Should you subscribe?

Volume is heavy. Our panel receives ~5 issues a week once subscribed โ€” that's a lot of inbox; a Siftbox filter earns its keep here.

How easy it is to leave

Measured from the unsubscribe route in the mail itself, not from what happens after you use it. Every TLDR AI message our panel received was checked.

One click, in every email

Every message carries a one-click unsubscribe your mail app can action for you, no website visit and no sign-in. Across the 59 emails the panel has received.

Get the writing, skip the pitches

Subscribe with your Siftbox address: the issues arrive untouched, while promos, course launches, and survey requests are held for whenever you feel like looking.

How we know this

Siftbox operates its own panel of subscriber inboxes that sign up for newsletters the same way any reader would. Every issue received is analyzed and checked against what the publication actually sends over time. No individual inbox is ever exposed โ€” data comes from Siftbox's own panel of subscriber inboxes, including mail archives contributed by the founders, blended with anonymized aggregates from Siftbox traffic once many subscribers have received the same campaign. Figures refresh as new email arrives and the site is rebuilt.
