Mark your calendar

No dated sales yet. This fills in when Mastermind Toys announces a sale with a date attached, or repeats one often enough for the timing to be worth predicting.

Should you subscribe?

Volume is manageable. Our panel receives ~4 emails a week once subscribed — steady, not a bombardment.
Real sales are periodic. A meaningful sale comes around about every 1 week — you can safely ignore most of what arrives in between.
Discounts are verified. The deepest offer we've confirmed from an actual email is 50% off — not a claim, an observation.

How easy it is to leave

Measured from the unsubscribe route in the mail itself, not from what happens after you use it. Every Mastermind Toys 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 19 emails the panel has received.

How we know this

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.
