TempMailPortal

Overview

TempMailPortal provides temporary, receive-only inboxes for low-stakes sign-ups and testing applications you control. It suits people who want to keep optional registrations away from their main email, but its website inboxes are not safe for sensitive messages. Free access across web and Android makes it a practical disposable mailbox, with important privacy and sending limits.

Key features

You can use the web inbox without signing up, and messages normally expire within 24 hours; they can also be deleted immediately. New random inboxes use private access credentials, so an address alone does not open those inboxes. That is a useful distinction for temporary access, but it does not make the service appropriate for confidential mail: the privacy policy warns that anyone who knows or guesses a temporary address can view its messages.

TempMailPortal receives ordinary text and HTML mail but has no composer, reply function, or outbound email path. That keeps its purpose focused on receiving one-time messages, not managing correspondence. The website displays attachment filenames without opening the files; the Android app can view supported files or save retained attachments, which makes Android the more capable choice when an incoming message includes a file.

The privacy policy says message bodies are not sent to Google AdSense, used to build advertising profiles, or sold. Those practices are reassuring, but they do not override the address-access limitation. The service also prohibits fraud, impersonation, ban evasion, spam, mass registrations, and accounts users lack permission to create.

Pricing

Free — free. The plan includes web and Android inbox access, with messages expiring within up to 24 hours. There is no free trial because the service is free; no paid plan is described. For occasional disposable mail, the lack of a subscription makes the offer straightforward. Android users should account for the app’s different guest and signed-in allowances.

Android guest allowances are one active inbox, three new inboxes, 300 mail API requests per day, 10 MiB of attachment transfers, and 30 incoming messages per day. Signed-in allowances rise to five active inboxes, 20 new inboxes per day, 1,000 requests per day, 50 MiB of attachment transfers per day, and 100 incoming messages per day. These caps may constrain repeated testing or heavier attachment use, even though the basic inbox service is free.

Platforms

TempMailPortal is available on the web and Android. The web option is useful for quick, no-account access, while Android adds supported attachment viewing and saving. The Android allowances apply to its inbox use. Public developer API access is being retired, so old curl examples and API keys are not a supported integration route; developers should not choose it for a new API-dependent workflow.

Who it's for

This is best for people who need a short-lived address for permitted, low-risk optional sign-ups, or developers testing their own applications without using a personal inbox. It is a poor fit for sensitive accounts, private correspondence, or any situation where a message must be sent or answered. The limits on abuse also rule out using it to evade service rules or create accounts without permission.

Pros and cons

• Pro: Free web and Android access without a web sign-up makes one-off receiving convenient.
• Pro: Automatic expiry within up to 24 hours and immediate deletion suit temporary use and reduce how long messages remain available.
• Pro: Android supports viewing supported attachments and saving retained files, beyond the website’s filename-only display.
• Con: Website inboxes are not password-protected; a known or guessed address can expose its mail, so sensitive messages belong elsewhere.
• Con: Receive-only operation rules out replies, and retiring public API access makes it unsuitable for new API integrations.
• Con: Android guest quotas are modest for sustained use, including 30 incoming messages per day and one active inbox.

Alternatives

EmailOnDeck is worth considering if you want a free, ad-supported option with one email at a time and private emails. SecureTempMail is a better direction if you need a paid premium option with up to 30-day retention, private domains, attachment downloads, and inbox history and search; its premium plan is $39 a year.

Temp-Mail.org offers a free receive-only plan with messages stored up to 1–2 hours, so consider it if shorter retention suits your use. 10 Minute Temp Email is a web-only alternative with a 10-minute mailbox and no recovery. 1secemail is another free web-based temporary email service.

Emailnator may suit users who want up to 100 addresses at once, with public inboxes and deletion after 24 hours on its free tier. Maildrop is a free disposable inbox with a maximum of 10 messages and a 500k message-size limit. MailDrop offers a free tier capped at 300 requests per day and one mailbox per 24 hours, or a Starter plan at $5 a month for 30,000 requests per month and 10 mailboxes per 24 hours.

Verdict

Choose TempMailPortal for free, short-lived receiving on web or Android, especially for permitted optional sign-ups and testing your own applications. Its clean receive-only purpose and quick expiry fit that narrow job well. Look elsewhere for sensitive mail, sending or replying, or a supported API integration.
