Independently observed by Siftbox's subscriber panel · 17 emails analyzed maccosmetics.ca
What MAC Cosmetics Canada 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 MAC Cosmetics Canada, plotted by the day our panel first saw it.
A meaningful sale roughly every 1 week. If you just missed one, the next is about that far out — there is no need to hoard their emails in between.
Every offer below was detected in an email our panel inbox received — nothing is scraped or guessed.
Plus 11 more offers verified since Jul 23, 2026, at the same discount levels. MAC Cosmetics Canada restates a running sale in email after email, and each send is logged separately.
Measured from the unsubscribe route in the mail itself, not from what happens after you use it. Every MAC Cosmetics Canada message our panel received was checked.
Every message carries a one-click unsubscribe your mail app can action for you, no website visit and no sign-in. Across the 19 emails the panel has received.
Give brands your Siftbox address instead. You'll get the ~1-weekly real sale and skip the filler in between — 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. Figures refresh as new email arrives and the site is rebuilt.
