InboxAlly, an email deliverability platform, published new guidance on the importance of sender reputation for email marketing, noting that roughly 21% of legitimate marketing emails never reach inboxes. The release explains that mailbox providers (e.g., Gmail, Outlook, Yahoo) assign trust scores influenced by spam complaints, bounces and user engagement, and recommends best practices such as implementing SPF, DKIM and DMARC, regular list hygiene, engagement monitoring, and using email warmup for new or recovering senders.

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.
