Email Open Rate
Email open rate is the percentage of recipients who open an email campaign. It is calculated by dividing unique opens by the number of delivered emails. While open rate tracking has become less accurate due to privacy changes (like Apple Mail Privacy Protection), it remains a useful directional metric for subject line effectiveness and sender reputation.

Email Deliverability
Email deliverability is the ability of an email to reach the recipient's inbox rather than being filtered to spam or bounced. Factors affecting deliverability include sender reputation, authentication (SPF, DKIM, DMARC), content quality, list hygiene, and sending patterns. High deliverability is essential for effective email marketing campaigns.
A/B Testing
A/B testing (split testing) is a method of comparing two versions of a webpage, email, or other asset to determine which performs better. Traffic is split between variant A (control) and variant B (treatment), and statistical analysis determines which version produces better results. Common A/B test elements include headlines, CTAs, images, email subject lines, and page layouts.
Click-Through Rate (CTR)
Click-through rate is the percentage of people who click on a link compared to the total number who see it. In email marketing, CTR measures clicks on links within an email relative to delivered emails. In SEO, it measures clicks on a search result relative to impressions. CTR is a key indicator of content relevance and call-to-action effectiveness.
