Top 7 Event & Webinar Reminder Calls for Corporate Event Planning Companies

If you run corporate events for a living, you already know the math. Registration counts don't pay the bills; people in seats do. Live show-up rates for webinars ran roughly 38% to 48% in 2026 benchmarks, and even the best email sequences get buried. A short, well-timed phone call still cuts through better than almost anything else, because it gives a registrant a moment to confirm, reschedule, or ask a question on the spot. The hard part is that most event planning teams don't have spare staff to dial hundreds of registrants, and self-serve dialing tools can create compliance headaches if your lists and consent records aren't airtight. We put together this 2026 list of seven event and webinar reminder call options for corporate event planning companies. Our top pick, My AI Call Center, is a fully managed calling service built around strict list discipline and transparent reporting. The rest range from broadcast reminder platforms to AI voice agents and human telemarketing teams, so you can match the tool to how your team actually works.

#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) is a done-for-you managed outbound calling service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. It's owned and operated by AIQ Labs, based in Halifax, Nova Scotia, with an operating base in Austin, Texas. The promise is simple: run more useful calls without building a bigger call center. This is a managed service, not software. You buy campaigns that the team runs for you end to end, from campaign review and consent verification through script approval, launch, monitoring, and outcome routing back into the CRM and scheduling tools you already use. For corporate event planning companies, the Event & Webinar Reminder Calls campaign supports same-day, day-before, or multi-touch reminder windows. Each campaign is scoped around one clear goal, like getting more registrants to confirm for a client webinar or a product launch event, and quoted in full before it launches. What sets the service apart is list discipline. List source and consent records are checked before any campaign starts, and bought lists without clear permission records are flagged and, in most cases, declined. The team tells you plainly if your list won't support the campaign before you spend anything. Compliance is built in. AI-generated voices are treated as artificial voices under the TCPA, with prior express consent required and AI disclosure on every call. Recipients can ask if the call is AI-assisted, request a human, or opt out with keywords like STOP and REVOKE, and those opt-outs are logged and honored immediately. You get a named outcome report with disposition codes (confirmed, rescheduled, cancelled, no answer), per-call notes, and follow-up requests routed to your team, with hot responses transferred live or delivered to your CRM. The company reports what actually happened and never invents metrics or testimonials.

Best for: Corporate event planning companies and multi-location organizations (typically 1-200+ staff) that want a managed, compliance-forward reminder calling service without hiring internal call center staff

#2 DialMyCalls — A few cents per call or text; free trial available. Contact DialMyCalls for detailed plan pricing.

DialMyCalls is a mass notification platform that lets organizations send automated event reminders via phone call or SMS broadcast to hundreds or thousands of contacts at once. According to their website, the service is built around a simple insight: most no-shows happen because people forget, and a quick reminder call or text the day before an event can meaningfully improve turnout. The platform reports over 40,000 customers across the US and Canada and more than a billion messages sent, with a 4.8 out of 5 rating from more than 1,500 reviews across Capterra, G2, and other platforms. For event planning companies, the useful pieces are message personalization and telephone polling. Users can record a reminder in their own voice so the message sounds friendly and on-brand, and recipients can press a key to RSVP whether they'll attend, which helps with headcounts for catering, seating, and staffing. According to their website, a free trial is available with no credit card required, and messages cost a few cents per call or text. The tradeoff is that it's self-serve: your team manages lists, scripts, and compliance internally, and there's no managed campaign service or deep CRM outcome routing.

Best for: Event planning teams with an opted-in contact list that want a self-serve broadcast tool for reminder calls and RSVPs

#3 Retell AI — Contact for pricing

Retell AI offers an Event & Webinar Reminder template for building an outbound AI voice agent. According to their template page, the agent calls registered attendees ahead of an event, confirms they still plan to attend, and recaps the date, time, timezone, and how the access link will be delivered. For attendees who can't make it, the agent offers to move their registration to the next available session or process a cancellation, both wired to backend functions with confirmation messaging on success or a fallback to email or web cancellation if the backend step fails. The template also includes a scoped FAQ knowledge base covering event timing, how to join, whether sessions are recorded, and switching sessions, plus an out-of-scope handoff that transfers the call to a team member with callback capture if the team is unavailable. For event planning companies with engineering resources, this is a flexible way to build conversational reminder calls that feel closer to a live agent than a recorded broadcast. The catch is that it's a build-it-yourself platform: you're responsible for wiring backend functions, managing consent and compliance, and maintaining the agent over time.

Best for: Technical teams that want to build and customize their own AI reminder calling agent

#4 Call Loop — Free trial available; contact Call Loop for full pricing details.

