Sends with
Domain authentication
Mail failing authentication is sent to spam rather than delivered.
SPF also authorizes Google Workspace and Mailgun to send as this domain, which usually means other tools sit alongside Klaviyo.

How this is measured
Every figure comes from real I · M · 8 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. “Typical Health & Fitness brand” is the median across the 17 Health & Fitness brands that clear the same bar, each counted once however much it 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.
