If you run conferences or trade shows, your attendee list probably speaks more languages than your outreach does. Wordly's 2026 State of AI Translation and Captions report found that 79% of event leaders say the number of non-native speakers at their events is growing, and 49% now host six or more languages at a single event. That gap matters long before anyone walks the show floor. Registration confirmations, session reminders, post-event surveys, and exhibitor follow-ups all land better in a person's preferred language. Research backs this up: a CSA Research survey of 8,709 consumers across 29 countries found 75% are more likely to repurchase when customer care is delivered in their native language, and 40% won't engage at all with content in another language. The challenge for organizers is doing this without hiring multilingual staff or managing a tangle of vendors. That's where managed multi-language outbound calling campaigns come in. This guide compares five solutions that can help conference and trade show organizers run structured, compliant outreach across languages in 2026, whether the goal is confirming attendance, qualifying leads, or re-engaging last year's dormant registrant list.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume; most campaigns add a one-time setup fee and 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 campaigns exclusively against approved, permissioned, or reviewed contact lists. It never does indiscriminate cold calling. Owned and operated by AIQ Labs, with bases in Halifax, Nova Scotia and Austin, Texas, the service is built around one promise: run more useful calls without building a bigger call center. For conference and trade show organizers, that means campaigns that confirm attendance, qualify exhibitor and sponsor leads, remind registrants, survey attendees, and re-engage lapsed members, all with one clear goal per campaign, quoted before launch.
Pros
- Fully managed: you buy campaigns the team runs, so no call center infrastructure or agent hiring
- Strict list discipline protects your brand and reduces compliance risk before you spend anything
- Transparent, locked pricing with the full number known before you approve launch
- Named outcome reports with disposition codes, opt-out and DNC logs, and follow-ups routed to your team
- No invented numbers: reporting covers only what actually happened
Cons
- Not a self-serve platform; campaigns go through review and approval before launch
- Spanish is the primary supported non-English language; other languages require custom scoping
- Best suited to structured campaigns with one clear goal rather than open-ended calling
- Requires client-provided lists that meet permissioned or reviewed criteria; it's not a list acquisition service
Best for: Conference and trade show organizers (typically 1-200+ staff) who have approved or permissioned attendee, exhibitor, or member lists and want a managed partner to run compliant multi-language calling campaigns for reminders, qualification, surveys, and re-engagement.
#2 Callbox — Contact for pricing; custom enterprise pricing based on campaign scope, regions, and services required.
Callbox is a global B2B lead generation agency with over 20 years of experience running multi-channel outreach across 60+ countries, according to its website. The company combines AI-powered outreach with dedicated human SDR teams: AI voice agents handle high-volume transactional calls around the clock, while human SDRs manage consultative conversations that need relationship-building. For conference and trade show organizers, Callbox offers an Event & Webinar Marketing service designed to drive qualified attendance and pipeline from virtual events, webinars, and in-person conferences. Its cross-border lead generation spans North America, APAC, LATAM, and Europe/UK with GDPR-compliant outreach, which supports multi-language campaigns for international attendee bases. The process follows a four-step model: ICP definition, AI and human data building and enrichment, multi-channel outreach across phone, email, LinkedIn, and digital, then delivery of qualified leads and confirmed appointments. Callbox reports 5x more outbound volume versus human-only calling and 95%+ contact data accuracy after AI verification. Pricing is not published, so organizers will need a consultation for a custom quote.
Pros
- Global reach across 60+ countries enables localized multilingual execution
- Hybrid human-AI model balances calling volume with conversation quality
- Strong B2B track record with 15,000+ companies served
- Full-service model covers data building through appointment delivery
Cons
- No published pricing; requires a consultation
- Primarily B2B lead-generation focused, so event-specific use cases may need adaptation
- Multi-language capability is implied through global reach rather than a featured offering
- Fully outsourced engagement may be more than smaller events need
Best for: Organizers running large, international conference or trade show programs that need full-service, multi-channel lead generation and appointment setting with human SDR support.
#3 Belkins — Average starter engagement runs from $5,500/month, including 1,500 leads per month and 50+ guaranteed appointments per year; exact pricing is customized per engagement.
