing, then high-intent enquiries that slipped through, and finally long-dormant, low-signal contacts. They provide a step-by-step lead reactivation campaign, including pulling and cleaning the list, segmenting by priority, giving each segment a reason to hear from you now, leading with the phone for high-priority tiers, setting a clear next step, and logging everything. They also offer a reactivation opener script. For conference and trade show organizers, Sono's AI phone assistant could be used to call lapsed exhibitors and past attendees. Pricing is not published on their website.

Best for: Conference and trade show organizers who want an AI phone assistant to run phone-led reactivation campaigns against their dormant lists, with guidance on segmentation and scripting.
