Klaviyo Deliverability: Reputation Before Design
Why design gets praise but deliverability decides revenue
What inbox providers actually evaluate
The costs of ignoring deliverability
The priority checklist for Klaviyo senders
If your email doesn’t reach the inbox, design doesn’t matter. Inbox providers (Gmail, Outlook, Yahoo) score authentication, engagement, reputation, permission, volume consistency, list quality—not aesthetics. Treat deliverability as your behavioural trust score and monitor it relentlessly.
Do this now:
Authenticate: Valid SPF/DKIM/DMARC, aligned domains, consistent headers.
Audience quality: Mail opted‑in, engaged segments; avoid third‑party lists.
Warm up: Start with engaged Gmail/Microsoft cohorts; scale gradually; monitor inbox placement.
Third‑party sends: Ensure partners use authenticated infra; align frequency/content.
Educate teams: Uncoordinated global sends can tank domain reputation.
When you prioritise deliverability, design finally gets the chance to perform.
Q1: What’s the #1 deliverability mistake?
A: Sending to unengaged lists and ignoring DMARC.
Q2: Does Klaviyo help?
A: Yes—single‑step list‑unsubscribe headers and clear infrastructure settings streamline compliance.
