Frequently asked questions
What is a good email open rate?
Average open rates vary by industry — typically 20–30% for B2C and 15–25% for B2B. Triggered emails (welcome, abandoned cart) often exceed 40%. If your open rate is below 15%, focus on improving subject lines, sender name, and list hygiene.
What is click-to-open rate (CTOR)?
CTOR measures how many people who opened your email also clicked a link, calculated as (Clicks / Opens) × 100. It isolates email content effectiveness from subject line performance. A healthy CTOR is typically 10–20%.
How do I improve email deliverability?
Keep your list clean by removing bounced and unengaged addresses. Authenticate your domain with SPF, DKIM, and DMARC records. Avoid spam-trigger words and maintain a low complaint rate. Aim for a delivery rate above 95%.

Key Email Marketing Metrics Explained
Email marketing success depends on tracking the right metrics at each stage of the funnel. Delivery rate shows your sender reputation and list quality. Open rate reflects subject line and sender name effectiveness — if subscribers do not open, nothing else matters. Click-to-open rate (CTOR) evaluates your email body: images, copy, and calls to action. Finally, conversion rate and revenue per email sent connect email activity to business outcomes. Tracking all five stages gives you a complete picture of campaign performance and a clear roadmap for improvement.
Email ROI — The Most Profitable Marketing Channel
Email marketing consistently delivers the highest ROI of any digital marketing channel — industry studies cite returns of $36–$45 for every $1 spent. Revenue per email sent is the single number that captures this: even a modest $0.10 per email sent on a list of 50,000 generates $5,000 per send. Improving open rate from 20% to 25% and CTOR from 15% to 20% can compound to increase revenue per email by 60% or more without spending a single additional dollar on acquisition.
