AI Inbox
An AI inbox is an email client that uses artificial intelligence to summarise, sort, prioritise and sometimes answer emails before the human recipient reads them. It is transforming email marketing metrics and copywriting.
Dark Mode
Dark mode in email refers to how email clients render messages when the recipient has dark mode enabled. It affects colour display, image rendering, and readability. Designers use CSS media queries and hybrid coding techniques to control the dark mode appearance.
Email A/B Test Confidence Level
The confidence level in an email A/B test indicates the probability that the observed result is genuine and not due to random chance, with 95% being the standard threshold.
Email A/B Test Examples
Email A/B test examples show practical testing scenarios that help marketers improve open rates, click-through rates, and conversions through data-driven experimentation.
Email A/B Test Minimum Detectable Effect
The minimum detectable effect (MDE) is the smallest improvement an A/B test can reliably detect given the available sample size, directly affecting how long a test must run.
Email A/B Test Sample Size
A/B test sample size is the minimum number of recipients needed per variant to achieve statistically significant results, determined by baseline conversion rate, minimum detectable effect, and confidence level.
