How message.best works

1. Forward Flow (from any email client)
  1. 01 Compose your email normally in Gmail, Outlook, or Apple Mail to the real recipient.
  2. 02 Forward the draft (or the sent copy) to process@message.best. We read the original To: line.
  3. 03 Our AI instantly recognizes you + the recipient from your profile & history. Applies your custom rules + chosen level.
  4. 04 We either reply to you with the perfected version (for review) or relay it directly to the recipient from your address.
Gmail / Outlook / Apple Mail ready
No plugins needed
2. Web Composer (recommended)
01 Open message.best and compose directly (or paste any draft).
02 We auto-detect or let you select the recipient profile with saved goals & tone preferences.
03 Choose level + activate any custom goals ("Win negotiation", "Sound exceptionally competent", "Handle delicately").
04 One click: get it back for final review, or approve and we send it on your behalf with perfect deliverability.
Pro tip: Connect your Gmail or Outlook once and we can send directly with your signature, DKIM, and open tracking.
