Compare email context input and custom instructions to see how you can steer a draft, then consider tone controls and supported languages for the messages you write. Browser extension availability and mail client support show where each tool may fit into your workflow; free plans and paid-from prices add cost considerations. WriteMail.ai, AI Perfect Assistant, and GPT for Gmail are among the tools to explore.
