Looking to pay for SMTP with Monero? KingSMTP is one of the only transactional email services that accepts XMR — alongside Bitcoin and USDT. No KYC, no credit card, no identity verification required.
Why pay for SMTP with Monero?
Unlike Bitcoin, Monero transactions are fully private by default. The sender, receiver, and amount are all hidden on the blockchain — making XMR the strongest privacy option for businesses that want no financial paper trail.
- Bitcoin transactions are traceable — wallet addresses and amounts are visible on the public blockchain
- Monero is private by design — ring signatures, stealth addresses, and RingCT hide all transaction details
- No link between payment and account — your XMR payment cannot be connected back to your identity or business
- No banking restrictions — pay from anywhere in the world, no SWIFT, no IBAN, no chargebacks
Why KingSMTP?
- Pay with XMR, BTC, or USDT — no credit card needed
- No KYC required — no ID, no address, no verification

- 99% inbox rate — clean IPs, DKIM and SPF included
- Free 7-day trial — no payment required to start
- Email routing (MX) included — send and receive on your own domain

Among legitimate transactional email providers, yes. Most SMTP services only accept credit cards. A handful accept Bitcoin. KingSMTP is one of the only providers focused on transactional email that accepts XMR.
Do I need to create an account to pay with Monero?
Yes — you create an account with just an email address and domain. No name, no address, no ID required.
Is there a free trial before I have to pay with Monero?
Yes — 7 days free, no credit card and no crypto payment required to start.
What other cryptocurrencies does KingSMTP accept?
Bitcoin (BTC), USDT (TRC-20 and BEP-20), and Monero (XMR).
Will my Monero payment be linked to my account?
No. Payments are processed separately from your account activity. There is no KYC step that would link your XMR wallet to your identity.
