Only the newsletters
worth opening.

You like the brands you follow. You just don't need every email they send. Siftbox gives you a separate address for signups, reads what comes in, and forwards only the ones you'd actually want.

How it works

Three steps between you and a quieter inbox

01
Get your Siftbox address
A dedicated email address you use only for newsletter signups, separate from your real inbox.
02
Tell us what you care about
Once a newsletter arrives, pick the categories worth hearing about. Skip the rest.
03
Only the relevant ones land
Receipts and login codes always pass straight through. Everything else waits in Siftbox, so your real inbox only hears what you'd actually open.

Common questions

Will I still get my receipts and login codes?
Always. The essentials, order confirmations, shipping updates, and login codes, pass straight through to your real inbox untouched. It's only the marketing that Siftbox actually sifts, forwarding the emails you'd want and quietly holding the rest until you feel like looking.
Do I have to change my email everywhere?
That's up to you. Keep your real address wherever you're happy with it. For any brand you want filtered, whether it's a new signup or one you already get, just switch it over to your Siftbox address, and everything it sends from then on runs through the filter.
Where do the held emails go?
They wait in Siftbox so you can review them and pull anything you want into your real inbox, then they clear out on their own to keep things tidy. Since these are the emails Siftbox judged you could skip, the ones you'd actually want were forwarded to you already.
How fast do my emails arrive?
The emails you've chosen to receive land in your real inbox the moment they arrive, with no delay, and receipts and login codes are the same. The only wait is for held mail you decide to pull in yourself, which is delivered at the top of the next hour.
Is it really free?
Yes, and it stays that way. There's a free plan that's here for good, so a quieter inbox won't cost you anything. Setting up takes about a minute.
