Frequently Asked Questions
Everything you need to know about TempMailKit, how it works, privacy, security, technical details, and how to get the most out of your temporary inbox.
General
What is TempMailKit?
TempMailKit is a free temp email and temp mail service that generates a disposable inbox for you instantly, no account, no password, no personal information required. You get a unique @tempmailkit.com address that works like a real email address but expires after 10 minutes, taking all its messages with it.
Is TempMailKit a temp Gmail or Google temp mail?
No. TempMailKit is not affiliated with Google, Gmail, or Google Mail. Many people type "temp gmail", "temp mail gmail", "gmail temp mail", or "google temp mail" into search when what they really want is a free, throwaway inbox that works as smoothly as Gmail but without a Google account, a phone number, or a password. TempMailKit is exactly that alternative: an instant disposable address with zero sign-up. If you specifically need a Google Mail mailbox, you have to create one directly with Google, which generally requires a working phone number.
Can I receive Gmail and Google emails on a temp mail address?
Yes. Any email sent from Gmail, Google, or any other provider, including verification links and one-time codes, lands in your TempMailKit inbox just like it would in a normal mailbox. The catch is the other direction: creating a brand-new Gmail or Google Mail account usually requires phone verification, so a temp email is best for receiving messages and verifying third-party sites rather than registering a fresh Google mailbox.
Is TempMailKit free to use?
Yes, completely free. We are supported by display advertising. You may see ads on the page, but they have no effect on the functionality of your temporary inbox. We do not charge for any feature described on this site and we do not sell user data.
Do I need to create an account?
No. That is the whole point. Open TempMailKit and your inbox is ready immediately. There is no sign-up form, no password, no email verification, none of the friction that disposable email is designed to help you avoid.
What can I use a temporary email address for?
You can use a disposable email address anywhere a real email address is accepted. Common uses include registering on websites you do not fully trust, signing up for free trials, downloading gated content, verifying forum accounts, testing software and APIs during development, and any other situation where you need to confirm an email address but do not want to use your personal one.
Is TempMailKit legal to use?
Yes. Using a disposable email address is completely legal in all major jurisdictions. It is a privacy tool, similar in principle to using a P.O. box instead of your home address. Like any tool, it should be used responsibly, using it to commit fraud, harass others, or circumvent legitimate security measures violates our Terms of Service and may be illegal. Used appropriately, it is simply a way to manage your inbox and protect your privacy.
What makes TempMailKit different from other disposable email services?
TempMailKit is built with a modern, fast infrastructure: email is routed through Cloudflare's global network and stored in a low-latency edge database (Upstash Redis), so messages typically arrive within 5–15 seconds. The interface is designed to be clean and distraction-free with no forced sign-ups, no dark patterns, and no nagging popups. We are also transparent about how the service is funded (display advertising) and about the minimal data we collect.
How It Works
How quickly do emails arrive?
Emails typically appear in your TempMailKit inbox within 5–30 seconds of being sent. The inbox page checks for new messages every eight seconds automatically. If you are expecting an email and it has not arrived after two minutes, try clicking the refresh button manually. Some services have built-in delays before sending verification emails.
How long does my temporary inbox last?
Your inbox is active for 10 minutes from the moment it is created. A countdown timer in the inbox panel shows exactly how much time remains. When the inbox expires, it and all of its messages are permanently deleted. You can generate a new inbox at any time by clicking the "New Address" button.
Can I choose my own email address?
The free tier generates a random address automatically. Custom addresses on our domain are not currently supported in the free plan. If you need a custom or persistent address, consider using a dedicated privacy email service such as SimpleLogin or AnonAddy, which are designed for long-term use.
Can I send emails from my TempMailKit address?
No. TempMailKit is a receive-only service. You can read emails that arrive at your temporary address, but you cannot compose or reply to messages from it. If you need to send as an anonymous address, a service like ProtonMail offers anonymous account creation.
Can I receive attachments?
Yes, email attachments can be received and will appear within the message view. However, we strongly recommend caution with attachments from unknown senders. We process messages for display purposes, but we cannot guarantee that all attachments are safe. Do not open executable files or Office documents with macros from untrusted senders.
Does TempMailKit work with all websites?
Most websites accept any valid email address format and TempMailKit addresses are indistinguishable from regular email addresses at the protocol level. However, some websites actively block known disposable email domains as part of their registration policy. If a site rejects your TempMailKit address, that site has specifically chosen to block disposable email services. We cannot circumvent those restrictions.
What happens if I close the browser tab?
Your session and inbox address are stored in your browser's session storage, which is cleared when you close the tab. If you close the tab and reopen TempMailKit, you will get a new random address. The old inbox and its messages are irretrievably gone, by design. This ensures there is no lingering record of your temporary activity.
