    7 Best Gmail Add-Ons

    Keep in mind that many people use the term add-on and plugin interchangeably, but this is not the case. An extension is installed in your browser, while a Gmail add-on is installed in the G Suite app. G Suite applications are typically more secure than extensions.

    The following list are the best Gmail add-ons that expand the functionality of Gmail and give you easy access to powerful tools that greatly expand your inbox.

    1. Zoom for Gmail

    2020 was the year of the video conference. Between Zoom, Google Meet, and other video conferencing clients, people spent more time communicating through a camera than in face-to-face meetings.

    Zoom for Gmail makes it easy to start a Zoom meeting with anyone you’re emailing. Once installed, you can find Zoom directly on your sidebar. Open an email and then click the Zoom icon to start or schedule a call without opening up another window.

    2. Todoist

    Many people began working from home for the first time this year. In doing so, they discovered the difficulty of managing multiple tasks and keeping track of everything you need to do. Whether you’re a work-from-home beginner or a seasoned pro who wants an easier way to track tasks, Todoist for Gmail can help.  

    After you install the add-on, all you have to do is open an email and click the Todoist logo on the sidebar. If there is a task to be found within the email, Todoist helps you by filling in some of the blanks and allowing you to easily enter the rest of the information.

    You can designate what project the task belongs to, the due date, priority level, and more. Once you have done all of this, just click Add Task to enter it in your to-do list.

    3. Dropbox for Gmail

    When you receive emails with important files, you need to back them up. Dropbox for Gmail makes it easy to do exactly that. Just install the add-on and sign in to your Dropbox account. After this, you can open Dropbox from the sidebar and quickly add any file to your Dropbox storage.

    If there are multiple files within the email, just click the one you want to save and then choose which folder to save it in. Once you have selected the folder and given the file a name, then select Save. Voila—your information is stored within Dropbox without the need to open another window.

    4. HelloSign for Gmail

    5. Slack for Gmail

    Slack is one of the most popular communication platforms on the planet. If you’re ever bored, just look up memes about what happens when Slack goes down. With that in mind, Slack With Gmail can make conversations with coworkers more productive by bringing an email directly into a Slack channel.

    This tool allows you to include attachments and images, too. It’s perfect for those times when an email chain is just a bit too long and unwieldy—just drop it into Slack and discuss it in real-time. You’ll be able to reach a consensus and decide on a solution more easily.
