What a good open rate looks like

Opens ÷ sent

Open rate is the share of delivered emails that were opened — your first signal of subject-line and sender strength.

Cold vs. warm

Cold outreach typically lands 15–25%; warm or opt-in lists run higher. Context matters more than a single number.

Move the needle

Lift opens with tighter targeting, better subject lines, strong sender reputation and clean, verified lists.

Open rate = (emails opened ÷ emails sent) × 100. It measures the percentage of recipients who opened your email.

15–25% is typical for cold outreach. Above 25% is good and 30%+ is excellent — usually the result of sharp targeting and strong subject lines.

Common causes are poor deliverability (landing in spam), weak subject lines, an unverified list, or low sender reputation. Warmup and verification fix most of it.

Privacy features like Apple Mail Privacy Protection inflate opens. Treat open rate as directional and pair it with reply and click metrics.
