5 Top-Rated Event & Webinar Reminder Calls for Managed IT Services Provider (MSP)s

If you run an MSP, you already know the math on webinars. You spend weeks prepping a session on cyber insurance readiness or Microsoft 365 security, you get a room of registrants, and then roughly half of them don't show. Benchmarks from Univid's 2026 webinar statistics report put average live attendee engagement at about 49%, which means every registration list you build is quietly losing half its value between signup and showtime. Email reminders alone don't fix this. Registrants are drowning in IT pitches, security warnings, and cold outreach, so a confirmation email buried in an inbox is easy to ignore. A voice call is different. It gets answered, it confirms attendance in a live conversation, and it gives a busy business owner a moment of actual attention before your event. In 2026, MSPs have a real range of options here, from fully managed calling services that run campaigns for you to self-serve platforms your own team operates. This guide compares five of the top-rated event and webinar reminder call solutions for managed IT services providers, with attention to compliance, list quality, and how each one fits an MSP's lean staffing reality.

#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, all quoted before launch. The first campaign review is free.

My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service owned and operated by AIQ Labs, based in Halifax, Nova Scotia with an operating base in Austin, Texas. The pitch for MSPs 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, and each campaign is scoped around one clear goal, quoted in full before launch. For an MSP hosting a monthly webinar on ransomware readiness or a client training session on security awareness, the Event & Webinar Reminder Calls campaign supports same-day, day-before, or multi-touch reminder windows, so your registrants get a live, structured call that confirms whether they'll attend instead of another email they'll skim past. What sets My AI Call Center apart is list discipline, and that matters a lot for MSPs whose brand depends on trust. The service only calls approved, permissioned, or reviewed contact lists. List source and consent records are checked before any campaign launches, and bought lists without clear permission records are flagged and, in most cases, declined. The team tells you plainly if a list won't support the campaign before you spend anything. Every call includes AI disclosure, recipients can ask if the call is AI-assisted, request a human, or opt out with keywords like STOP and REVOKE, and state-specific quiet hours and calling windows are honored. AI voices are treated as artificial voices under the TCPA, with prior express consent required. The reporting is where MSPs will see the practical payoff. You get a named outcome report with disposition codes (confirmed, no answer, opted out), per-call notes, and follow-up requests routed back into the CRM and scheduling tools you already run, with hot responses transferring to your team live. A registrant who says "actually, I'd rather talk to someone about an assessment" becomes a routed follow-up, not a lost note. The company reports what actually happened and never invents client logos, testimonials, metrics, or ratings. Calling starts at 9¢ per connected minute, tiered by volume, with the rate locked for the campaign. Most campaigns add a one-time setup and a flat monthly management fee, both quoted before launch. No per-seat charges, no platform bill, and no minimums you didn't choose. The first campaign review is free.

Best for: MSPs that want a fully managed, compliance-forward reminder calling service to confirm attendance at webinars, client training sessions, and security awareness events without adding call center staff or new software.

#2 Sigma Voice — Contact for pricing

Sigma Voice offers automated reminder calls that MSPs can use to boost attendance at webinars, lunch-and-learns, and client education events. According to their website, the platform lets you upload a contact list, create a message using a professional recording or text-to-speech, and schedule calls to go out automatically before your event. Messages can be personalized with details like the recipient's name, the event date, the start time, and the join link or venue, which matters when you're reminding a mixed room of clients and prospects about a session with specific logistics. The platform also supports interactive voice response, which is useful for MSPs that want more than a one-way blast. According to their website, recipients can press a key to confirm attendance, request a callback, or transfer to a live representative at your office. That confirmation mechanic is the piece that turns a reminder into a measurable outcome, since your team can see who confirmed and who needs a second touch. Sigma Voice also emphasizes that voice calls are harder to overlook than email alone, which lines up with what most MSPs see in their own webinar show-up rates. For reporting, the platform provides campaign reports showing completed calls, voicemail deliveries, and recipient responses. Contacts can be imported from a list, pulled from a CRM, or added through an API. Sigma Voice does not publicly disclose pricing in the materials reviewed, so MSPs should contact the vendor directly for current costs.

Best for: MSPs that want a self-serve automated voice reminder platform with IVR confirmations for webinars, client events, and staff notifications.

