Phyre Labs operates the technical email delivery infrastructure for its newsletters and partner communications. Its website explains why recipients may receive messages, what those messages contain, and how to manage or end a subscription. Communications include newsletters, product announcements and industry updates sent on behalf of brands operated by Phyre Labs. The company says addresses are added through sign-ups, business contacts or partner relationships, and that each message identifies its sender and includes a working unsubscribe link.

Phyre Labs authenticates email using SPF, DKIM and DMARC, and says it honors unsubscribe requests immediately and permanently. Recipients can unsubscribe with one click or request removal by emailing [email protected]; requests by email are processed within one business day. Unsubscribed and bounced addresses are placed on a global suppression list to prevent further messages. The company also states that it does not sell or share subscriber data and does not request passwords, payment details or personal documents by email. People can report unwanted or misleading messages, with full headers, to [email protected] for review.
