Bitcoin bundles
Or name your own amount from $1 to $100 — pass usd instead of a bundle. The network fee is the same whatever the size of the payment, so it eats a far larger share of a small one. Paying in USDT instead? Send any amount — $1 buys 10 credits.

Pricing questions
Do credits expire?
No. A credit sits on the account until an inbox is created with it. There is no monthly reset and no subscription to keep alive, so bursty use never pays for idle months.
What exactly consumes a credit?
Creating an inbox costs one, and keeping an inbox permanently costs 30. Receiving messages, listing them and reading them are all free, so one inbox that receives fifty emails still costs a single credit.
Is a $1 Bitcoin payment worth it?
It works: the $1 bundle buys 10 credits, the same rate as USDT. But the network fee is the same whatever the size of the payment, so on a $1 purchase it can cost more than the credits. Bigger bundles, or USDT, keep the fee a small share.
Can I pay with a credit card?
No. Payment is in Bitcoin or USDT through Blockonomics, with no card on file and no KYC step.
Are purchases refundable?
No. Quota purchases are non-refundable, which is why the free tier exists: 5 inbox credits are enough to test the whole flow before spending anything.
What happens when I run out of credits?
Inbox creation starts failing while existing inboxes keep receiving mail. Buying another bundle restores creation immediately, and unused credits carry over.
Do inboxes expire?
Thirty days after creation, then it stops receiving mail. For a one-off verification code that is plenty. If the address signed up for an account you will keep, keep the inbox permanently for 30 credits, once: password resets keep arriving, and an address is never given to anyone else, so an expired one can still be restored.
How long are messages kept?
Seven days, then they are deleted automatically. There is no storage tier to buy and no cleanup job to run.
