The only bulk messaging platform that requires zero identity. Pay with crypto. No KYC. No middlemen. No monthly fees.
You are only charged for messages that are actually delivered.
Full delivery receipt for every message. Proof of delivery on every send.

Unlike other platforms that charge you per send regardless of outcome, FlushIt refunds credits for every bounced, failed, or undelivered message. Your money goes to actual deliveries — not wasted sends.
Every email and SMS you send comes with a detailed delivery receipt. No black boxes. No guesswork. You see exactly what happened.
Every single recipient gets their own delivery status — sent, delivered, bounced, or failed. Not just batch averages.
Download your delivery reports anytime. Use them as proof of delivery for clients, partners, or your own records.
If a message fails or bounces, the credit is automatically returned to your balance. You see the refund right in your receipt.
