In fact, over 3 million emails are sent every second, research shows.

In this article, we'll list out the 10 best free AI email generators and writers for responses in 2025. Let's dive in!

What Are AI Email Generators?

AI email writers and generators are tools that help you write emails using artificial intelligence. You give the tool a short prompt or a few key points, and it generates a full email for you.

Here are a few things they can help you write:

• Emails and responses to them
• Professional messages
• Signatures, openings, and closings
• etc

Most email writers are designed to sound natural and professional while saving you time. Many also include templates or tone controls so you can adjust how the email sounds.

Why Use AI Email Generators?

If you’re tired of spending too much time on email, these tools can help you respond faster and with less effort. They’re built for everyday tasks like replies, follow-ups, outreach, and internal updates.

Here are the benefits of using an AI email generator:

• Save time on repetitive messages - Quickly draft emails you send often, like follow-ups or meeting requests.

How to Choose an AI Email Generator

There are a lot of tools out there, but not all of them are built for the kinds of emails you write every day. Whether you're replying to messages, writing outreach, or handling follow-ups, it's important to pick a tool that fits your workflow.

Here are some things to look for when choosing an AI email generator:

• Works where you write - Choose a tool that integrates with Gmail, Outlook, or your browser so you don't have to switch tabs.

• Supports replies and new emails - Make sure it can handle both writing from scratch and responding to incoming messages.

• Lets you adjust tone and length - Look for tools that let you sound friendly, formal, or concise depending on the situation.