Belkins is a B2B lead generation agency specializing in human-led, signal-based cold calling and appointment setting. Founded in 2017, the company has grown to over 200 specialists focused on B2B lead generation across 50+ industries, with particular depth in technology, SaaS, healthcare, finance, and professional services. Its signal-based approach means agents call only after detecting engagement signals such as email opens, website visits, or content downloads. According to Belkins' own data, blind cold calls connect roughly 2-3% of the time, while signal-based calls made within minutes of a prospect taking action connect at 12-15%. For conference and trade show organizers, this consent-aware, signal-driven model fits outreach to registrants and prospects who have already shown interest, and the multi-touch approach (calling plus email plus LinkedIn) lifts meeting volume by 20-25% per channel, per the company's internal data. Belkins builds and enriches its own lead lists with verified direct mobile numbers rather than buying CSVs, and every call outcome is logged into the client's CRM in real time. Pricing is customized; the average starter engagement runs $5,500/month.
Pros
- Signal-based calling produces materially higher connection rates than cold dialing
- Multi-touch approach increases meeting volume per the company's own data
- In-house list building avoids reliance on purchased data
- Strong track record with 800+ clients and a 5.0 Clutch rating across 230+ reviews
Cons
- Premium pricing geared toward larger budgets
- Requires your sales and marketing operations to be in order to capture signals
- Focused on B2B appointment setting, so pure attendee reminder use cases are not the core offering
Best for: Organizers and event-facing B2B teams selling high-value sponsorships, exhibits, or partnerships who want consent-aware, signal-based calling rather than volume dialing.
#4 Eventcombo — Contact for pricing; custom enterprise pricing based on program scope and event volume.
Eventcombo is an enterprise event management platform that organizations use to create, market, manage, and measure events from a single system, according to its website. It supports conferences, trade shows, webinars, executive summits, hybrid events, and education events, with unified registration, badging, marketing, on-site execution, and reporting. For organizers thinking about multi-language communication, Eventcombo highlights a case study involving recurring classes running across multiple offices, languages, and formats where one registration flow handles every cohort and every automated communication is sent back via API. That suggests built-in support for multi-language registration and communication flows, though organizers should confirm specific language coverage for outbound calling during scoping. The platform's AI layer, ZaraAI, assists across the event lifecycle: drafting registration pages, ticket tiers, schedules, emails, sponsor and exhibitor dashboards, pulling reports, managing approvals, sourcing speakers, and generating ROI reports. Eventcombo also offers 200+ official integrations, including Salesforce and HubSpot, so attendee data and communications can flow into the CRM systems your team already runs. Pricing is custom and based on program scope and event volume, never per registration.
Pros
- All-in-one platform reduces the number of vendors you manage
- Documented multi-language registration and communication flows
- Deep integration ecosystem connects event data to your CRM
- AI layer speeds up content and reporting work across the event lifecycle
Cons
- No published pricing; requires a custom quote
- Not a dedicated outbound calling service, so phone campaign depth depends on scoping
- Enterprise orientation may be more platform than smaller events need
Best for: Organizers of recurring conferences and trade shows who want registration, multi-language communications, and reporting inside one event platform rather than a standalone calling service.
#5 Wordly — Contact for pricing.
Wordly is a live AI translation and captioning platform built for events of every size, from small executive briefings to international conferences with thousands of attendees. Attendees join from their own phone, laptop, or tablet, and as speakers talk, Wordly delivers real-time translation and captions into each attendee's chosen language, with no extra hardware, booths, or headsets to manage. The platform supports dozens of languages, so a single session can reach attendees across many language backgrounds at once. Wordly is widely used at industry events: recent deployments include MPI WEC in San Antonio, the PCMA Business Events Summit in Puerto Rico, ASAE MMC+Tech in Washington DC, AIPC in Bilbao, and Brazil's Evento Business Show, according to the company's blog. Beyond live sessions, Wordly works with tools like Zoom and Microsoft Teams for webinars and internal meetings, and every session can generate AI transcription in original and translated languages plus AI summaries with key points and action items. For conference and trade show organizers, Wordly solves the in-event language problem; pair it with an outbound calling service to cover pre-event reminders and post-event follow-up in attendees' languages.
