Email domain is the part of an email address that comes after the “@” symbol, typically representing the organization or service provider that hosts the email, such as @example.com.
For example, in john@company.com, company.com is the domain. Businesses often use custom domains to build brand credibility and appear more professional than generic ones like Gmail or Yahoo.
Using a branded email domain improves trust and recognition in marketing campaigns. It also helps maintain control over email security and consistency across communications. Marketers rely on custom domains to strengthen brand identity and ensure their emails are more likely to be delivered and trusted by recipients.