Call Loop is a multi-channel automated messaging platform that combines SMS, voice calls, and ringless voicemail in a single workflow. According to their website, Call Loop's strength is orchestration: a contact might receive an SMS reminder 24 hours before an event, followed by a ringless voicemail drop two hours before, all managed from one dashboard. That layered approach fits corporate events where a single reminder often isn't enough to move a busy registrant. Call Loop also highlights a webinar use case on its site: send an initial email confirmation, a reminder text the day before, and a final automated call one hour before the event starts. The platform offers a HIPAA-compliant option for handling sensitive information and connects natively with tools like HubSpot and Keap, according to their website, which matters for event teams that want reminder outcomes to sync with their marketing stack. A free trial is available, with full pricing available on request. Like the other self-serve options here, your team owns the lists, sequencing, and compliance handling.

Best for: Event teams that want layered, multi-channel reminder sequences they control in-house

#5 VoiceShot — Contact for pricing

VoiceShot provides automated call reminder software and voice broadcasting services, and according to their website, the company has been delivering voice communication services for 21 years. The platform handles alerts, voicemails, notifications, reminders, and surveys, and users can run interactive calls directly from a web browser. For event planning companies, the practical appeal is the feature set around reminder delivery: call scheduling for any day or time, calendar integration with tools like Google Calendar and Outlook, and conditional call branching so a key press from a recipient can route the call, for example transferring to a live agent or playing a different message. VoiceShot's blog also emphasizes reliability and reporting. Users can edit messages on the fly (start, stop, pause, speed up, slow down), view real-time results including success and failure rates, and identify who confirmed, canceled, or rescheduled. Recording options include recording by phone, computer mic, or uploading pre-recorded files, plus text-to-speech for customization. It's another self-serve tool, so list consent and regulatory handling stay with your team, but for planners who want granular control over call flows, it's a mature option.

Best for: Event teams that want fine-grained control over call flows, branching, and reporting

#6 ReminderCall.com — Contact for pricing

ReminderCall.com, operated by Reminder Services, Inc., is a Silicon Valley-based company founded in 1998 that specializes in automated appointment reminder calls, text messages, and emails. According to company profile data, their services integrate with various software systems, and their focus areas include automated appointment reminders, communication software, HIPAA compliance, integration services, and white label partnerships. That last one matters for event planning companies: a white label option means an agency can run reminder calls for client events under its own brand. For corporate event work, ReminderCall.com covers the core reminder job across three channels: voice calls, texts, and emails. The company's long operating history (since 1998) suggests a stable, focused product rather than a feature-of-the-month platform. The tradeoffs are typical of a small, specialized provider: a two-employee operation means less breadth than larger platforms, and you'll want to confirm current integration options and pricing directly, since detailed plan pricing isn't published in the research we reviewed.

Best for: Agencies and event firms that want a long-established reminder service with white label options

#7 Kentwood Partners — Contact for pricing

Kentwood Partners provides event telemarketing services designed to boost last-minute attendance for business conferences, seminars, associations, and tradeshows. According to their website, the company specializes in personalized phone calls to prospective attendees as a follow-up to email campaigns, combining warm telephone outreach with personal emails and text messaging to increase registration and turnout. Their approach focuses on expressing the event's value proposition, outlining the agenda, and creating urgency to drive registrations, especially when an event is approaching and attendance is below target. Each phone call is supplemented by a personal email containing requested information or registration links, and the company emphasizes professional communication, active listening, and detailed follow-up. For corporate event planning companies running high-value conferences or client events, this is the human-powered alternative to automated systems: trained telemarketers can answer questions, handle objections, and re-engage hesitant registrants in ways a recorded broadcast can't. The costs are equally clear. Human agents mean a higher cost per contact than automated systems, less scalability for very large lists, and dependence on agent availability and training quality.

Best for: Corporate event planners running high-value conferences who want human agents handling reminder and registration outreach

Choosing the right event and webinar reminder call provider comes down to how your team works and how much compliance risk you're willing to carry in-house. If you want calls made for you, with consent records verified before launch, scripts approved by your team, and outcomes routed straight into your CRM, My AI Call Center is the strongest fit, and calling starts at 9¢ per connected minute with the full campaign cost quoted before anything launches. Your first campaign review is free, so there's no reason not to scope one out. If you'd rather run things yourself, DialMyCalls and Call Loop offer solid self-serve broadcast and multi-channel options, Retell AI suits technical teams building custom agents, and VoiceShot and ReminderCall.com cover the reminder basics with mature tooling. For high-stakes conferences where a human voice matters, Kentwood Partners is worth a call. Whichever direction you take, remember that the provider only matters if the list behind it is clean, permissioned, and properly documented. Start with the list, then pick the tool.
