Verify emails, pay with crypto

CharlyMail is an email verification service that accepts cryptocurrency. Pay with USDT, Bitcoin, Ethereum or TRX — no credit card, no KYC, no monthly plan. Verification costs $0.00049 per address, which is $0.49 per 1000.

No credit card required

Every major email verification service — ZeroBounce, NeverBounce, Bouncer, MillionVerifier — requires a payment card or a PayPal account. That rules out a lot of legitimate users: freelancers in countries where Stripe does not operate, agencies that keep marketing spend separate from corporate cards, and anyone who simply does not want a recurring charge sitting on their card.

CharlyMail takes crypto instead. You top up a token balance, tokens are spent as you verify, and nothing renews automatically. There is no card on file because there is no card at any point in the process.

What you need to sign up

• A Telegram account — that is the entire registration flow.
• No email confirmation, no phone number, no billing address.
• 200 free tokens are credited on signup, enough to verify 200 addresses.

How USDT payment works

Payments run through our own processing setup on DV.net, not a third-party checkout. When you top up, the service generates a deposit address for the coin and network you picked. You send the amount, and the balance is credited automatically after the transaction confirms on-chain.

1. Open the balance page and choose an amount — minimum $5, maximum $5000.
2. Pick a coin and network. A unique deposit address is generated for that specific payment.
3. Send the funds from any wallet or exchange.
4. Tokens land on your balance once the network confirms. Typically minutes on TRON, longer on Bitcoin.

Which coins we accept

USDT on TRON (TRC-20) is the cheapest option in practice — network fees are a fraction of a dollar and confirmation takes a couple of minutes. USDT on Ethereum works the same way but costs more in gas, which matters on smaller top-ups.

Why no KYC

Identity verification exists to satisfy card networks and banking regulators. Crypto payments settle directly on-chain, so that requirement does not apply to us. We do not ask for documents, we do not run identity checks, and we do not store a legal name or address, because none of that is needed to move a token balance.

This is a structural difference, not a policy we could reverse next quarter. A service that charges cards has to collect this data. A service that takes crypto does not.

What you get for $0.49 per 1000

The price covers more than a yes/no answer on deliverability. Every verified address comes back enriched:

• Validity — syntax, MX records, disposable-domain detection, role-address detection.
• Identity — first name, last name and gender inferred from the address structure, across a 6700+ name dataset covering 40+ regions.
• Context — country, mail provider, domain type (corporate, personal, ISP, education), Gravatar avatar when one exists.
• Score — a 0–100 quality score you can filter and sort on.

Deep SMTP verification — an actual handshake with the receiving mail server — is optional and costs 5 tokens per address. The point of keeping it separate is that you run it only on the addresses that survived the cheap checks, which is where the 3–4× cost saving comes from.

Common questions

Can I verify emails without a credit card?

Yes. CharlyMail accepts USDT, BTC, ETH and TRX. No card is required at signup or at payment.

Is the payment anonymous?

There is no KYC and no identity document collection. Registration needs a Telegram account only. Blockchain transactions themselves remain public on their respective networks — that is a property of the chain, not of our service.

Is there a subscription?

No. Tokens are bought once and spent as you use them. Nothing renews, and an unused balance does not expire. Competitors like ZeroBounce start at $99 per month regardless of how much you actually verify.

What happens if I send the wrong amount?

The balance is credited according to the USD value received. Underpayments below the invoice amount are held for review rather than silently dropped — contact support with the transaction hash.
