Ready to Send
What is Ready to Send?
Ready to Send is a Gmail add-on that drafts email replies in the background while you work. Install it from the Google Workspace Marketplace, open it once in Gmail, and it starts monitoring new unread messages that need a response. Drafts land in your inbox within minutes, ready for you to review, edit, or send.
The tool is built around automation rather than on-demand prompting. It skips newsletters, promotions, and no-reply messages, then writes contextual replies that follow your tone and any custom instructions you set globally or per contact. Intelligent Snippets let you store reusable blocks like refund policies or onboarding steps, which the assistant pulls into drafts when relevant.
Ready to Send targets professionals, support teams, and anyone chasing Inbox Zero who lives in Gmail. It runs on desktop and mobile Gmail, supports 100+ languages, and lets paid subscribers connect their own OpenAI or Anthropic API keys for model choice.
Inbox Zero
What is Inbox Zero?
Inbox Zero connects to Gmail or Outlook and uses AI to label incoming mail, draft replies in your voice, and surface what needs attention first. You get pre-written responses waiting when you open your inbox, plus bulk unsubscribe tools for newsletters you never read. The product works on web, iOS, Android, Slack, and Telegram so you can triage mail without living in your email tab.
Most email assistants stop at summarization. Inbox Zero also blocks cold emails, files attachments automatically on higher tiers, and pulls calendar and CRM context into drafts so scheduling replies match your real availability. The codebase is open source with 9k GitHub stars, SOC 2 Type 2 certification, and a self-host option for teams that want full control.
Starter plans cover solo operators who want labels, analytics, and reply drafts. Plus adds Slack, Notion, Stripe integrations, and an unlimited knowledge base. Professional adds team analytics and dedicated onboarding. Over 20,000 professionals use Inbox Zero, and every paid plan includes a 7-day free trial.
