How we collect

We subscribe to each store's mailing list the way a customer would, and record what arrives. Every figure on this site is a count of emails we received.

What we collect

For each email: the subject, the preview text, the sender, the time it was sent, the platform that delivered it, its size and its count of images and links, and a picture of the email as it renders.

How a brand gets added

We find stores with a public newsletter signup and join the list with an address of our own.

What the figures mean

"Emails a week" is the number of marketing emails one subscriber received, averaged over the weeks we were subscribed. Times are US Eastern. The platform is read from the email's own delivery headers.

What we cannot see

A brand may send some emails only to part of its list. We count what reached us, so a brand can send more than we show. Months when our subscription was interrupted are marked "not collected" and left out of averages.

Corrections and removal

If a figure is wrong, tell us from the brand's page. If the brand is yours, Brand owners covers corrections and removal.
