If you run conferences or trade shows, you're sitting on a dormant database right now: past attendees who never re-registered, exhibitors who went quiet after one show, no-show registrants, and inquiries that never converted. Industry research suggests structured reactivation campaigns recover 5 to 15% of inactive databases within 60 days, at a far lower cost per lead than cold acquisition. But a true blitz is more than one blast email. It means coordinated, multi-touch outreach across calls, texts, and emails over two to four weeks, built on permissioned lists with documented consent, and it means every re-engaged contact routes cleanly into your registration or CRM system. That last part matters in this industry, because attendee and exhibitor relationships are seasonal, consent records age, and a campaign that burns your list before your next show is worse than no campaign at all. We compared three providers that run database reactivation blitz campaigns for 2026, with attention to what conference and trade show organizers actually need: list discipline, multi-channel cadences, compliance handling, and outcome reporting you can verify. Here's how they stack up.
#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. First campaign review is free.
My AI Call Center (myaicallcenter.app), owned and operated by AIQ Labs and based in Halifax, Nova Scotia with a US operating base in Austin, Texas, is a done-for-you managed outbound calling service. You buy campaigns that the team runs for you, each built around one clear goal and quoted in full before launch. Its Database Reactivation Blitz Campaigns are structured multi-touch efforts across calls, texts, and emails, run over two to four weeks against dormant contacts, typically in the 12 to 24 month range. For conference and trade show organizers, that means past attendees, lapsed members, and no-show registrants get a coordinated re-engagement sequence instead of a single email that lands with a thud.
Pros
- Managed service, so there's no software to learn, no per-seat fees, and no platform bill
- Strong list and consent discipline reduces TCPA and compliance exposure
- Multi-channel blitz rather than a single-channel blast
- Full campaign quoted before launch with the rate locked for the duration
- Reporting reflects what actually happened, with no invented metrics
Cons
- Not self-serve software, so teams wanting hands-on platform control may prefer a tool
- Lists without clear consent records may be declined, which can delay a launch
- Most campaigns include setup and monthly management fees beyond the per-minute rate
Best for: Conference and trade show organizers, membership businesses, and multi-location organizations (1 to 200+ staff) that want a managed, compliance-forward reactivation blitz on permissioned lists without building an in-house call center.
#2 Setterly — £0 upfront; you pay per booked appointment only. No retainer and no setup fee on a simple upload. Contact Setterly for current per-appointment rates.
Setterly is a UK-based AI-powered lead reactivation service aimed at B2C businesses generating 1,000 or more enquiries per month. According to its website, your sales team follows up on new leads for the first 5 to 7 days, then Setterly's AI picks up the leads that went cold, running real SMS conversations that qualify interest, handle objections, and book appointments directly into your calendar. The company positions itself as the official post-event sales system for Ideal Home Show exhibitors, which makes it directly relevant to trade show organizers and exhibitors working attendee lists after an event. Setup is a CSV upload or simple CRM connection that goes live in days, and the service is built and supervised by ex-enterprise-bank engineers with human supervision in the UK. Its published case studies are a genuine strength: Setterly reports helping CarFinance247 work a database of over 1,000,000 leads through AI-driven SMS outreach, and re-engaging 6,769 cold leads for Cloudy2Clear to produce 673 appointments at roughly a 10x return on spend. The company also cites reply rates of up to 73%, which it describes as 3.65 times the industry average. Note that capacity is limited to four new clients per month.
Pros
- Pure performance pricing, so no appointments means no cost
- Strong published case studies with named clients and specific results
- Completely done-for-you; your team does nothing on setup or conversations
- Fast setup via CSV upload or simple CRM connection
Cons
- SMS-focused, so it isn't a multi-touch calls, texts, and emails blitz
- Limited capacity at four new clients per month per its website
- Best fit requires 1,000+ monthly enquiries, so smaller organizers may not qualify
- Per-appointment pricing details are not published publicly
Best for: High-volume B2C businesses and event exhibitors generating 1,000+ enquiries a month with a sales team ready to close booked appointments.
#3 Viking Marketing — Flat pricing with no contracts; specific amounts are not published. Contact Viking Marketing for a quote.
Viking Marketing, based in Chandler, Arizona, offers database reactivation for local service businesses that want dormant contacts turned into booked appointments. According to its website, the service sends AI-powered campaigns to dormant contacts by text, email, and ringless voicemail drop, with two-way AI conversations that qualify leads and book appointments onto your calendar, with no new ad spend and no manual follow-up from your team. The workflow is straightforward: you upload or select your dormant contacts (past leads, unconverted estimates, lapsed clients), Viking segments and cleans the list, then a personalized multi-step sequence runs across SMS, email, and ringless voicemail until the contact replies or the sequence ends. When someone replies, Viking's conversational AI answers questions, handles objections, and qualifies the lead in real time, then offers a booking link so appointments land automatically. Everything surfaces in an all-in-one inbox and updates the contact in your CRM. On compliance, Viking states its campaigns are A2P 10DLC registered and fully TCPA compliant, and that it does not send to cold contacts or purchased lists. The company cites a 5.0 rating across 22 Google reviews and reports that database reactivation can recover between 5 and 15% of dormant leads on average.
