Blog / Business / 8 Best AI Email Assistants: Ignite Your Productivity (2024)

Email and productivity often seem to be at odds with each other. This is true whether you’re trying to wrangle a personal inbox that always seems to be full or trying to send email more efficiently for business purposes. Lucky for all of us, AI email assistants are making our lives easier and more productive.

This article covers some of the best AI email assistants that solve all kinds of productivity woes.

How Can an AI Email Assistant Help?

Artificial Intelligence (AI) has recently made a significant breakthrough in digital technology, allowing an average person to perform monumental tasks that would typically require an extensive amount of knowledge and experience.

With the powerful AI tools now at our fingertips, mundane tasks like writing emails and managing inboxes have become much easier. No one particularly enjoys managing their email tasks, especially when it has to do with work. This is exactly where AI is great for helping as an email assistant.

Here are some of the things that AI is solving for heavy email users and marketers:

  1. Inbox management (declutter, prioritize, and remind)
  2. Email drafting for marketers, professionals, and B2B cold emailers
  3. Automating routine tasks for greater efficiency
  4. Personalizing email at scale for 10x outreach

All the tools in this article use AI to accomplish at least one of these things. Some do two or three of these, depending on your use case. Any way you cut it, these tools will help you save a tremendous amount of time and allow you to focus on the most productive parts of your day.
