Write it while it's easy. Bluma sends it later from your own Gmail, and locks it so you can't quietly take it back.
Being built now. It opens to everyone once Google has reviewed how it uses Gmail. Free to start.
Hi Alex, Before March starts I need to change our fee. The work has grown from two sites to five since we priced it, so from 1 March it will be $2,400 a month. Happy to go through the numbers. Sam
Example. Nothing is sent.
Bluma is send-later for email, with a lock. You write the message while you have the nerve, pick when it goes, and it leaves your drafts. It sends from your own Gmail at that time. Two hours before, it locks: taking it back means waiting ten seconds and writing down why.
Psychologists first showed that people remember unfinished tasks better than finished ones. [1]
studies found that deciding when you'll act makes you more likely to follow through. [3]
fewer app openings when people had to pause and choose first, over six weeks. [4]
Why an unsent email weighs on you, and what makes it stop.
People remember interrupted tasks better than ones they've finished. Later experiments found that goals left unfinished keep surfacing as stray thoughts and make it harder to concentrate on anything else. An email you haven't sent is an unfinished task, so it keeps coming back: in the shower, at the lights, at 2 a.m. [1] [2]
In the same experiments, the stray thoughts stopped once people made a specific plan for the unfinished goal, before they had done anything about it. Plans that name the moment, like 'at nine on Tuesday, it goes', also make people more likely to follow through: across 94 studies the effect was medium to large. Sealing an email with a send time is that plan, and Bluma carries it out. [2] [3]
A short wait plus a deliberate choice changes what people do. In a six-week field study, adding one before an app opened cut how often people opened it by 57%. Bluma puts that pause where you'd pull the email back: two hours before it goes, it locks, and withdrawing it takes ten seconds and a reason. [4]
Draft in Gmail the way you always do. When it's ready, press Seal instead of Send.
Sealed · goes 9:00 TueTomorrow at nine, Tuesday after lunch, whenever you'd rather it landed. The draft leaves your drafts folder, so there's nothing left to stare at.
Drafts · emptyTwo hours before, it locks. At the time you chose, it goes from your own Gmail, exactly as if you'd pressed Send. Bluma keeps nothing afterwards.
Locked · goes in 1 h 40 mBluma asks Google for permission to send email, never to read it. It can't see your inbox, your drafts or your contacts.
The person you're writing to gets a normal email from you. No footer, no tracking, no sign it was sealed.
Before the lock, hold to open the seal. After it, ten seconds and a reason. Taking it back is deliberate, never impossible.
It's for email: Gmail first, then Outlook and Slack. It can't send iMessages or WhatsApps for you. Nobody can, and Apple already built Send Later into Messages.
Being built and tested on Gmail first
Gmail lets you cancel with one click and leaves the draft sitting in front of you. Bluma takes it out of your drafts, locks it two hours before it goes, and tells you when it went.
You always can. Before the lock, hold to open the seal. After it, ten seconds and a reason.
The message you seal, encrypted, until it goes. Then nothing. It can send from your Gmail; it can't read it.
Not yet. It's being built, then tested with a small group while Google reviews it. Email hello@usebluma.com with the Gmail address you'd use and you'll hear when there's a place.
It's named after the psychologist who, in 1927, showed that people remember unfinished tasks better than finished ones.