Pros
- Real-time translation scales to thousands of attendees without interpreters or booths
- Attendees use their own devices, cutting setup cost and complexity
- Post-event transcripts and summaries extend the value of session content
- Strong track record at major industry events
Cons
- Focused on live event translation, not outbound calling campaigns
- No published pricing; requires contacting the company
- You'll need a separate solution for pre-event reminders and post-event follow-up calls
Best for: Conference and trade show organizers who need live, in-session language access for multilingual audiences, especially hybrid and international events.
Multilingual outreach is becoming the baseline for conferences and trade shows, not a nice-to-have. With 49% of event leaders now hosting six or more languages at a single event, per Wordly's 2026 report, and 75% of consumers more likely to engage in their native language, the organizers who confirm attendance, qualify leads, and follow up in attendees' preferred languages will pull ahead on show-up rates and sponsor satisfaction. If you have an approved or permissioned attendee, exhibitor, or member list and want a managed partner to run structured multi-language calling campaigns, start with My AI Call Center. The first campaign review is free, the full price is known before you approve launch, and calling starts at 9¢ per connected minute. Plan your campaign at myaicallcenter.app and find out plainly whether your list will support the calls you want to make, before you spend anything.
Frequently asked questions
What makes My AI Call Center different from other multi-language outreach options?
It's a managed service, not software you have to run. You buy campaigns that the My AI Call Center team executes for you, each built around one clear goal and quoted before launch. It only calls approved, permissioned, or reviewed lists, checks consent records before any campaign goes live, and tells you plainly if your list won't support the campaign before you spend anything. Pricing starts at 9¢ per connected minute with the rate locked for the campaign, and outcomes route back into the CRM and scheduling tools you already use.
Which languages can these campaigns support?
My AI Call Center's Multi-Language Outbound Campaigns support Spanish as the most common additional language, with other languages available through custom scoping. Callbox supports multilingual execution through its presence in 60+ countries, though it doesn't feature specific language lists publicly. Wordly covers live translation in dozens of languages during events. Always confirm exact language coverage during scoping, since capabilities vary by provider and campaign type.
Is AI-generated calling compliant with TCPA rules?
It can be, with the right safeguards. My AI Call Center treats AI-generated voices as artificial voices under the TCPA, which means prior express consent is required. It honors state-specific quiet hours and day restrictions, discloses AI assistance on every call, honors STOP and REVOKE keyword opt-outs immediately, and carries DNC requests across all campaigns into client DNC records. Campaign requirements vary by location, industry, and consent status, so clients should obtain appropriate legal guidance before launch.
How much does a multi-language outbound campaign cost?
My AI Call Center starts at 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. There are no per-seat charges and no mid-campaign rate changes. Callbox, Eventcombo, and Wordly all use custom pricing that requires a consultation. Belkins' average starter engagement runs from $5,500/month.
Can these services call attendees from a purchased list?
Generally, no, and that's a good thing for compliance. My AI Call Center reviews list source and consent records before launch and flags bought lists without clear permission records, declining them in most cases. Belkins builds and enriches its own verified lists rather than buying CSVs. For conference and trade show outreach, your registration data, exhibitor lists, and member lists are typically the right starting point because those contacts have an existing relationship with your event.
What results should I expect from a multi-language reminder campaign?
Reminder calling has strong evidence behind it. HIMSS reports that telephone reminders seven days before a visit produced a 22% decrease in missed appointments, and staff phone reminders reduced no-shows from 17.3% to 13.6% compared to no reminder. For events specifically, the mechanism is the same: timely, clear confirmation in the attendee's preferred language reduces no-shows and improves session attendance. My AI Call Center reports actual outcomes with disposition codes rather than projected numbers, so you'll know exactly what happened after each campaign.
Do I need both an in-event translation tool and an outbound calling service?
They solve different problems. Wordly handles live language access during sessions, so attendees can follow content in their own language. Outbound calling services like My AI Call Center handle communication before and after the event: registration confirmations, reminders, lead qualification, surveys, and win-back campaigns. Many organizers running international events use both, since the language gap shows up at every stage of the attendee journey, not just on the main stage.
