TempMailer vs Guerrilla Mail

The key difference: persistence

Guerrilla Mail is one of the oldest disposable email services, established in 2006. It lets you send as well as receive emails, choose custom inbox names, and handle attachments. The tradeoff: 60-minute expiry, public inboxes (anyone with your address can read your emails), and a dated UI. TempMailer solves the expiry problem. When you generate an address on TempMailer, it's saved to your browser. You can return to it days, weeks, or months later. The inbox waits for you - no timer, no pressure.

When to use Guerrilla Mail

Guerrilla Mail is better when:

• You need to send emails (not just receive)
• You want to choose a custom inbox name
• You need attachment support up to 150MB
• You're okay with 60-minute sessions

When to use TempMailer

TempMailer is the better choice when:

• You're signing up for accounts you'll need to access later
• You want a private inbox (not publicly readable)
• You need a persistent address for developer testing
• You've lost account access because a temp email expired before
• You want an ad-free experience
