If you run webinars for a SaaS company, you already know the math is brutal. Industry data puts average live attendance somewhere between 40 and 50 percent of registrants, which means for every 100 people who sign up, fewer than 50 show up. Cloud Present's framework for top SaaS companies notes that leading teams push past 60 percent by working every touchpoint, and one of the touchpoints email consistently misses is the phone. Reminder calls cut through in a way a fourth email can't: a short, friendly call one or two days before the session confirms attendance, recaps the date and time, and gives the registrant a chance to reschedule instead of silently no-showing. Whether you want a managed service that runs the whole campaign for you, or a platform your team builds on, here are four options worth a look in 2026.
#1 My AI Call Center — 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. The first campaign review is free.
My AI Call Center is a done-for-you managed outbound calling service owned by AIQ Labs, based in Halifax, Nova Scotia with an operating base in Austin, Texas. The key thing to understand is that it's a managed service, not software: you buy campaigns that they run for you, each scoped around one clear goal and quoted before launch. For SaaS companies running webinars and product events, their Event & Webinar Reminder Calls campaign is exactly what it sounds like. AI-powered calls go out to your registered attendee list in approved windows, with same-day, day-before, or multi-touch timing depending on what you need. Because it's structured, each call confirms attendance, recaps the logistics, and routes the outcome back to you. What sets it apart for SaaS teams is list discipline and reporting honesty. They only run campaigns against approved, permissioned, or reviewed contact lists, and they check list source and consent records before anything launches. Bought lists without clear permission records get flagged, and in most cases declined. They'll tell you plainly if the list won't support the campaign before you spend anything. On the back end, you get a named outcome report with disposition codes (confirmed, qualified, renewed, opted out, no answer), per-call notes, and follow-up requests routed back into the CRM and scheduling tools you already run. Hot leads can transfer to your team live or land in your CRM. Their stated rule is no invented numbers: they report what actually happened, and opt-outs are logged and honored immediately. Compliance is treated seriously, which matters for any SaaS company calling prospects and customers in the US. AI-generated voices are treated as artificial voices under the TCPA, prior express consent is required, state-specific quiet hours and registration rules are honored, and AI disclosure happens on every call. Recipients can ask if the call is AI-assisted, request a human, or opt out. Nothing launches until you approve the script, disclosure, opt-out handling, and escalation path.
Pros
- Done-for-you: you buy campaigns, not seats or software
- Full cost known before launch, with no per-seat charges or platform bill
- Consent and list review happens upfront, so you don't burn budget on a list that won't work
- Honest reporting with disposition codes and opt-out logs
- Outcomes route directly into your existing CRM and scheduling tools
Cons
- Managed service, so it's not for teams that want to build and tune their own call agents
- Strict list standards mean lists without clear permission records will usually be declined
- Setup and management fees are quoted per campaign rather than published flat rates
Best for: SaaS companies and multi-location organizations (typically 1-200+ staff) that want reminder calls handled end-to-end without building an in-house call operation.
#2 Retell AI (Event / Webinar Reminder Template) — Contact for pricing
Retell AI offers an Event / Webinar Reminder template in its agent library, and according to their template page it's an outbound reminder agent built specifically for webinars, virtual events, and recurring sessions. 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. That's a tight match for the SaaS webinar use case, and the template was last updated in August 2026. Where it gets interesting is the backend wiring. According to their website, attendees who can't make it can be moved to the next available session or have their registration cancelled outright, both wired to backend functions with confirmation messaging on success or a clean fallback to email or web cancellation on failure. 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 to a team member with callback capture if nobody's available. If your SaaS team has engineering resources and wants to own the call flow, this is a credible DIY path.
Pros
- Purpose-built for the exact webinar reminder use case
- Handles rescheduling and cancellations, not just one-way reminders
- Scoped FAQ and human handoff give registrants a path to real answers
- Template gives you a working starting point rather than a blank slate
Cons
- It's a template on a platform, so you assemble and maintain the agent yourself
- Pricing isn't published on the template page
- You own the compliance, consent, and list-quality decisions
Best for: SaaS teams with technical resources that want to build and customize their own AI reminder call agent from a proven template.
#3 Call Loop — Contact for pricing. According to their site, pricing combines a subscription with per-drop ringless voicemail fees on a pay-as-you-grow model.
Call Loop is a multi-channel reminder platform that covers SMS, MMS, voice broadcasts, and ringless voicemail. According to their comparison guide, it's positioned for businesses that already have scheduling software but need a stronger reminder and outreach layer on top, which is a common situation for SaaS companies that already run webinar registration through a CRM or marketing automation tool. Instead of replacing your stack, it adds personalized scheduled messages and drip campaigns. Their voice broadcast capability is what earns it a spot on this list. According to their website, Call Loop supports voice broadcasts alongside SMS, with number validation, link tracking, and double opt-in. They also list HIPAA support and integrations with ActiveCampaign, HubSpot, and Keap, plus Zapier access to roughly 4,000 apps, so a webinar reminder sequence triggered off a registration event is realistic to set up. Their guide also cites real-world results elsewhere in the reminder space, including an El Rio Health case study reporting a 32 percent drop in missed appointments after automated reminders. It's a self-serve tool rather than a managed campaign, so your team builds and monitors the sequences.
