Three Steps to Save Your Emails

Set it up once, and it quietly works in the background every time you compose an email.

1

Install the Extension

Add Attachment Reminder to Chrome with one click. No sign-up required for the free plan.

2

Write Your Email

Compose your email normally in Gmail, Outlook, or Yahoo Mail. The extension monitors in the background.

3

Get Alerted Instantly

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

💡 Important Tip
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.
