Ellie review

Ellie does one thing: write replies. Connect a Gmail or Outlook mailbox on the Business or Professional plan and it drafts responses into your Drafts folder in the background, or trigger it on demand from the browser extension or the Outlook desktop add-in. It replies in any language and copies your tone, and knowledge base training lets you upload PDFs and documents or point it at a website, which helps support and sales inboxes that answer the same questions daily. Roles let one person keep separate tones and knowledge for support, sales or founder email. Casual costs $19 per month for 25 extension-powered replies a day; Business at $39 adds auto-draft, auto-categorise and 3 seats; Professional at $79 removes the daily reply cap and connects up to 3 accounts per user. Ellie does not summarize threads or offer a full email client, and it will not write cold outreach.
