[TT-028] Docs/error text still say hosted email sends from tacko.io (BILLING.md, contact.ts) after #845 #859
Description
TT ID: TT-028 · Severity: P2 · Found by: QA · Area: Docs / Email
Agreed sender for ALL automated TT emails: From Telemetry Tracker <info@telemetry-tracker.com>, Reply-To info@telemetry-tracker.com. #845 (v1.22.11) fixed the example sender but left operator-domain instructions pointing at tacko.io. Present on both develop (3f0b111) and main.
| Location | Current | Expected |
|---|---|---|
| docs/BILLING.md:54 | "The hosted cloud sends from tacko.io (operator domain). telemetry-tracker.com is the app URL, not the mail-from domain." |
hosted cloud sends from telemetry-tracker.com (info@) |
| docs/BILLING.md:56-57 | Resend → Add domain tacko.io, DNS records for tacko.io |
telemetry-tracker.com (SPF/DKIM/DMARC) |
| docs/BILLING.md:138 | checklist "Resend domain verified (tacko.io or your sending domain)" |

| apps/api/src/routes/contact.ts:83 | error text "verify tacko.io (or your sending domain) in the Resend dashboard" | "verify your sending domain (hosted: telemetry-tracker.com)" |
Live production check (not a bug, for the record), 2026-10-21 CEST, raw headers 2/2 each:
- Password reset (08:57:00Z, 08:57:21Z):
From: Telemetry Tracker <info@telemetry-tracker.com>,Reply-To: info@telemetry-tracker.com, DKIM d=telemetry-tracker.com ✅ - Org invite (2 fresh invites, revoked after): same From/Reply-To ✅
- Alert (evaluator, 2026-10-20 08:45Z–11:35Z, 4 mails): same From/Reply-To, DKIM d=telemetry-tracker.com ✅
- Older mails up to 2026-10-16 were
Telemetry <noreply@tacko.io>, no Reply-To (pre env change).
Code: every send goes through sendTransactionalEmail (apps/api/src/lib/email.ts:128 TELEMETRY_EMAIL_FROM, :129 Reply-To default); no hardcoded From found. Live From depends on Railway env TELEMETRY_EMAIL_FROM on API and alert-rules-evaluator; Reply-To default depends on TELEMETRY_DASHBOARD_ORIGIN / TELEMETRY_EMAIL_REPLY_TO. Stripe's own receipts/invoices (if enabled) are configured in Stripe account settings, not code; not verified (no payment made).
Acceptance: no tacko.io sender/domain instructions in docs/BILLING.md or contact.ts error text on develop and main.

fix(api): contact error text names telemetry-tracker.com (Refs #859)
docs(env): example sender info@telemetry-tracker.com (Refs #859)
docs: replace leftover tacko.io sender references (TT-028) (#861)

QA verification 2026-10-23 09:30 CEST, production v1.22.13 (release #865). Acceptance met: no tacko.io sender/domain instructions remain in docs/BILLING.md, apps/api/src/routes/contact.ts or apps/api/.env.example on main (63a2d7d) and develop; BILLING.md now says the hosted cloud sends from telemetry-tracker.com (info@telemetry-tracker.com). Live mail From/Reply-To was already correct (verified 2026-10-21). Verified and closed (TT-028).
