Definition
Increasing your email open rate means getting more of your delivered emails actually opened. Open rate is driven primarily by what recipients see before they open: the sender name, subject line and preview text, plus how relevant the email is to them.
Start with the sender name. Using a recognizable person or brand name builds trust and recognition, so subscribers are more likely to open. Next, craft subject lines that are specific, curiosity-driven or value-focused, and use preview text to reinforce them.
Segmentation is powerful. When an email is clearly relevant to a recipient, they open more often. Finally, remove inactive subscribers who no longer engage; they drag down your rate and can hurt deliverability.
Why It Matters
This matters because the choices you make here show up directly in your results. Finally, remove inactive subscribers who no longer engage; they drag down your rate and can hurt deliverability. When this is handled well it supports engagement, delivery, and the trust subscribers place in your brand; when it is neglected, the effects tend to show up in declining performance and harder-to-fix problems further down the line.
