Embed a disposable email widget

Give your visitors an instant temporary email address, embedded directly in your site. Free, no signup, GDPR compliant.

Why install this widget on your site?
1.
Your visitors stay on your site
Guides like 'how to create an X account' lose 60% of readers at the sign-up step. With an embedded widget, they stay.
2.
Useful tool = longer session time
Visitors linger on pages that are genuinely useful. Google reads this as a quality signal and rewards your ranking.
3.
$0, no sign-up, no maintenance
One line of code to paste. No API key, no quota, no updates. The widget evolves automatically without you touching anything.
4.
GDPR-friendly, no cookies
No third-party cookies, no trackers, no personal data exposed. Compatible with the strictest privacy policies.
Integrate in 30 seconds

Pick the method that fits your site. Simplest first.

Why embed our widget?
Free. Always. Unconditionally.
No registration, no API key, no rate limits. Copy the code, paste it into your page. That's it.
A discreet brand mention included
Each widget displays a discreet attribution to mail123.click. By offering this useful tool to your readers, you enrich your page and increase their time on site without any external redirect.
GDPR compliant — no visitor data collected
The widget includes a mini mailbox: your visitors see emails arriving in real time, read content and copy OTP codes — without leaving your site.
