1SecMail

Overview

1SecMail is a temporary-email service for people who need a disposable address without creating an account. It is best for routine, low-stakes sign-ups where choosing an alias or retrieving an attachment is useful. Its short-lived, unprotected inbox makes it a poor fit for sensitive accounts.

Key features

You can create a mailbox without registration or sharing personal information, then send and receive messages. Custom aliases let you choose an address rather than use the default, and attachment downloads are handy when a temporary inbox receives a file. These conveniences do not change the core trade-off: the service warns against using public temporary addresses for sensitive or financial information, and inbox protection is listed as none.

Retention calls for caution. The inbox lifespan is described as minutes, while the one-time-email guide says addresses and related messages are usually erased after 24 hours. Treat messages as fleeting and download any attachments promptly; do not rely on the mailbox as an archive.

1SecMail says it collects no personal information and automatically deletes transient email. Its published API documentation covers domains, creating, updating and deleting email, retrieving messages, and downloading attachments. That may interest developers, but the API-key feature is still under development, so the documented endpoints are not a reason to assume private API access is ready.

Pricing

The free plan costs nothing and includes 3 own domains, 3 inbox records, 3 saved messages, premium support, attachment viewing, and premium domains. It is a reasonable starting point for occasional use, but the small record and saved-message caps limit how much you can keep. Premium domains include 1secmail.cc, 1secmail.website, and 1secmail.live.

Standard costs $4.99 a month and raises the allowances to 5 own domains, 30 inbox records, and 30 saved messages. Premium costs $9.99 a month, with 10 own domains and 50 inbox records and saved messages. Both retain premium support, attachment viewing, and premium domains; Standard suits more regular use, while Premium is for people who need more capacity. Neither changes the caution around sensitive mail.

Gold costs $35.99 a year and provides 20 own domains, 500 inbox records, and 500 saved messages. Diamond costs $45.98 a year and makes own domains, inbox records, and saved messages unlimited. These yearly plans suit heavier use where the monthly plans' quotas would be restrictive; their value depends on needing that extra capacity.

Pro API Key costs $10 a month and promises unlimited requests subject to a fair usage policy, faster response times, private API key access, and developer-friendly access. It is aimed at developers and companies, but the API-key feature is under development, so buyers should not treat the plan as a ready integration without that access.

Platforms

1SecMail is available on Android and the web, with a Chrome Web Store extension for quick access to temporary email. An API is also part of its offering, though API-key access remains under development. This spread covers casual browser and phone use, but the API caveat matters for anyone planning a software integration.

Who it's for

Choose 1SecMail for throwaway addresses used with routine sign-ups, especially if you want to set an alias or retrieve a file before the inbox expires. It is less suitable when you need lasting message history, protected mail, or a dependable private API integration. For general questions and technical assistance, support is reachable at [email protected].

Pros and cons

• Pros: No registration and no personal details required. You can create a temporary inbox for low-stakes sign-ups without setting up an account.
• Pros: Aliases and attachment downloads. An address can be chosen rather than defaulted, and received files can be saved before expiry.
• Pros: Multiple paid capacity tiers. The plans increase domain, inbox-record, and saved-message limits, with Diamond offering unlimited quotas.
• Cons: Short and unclear practical retention. Inbox lifespan is given as minutes, while the guide describes deletion usually after 24 hours, making the service unsuitable for keeping messages.
• Cons: No inbox protection. Public temporary addresses should not be used for sensitive or financial matters.
• Cons: API-key access is unfinished. Published documentation does not by itself make the advertised private API access ready to use.

Alternatives

Temporary Email Services is a useful starting point if you want to compare services across the category rather than settle on 1SecMail.

• SecureTempMail is worth considering if you want up to 30-day retention, premium private domains, attachment downloads, inbox history and search, or broader desktop platforms; its Premium plan is $39 a year.
• Temp-Mail.org may suit readers who want an iOS app as well as Android, web, extension, and API access. Its free plan is receive-only and stores messages for up to 1–2 hours.
• 10 Minute Mail is a simpler option if a 10-minute address with a timer that can be reset for another 10 minutes is enough.
• EmailOnDeck is another free option, with an ad-supported plan limited to one email at a time and securely wiped logs.
• EmptyInbox may fit developers who want REST API and MCP access with a free allowance of 5 inbox credits.
• TempMailo is an alternative if saving and restoring an inbox or using Reply Relay with usage limits matters.
• Getnada is another freemium web and API option for readers comparing guest and member access.
• Mail.cx may be a better fit if you want one-hour mail retention, or a paid plan with custom domains and API access.

Verdict

1SecMail is a practical pick for low-stakes disposable email when no-registration access, aliases, and attachment downloads matter. Its free tier makes casual use straightforward, and paid plans raise the storage and domain quotas. Look elsewhere for sensitive mail, dependable retention, or an API integration that is ready to use.
