What is an AI Email Writer?

An AI email writer is any tool that lets you generate email content using artificial intelligence. These tools streamline the email writing process, making it easier to craft engaging messages for customers, leads, and contacts. Some tools, like MailerLite, are full-fledged marketing platforms. Others, like Grammarly and ChatGPT, focus on writing assistance. Choosing the right one depends on your workflow and what other features you need.

How We Chose the Best Tools

We picked a mix of tools: some we already use and trust (like MailerLite, Grammarly, and ChatGPT) and others that came highly recommended. Each tool was tested to evaluate how well it fits into email creation workflows. Most use large language models, so output quality is similar, but UI, pricing, and bonus features differ greatly.
