Independently observed by Siftbox's subscriber panel · 4 emails analyzed sonos.com
What Sonos actually put in front of our panel, counted by how many emails featured each — the products they lead with, not what they stock.
Every verified offer from Sonos, plotted by the day our panel first saw it.
Every offer below was detected in an email our panel inbox received — nothing is scraped or guessed.
Give brands your Siftbox address instead. You'll get the real sales and skip the filler — automatically.

Siftbox operates its own panel of subscriber inboxes that sign up for brand newsletters the same way any customer would. Every email received is analyzed for offers, discount depth, and send patterns. No individual inbox is ever exposed — 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.
