About

CalNudge is an automated RSVP reminder service that helps meeting hosts stop chasing calendar confirmations. The product connects to a user's Google Calendar or Microsoft Outlook account, monitors the meetings they organize, and sends polite reminder emails to attendees who have not responded — without manual setup per meeting. Reminders stop automatically the moment a recipient accepts or declines.

CalNudge addresses a problem most meeting hosts face every week: invite recipients who never respond. Without a clear yes-or-no, hosts cannot plan, redirect their time, or anticipate no-shows. Manually chasing each non-responder is time-consuming and awkward. CalNudge handles it automatically on a configurable cadence — default reminders go out one week, two days, one day, and six hours before the meeting — alongside a live dashboard showing the RSVP status of every attendee across every upcoming meeting.

Key features include a daily digest email summarizing the day and week ahead, post-meeting feedback surveys, attendance analytics tracking response rates and no-show trends, and four customizable reminder tone presets — Polite, Firm, Casual, and Formal — that let users match the voice of their reminder emails to their audience. Every reminder is sent from the host's name "via CalNudge," so attendees see a familiar sender, and replies route directly to the host.

CalNudge offers a Free Forever plan with unlimited active events, the daily digest, automatic reminders, and the live dashboard. The Pro plan, priced at $10 per month or $99 per year, adds custom reminder timing, post-meeting feedback surveys, attendance analytics, and the four reminder tone presets. Every new signup includes a 30-day Pro trial that automatically converts to Free Forever — no credit card required.

The product is designed for sales teams, recruiters, consultants, founders, and SaaS operators who run meetings with external participants and lose time to non-responders and no-shows. Setup takes under 12 seconds: users sign in with their Google or Microsoft account and CalNudge begins monitoring meetings immediately.

CalNudge was founded by Michael Vanderslice and is built and maintained as an independent SaaS, with active development driven by user feedback during early access.
