Email deliverability for B2B programs whose inbox placement isn't what it used to be.

The deliverability audit

Every deliverability engagement starts here. Outputs are a written read on each layer plus a sequenced repair plan.

1. 1

   Authentication

   SPF, DKIM, and DMARC have to be correctly configured and in alignment with each other. A domain with SPF and DKIM in place but a DMARC policy stuck in monitor-only mode is not enforcing anything - it is just collecting reports.
2. 2

   Domain and IP reputation

   Sender reputation is a composite of how major mailbox providers and blocklist operators score the sending domain and IP. Healthy authentication does not protect a domain that has a degraded reputation at Google Postmaster Tools or is listed on a blocklist.
3. 3

   List hygiene

   High unknown-user rates and unmanaged complaint rates are the fastest path to deliverability damage. The hygiene audit surfaces which sending segments are dragging the program and what suppression logic is missing before it accumulates into a reputation problem.
4. 4

   Engagement signals

   Mailbox providers read engagement patterns as signals about whether recipients actually want the mail. Open and click distribution by domain, engagement decay curves, and the suppression logic that protects the sending reputation from disengaged contacts are all part of the read.
5. 5

   Content patterns

   Spam filter triggers are rarely intentional. They are often structural: heavy image-to-text ratios, link domains with poor reputation, or HTML formatting that renders as suspicious in specific clients. These surface in the audit and are corrected before they compound into a reputation problem.
6. 6

   Sending architecture

   Mixing transactional and marketing sends on the same domain is one of the most common architecture mistakes. A complaint surge from a marketing campaign should not be able to damage the reputation of a transactional sending stream. Subdomain segmentation, IP strategy, and warming status are assessed and corrected here.
