SendMoi helps you save links to Gmail as polished email cards, so they’re easy to find and act on later. Share from Safari or any app, and SendMoi turns the page into a clean email sent through your own Gmail account. When a link is available, SendMoi can pull in the page title, excerpt, and preview image to build a message that looks great on mobile and desktop. Why people use SendMoi: • Save links to your inbox instead of losing them in tabs, bookmarks, or chats • Share from Safari and the system share sheet in two taps • Send through your own Gmail account • Keep a default recipient and recent recipient shortcuts • Queue items offline when you’re on the go • Retry automatically when the app launches, becomes active, or your connection returns SendMoi is built for speed and reliability. Your Gmail session, saved recipients, and queued items stay on your device. SendMoi does not run its own mail backend. It connects directly to Google to fetch page metadata and send mail only for the links you choose to share.
