Add Self-Destruct (And Many Other) Features to Gmail with mxHero

Gmail is one of the leading email providers in the world, but it doesn’t have all the bells and whistles to make it perfect. Being able to send messages at a later date, send self-destructing messages, tracking attachments and more options would make Gmail the perfect email service. That’s where mxHero Toolbox comes in handy for Gmail users.

‘The mxHero Toolbox extension for Chrome allows users to add all the above features and more to Gmail. It takes all the things that could make Gmail perfect and adds them to a single extension. As long as you use Gmail in your Web browser, you can take advantage of everything mxHero Toolbox has to offer.

What mxHero Toolbox Does for Gmail

The mxHero Toolbox Chrome extension offers the following features to make Gmail more functional.

1. Reply Timeout

Reply Timeout allows you to set reminders to alert you to the fact that certain emails still haven’t been responded to by the recipient. This gives you a way to track whether or not something important has been forgotten or ignored so you can follow-up and get the response you need.

2. Attachment Track

Attachment Track gives you access to real time alerts when an attachment is accessed. This can be a great way to make sure that someone has actually seen what you’ve sent them instead of just telling you that they did.

3. Self Destruct

There are a lot of self-destructing email services available online but no major e-mail provider offers the service themselves. With Self Destruct, you can send self-destructing e-mails through Gmail for added privacy and security without relying on a third party to send them for you.

4. Send Later

Send Later lets you choose exactly when an e-mail is sent so that you can schedule e-mails as necessary during the day.

5. Private Delivery

Private Delivery masks the way you send an e-mail to multiple people by making it appear on their end that you only sent it to them. This can be an easy way to send a mass e-mail without looking like you’re sending a mass e-mail.
