WriteMail.ai
WriteMail.ai drafts and refines emails from a user's goals or key points, and can also generate replies from a pasted conversation and a reply goal. Users can adjust length, style, tone, mood, emoji use, and language. The site advertises generation in more than 30 languages and lists cold outreach, follow-ups, marketing, customer support, and personal email among its use cases. Browser integrations include a Chrome extension for Gmail, Firefox and Google Workspace Gmail extensions, and an Outlook add-in. The service prepares generated text for the user's default email client rather than sending messages itself. WriteMail.ai says generated messages do not touch its servers and personalized options are stored in a browser cookie. The free plan allows five AI emails per month. Paid monthly plans list 50 emails for Regular at $6.95, 150 for Basic at $11.95, and 500 for Pro at $19.95. The pricing note lists paid access from $5 per month billed annually. The Mail Assistant's real-time suggestions are limited to paid plans. Apps or access are listed for Android, iOS, macOS, Windows, web, and extensions.
