Safer Send Button is a free Chrome extension developed by avner.dev that aims to make the Gmail send button safer and reduce accidental sends and data leakage. This add-on is designed to provide users with a helpful alert system when drafting emails in Gmail for Business.

One of the common mistakes that users make is unknowingly sending an email outside of their domain or organization. Gmail only provides a warning if the recipient is not already in the user's contacts, which can easily be overlooked. Safer Send Button helps address this issue by alerting the sender if they are about to send an email outside of their intended domain.

Another common mistake is mixing up emails to multiple contacts from multiple companies, leading to embarrassing situations. With Safer Send Button, users can avoid the "Oops, I cc'd the wrong Tony" scenario by providing a clear indication when they are about to send an email to the wrong recipient.

With Safer Send Button, users can have peace of mind knowing that they have an extra layer of protection against accidental sends and data leakage in Gmail. This simple yet effective Chrome extension is a must-have for anyone who wants to improve their email sending experience.
