Email Deliverability: Scalenut vs Hadrian

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. Scalenut addresses email deliverability as a tool you prompt manually; Hadrian's agents execute it continuously on your live brand data under your approval gate.

What email deliverability means in practice

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.

For marketing teams, email deliverability is a lever that needs consistent, ongoing execution — not a one-off task. The question is whether your tooling runs it continuously or requires manual effort each time.

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.