Pros
- Multi-channel: SMS, voice, and ringless voicemail from one platform
- Strong integration coverage, including HubSpot and Zapier
- HIPAA support for healthcare-adjacent workflows
- Works on top of existing scheduling software rather than replacing it
Cons
- Self-serve, so your team builds and maintains the campaigns
- Voice broadcasts are one-way; it's not a conversational reminder agent
- Costs combine a subscription with per-message fees, which needs watching at scale
Best for: SaaS teams that already have a CRM or scheduling stack and want to add SMS and voice reminder campaigns themselves.
#4 ReminderCall — Usage-based reminder credits with volume discounts, and free trial credits, according to research data. Contact ReminderCall for current rates.
ReminderCall is a dedicated reminder service built around automated voice calls and SMS. According to the Call Loop comparison guide, it offers automated voice calls and SMS with long-text support, dedicated numbers, and live tech support, and it's aimed at healthcare and compliance-focused organizations. That voice-first orientation is why it makes this list: for a SaaS company whose registrants don't reliably read email, an automated phone reminder is the channel that gets noticed. According to the same research, ReminderCall is HIPAA-capable with a BAA available, and it uses usage-based reminder credits with volume discounts and free trial credits. It's a reminder engine rather than a conversational AI agent, so you won't get the reschedule-and-FAQ behavior of a template like Retell's, but for straightforward 'your webinar is tomorrow at 2pm' calls at scale, it's a simple, proven tool. The live tech support is worth noting for teams without a dedicated ops person to babysit reminder infrastructure.
Pros
- Voice-first, which reaches registrants email misses
- HIPAA-capable with a BAA, useful for healthcare-adjacent SaaS
- Usage-based credits keep costs proportional to volume
- Live tech support rather than a self-help-only model
Cons
- One-way reminders; no conversational confirmations or rescheduling
- Not designed for complex event workflows like session switching
- Pricing details beyond the credit model require contacting the vendor
Best for: Teams that want simple, reliable automated voice and SMS reminders without building an AI agent, especially where compliance support matters.
The gap between registrations and attendees is where SaaS webinar programs quietly lose money. Cloud Present's research pegs average live attendance at 40 to 50 percent, and the same source notes that 73 percent of B2B webinar attendees become qualified leads, so every extra person on the call has real pipeline value. A reminder call sequence, layered on top of your email sends, is one of the cheapest ways to close that gap. If you want the whole thing handled, My AI Call Center runs Event & Webinar Reminder Calls as a managed campaign against your approved, permissioned attendee list, starting at 9¢ per connected minute with the full cost quoted before launch. The first campaign review is free, and you'll know the total before you approve anything. If you'd rather build it yourself, Retell AI's reminder template or Call Loop's voice broadcasts are honest alternatives. Either way, don't leave show-up rates to email alone.

Frequently asked questions
Why use reminder calls instead of just sending more emails?
Email reminder sequences work, but they're crowded. Research collected by Nitrosend shows that only about 18 percent of SaaS webinar emails are reminders, and most registrants get buried. A short call one or two days before the event reaches people who never open the email, confirms attendance directly, and gives them an easy way to reschedule instead of silently no-showing. We Thrive Together's event reminder guide specifically recommends personal calls one to two days before an event for exactly this reason.
What makes My AI Call Center different from the other options on this list?
It's a managed service rather than software. You buy a campaign with one clear goal, quoted before launch, and their team runs it against your approved, permissioned, or reviewed list. They check list source and consent records before anything launches, route outcomes back into your CRM, and report actual results with disposition codes rather than inflated numbers. Calling starts at 9¢ per connected minute with the rate locked for the campaign, and there are no per-seat charges.
How many reminders should a SaaS webinar get?
Attendir's research on event reminder sequences recommends four email sends for B2B events: one week out, one day out, one hour out, and one at start time. A reminder call slots in best one to two days before the event, layered on top of that email sequence rather than replacing it. My AI Call Center supports same-day, day-before, or multi-touch call windows so you can match the timing to your audience.
Is it legal to use AI voices for reminder calls in the US?
AI-generated voices are treated as artificial voices under the TCPA, which means prior express consent is required, along with state-specific quiet hours, day restrictions, and registration rules. My AI Call Center discloses AI on every call, honors keyword opt-outs like STOP and REVOKE, and logs DNC requests across all campaigns. Their disclaimer notes that requirements vary by location, industry, and consent status, and clients are responsible for obtaining appropriate legal guidance before launch.
Can reminder calls handle registrants who can't attend?
Yes, depending on the tool. My AI Call Center routes outcomes back to your team, so a registrant who can't make it becomes a follow-up request in your CRM. Retell AI's template goes further, with backend functions to move a registrant to the next available session or cancel their registration outright, falling back to email or web cancellation if the backend action fails.
What does a managed reminder call campaign cost?
With My AI Call Center, calling starts at 9¢ per connected minute, tiered by volume, and the rate is agreed before launch and doesn't move mid-campaign. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before you approve. There are no per-seat charges, no platform bill, and no minimums you didn't choose. The first campaign review is free.
