If you mention an attachment but forget to attach it, a friendly popup stops you right after you hit Send.

Gmail and Outlook have their own built-in attachment reminders that may conflict with this extension — causing double popups or unexpected behavior.

For the best experience, we recommend disabling the built-in reminders in your email settings.

Frequently Asked Questions

Quick answers to common questions about Attachment Reminder.

Attachment Reminder works with Gmail, Microsoft Outlook (web version), and Yahoo Mail. It runs directly in your browser, so there's nothing to configure for each email provider.

No. Attachment Reminder only scans the email you're composing — the one currently being written. It never reads your inbox, sent emails, or any other data. All processing happens locally in your browser. Zero data is sent to any server.

Absolutely! Free users can add up to 10 custom keywords. Premium users get unlimited keywords. You can add words like "resume", "contract", "portfolio" or any term relevant to your work.

Yes! The extension fully supports all languages and alphabets. Whether you email in Spanish, French, German, Japanese, Arabic, or any other language, you can add your own custom keywords and the extension will detect them perfectly.

If you click "Ignore Warning," your email will be sent as-is, without an attachment. The extension respects your decision — it's just there to remind you, not to block you.

Free users get a small, subtle "Powered by Attachment Reminder" signature at the bottom of their emails. Premium users have this removed entirely — your emails stay 100% clean with no trace of the extension.

Yes! You can cancel anytime from your subscription dashboard. There are no contracts or hidden fees. When you cancel, you keep Premium access until the end of your billing period.

When you subscribe to Premium, you get full access to all features for 3 days completely free. You won't be charged anything during the trial period. If you decide it's not for you, simply cancel before the 3 days are up — no charge, no questions asked. If you love it (and we think you will!), your subscription starts automatically after the trial ends.
