Well, it was quite simple, I wrote an email, and somewhere in the email I wrote “I attached …” this document. Re-read the email and hit the send button.
And this pop-up came up.
Ouf! Thanks Gmail. How clever. I knew gmail was reading emails content to serve targeted ads, but it also tries help user avoid mistakes. How thoughtful. I feel like I have a safety net.
That’s the coolest gmail feature I have seen since the Unsend option. So simple, yet so useful.
