Best 8 AI Email Tools in 2024

Updated: Jan 22

Bunny Searching for the Best AI Email Tools

The Email interface and tools that you use can make a big difference in your level of productivity. In fact - saving just 20% of the time you spend on your emails will save the average office worker 3.38 work weeks per year. Even 2% makes a difference! The below highly-rated tools are curated to help you find your match.

How to select the best AI Email Tool

Choosing your productivity tools and interfaces seems simple - but implementing the wrong system will cost you lots of time in the long run in learning and implementation. As you decide which tool to try out, consider these four criteria: 

  • Breadth of Features. Look for tools that offer a comprehensive range of capabilities, such as email composition, summarization, and customization. The more features a tool has, the better it can adapt to your specific needs.

  • Pricing. Consider the cost-effectiveness of the tool. Does it offer a free trial or a free version? What are the pricing plans for premium features? How will it price into the future?

  • Workflow. Does this change my current workflow? Will I need to change my habits to use this? Some tools are so simple to use, that you intuitively know how to use them and barely notice their existence. Others are more cumbersome, but may have more features and customizability.

  • Saved Time. Envision yourself using this tool? Will it actually save time with your work flow?

  • Who's this for? Determine who the tool is best suited for. Is it designed for individual users, freelancers, small businesses, or large enterprises? Understanding the target audience of the developers not only tells you whether the tool may be a fit for you now, but it can clue you into what their development goals may be in the future. It's best to get integrated and used to a service that will grow with you, rather than developing in a different direction.
