Understanding email marketing metrics

What is a good email open rate?

A good email open rate is generally above 25%. The industry average across all sectors is around 21%. Open rates vary significantly by industry, with government and nonprofit emails often seeing rates above 30%, while retail and e-commerce emails typically hover around 15-20%. Factors like subject line quality, sender reputation, send timing, and list hygiene all play a role. Keep in mind that Apple Mail Privacy Protection can inflate open rates by pre-loading tracking pixels, so your true engagement may be slightly lower than reported.

How do I calculate email ROI?

Email ROI is calculated with the formula: ((Revenue - Cost) / Cost) x 100. For example, if you spent $500 on an email campaign and generated $18,000 in revenue, your ROI would be ((18000 - 500) / 500) x 100 = 3,500%. The average email marketing ROI is around $36 for every $1 spent, or approximately 3,600%. To get an accurate picture, include all costs: email platform fees, design time, copywriting, and any paid tools used in the campaign.

What causes high bounce rates?

High email bounce rates are typically caused by invalid or outdated email addresses (hard bounces), full mailboxes, server issues, or being blocked by the recipient's mail server (soft bounces). Common culprits include purchased email lists with unverified addresses, not using double opt-in, and failing to regularly clean your list. A bounce rate above 5% is a red flag and can damage your sender reputation, making it harder for future emails to reach any inbox. Aim to keep your bounce rate below 2%.

How can I improve my click-through rate?

To improve your email click-through rate, focus on writing compelling call-to-action buttons with action-oriented text, personalizing content based on subscriber segments, keeping emails concise and scannable, and using a single clear CTA rather than multiple competing links. A/B test different layouts, button colors, and copy to see what resonates with your audience. The industry average CTR is about 2.3%, and rates above 3% are considered good. Also ensure your emails render well on mobile, since over half of all emails are opened on phones.
