5. Ellie

Best for: Writing replies that reflect an existing email thread.

Ellie uses connected email threads and your writing style to draft replies for Gmail and Outlook. It can draw on the conversation you’re answering instead of starting without context. Drafts stay in your inbox for review, so you can check the wording and make sure the reply fits the thread.

6. Mail Magic AI

Best for: Replies informed by previous emails.

Saymail is a Chrome extension that helps Gmail users write emails with AI. Its focus on Gmail and Chrome makes it a straightforward browser-based option if Gmail is where you do most of your work. If you use a different email platform or browser, check compatibility first.

An AI email writer can create a message from a prompt, draft a reply, or rewrite existing text for clarity, length, or tone. Some tools also generate marketing copy. Others use email threads to help shape replies.

Marketing-focused software, such as Constant Contact, generates campaign content from prompts and may offer multiple versions.
