Billing

Last updated 2026-09-28 · applies to Envelt at envelt.com

Summary. Paid plans are prepaid in USDT for 1 to 24 months. You send an exact amount to our address; the plan activates when the transfer confirms. No subscriptions, no auto-renewal, no card, no invoice with your name on it. Active plans are not refundable.

1. Plans and prices

Plan	Price	Storage	Addresses	Custom domains	Mail apps
Free	Free	10 MB	1	No	No
Plus	8 USDT / month	1 GB	10	Yes	Yes
Pro	20 USDT / month	5 GB	50	Yes	Yes

Prices are in USDT (Tether) and exclude any network fees, which you pay to the network. Prices may change; a change never affects a period you have already paid for.

2. How to pay

Choose a plan, a network (the configured networks) and a number of months in the Account page.
You receive an invoice with an exact amount (for example 8.4471 USDT). The fractional part identifies your payment. Send exactly that amount from any wallet to the address shown.
When the transfer has enough confirmations, the plan activates automatically and the invoice is deleted. Paying again before expiry extends the period.

3. Invoice validity and mistakes

An invoice is valid for 48 hours. Transfers received after expiry, or with a different amount, are not matched automatically.
If you sent the wrong amount, the wrong token, or to the wrong network, contact billing@envelt.com with the transaction hash. We will credit the plan where we can identify the transfer. We cannot recover funds sent to the wrong network or the wrong address.
We keep no transaction hashes once a plan is credited. If you need proof of payment, keep your own wallet record.

4. Refunds

Because payments are anonymous and plans are prepaid, an active plan cannot be refunded. If we discontinue the Service or permanently fail to provide a paid feature, we refund the unused portion to a wallet address you provide. Consumers in jurisdictions that grant a statutory withdrawal right waive it by requesting immediate activation of the plan.

5. Expiry

When a paid period ends, the account returns to the free tier. Your mail, addresses and domains are kept. New mail beyond the free quota is refused with a temporary error so senders retry; addresses and domains beyond the free limits remain but cannot be added to. Renewing restores everything.

6. Taxes

Prices are shown without VAT. Where Switzerland VAT applies to a consumer sale, it is included in the displayed price. Business customers are responsible for any taxes due in their jurisdiction.

7. Receipts and business customers

We do not issue named invoices by default, because we hold no name. Business customers who need a receipt can request one from billing@envelt.com by quoting the invoice id and transaction hash within 30 days of payment.