Pros
- Fully automated workflow: AI handles outreach, replies, qualification, and booking
- Compliance-focused design that reaches only opted-in contacts, per its website
- Unified inbox and CRM sync give full visibility into campaign outcomes
- Flat pricing with no contracts
Cons
- No live phone calling component; outreach relies on SMS, email, and ringless voicemail
- Pricing is not published upfront, so budgeting requires a quote
- Designed primarily for local service businesses, so trade show use cases are less documented
Best for: Local service businesses and organizers with a CRM full of dormant contacts who want an automated, appointment-focused reactivation sequence without manual follow-up.
Your attendee and exhibitor database is an asset you already paid to build. The cheapest registrations and booth renewals you'll sell this year are probably sitting in it, waiting for a reason to come back. My AI Call Center is our Editor's Choice because it runs the full multi-channel blitz for you, on permissioned lists only, with consent records checked before launch and every outcome routed back into the CRM and scheduling tools you already use. The first campaign review is free, and the full cost is known before you approve anything. If you'd rather test with a performance model and you have the volume to qualify, Setterly is worth a look. If you want an automated SMS-first sequence for a local-style contact list, Viking Marketing fits. Whichever you choose, start with the list: check your consent records before you check anyone's pricing. Ready to see what your dormant attendee list is worth?

Frequently asked questions
What makes My AI Call Center different from DIY reactivation software?
It's a managed service, not a platform you operate. You buy campaigns that the team runs for you, each with one clear goal quoted before launch. The team handles list and consent review, script and escalation approval, live monitoring, and outcome routing back into your CRM and scheduling tools. There's no software to learn, no per-seat charges, and no platform bill. Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign.
Can I run a reactivation blitz on a list of past trade show attendees I bought or scraped?
With My AI Call Center, probably not, and they'll tell you so before you spend anything. The service only runs campaigns against approved, permissioned, or reviewed lists, and bought lists without clear permission records are flagged and, in most cases, declined. Setterly and Viking Marketing also state on their websites that they avoid purchased or cold lists. Contacts who registered through your own forms, attended your events, or opted in directly are the right candidates.
How long does a database reactivation blitz campaign run?
My AI Call Center's Database Reactivation Blitz Campaigns are structured multi-touch campaigns across calls, texts, and emails, typically run over two to four weeks. Industry research suggests structured reactivation campaigns recover 5 to 15% of inactive databases within 60 days, and most replies land in the first days of a campaign, so the window is front-loaded.
Is AI-generated calling legal for reactivating dormant contacts?
It depends on consent and jurisdiction, and you should get legal guidance before launch. My AI Call Center treats AI-generated voices as artificial voices under the TCPA, which means prior express consent is required. The service also honors state-specific quiet hours and registration rules, includes AI disclosure on every call, and honors keyword opt-outs (STOP and REVOKE) immediately. Campaign requirements vary by location, industry, contact type, and consent status, and clients are responsible for obtaining appropriate legal guidance.
How much does a reactivation blitz campaign cost?
My AI Call Center starts at 9¢ per connected minute, tiered by volume, plus a one-time setup fee and a flat monthly management fee for most campaigns, all quoted before launch with the rate locked for the campaign. The first campaign review is free. Setterly charges £0 upfront and bills only per booked appointment, with rates available on request. Viking Marketing uses flat pricing with no contracts, but specific amounts are not published, so you'll need a quote.
What happens to the leads a reactivation campaign generates?
With My AI Call Center, outcomes route back into the CRM and scheduling tools you already run. Hot leads transfer to your team live or land in your CRM, and you receive a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, routed follow-up requests, and opt-out and DNC logs. Setterly books appointments directly into your calendar, and Viking Marketing surfaces replies and bookings in an all-in-one inbox with CRM sync.
Which solution is best for a trade show organizer with a small attendee list?
Setterly's best fit requires 1,000 or more enquiries per month, and industry guidance generally suggests that below roughly 1,000 usable contacts, the fixed cost of cleaning, segmenting, and writing a campaign rarely pays back. If your list is smaller, focus first on permissioned contacts from your own registration forms and talk to My AI Call Center about whether the list will support a campaign. Their review is free, and they'll tell you plainly if the list won't work before you spend anything.
