6. Zoom for Gmail

It’s possible to use Zoom from within Gmail thanks to the Zoom for Gmail extension. Video conferencing has become a little more convenient as a result. Using this extension, you can check your call, meeting, and conference schedule and start video calls directly from Gmail. As a whole, it makes it easier to track all your communication channels in one place.

7. Slack for Gmail

Slack for Gmail enables you to keep all your communication in one place. With Slack being used by many businesses, it can be inconvenient to alternate between the two. Slack is excellent for internal communication, but email is still a viable option for communicating with clients and vendors. Slack for Gmail lets you submit messages to Slack channels directly from Gmail, saving you time and making your workflow more efficient.

8. DocuSign for Gmail

Sending and receiving documents for signatures can be time-consuming. If you work in a profession that involves a lot of paperwork, like law or consulting, you’re probably used to signing documents regularly. Using DocuSign for Gmail, you may email legally-binding documents directly from your Gmail inbox. The signatures are legally binding, and all of the data is encrypted. You can also send reminders without having to open the complete DocuSign application.

9. Trello for Gmail

If you use Trello for project management, this add-on is a great benefit. Trello for Gmail allows you to add new cards from your inbox instead of opening up Trello. You can get an email about a new project and add a card in seconds. There’s no need to switch tabs.

10. Dropbox for Gmail

For Gmail users, Dropbox for Gmail makes it easy to share files over email. You can use this extension to instantly share a file you’ve posted to Dropbox’s cloud storage. Preview files and search for them before sending them using Dropbox’s link. Sending large files is made much easier by this method. In addition, you can use Dropbox for Gmail to save new files directly to Dropbox without first downloading them.

Summary

But don’t get carried away. Extensions that don’t play well with each other can slow down your browser. It’s essential to keep things simple. Get rid of extensions you don’t use regularly, and choose the ones you do.
