ThreatPhishing & impersonation

Fake Calendly / Acuity Scheduling subscription payment failed, booking links and scheduling suspended, or appointment calendar inactive phishing — fraudulent email impersonating Calendly or Acuity Scheduling claiming the subscription payment has failed, booking links are no longer active, or appointment scheduling and client calendar are suspended — Calendly: 10M+ users, 50K+ paying ($10-20/month Standard/Teams); Acuity Scheduling: 100K+ users ($20-61/month); all booking links go dark simultaneously — service businesses lose all new appointment acquisition and existing scheduled appointments become inaccessible

What this tier means

High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.

How Gorganizer detects this

Phishing emails impersonating Calendly or Acuity Scheduling claiming the scheduling subscription payment has failed, booking links are no longer active, or appointment scheduling and client calendar integrations are suspended — directing them to update billing or restore scheduling access through a credential-harvesting portal. Key facts: (1) Scheduling platform suspension instantly breaks all booking links published across the subscriber's digital presence: Calendly serves 10M+ users with 50K+ paying customers ($10-20/month Standard/Teams) who embed scheduling links in email signatures, LinkedIn profiles, website contact pages, social media bios, and direct outreach messages; when a Calendly subscription lapses, every booking link the user has ever shared returns an error — prospects who click the email signature link, clients who try to book a follow-up, and new leads from website contact forms all hit a dead scheduling page simultaneously; for sales professionals, consultants, and service businesses whose entire client acquisition flows through Calendly, this is a complete top-of-funnel failure; (2) Calendly's routing forms and team scheduling features create organizational urgency: Calendly Teams ($16/seat) enables enterprise-level scheduling routing that directs incoming bookings to the right team member based on availability, skills, and territory — a suspended Teams account breaks the entire scheduling router, making all inbound meeting requests fail across the organization; sales and customer success teams that rely on Calendly routing for lead distribution lose all automated meeting assignment; (3) Acuity Scheduling's service business focus creates appointment-dependent revenue urgency: Acuity Scheduling serves 100K+ service businesses ($20-61/month Emerging/Growing/Powerhouse) including therapists, coaches, fitness trainers, salons, and tutors who collect appointment payments through Acuity; a suspended Acuity account not only breaks appointment booking but also disables the integrated payment collection that clients use to pay for sessions — service businesses lose both booking capability and payment processing simultaneously; (4) Scheduling platform suspension affects all past-shared booking links retroactively: unlike a website outage where only current visitors are affected, a Calendly suspension breaks every link ever shared — a consultant's signature link sent two years ago to a returning client now fails; the retroactive nature of booking link failure means the impact compounds over time as more previously-shared links encounter the suspension; (5) Scheduling accounts contain contact information for all clients and prospects who have ever booked appointments, meeting preferences, integrated calendar access tokens, and payment information for service deposits. Warning signs: sender not calendly.com or acuityscheduling.com; scheduling billing is managed in account settings, never via email link.

False-positive guard

Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.

About the scoring engine

Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.

Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
