We're honest about email quota.
THO Alerts runs inside your Google account via Apps Script. Emails come from your address (high deliverability) but are bound by Google's daily limit — 100/day Gmail or 1,500/day Workspace. We can't lift this; nobody can.
That's why our 50,000/month Pro quota is for webhook channels — Slack, Discord, Telegram, Teams, Zapier, Make, n8n. No per-account cap. Fire 10k/day to Slack without breaking a sweat.
Simple. Lifetime.
No subscription. No surprise renewals. Ever.

Common questions
How does it work? +
Install from Google Workspace Marketplace, define rules (sheet + range + condition + channel + recipient), and THO Alerts watches your sheet via Google's native onEdit trigger. The moment a matching cell changes, the alert fires — usually under 2 seconds.
Does it work with IMPORTRANGE / formulas / API writes? +
Yes — enable Scheduled Check (hourly/daily/weekly) for changes that don't trigger onEdit (formula recalcs, API writes from external scripts, IMPORTRANGE refreshes).
Why $79 lifetime, not subscription? +
We hate subscription fatigue. Pay once, own it forever. Lifetime updates included. Even compared to the cheapest monthly competitor, $79 beats them by year 2.
What about email deliverability? +
Excellent — emails come from your Gmail/Workspace address with native authentication (SPF/DKIM). The trade-off: bound by Google's daily quota (100/day Gmail, 1500/day Workspace). For higher volume, use webhook channels.
Is my data safe? +
Yes. For webhook alerts, data never touches our servers — Apps Script POSTs directly from your Google account to your webhook URL. License validation only transmits your license key.
Refund? +
