Latest Hero Cosmetics emails
The stack behind the sends
Hero Cosmetics sends with Klaviyo and publishes a DMARC reject policy.
Sends with
Domain authentication
Mail failing authentication is rejected outright, the strictest setting.
SPF also authorizes Microsoft 365, Mailchimp and Mandrill to send as this domain, which usually means other tools sit alongside Klaviyo.

How this is measured
Every figure comes from real Hero Cosmetics emails captured in Inbox Archive, not from a survey or a vendor report. Medians and the campaign mix appear once a brand has 12 campaigns archived, and the day and time charts once 12 of them are scheduled sends. Campaign types are sorted automatically. Discounts are read from subject lines, and a copyable code counts only when one appears in the email, so offers applied at checkout are missed.
