Soft SendSoft Send holds outgoing Gmail messages for 1 minute to 1 hour, giving you time to cancel, edit, or catch a mistake before delivery.
Choose a delay from 1 minute to 1 hour. During the countdown you can cancel, pause, or edit. Undo send, on your terms.
Soft Send adds extra delay and a warning for risky patterns: new recipients, missing attachments, reply-all storms, or sensitive content.
Flag specific people or whole domains, such as your CEO or a client's company, so the wrong message never reaches the wrong inbox.
No Soft Send server, no relay, no tracking. Your email content only ever goes to Google's own Gmail API to send.
A clean queue banner lives right inside Gmail, with live countdowns, pause and cancel on every message.
Just sent something by mistake? Hit Ctrl/⌘+Z within 10 seconds to pull it straight back out of the queue.
Gmail lets you choose a cancellation period of 5, 10, 20, or 30 seconds. After you press Send, you must click Undo before that period expires. Google documents those limits in its official Gmail Help instructions.
Soft Send is a Chrome extension for people who want an automatic Gmail send delay measured in minutes. Send normally, then use the local queue to cancel, pause, edit, or release the message immediately. Actual file attachments stay in Gmail's native sending flow so the files are preserved.
Gmail’s built-in cancellation window is limited to 30 seconds. Soft Send delays delivery before the message leaves Gmail, giving you a configurable window of 1 minute to 1 hour to cancel or edit it. It cannot recall a message that was already delivered before Soft Send was installed.
Install Soft Send, choose your default delay, and send normally. Every protected message appears in a local queue with a live countdown and controls to pause, cancel, or send immediately.
No Soft Send server stores your email content. Risk checks run locally in your browser, and messages are sent only through Google’s official Gmail API.
Not if Gmail already delivered it. Soft Send must be installed before the mistake and configured to hold supported messages. A one-minute to one-hour delay keeps future messages cancellable during that chosen window.
Soft Send can automatically delay supported messages sent from Gmail in desktop Chrome. Messages containing actual file or inline attachments bypass the Soft Send queue and use Gmail's native send flow so their attachments remain intact.