Can I extend my inbox beyond 10 minutes?
Currently, all inboxes have a fixed 10-minute lifetime and cannot be extended. When the timer runs out, you can immediately generate a new inbox with a fresh address. We chose 10 minutes as a balance between being long enough to receive a verification email and short enough that the data is genuinely ephemeral. Extended inbox durations may be considered in a future premium plan.
Is there a limit on the number of emails I can receive?
There is no hard limit on the number of emails you can receive during your 10-minute session. In practice, you are unlikely to hit any infrastructure limit within that window. Very large attachments or unusually high volumes from a single sender may be filtered for abuse prevention purposes.
Do you offer a temp number for SMS as well as temp mail?
A temp number feature, disposable virtual phone numbers for receiving SMS and OTP codes, is currently in limited beta with numbers from the US, Canada, and Israel. The temporary email service is fully available today. You can try the beta on the Temp Phone page; the same privacy-first, no-sign-up approach applies to numbers, though as a shared, receive-only beta it is best kept to casual, non-sensitive verifications.
Privacy & Security
What data does TempMailKit collect?
We collect the minimum data necessary to operate the service. This includes server access logs (IP address, timestamp, requested URL) retained for up to 30 days for security purposes, and aggregated, anonymised analytics about how pages are used. We do not collect your name, permanent email address, or any other personal information. Email content is stored only for the duration of your 10-minute session and then deleted. See our Privacy Policy for full details.
Can TempMailKit read my emails?
Technically, email passes through our mail server before being delivered to your inbox, this is how all email works. Every intermediary in the delivery chain can read the message. In practice, we do not read, scan, or analyze the content of messages for any purpose beyond what is needed to display them. Message content is stored only for the duration of your session and automatically deleted when your inbox expires or you close your browser.
Is TempMailKit GDPR compliant?
Yes. We do not require any personal data to use the service. Any data that is incidentally collected (such as server logs containing IP addresses) is handled in accordance with the GDPR, retained for the minimum necessary period (30 days for server logs), and never sold to third parties. EEA users have the full rights described in our Privacy Policy, including access, erasure, portability, and the right to object. Contact tempmailkit@gmail.com to exercise any GDPR rights.
Are my emails encrypted?
Messages are transmitted over encrypted connections (TLS) between mail servers and between our servers and your browser. Messages at rest are stored temporarily in encrypted databases and deleted automatically. We do not offer end-to-end encryption, no standard email service does unless both parties use a tool like PGP/GPG. For messages that require end-to-end encryption, use a service like Proton Mail with PGP support.
Can someone else access my inbox if they know my address?
Yes. A temporary email address is like a physical mailbox without a lock, anyone who knows the address can send mail to it, and in principle, anyone who navigates to that address on TempMailKit could read messages in it. In practice, our addresses are long random strings that are effectively unguessable. However, you should treat your TempMailKit address as semi-public and never use it to receive sensitive personal or financial information.
Does TempMailKit use Google Analytics or other tracking?
No. We do not use Google Analytics. We use privacy-preserving, aggregated analytics that do not track individual users across sessions or across the web. We do use Google AdSense for advertising, which may set cookies for ad personalisation and measurement. You can opt out of personalised Google ads via Google's Ad Settings page. See our Privacy Policy for full details on cookies and advertising.
What happens to my data if TempMailKit shuts down?
Because we collect minimal data and email content is automatically deleted after 10 minutes, there is very little data to handle in a shutdown scenario. Server logs would be deleted as part of infrastructure decommissioning. If we ever decide to shut down the service, we will post notice on the website at least 30 days in advance.
Technical
Is there an API for developers?
A developer API is planned and currently in development. The API will allow programmatic creation of temporary inboxes, retrieval of messages, and webhook delivery of incoming emails, making it ideal for automated testing pipelines and CI/CD workflows. Check the blog or contact us for updates on the launch timeline.
Can I use TempMailKit for software testing?
Yes, and this is one of its strongest use cases. QA engineers and developers use disposable email services to test registration flows, email notification systems, OTP delivery, and password reset workflows without polluting real inboxes or requiring shared test accounts. The inbox works exactly like a real email address, so it integrates cleanly into automated test suites with tools like Playwright, Cypress, or Selenium.
Why was my email address rejected by a website?
Some websites maintain blocklists of known disposable email domains and refuse to accept addresses from them. This is a deliberate policy choice by those websites, typically to prevent fake account creation or to ensure users have a long-term contact address. If you encounter this, the options are to use a different service with a less-known domain, use a premium email alias service (like SimpleLogin), or use your real email address with that particular site.
What technology powers TempMailKit?
