Red Sift Launches BIMI Maker for Email Logos
Red Sift has launched BIMI Maker, a free AI-powered self-service tool that enables brands to get their logos displayed in email inboxes via BIMI (Brand Indicators for Message Identification). The tool guides users through preparing logos, checking email authentication, and applying for Verified Mark Certificates (VMC) or Common Mark Certificates (CMC). It aims to remove barriers like trademark and design requirements that have prevented adoption. Currently, about 50,000 domains publish BIMI records, but only 6,500 have certificates for logo display. Red Sift claims BIMI can increase email open rates by 39%.
Introducing Red Sift BIMI Maker, a first-of-its-kind mark certificate tool
Red Sift BIMI Maker takes your logo from an image file to a filed BIMI certificate application, streamlined through either a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC).
SPF, DKIM and DMARC Determine Inbox Placement
A technical guide explaining how SPF, DKIM and DMARC each play distinct roles in email deliverability for self-hosted mail systems. SPF lists authorized sending IPs in DNS, DKIM cryptographically signs messages and survives normal forwarding, and DMARC enforces alignment between those signals and the visible From address while providing reporting. The author describes common pitfalls (e.g., incorrect DKIM DNS entries), the need to warm new IPs and domains slowly, and operational practices—processing bounces, setting up feedback loops, and keeping lists clean—that matter more than copy for inbox placement. The post notes the author's commercial product AcelleMail but states the guidance is product-agnostic.
