Sometimes after you send an email, panic sets in:
"Did I sound too mean?""Should I have added that document?"
Pluto mail is a new service that hopes to fix these stressful situations.
The free program syncs with your inbox and lets you accomplish four specific tasks: set expiration timers on messages, unsend emails, add read receipts and edit sent messages before someone else opens them.
Pluto is still in beta but we were able to try out.
Go to Pluto's website. Click Sign Up in the upper-right corner. Pluto can sync with Gmail, Yahoo, iCloud and other email accounts.
Enter your email address. You'll be placed on a waiting list.
After a day, this verification message should pop up in your inbox. Click Sign Up at the top.