TempMailKit is built on Next.js 14 (App Router) deployed on Vercel. Incoming email is handled by Cloudflare Email Routing, which delivers messages to a Cloudflare Worker. The worker parses and stores the email content in Upstash Redis with a 10-minute TTL. The frontend polls a Next.js Edge API route every 8 seconds to check for new messages, which are then rendered in the inbox UI. The full stack is serverless and globally distributed.
Does TempMailKit support HTML emails?
Yes. TempMailKit renders HTML emails in the inbox viewer, so formatted emails with images, buttons, and styled content display correctly. Plain-text fallbacks are also supported. Remote images in HTML emails are loaded from the sender's servers, which means the sender can detect that the email was opened (this is a standard feature of HTML email tracking and is not unique to TempMailKit).
What browsers are supported?
TempMailKit works in all modern browsers including Chrome, Firefox, Safari, Edge, and their mobile equivalents. The inbox polling and session storage features rely on standard web APIs available in all evergreen browsers. We do not support Internet Explorer. JavaScript must be enabled for the inbox to work.
Billing & Business
How does TempMailKit make money?
TempMailKit is entirely funded by display advertising via Google AdSense. When you visit the site, you may see ads in designated areas of the page. Ad revenue pays for the servers, bandwidth, domain names, and the team that maintains the service. We do not sell user data, offer paid subscriptions (currently), or use other monetisation methods. If you use an ad blocker, the service still works, we just appreciate it if you consider whitelisting us.
Is there a premium version or paid plan?
Not yet. TempMailKit is currently free for all users. We are exploring a premium tier that would offer features like extended inbox duration, custom address prefixes, and API access. If premium plans are introduced, the free tier will remain available. We will announce any changes through the blog and the website.
Can I partner with or advertise on TempMailKit?
For advertising enquiries, our inventory is currently managed through Google AdSense. For direct partnership or sponsorship proposals, please use the contact form or email tempmailkit@gmail.com with a description of what you have in mind. We are open to relevant partnerships that align with our audience and values.
Security & Best Practices
Is it safe to use a temporary email for financial services?
No. You should never use a temporary email address for banks, credit cards, investment accounts, crypto wallets, or any financial service. These accounts send critical security alerts, two-factor authentication codes, transaction notifications, and fraud warnings to your email address. If your temp mail inbox expires, you lose access to those alerts and cannot recover the account via email. Always use a real, permanent email address with two-factor authentication for financial accounts.
What should I do if I think my real email account has been compromised?
Act immediately and in this order: (1) Go directly to the mail provider's website (not via any link in your inbox) and change your password to a new, strong, unique one. (2) Enable or verify that two-factor authentication is active. (3) Check your account's forwarding settings and inbox rules for anything you did not set up — attackers routinely create silent forwarding rules to continue reading your email even after a password change. (4) Check recent login activity for sessions you do not recognise and log out all other sessions. (5) Review your most sensitive linked accounts (banking, shopping) for any unauthorised activity.
Can I check if my email address has been in a data breach?
Yes. Have I Been Pwned (haveibeenpwned.com) is the most widely used and reliable service for checking whether your email address appears in publicly known breach dumps. It is free, does not require registration, and covers hundreds of major breaches. If your address appears, it means the combination of your email and (usually) a hashed or plaintext password from that service is in the hands of whoever bought or downloaded the breach data. Change the password on the breached service immediately, and change it anywhere you used the same password.
How do I protect myself from email phishing attacks?
The most reliable protections are: (1) Never click links in emails to log in to an account — type the URL directly or use a saved bookmark instead. (2) Check the sender's actual email domain, not just their display name — phishing emails often use a real company name but a fake domain like support@amaz0n-helpdesk.com instead of amazon.com. (3) Look at the Authentication-Results in the email headers; a legitimate bank email will show SPF pass, DKIM pass, and DMARC pass. (4) When in doubt, contact the organisation through their official website or phone number, not through any contact information in the suspicious email. (5) Enable two-factor authentication on every important account so that a stolen password alone cannot unlock it.
What is a subscription bomb and what do I do if it happens to me?
A subscription bomb is when an attacker signs your real email address up to hundreds or thousands of mailing lists simultaneously, flooding your inbox with legitimate-looking confirmation emails in minutes. The flood is almost always cover for a separate attack — typically the attacker has accessed one of your accounts and wants to bury the notification email before you see it. If your inbox is suddenly flooded: (1) Do not spend time reading confirmation emails. Instead, go directly to your bank, payment services, and primary email account and check for any activity you did not initiate. (2) Change passwords and check for unauthorised forwarding rules on any account that shows suspicious activity. (3) Use inbox filters to bulk-archive or delete the flood by filtering on "confirm", "subscribe", or "verify" in the subject line.
How do I stop a specific sender from reaching my inbox permanently?
