What is an AI email writer?

An AI email writing tool uses artificial intelligence to help you compose, edit, and optimize emails. 

AI writers are backed by natural language processing (NLP) and machine learning technologies. These help them understand context, suggest relevant content, and improve the overall quality of your emails.

You can use an AI email writer to correct grammar and style, get suggestions to clarify your messages, and even generate complete email drafts from brief inputs. 

Benefits of using AI email writing tools

There are three main benefits of using AI email writing tools:

Saves you time

An AI email writer is like a super-fast assistant who knows exactly what to say, cutting down the time you spend composing emails. Take Writesonic, for instance—it can produce 1,500 words within seconds. A study also found that people who use tools like ChatGPT spend about 40% less time writing content​.

This means a task that previously took you four hours to complete will now only take 2.6 hours with an AI writer by your side.

Boosts productivity

AI tools aren’t just about saving time—they also boost productivity. An MIT study found that using AI tools cuts down the time it takes to finish writing tasks by around 11 minutes and improves the quality by 18%. 

With better email quality and more time on your hands, you can focus on more meaningful tasks and stay more productive throughout the day.

Improves the quality of emails

Not everyone is a natural-born writer (and even the best writers can use some help). AI email assistants improve writing quality by providing grammar checks, style suggestions, and tone adjustments.

One survey found that participants experienced up to a 74% reduction in writing errors when using their platform. This increased accuracy ensures your emails are more professional, clear, and effective.
