How Can A/B Testing Improve Email Marketing Campaigns?

Backlinko highlights that A/B testing can help marketers understand what works and what doesn't, enabling them to optimize their campaigns for better results. Common elements to test include subject lines, email copy, images, and call-to-action buttons.