#3 DialMyCalls — Contact for pricing; free trial available per their website

DialMyCalls is a self-serve automated messaging platform that sends voice calls, text messages, and emails for appointment and event reminders. According to their website, the platform is used by more than 40,000 organizations across the US and Canada and has delivered over a billion messages, which gives MSPs some confidence it's a proven tool rather than an experiment. For an MSP running monthly webinars or client training sessions, DialMyCalls offers a straightforward way to remind registered attendees without building custom telephony infrastructure or adding headcount. The platform supports one-time and recurring reminder campaigns with configurable calling windows, so calls land within defined hours instead of annoying people at dinner. According to industry reviews, DialMyCalls can attach interactive voice prompts that capture confirmation or cancellation during the same reminder call, which cuts down the manual follow-up your team would otherwise do. Campaign-level delivery and outcome reporting gives your operations people a practical per-contact view of what happened, and webhook integration can send call outcome events so workflows trigger CRM updates automatically. That last point matters for MSPs living in ConnectWise or HubSpot. The tradeoff is that DialMyCalls is self-serve. Your team owns the contact lists, the message recordings, and the opt-out handling. Reviewers note that answer and voicemail detection tuning can take some iterations, and advanced branching flows depend on careful script design. A free trial is available without a credit card, according to their website, so you can test it against a real webinar before committing.

Best for: MSPs that want an easy-to-use, self-serve reminder system their own team can run for webinars, client events, and staff communications.

#4 Call Loop — Subscription plus per-drop ringless voicemail fees; contact Call Loop for a full quote

Call Loop is a multi-channel automated messaging platform that, according to its reviewed materials, orchestrates communications across SMS, voice calls, and ringless voicemail within automated drip campaigns. For MSPs running webinars, this multi-channel approach is genuinely useful because it lets you build layered reminder sequences: a text the day before the event, then a final automated voice call shortly before it starts, all managed from a single dashboard. The vendor's own guidance highlights event organizers using this kind of sequencing to lift show-up rates. According to their website, Call Loop supports personalized scheduled SMS, drip campaigns, voice broadcasts, and analytics, along with number validation, link tracking, and double opt-in. For MSPs with an existing CRM, Call Loop integrates with ActiveCampaign, HubSpot, and Keap, plus Zapier access to roughly 4,000 apps, which means confirmation replies and opt-outs can flow back into your existing systems without manual copy-paste. The platform also states HIPAA support for regulated organizations, which is worth noting for MSPs serving healthcare clients. Pricing is subscription-based with per-drop ringless voicemail fees, described as a pay-as-you-grow model, though full public pricing details are limited. MSPs should contact Call Loop for a complete quote based on their list size and campaign cadence. As a self-serve tool, your team owns script design, list hygiene, and compliance handling, so it works best when you have someone internally who can own the campaign.

Best for: MSPs that want multi-channel reminder sequences (text plus voice) for webinars and already have a CRM to sync with.

#5 CallMultiplier — Contact for pricing

CallMultiplier is a self-serve automated voice calling service for reminders, notifications, and alerts. According to independent 2026 reviews, it ranks among the easiest-to-use reminder call platforms, with scheduled campaigns that pull from uploaded contact lists and apply per-campaign dialing rules. For MSPs, that ease of use is the main draw: if your team is small and nobody has time to learn a complex telephony stack, a platform you can set up in an afternoon for a webinar reminder batch has real value. The platform's standout strength, according to review data, is per-campaign call outcome reporting with disposition-level results tied to each scheduled reminder attempt. That gives your coordinators clear visibility into who was reached, who confirmed, and who needs a follow-up touch before the webinar goes live. Compliance-oriented mechanics are built into the dialing flows, including opt-out handling and do-not-contact management, which matters when you're calling a mixed list of existing clients and registered prospects. CallMultiplier is best suited to structured, scheduled reminder batches rather than complex conversational flows. It's a solid fit for MSPs that want a proven, no-frills voice reminder tool their own team can operate. Pricing is not publicly disclosed in the reviewed materials, so contact the vendor for current rates.

Best for: MSPs that want a simple, easy-to-use self-serve voice reminder tool for scheduled webinar and event reminder batches.

Every MSP that runs webinars eventually hits the same wall: registrations are easy to count, but show-up rates decide whether the event actually feeds your pipeline. With average live attendance hovering around 49% in 2026 benchmarks, reminder calls are one of the few levers that reliably move that number, because a live voice conversation gets attention in a way a fifth reminder email never will. The right choice depends on how your team is built. If you have marketing staff with time to own campaigns, self-serve platforms like Sigma Voice, DialMyCalls, Call Loop, or CallMultiplier give you the tools to run reminder batches yourself. If your team is stretched thin and you'd rather buy outcomes than software, a managed service takes the whole job off your plate. My AI Call Center is our Editor's Choice because it handles everything end to end: consent-checked lists, approved scripts, compliant calling windows, and outcome reports with disposition codes routed straight into your CRM, all from 9¢ per connected minute with the rate locked before launch. If you're planning your next client webinar or security training event, start with a free campaign review at myaicallcenter.app/campaigns and find out what a structured reminder campaign would actually cost before you spend anything.
