SendLock

Stop emails after hitting send. SendLock adds a customizable delay to Gmail so you can undo, edit, or cancel before damage is done.

Ever hit send and immediately wish you could take it back? SendLock is a Gmail Chrome extension that adds a customizable delay after you hit send. During that buffer, you can stop the email, reopen it, make changes, and resend it when you are ready. It is like an undo send button that actually gives you enough time to catch your mistake. WHY SENDLOCK EXISTS: Gmail has a small undo notification that appears for a few seconds after you send. But that is not a review window. It is a countdown. By the time you realize something is wrong, it is already gone. SendLock is different. It holds your email in a real pause before it ever leaves your inbox. You choose how long that delay lasts. During that window, you can stop the email, reopen it, fix whatever needs fixing, and send it again when you are ready. It is not a notification you have to race against. It is a buffer you control. WHAT IT CATCHES SendLock helps you prevent the email mistakes that cost money, trust, and relationships: Sending an email to the wrong person or replying all by accident Forgetting to attach a file before hitting send Including wrong pricing, incorrect numbers, or outdated information Responding emotionally or too quickly to a difficult message Sending a message with typos, errors, or a careless tone Emailing a client, customer, or executive before fully reviewing your message BUILT FOR PROFESSIONALS WHO CANNOT AFFORD MISTAKES SendLock is designed for anyone whose emails carry real consequences: sales teams sending proposals and pricing, account managers communicating with clients, executives representing their company, finance teams handling sensitive numbers, recruiters making first impressions, operations teams managing approvals and contracts, and customer success teams protecting key relationships. If a single bad email could cost you a deal, a customer, or your credibility, SendLock is built for you. HOW IT WORKS Install SendLock from the Chrome Web Store. One click. No setup. No training.

Gmail shows a small notification for a few seconds after you send. But that is not a review window. It is a countdown, and by the time you realize a mistake, it is already gone. SendLock holds your email in a real pause before it ever leaves your inbox. You control how long that pause lasts, and during that time you can stop the email, reopen it, fix it, and resend when you are ready. It is not a notification you race against. It is a buffer you control. Can I customize the delay time? Yes. You choose how long SendLock holds your emails after you hit send. Set the delay that fits your workflow and change it anytime. Does SendLock work with Google Workspace and business Gmail accounts? Yes. SendLock works with both personal Gmail and Google Workspace accounts. If you use Gmail in Chrome, SendLock works for you. Will SendLock slow down my Gmail? No. SendLock is lightweight and runs quietly in the background. You will not notice any difference in how Gmail loads or performs. The only thing that changes is that your emails are held for your chosen delay before being sent. What happens if I do not stop the email during the delay? It sends normally. SendLock only pauses the email for your chosen window. If you do not take any action, the email goes out automatically once the delay ends. No extra clicks required. Does it work on every email I send? Yes. SendLock protects every email you send from Gmail in Chrome. You do not need to turn it on or remember to activate it. Once installed, it runs automatically on every send. Is there a plan for teams or companies? Yes. SendLock offers both individual and team plans.
