Yes. Run as many audits as you like, one per second, with no account. Logging in adds rendering previews, fixes in chat and audits on every send.
No. Brew never stores the HTML. It keeps only the report (the findings and the numbers) so its share link works for 30 days, then deletes it.
The audit opens each link from Brew’s servers to see where it lands, the way a link checker does. Tracked links may log that visit, and one-time links such as password resets can be used up, so audit a test copy of those.
Each issue lowers the score by its severity: 20 for critical, 10 for an error and 3 for a warning, counted up to three times per rule. The verdict comes first: any error means the email is not ready, whatever the score.
Brew only replies to senders whose domain passes DKIM or DMARC, so nobody can use the address to email someone else. Paste or upload the HTML instead, or send from an authenticated domain.
It flags the HTML and CSS that Outlook, Gmail and other clients drop. To see the email itself, log in and preview it in 14 real inboxes and devices.
