How OTPGmail Works: Rent an Inbox, Buy a Gmail Account, Use the API

Last updated October 13, 2026

OTPGmail works in two ways: you rent a real Gmail or iCloud inbox to receive a verification code, or you buy a short-lived Gmail account outright so you can sign in to it. Renting an inbox gives you the code, not the login; buying a short-lived Gmail account gives you the login, not a long-term mailbox. If a rental gets no code within the waiting time (25 minutes at most), it cancels itself with a 100% refund.

The short version

Rent an inbox for a verification code

1. Create an account with an email address, a username and a password. Sign-up costs nothing; your balance starts at zero.
2. Top up by Vietnamese bank QR, USDT/USDC or Binance ID (see top-ups).
3. Pick the service and inbox type, @gmail.com or @icloud.com. A service can be sold from several stock sources (shown as "warehouses" on the rental page), each with its own price, stock and code rules; the rental page preselects the cheapest source in stock and shows its rules before you confirm.
4. Rent to get a real address. If the service is out of stock when you rent, you are not charged.
5. Paste the address into the site you are verifying and ask it to send the code.
6. Read the code when it appears on your order page. At some sources, if the system cannot extract a code, you can still open the full email with the "View" button. The order is complete once the first code arrives.

Handing an address to a teammate or a client? Switch on a share code on your Account page: they enter it together with the email at otpgmail.net/otp to see the codes without an account. Viewing codes there never charges you; renting a cancelled address again through the link works only if you allow it on the Account page, and then it is charged to your balance.

If the code does not arrive

• While you wait: the order shows "Waiting for code" for up to 25 minutes; some sources use a shorter waiting time, shown on the rental page before you confirm.
• Before the first code: you can cancel at any time and get 100% back to your balance immediately.
• When the waiting time ends: the order cancels itself and 100% goes back to your OTPGmail balance, usually within a minute — no need to contact support.
• Once the first code has arrived: the order can no longer be cancelled or refunded, even if you never use the code.

A few services have their own rules, shown on the rental page before you confirm and applied instead of the default — for example a fixed 75-minute window, at most 4 emails, no cancellation and no refund if nothing arrives. Full details are in the refund and warranty policy.

More codes after the first

After the first code, more codes can arrive only if the service sends more than one code per inbox — many send just one. Extra codes cost nothing within the order period when the service sends more than one; the limit and time window depend on the stock source and are shown before you confirm. At some sources, once the no-charge window has ended, the "Get new code" button opens more time for 50% of the rental price, charged only after you confirm. Details: extra codes.

Bulk rental

Bulk rental: 1 to 200 inboxes per batch at the same unit price as a single rental, kept for 24 hours. Gmail batches give each inbox its own code link for scripts; iCloud batches are read on the batch page or through the API. Inboxes that receive no code are not refunded; only a shortfall or a batch that cannot be bought is refunded. Batches are bought on the bulk rental page only; the API can list batches and read their codes.

Buy a short-lived Gmail account

1. Log in to OTPGmail, open the "Buy short-lived Gmail" tab, read each type's description and stock, and pick a type.
2. Choose a quantity, read the terms, tick "I have read and accept the terms" and buy; the price comes out of your balance.
3. The system buys from the source the moment you click and delivers within seconds to a few minutes. Larger orders arrive progressively; view them again and download a .txt file under the History tab.
4. Sign in right away, depending on the type: with the email and password, by importing the cookies into your browser, or with the quick login link. Open a link in a desktop browser and wait about 10 seconds; each link works about 2–3 times, and opening it repeatedly can trigger a temporary block. The "fresh" type is signed in through the Gmail app.
5. If your first sign-in within 2 hours of purchase fails, contact support with the order ID for a replacement account or a refund to your balance, depending on stock.

Short-lived Gmail accounts last only a short time, and how long depends on the type (some last less than an hour), so read the type description before buying and use the account as soon as it arrives. If fewer accounts are delivered than you paid for, or the purchase cannot be completed, the missing part is refunded to your balance automatically. Google is tightening captcha checks on short-lived Gmail accounts and OTPGmail does not solve captchas; if your tool cannot handle a captcha, do not buy. See the first-sign-in warranty.

Use the API

A REST API with a personal key per account: list services and stock sources, create orders, poll every 3–5 seconds for the code, cancel for a refund before a code arrives; by default up to 20 requests per second and 900 per minute. One request rents up to 200 inboxes. Send an Idempotency-Key when you create orders so a retry never rents twice; when stock runs out, the API returns NO_MAILS_AVAILABLE or OUT_OF_STOCK and charges nothing. Bulk rentals are bought on the web only; short-lived Gmail accounts can be bought on the web or through the API (/v1/mail-shop). Public documentation: API documentation.

Top up your balance

Top up by Vietnamese bank QR transfer, USDT or USDC on many networks, or Binance ID; deposits are credited automatically, even if you leave the page. OTPGmail adds no top-up fee; network or exchange withdrawal fees are paid by the sender, and the USDT/USDC rate is shown and locked when you create the order. Per-payment limits are shown on the top-up page; for USDT/USDC, send the exact amount in the right coin on the right network. Your balance never expires, can be used only inside OTPGmail and is not paid out as cash.

Where inboxes come from and how the code reaches you

OTPGmail does not create mailboxes itself: inboxes and accounts come from third-party suppliers (some are iCloud inboxes that OTPGmail buys access to and manages itself). Mail arriving at a rented inbox is read automatically to extract the code or verification link; emails in an unfamiliar format may be analysed by an AI language service to create extraction rules. An iCloud inbox can be used by several customers for different services, but each customer sees only the email from the service they rented. Details are in the privacy policy.

Frequently asked questions

How long does a code take to arrive?

It depends on the service. Each service page shows its typical time to a code and its 30-day delivery rate; if no code arrives within the waiting time (25 minutes at most), the order cancels itself with a 100% refund.

Can I read every email in a rented inbox?

Usually not: a rental shows the code or link from the service you chose, and some stock sources also show that service's full email. The iCloud version of "Any service" is the exception: it shows every new email sent to the inbox for 24 hours and only gives you inboxes you have never rented before.

Should I rent one inbox, rent in bulk or buy an account?

Rent a single inbox for one verification code. Rent in bulk when a script needs many inboxes at once. Buy a short-lived Gmail account when you must sign in to a Google account for a short time. Use the API to automate. Prices for each are on products and price ranges.
