Email Deliverability for Fractional CMOs
DIRECT ANSWER
Email deliverability is the rate at which sent emails actually reach a recipient's inbox — not just avoid a bounce, but clear spam filters and land where they're read. It depends on sender authentication (SPF, DKIM, DMARC), list hygiene, engagement history, and infrastructure reputation. Industry inbox placement benchmarks sit around 85–90% for well-maintained senders. For Fractional CMOs, this is especially relevant because running marketing strategy for multiple clients simultaneously with minimal personal bandwidth.
What email deliverability means for Fractional CMOs
A fractional CMO juggles 2–5 clients at once — each with its own brand voice, channels, and KPIs. The bottleneck is execution bandwidth, not strategic clarity. Every hour spent on production is an hour not spent on strategy.
For a fractional CMO, email deliverability is a lever you need but rarely have time to execute consistently. Three DNS-based standards form the technical floor of deliverability. SPF (Sender Policy Framework) specifies which mail servers are authorized to send on your domain's behalf. DKIM (DomainKeys Identified Mail) cryptographically signs each message so receiving servers can verify it wasn't tampered with in transit. DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM fails — quarantine, reject, or monitor — and sends aggregate reports back to the sender.

FAQ
Email Deliverability for Fractional CMOs — common questions
What's the difference between delivery rate and deliverability?
Delivery rate measures the percentage of emails not bounced — accepted by the receiving server. Deliverability (or inbox placement rate) measures whether accepted emails reached the inbox versus spam or promotions folders. A 99% delivery rate and a 60% inbox placement rate can coexist, meaning 40% of 'delivered' email is never seen. Inbox placement is the metric that actually predicts revenue impact.
