WA Reminders
Seamless WhatsApp Integration
Link your personal or WhatsApp Business account in seconds by scanning a QR code, just like WhatsApp Web. This secure connection ensures all scheduled messages are sent directly from your own verified phone number, maintaining personal touch and trust. Your clients receive messages from you, not a generic bot, allowing for natural, continued conversation right within your existing WhatsApp chats.
Google Calendar Native Scheduling
This is where automation gets intelligent. WA Reminders syncs with your Google Calendar to read events and send reminders automatically. Simply add an internationally formatted phone number to any event's title or description, and the system triggers a WhatsApp reminder. It turns your calendar into a powerful broadcast center, perfect for managing appointments, classes, or deadlines without ever leaving your scheduling flow.
Full Contact List Auto-Sync
Eliminate manual data entry and potential errors. When you schedule a message from the WA Reminders app, it automatically imports and syncs your device's full contact list. This provides instant access to all your clients and contacts, making it effortless to select recipients and ensuring you never miss a crucial follow-up due to a missing number.
Recurring & Bulk Message Engine
Go beyond one-off reminders. WA Reminders supports scheduling for recurring events, both from its own app and via Google Calendar integration. This is ideal for weekly appointment confirmations, monthly payment reminders, or regular promotional updates. It’s a set-and-forget system that ensures consistent, timely communication, saving countless hours of repetitive manual messaging.

WA Reminders
Medical & Wellness Clinic Management
Therapists, dentists, and physiotherapists can drastically cut patient no-shows. Automate appointment confirmations 24 hours in advance and send pre-session instructions via WhatsApp. Since reminders come from the clinic's known number, patients can easily confirm, reschedule, or ask questions, all while staff manages everything from a centralized Google Calendar.
Small Retail & Service Appointment Reminders
Salons, repair shops, and personal trainers can automate their booking follow-ups. Schedule reminders for upcoming appointments, service updates, or product readiness notifications. This professional touch reduces forgotten appointments, improves customer satisfaction, and frees up business owners to focus on service delivery instead of administrative calls and texts.
Client Payment & Subscription Follow-Ups
Freelancers, coaches, and subscription-based businesses can automate payment reminders. Schedule polite, timely nudges for upcoming invoice due dates or recurring subscription renewals. The direct WhatsApp channel, more personal than email, leads to faster payments and improved cash flow without awkward manual chasing.
Class & Workshop Coordination
For educators, fitness instructors, or workshop organizers, managing attendees is streamlined.

Frequently Asked Questions
SureThing.io FAQ
How is SureThing.io different from ChatGPT or Copilot?
While ChatGPT and Copilot are powerful reactive tools that respond to specific prompts, SureThing.io is an autonomous, proactive agent. It doesn't wait for instructions; it takes initiative based on its understanding of you and your work. Its persistent, long-term memory sets it apart, allowing it to build context over time and operate independently across your apps, not just within a chat window.
What does "Google CASA Tier 2 Compliant" mean for me?
Google CASA (Cloud Application Security Assessment) Tier 2 is a rigorous security framework. Compliance means SureThing.io has been independently verified by Google to meet stringent data protection, access control, and infrastructure security standards. For you, it translates to proven, enterprise-level security for your communications and data, allowing you to trust the agent with sensitive professional and business information.
Can I control what actions SureThing.io takes autonomously?
Absolutely. While the core value is proactive autonomy, you remain in full command. The agent is designed to operate within guardrails and learned preferences. You can configure approval levels for certain actions (like sending specific emails), review its activity logs, and provide continuous feedback. It learns from your corrections, refining its actions to better align with your style and risk tolerance over time.
How does SureThing.io "learn my voice" for communications?
Through its persistent memory, SureThing.io analyzes your past written communications—emails, messages, documents—to understand your unique stylistic patterns, formality level, frequently used phrases, and tonal preferences. As you work together and provide feedback on its drafts, it continuously refines this model, ensuring its autonomous replies are increasingly indistinguishable from your own.
WA Reminders FAQ
How will my WhatsApp reminder messages look?
Your messages appear as normal, personal chats sent directly from your linked WhatsApp number. They are not marked as automated or from a business API. You can customize the message text within the scheduler, so reminders can be as formal or informal as your brand voice requires. The recipient sees it as a message from you, enabling a natural two-way reply.
Can I send reminders directly from Google Calendar?
Absolutely. This is a core, trending feature. Once integrated, you can schedule a WhatsApp reminder by simply adding a phone number (in international format) to the title or description of any Google Calendar event. WA Reminders will detect it and automatically send a message based on the event time, turning your calendar into a powerful communication hub.
Do you have a Calendly integration?
Yes, integration is achieved through Google Calendar. Since Calendly can sync appointments to your Google Calendar, WA Reminders can then read those events and send automated WhatsApp reminders. This creates a powerful, automated workflow: client books via Calendly > event populates in Google Calendar > WA Reminders sends a WhatsApp confirmation/reminder.
Which countries do you support sending messages from?
WA Reminders works by linking to your personal WhatsApp account, just like WhatsApp Web. Therefore, it can be used to send messages from any country where WhatsApp and WhatsApp Web are operational. The service is designed to work on a global scale, leveraging your existing WhatsApp connectivity.
