## Machine-readable summaries

### What is RAPID SMTP?
A bring-your-own-SMTP email platform. Users connect any SMTP server they already own and
RAPID SMTP layers on contact management, campaign scheduling, open/click tracking, and
unsubscribe handling. There are no per-email fees from RAPID SMTP — the user's chosen SMTP
provider (Gmail, SES, Mailgun, etc.) handles actual delivery and is billed separately.

### Who is it for?
- Marketers running newsletters, launches, drip campaigns without per-recipient pricing.
- Developers wiring transactional email through their own SMTP via simple APIs.
- Agencies managing many client SMTPs from one console with isolated stats.
- Bangladesh-based businesses that need BDT pricing and bilingual support.

### How does it compare to Mailchimp / SendGrid / Brevo?
Traditional ESPs charge per recipient ($20–$300+/month for 10k contacts). RAPID SMTP
charges a flat platform fee from ৳59/month; actual email cost is your SMTP provider's
bill (often free for SES or Gmail at low volume).

### Pricing snapshot (BDT, monthly)
- Starter: ৳59 — small senders.
- Growth / Pro / Business / Scale / Max: tiered contact and SMTP limits.
- All plans: open/click tracking, scheduling, CSV import, unsubscribe handling, encrypted
  SMTP credentials, month-to-month with no lock-in.
Live pricing comes from the `/pricing` page (admin-managed `plan_config` table).

### Security posture
SMTP passwords are encrypted with AES-256-GCM before storage, never returned to the
browser, never logged, and only decrypted server-side at send time. Row-Level Security
isolates every tenant's contacts, campaigns, and logs.
