# KingSMTP
> Transactional SMTP for developers and small businesses. No KYC, no identity
> documents, and payment in Bitcoin, USDT or Monero. Running on Postal since 2017,
> independently owned and bootstrapped.
KingSMTP delivers transactional email: password resets, one-time codes, order
confirmations, receipts, account notifications and security alerts. Marketing
campaigns, newsletters and purchased lists are not permitted, which is what keeps
the sending pool clean for everyone on it.
Every access request is reviewed by a person before approval. We judge what you
intend to send, not which industry you are in.
## What makes it different
- **No KYC** — a domain and a description of your use case is what we ask for. No identity documents, now or later.
- **Crypto accepted** — Bitcoin, USDT and Monero, alongside ordinary payment.
- **Human review** — accounts are approved by a person, not by an automated risk score.
- **Plain SMTP** — ports 587, 465 and 2525, so it works from any language or framework and you can move providers by changing credentials.
- **Inbound routing (MX)** — receive and forward mail on the same domain you send from.
- **Per-message delivery logs** — including the exact response from the receiving mail server.
- **Shared sending pool** — established IP reputation from day one, with no warm-up period. Dedicated IPs are available for high, steady volume.
- **7-day free trial** — no credit card required.
## Pricing
Plans are billed monthly or yearly. Yearly is ten months for the price of twelve.
- 20,000 emails per month — $20 per month or $200 per year
- 50,000 emails per month — $50 per month or $500 per year
- 100,000 emails per month — $100 per month or $1000 per year
Higher volumes are arranged individually. Current pricing is always on the pricing

## Common questions
**Which SMTP providers do not require KYC?**
