Lumi is a Gmail add-on that helps you stay on top of every conversation with perfectly timed reminders. Schedule it once, and if there's no reply, Lumi will return the email to your inbox right when it's time to follow up.
Works directly inside Gmail on Desktop and Mobile


Lumi helps you stay responsive without living in your inbox. Track replies, follow up automatically, snooze messages, and pause your inbox when you need focus, all inside Gmail.
Because Lumi is a Gmail add-on, it works on desktop and mobile, right away.
Set a reminder and Lumi will notify you when a reply comes in, even if it arrives before your reminder time. No more checking threads just to see if they answered.
If your reminder expires and there's still no response, Lumi prompts you to follow up so important emails don't quietly disappear into the void.
Snooze an email when you can't deal with it right now. Lumi brings it back when you're ready, so you stay focused without forgetting.
Pause your inbox to stop new messages from interrupting you. Incoming emails route to a separate pause folder, and return when you resume.
Set your inbox to automatically resume at a time you choose. Whether you're out of the office or just need quiet focus time, Lumi will bring your inbox back when you're ready.
When your inbox is paused, Lumi can send a custom auto-reply to let people know you're away - without you lifting a finger. Prefer to stay silent? Simply skip setting up an auto-reply.
Set a reminder on an email. If the person replies before your reminder time, Lumi flags it so you instantly know they answered and can respond faster.
How it works:
Connect Lumi to Gmail in minutes. It lives inside your inbox, so there's no new platform to learn and no extra tabs to manage. On the go? No problem! On desktop or mobile, Lumi keeps you on top of every conversation, wherever you are.
Set a reminder on any email, either in a thread or while composing. Pick your deadline to track the conversation, or select Snooze to have it return later for you to handle.
Lumi handles the outcome automatically. If they reply early, it's labeled Awaiting Reply. If time runs out, it's labeled Follow-Up. If you snoozed it, it returns as snoozed, ready for you.
