Uniform Resource Locator

A Uniform Resource Locator (URL) is a specific type of web address used to locate and access resources on the internet, like websites, images, or documents. It typically includes: 

• A protocol (e.g., http or https) 
• A domain name 
• An optional path, query string, or fragment identifier 

Example: https://mailgun.com/email-api/ 

In email marketing, URLs are commonly used in CTAs (calls-to-action) to guide recipients to landing pages, promo offers, or product pages.
