Frequently Asked Questions

TL;DR

• “Random email addresses” are short-term inboxes for quick sign-ups, testing, and privacy.
• The easiest method is a temp mail generator: you get an inbox instantly, no sign-up, emails auto-delete after ~24h.
• On tmailor.com, you can Reuse Your Temp Mail Address via an access token (while messages still expire on schedule).
• Some websites may block disposable emails; always follow the site’s terms.
• Consider a custom domain on Tmailor for more control over your aliases.

What is a random email address?

A random email address is a temporary, often anonymous inbox created for short-term use (e.g., one-off registrations, downloads, or tests). With temp-mail style services, messages arrive instantly and are automatically deleted after ~24 hours to reduce retention and spam exposure.

Start here: /temp-mail — quick definition + generator page.

When should you use one?

• Signing up for trials, newsletters, or forums you don’t fully trust
• Receiving verification or OTP codes without exposing your real inbox
• QA/testing sign-up flows and email deliverability
• Reducing spam to your primary email

(Avoid for banking, long-term accounts, or anything requiring reliable recovery.)

Three safe ways to generate random email addresses

Method A — Use a Temp Mail Generator (fastest)

1. Visit /temp-mail → a random inbox is created instantly.
2. Copy the address and use it anywhere you need an email.
3. Read messages in the browser; messages auto-delete after ~24h.
4. Save the access token to return to the same address later.

Why this works well on Tmailor

• Hosted on Google’s global server network for speed/reliability.
• Reuse Your Temp Mail Address via access token across sessions/devices.
• Receive-only by design (no sending / no attachments) to limit abuse.

Method B — Gmail “plus addressing” (for filtering)

Add a tag after your username, e.g., name+shop@…; emails still land in your real inbox, letting you filter by tag. Use this when you want tracking/filters but not full anonymity. (General technique reference: sub-addressing).

Method C — Your own domain for temp aliases

Point your domain to Tmailor’s temp mail and create on-brand, disposable aliases you control; still benefit from access-token reuse and central management. Start by introducing Tmailor’s Custom Domain Temp Email Feature (Free).

How to choose a random email generator (checklist)

• Speed & reliability: global infrastructure / fast MX (Tmailor runs on Google’s network).
• Retention policy: clear auto-delete window (~24h).
• Reusability: access-token or equivalent to reopen the same inbox later.
• Domain breadth: diverse domains to reduce false blocks (Tmailor lists 500+).
• Abuse controls: receive-only mode; attachments disabled.

Setup: generate → verify → reuse (step-by-step)

1. Generate at /temp-mail.
2. Verify by sending a test message from another account; read it online instantly.
3. Reuse: save your access token (bookmark the page or store the token); reopen the same inbox later via /reuse-temp-mail-address. (Emails still expire on schedule.)

Limits & compliance (what to expect)

• Service blocks: Some platforms block disposable addresses to reduce spam or enforce KYC; this is common and documented.
• Receive-only: No sending/outgoing mail and no attachments on Tmailor; plan your workflow accordingly.
• Data lifecycle: Emails are auto-deleted after ~24 hours; copy anything important before expiry.

Random vs Temp Mail vs 10-Minute Mail vs Burner/Fake Email

• Random email address: any generated address, usually short-term.
• Temp mail: a disposable inbox you can receive immediately; on Tmailor, reuse via token is supported.
• 10-minute mail: strictly time-boxed inbox (good for one-shot verifications).
• Burner / fake email: colloquial terms overlapping with temp mail; intent is privacy and spam control.
