DELIVERABILITY IS A SILENT REVENUE KILLER
If 20% of your emails land in spam, you generate 20% less email revenue — but you will never see it in Klaviyo reports because it can only track emails that reached the inbox. Most common triggers: new sending domain without warm-up, sending to unengaged subscribers, missing DMARC record, and spam-trigger words in subject lines.
