What it is

1SecMail provides temporary disposable email for sign-ups, with mailbox creation that does not require registration or personal information. Users can send and receive messages, create custom aliases, and receive attachments to download before they expire. Its guide says addresses and related communications are usually erased automatically after 24 hours. The service is available on web and Android, and a Chrome extension provides access to temporary email. Developers can use published API documentation covering domains, mailbox creation and management, message retrieval, and attachment downloads; however, the API-key feature is currently under development. Premium offerings list additional domains, inbox records, saved messages, attachment viewing, and support. The Premium page also advertises 100MB storage and no ads. A free plan is available; Standard costs $4.99 a month, and paid plans start at $4.99 a month. 1SecMail cautions that public temporary addresses are not suitable for sensitive or financial information.

1SecMail in depth

Read the full write-up

1SecMail is a disposable-email service for quick, low-stakes registrations and short-lived message handling. It fits individuals who want an alias without an account and developers assessing disposable-mail workflows. Its convenience is real, but the very short retention and unprotected public inboxes make it unsuitable for anything important.

Overview

You can create a temporary mailbox without registration or personal information, choose a custom alias, and send and receive messages. 1SecMail says it collects no personal information and automatically removes transient mail. That makes it useful for trials, downloads, and other sign-ups where exposing a primary address is undesirable.

Retention requires caution. The service gives an inbox lifespan of minutes, while its one-time-email guide says addresses and related communications are usually erased after 24 hours. In practice, treat every mailbox as expendable and save anything you need immediately. Public temporary addresses have no inbox protection and should not be used for sensitive or financial information.

Key features

No-registration mailboxes: Generate an address instantly, which suits one-off, low-consequence sign-ups but provides no account-based recovery.

Custom aliases: A unique alias is more useful than a generic default when a service requires a distinct address.

Send and receive: Two-way messaging covers more than receive-only disposable services, although short expiry limits ongoing conversations.

Attachments: Incoming files can be downloaded before the email expires, a practical advantage for temporary verification or delivery workflows.

Privacy and limits: Automatic deletion and the stated lack of personal-data collection reduce persistent exposure, but public addresses and the absence of inbox protection limit appropriate use.

API documentation: Published endpoints cover domains, creating, updating and deleting emails, retrieving messages, and downloading attachments. The API-key feature is under development, so documented capability should not be confused with a currently dependable access method.

Premium domains and storage: Premium users can select 1secmail.cc, 1secmail.website, and 1secmail.live, with advertised 100MB storage, no ads, and premium support.

Pricing

The free plan costs 0.00 USD and includes three own domains, three inbox records, three saved messages, premium support, attachment viewing, and premium domains. It is enough for occasional personal use, but the small record and message caps make it a poor fit for repeated or organized workloads.

Standard costs $4.99 a month and raises the allowances to five own domains, 30 inbox records, and 30 saved messages, while retaining support, attachment viewing, and premium domains. It suits regular individual use that outgrows the free caps.

Premium is $9.99 a month, with 10 own domains, 50 inbox records, and 50 saved messages. Choose it when those higher quotas matter; it does not change the fundamental short-lived nature of disposable mail.

Pro API Key costs $10 a month and promises unlimited requests subject to a fair-use policy, faster response times, private API-key access, and developer-oriented access. Because API-key functionality is still under development, this plan is best considered for teams willing to verify readiness before depending on it.

Gold costs $35.99 a year and provides 20 own domains, 500 inbox records, and 500 saved messages, plus the shared support, attachment, and premium-domain features. Diamond costs $45.98 a year and removes those stated quotas with unlimited own domains, inbox records, and saved messages. These annual tiers are the logical choices for sustained, high-volume use; neither makes sensitive use appropriate.

Platforms

1SecMail offers web access, an Android app, an API, and a browser extension. The Chrome Web Store extension is intended to provide immediate access to temporary email. The API documentation is broad, but the API-key feature remains under development, so web, Android, and extension access are the safer assumptions for present use.

Who it's for

Choose 1SecMail for disposable addresses during routine registrations, short trials, or other situations where protecting a primary inbox matters more than keeping mail. Custom aliases and attachment downloads make it more capable than a bare receive-only mailbox. It is not the right choice for banking, account recovery, confidential correspondence, or any workflow that needs a protected or durable inbox.

Pros and cons

Pros

No registration or personal information is required to create a mailbox.

Custom aliases, sending, receiving, and attachment downloads support varied short-term tasks.

Free access is available, with paid tiers offering substantially larger record and message quotas.

Web, Android, and extension access cover common ways to reach a temporary inbox.

Cons

Inbox lifespan is measured in minutes, and the service also describes deletion within about 24 hours, so retention is unreliable for anything ongoing.

Public addresses have no inbox protection and are explicitly unsuitable for sensitive or financial information.

The API-key feature is still under development, weakening the case for production integration.

Free-plan allowances are limited to three own domains, three inbox records, and three saved messages.

Alternatives

Browse the Temporary Email Services list when you want to compare the broader category. Pick SecureTempMail instead if up to 30-day retention, private domains, attachment downloads, and inbox history are more important than 1SecMail's shorter lifecycle. Temp-Mail.org is a better fit for receive-only use with messages stored for up to one to two hours, or for users who need iOS access.

10 Minute Mail suits a narrowly timed address that expires after 10 minutes and can be reset for another 10. Choose EmailOnDeck if one-at-a-time private emails and securely wiped logs match your priorities. Mailinator is the alternative to consider for private inboxes, permanent storage, and stated throughput quotas. EmptyInbox is aimed at users who want inbox credits with REST API and MCP access. TempMailo offers save-and-restore inboxes and reply relay. Getnada is another freemium web/API option with guest and member tiers.

Verdict

1SecMail is a sensible choice for quick, anonymous, low-stakes email, especially when custom aliases or attachment downloads matter. Its free entry point and broad client access are compelling. Look elsewhere for protected inboxes, dependable retention, sensitive accounts, or a production API integration that cannot wait for API-key support to mature.

Verdict

1SecMail covers temporary inboxes, aliases, and attachments, with web, Android, and extension access. Its short retention and warning about public addresses matter when deciding what to use it for.
