    Gmail and Yahoo Bulk-Sender Requirements, Decoded: SPF/DKIM/DMARC, One-Click Unsubscribe, and the 0.3% Complaint Ceiling

    Gmail and Yahoo's bulk-sender rules bind any tenant crossing 5,000 messages a day to Gmail — authentication (SPF, DKIM, DMARC), RFC 8058 one-click unsubscribe, and a spam-rate ceiling enforced in Postmaster Tools. This explainer decodes each requirement, maps it to the Orbit surface that enforces it, and draws the marketing-vs-transactional line both mailboxes already police.

    Email Deliverability Playbook: SPF, DKIM, DMARC, Warmup, and Bounce Handling for Transactional Email

    Email deliverability is the share of your mail that actually reaches the inbox rather than the spam folder or a silent drop. It turns on four levers you control — SPF/DKIM/DMARC alignment, sender reputation, warmup, and bounce handling. This playbook walks the checklist a transactional-email operator runs in Devotel Orbit, as tenant-side controls you own, not platform-mandated claims.

    Transactional Email, Modeled Properly: Sending Identities, DNS Verification, and Streams

    Transactional email breaks differently than marketing email, and the controls that keep it healthy are tenant-owned. How Orbit models a sending identity — a domain, default From fields, reply-to, a sending-stream assignment, and a live DNS-verification state — and why that model is what protects deliverability when email shares an account with SMS, WhatsApp, and voice.