You have several escalating options. First, use your mail client's built-in unsubscribe feature (the "Unsubscribe" button at the top of messages in Gmail and Apple Mail) — this uses a server-to-server mechanism and is safer than clicking a link inside the email. Second, create a filter that automatically deletes or archives messages from that sender's domain. Third, for senders that are violating anti-spam law by not honouring opt-out requests, you can report them to the FTC (US), ICO (UK), or the relevant data protection authority in your jurisdiction. Going forward, using a disposable inbox or alias for new sign-ups means you can cut future senders off cleanly by deleting the alias rather than fighting with opt-out processes.
Should I use the same password for my email as for other accounts?
No. Your email account is the recovery method for almost every other online account you own, which makes it the highest-value target an attacker can compromise. If your email password is the same as your password for a forum, shop, or any other service, and that service is breached, an attacker gets the key to your entire online identity — they can use your email to reset passwords on every other account you have. Use a unique, strong password generated by a password manager for your email account specifically, and enable two-factor authentication on it before any other account. Your email account deserves more security than anything else.
Email Tips
How can I tell if an email is from a legitimate sender or a spammer?
Several signals help distinguish legitimate email from spam or phishing. Legitimate senders typically pass all three email authentication checks — SPF, DKIM, and DMARC — which you can see in the Authentication-Results field if you view the full email headers. The From domain matches the actual organisation (amazon.com, not amaz0n-promo.net). The message has a real physical address in the footer and a working unsubscribe link. The subject line is not excessively urgent, capitalised, or uses unusual characters. The email you received is consistent with your relationship with that sender — you signed up for their list or bought from them. When multiple signals look off simultaneously, treat the message as suspicious.
What is the safest way to unsubscribe from marketing emails?
For email from recognisable, legitimate companies you have dealt with before, clicking unsubscribe is safe and effective. Use your mail client's built-in "Unsubscribe" button (visible in Gmail and Apple Mail at the top of the message) rather than a link inside the email body whenever possible — it uses a secure server-to-server mechanism rather than loading a web page. For email from unknown senders, do not click anything inside the message, including the unsubscribe link — it can confirm to the sender that your address is active, increasing spam volume. Delete without engaging and use your mail client's spam reporting button instead.
What is an email alias and when should I use one instead of temp mail?
An email alias is a permanent forwarding address (like a SimpleLogin or Addy.io address) that routes mail to your real inbox while keeping your actual address hidden. Unlike a disposable inbox, it does not expire. An alias is the right tool when you want ongoing email from a service but not at your real address — you stay reachable indefinitely but can disable the alias if the sender becomes a problem. A disposable temp mail inbox is better for one-time gates: a single confirmation link or verification code after which you have no interest in further communication. The triage rule: will you receive more than one email from this service over time? If yes, use an alias. If you need exactly one confirmation email, use a disposable inbox.
How do email tracking pixels work and can I stop them?
An email tracking pixel is a tiny (often 1×1 pixel) invisible image embedded in an HTML email. When your mail client loads the image, the sender's server records the request and knows that the email was opened, along with your approximate IP address, device type, and the time of opening. Because the image loads from the sender's server — not your mail provider's — your mail client fetching it is the act that triggers the tracking. To prevent this: (1) Disable automatic image loading in your mail client's settings. (2) Use a mail client or extension that proxies remote images (Apple Mail's Mail Privacy Protection does this on iOS and macOS). (3) Use a disposable inbox for email from senders you distrust — when the inbox expires, any pixel loads that do occur cannot be tied to a persistent identity.
What is the difference between spam, phishing, and a scam email?
Spam is unsolicited bulk email sent to many recipients, typically for advertising but without the recipient's permission. It is annoying but usually not immediately dangerous. Phishing is a targeted deception attempt: an email designed to trick you into revealing credentials, personal information, or financial details, usually by impersonating a trusted organisation. Phishing is dangerous because a successful one can compromise accounts and lead to financial loss. A scam email is a broader category covering any email intended to defraud the recipient — advance-fee fraud (Nigerian prince), lottery scams, romance scams, and investment fraud are all email scams. The important distinction: spam is primarily a nuisance, while phishing and scam emails are active threats that require different responses (don't engage, report, delete).
How long does it take for an unsubscribe request to work?
Under the US CAN-SPAM Act, legitimate senders must process opt-out requests within ten business days. Under GDPR in the EU and UK, consent withdrawal must be actioned promptly, typically interpreted as within a few days. In practice, many reputable senders (those using platforms like Mailchimp or HubSpot) process opt-outs within minutes to a day. You may receive one or two more emails during the processing window, which is normal. If you are still receiving mail from the same sender after two weeks, the sender is likely violating applicable law, and you can report them to the FTC (US), ICO (UK), or the relevant data protection regulator.
