Second only to Apple, Gmail is by far one of the most popular email clients. As of January 2023, Gmail’s market share was 28.04% with the third most popular client lagging behind at just 4.45%. Why is it so widely used?
A key contributor is Gmail’s inclusion in the larger Google Workspace ecosystem of tools. But another factor is that there are hundreds of extensions available that expand the possibilities of what you can do within Gmail. Want to see some of our favorite extensions for writing, productivity, and more?
5 Gmail extensions that can enhance your writing process
Let’s start with extensions that can speed up or otherwise enhance your writing process.
The Jasper Chrome extension—our AI-powered writing assistant—works wonders in Gmail. Via templates, commands, or a mix of the two, you can write effective emails up to 10 times faster. Whether you correspond with clients or team members, send cold emails, or use Gmail to distribute marketing emails, Jasper can help.
For example, here’s a short cold email generated using the Personalized Cold Email and Email Subject Lines templates.
To generate the subject line, I input a fictional product name, a tone of voice, and a short sentence on the email topic. Jasper suggested several options, from which I picked the one you see above.
To generate the email, I entered some info about the product and the idea I wanted to pitch, along with an interesting fact about the recipient. Jasper gave me three cold email options to choose from.
Of course, I’d want to make some edits, like replacing “FIRST_NAME” with Austin’s name or listing some specific benefits of the proposed partnership. (The same would be true of any content generated with the help of artificial intelligence.) But Jasper provides a solid foundation to build from. And the better your prompts, the better he writes!
Templates: Use popular copywriting frameworks like AIDA, or other templates like Content Improver to write more effective emails.
Commands: Give Jasper instructions on what to write and how.
Languages: Let Jasper help you write in any of the 29+ available languages.
Jasper considers the context of an email thread to help you write more relevant replies faster.
Access Jasper within Gmail instead of having to copy and paste between the two.
The Jasper extension doesn’t just work in Gmail; you can also use it in Google Docs, WordPress, Webflow, and just about anywhere else you write online.
Jasper is a paid tool.
You can’t access history within the extension so if you’d like to reference the output from a previous generation, you’ll have to go to the web app.
Discoverly gives a bird’s eye view of the work info, social profiles, and mutual connections of people who email you. It can come in handy when, for example, you need to verify the credibility of subject matter experts who respond to your queries on sites like Help a Reporter Out.
Work info: See a sender’s company and role.
Connections: Learn what connections you share across LinkedIn, Facebook, and Twitter.
Recent tweets: Check out the kind of content a person posts.
Discoverly minimizes the manual work of finding social media profiles (and online profiles in general) for contacts you’re not familiar with.
You can invite friends to earn yourself access to more information about your contacts in Gmail.
As of now, you can’t see mutual connections for other platforms like Instagram.
The website, onboarding flow, and user interface copy could be more informative to reduce friction.
Pricing: Discoverly has a free plan. However, you can pay $5 for some additional features like email search.
Streak CRM for Gmail
Streak’s Gmail extension is a great place to store contact info and notes on project stakeholders and content contributors. It’s also great if, for instance, you’re a freelance copywriter and need a simple and free CRM for managing customer relationships.

Snippets: Save reusable message drafts for later use.
Mail merge: Send personalized emails in bulk (e.g. notifying experts that content they’ve contributed to has gone live).
Keep lists of contacts such as subject experts handy, along with notes and contact info.
Streak has Android and iOS apps and integrates with Zapier and various APIs.
The free plan is often sufficient for solo users, so Streak is great if you’re on a budget.
Some users have had trouble contacting customer support.
Some users have reported a few bugs such as the email tracking feature not working.
Pricing: Streak has a free plan and four paid plans ranging from $19 to $159 per month.

As you consistently implement Just Not Sorry’s recommendations, you’ll be training yourself to naturally communicate more confidently.
Your communications will be more concise, which your recipients will no doubt appreciate.
The Just Not Sorry website features a full list of warning phrases and why you should avoid them, along with links to various additional resources.
Just Not Sorry doesn’t consider the context of the message you’re writing so its warnings aren’t always applicable.
Users wish the extension worked in other text fields and word processors besides Gmail.
Pricing: Just Not Sorry is free.

Subtasks: Summarize conversations into action items.
Due dates: Set deadlines from within any email.
