30 essential email extensions and add-ons that will make your life simpler

Email is a valuable business communication tool that is quick, inexpensive, and accessible. Email may be highly beneficial to organizations since it efficiently and effectively transmits many types of electronic data.

One of the most valuable features of email is the ability to send electronic files such as written documents, photographs, and data sheets to several recipients at once, simply attaching the file to an email.

However, emailing apps are usually plain and simple. And most of the time, we need email extensions and add-ons to use their unique features that will ease our emailing. 

What are email extensions and add-ons?

Email add-ons and extensions are utilities that can be added to the Gmail app or any other email software. These add-ons enhance Gmail’s functioning by giving users more options. 

Add-ons are installed in the G-Suite, while email extensions are installed in the internet browser.

Are email extensions secure?

Email add-ons are accessible from the main menu of any document you’re working on, where you may explore and install them. Users may be misled into a false feeling of security by the ease with which these add-ons can be installed and appear approved by Google.

That isn’t to say that all extensions are dangerous, but it does suggest that you should be cautious while installing them. Nonetheless, third-party add-ons can expose your business to new security threats.
