Email Hosting & Deliverability Configuration
The Situation
A B2B organization sending high volumes of client-facing email — proposals, invoices, and transactional notifications — began noticing that a growing share of its messages were landing in recipients' spam folders rather than their inboxes. The organization managed several domains across departments, each with its own email configuration history.
What Was at Stake
Email deliverability problems rarely announce themselves clearly. A missing or misconfigured SPF, DKIM, or DMARC record doesn't produce an error message; it simply causes messages to fail to reach their intended recipients, gradually eroding sender reputation and, with it, client trust and revenue-critical communication.
The Approach
SPF, DKIM, and DMARC records reviewed and corrected across every domain sending mail, with authentication aligned to the actual sending infrastructure in use
MX records verified against the intended mail provider for each domain, correcting several records left over from a prior provider migration
DMARC policy introduced gradually, moving from monitoring to enforcement, to avoid disrupting legitimate mail flow during the transition
Sending domains and reputation monitored post-implementation to confirm inbox placement improved rather than assuming the fix
Outcome
The organization saw a measurable improvement in inbox placement across its primary sending domains, along with a documented authentication baseline that new domains could be configured against going forward, rather than repeating the same troubleshooting cycle with each new address.
IT Decision-Maker Perspective
Email deliverability is a DNS configuration issue long before it is a marketing or IT-support issue. Treat SPF, DKIM, and DMARC as core infrastructure to audit whenever a domain or mail provider changes, not as a one-time setup step to revisit only after deliverability has already suffered.
