Email Deliverability
Email deliverability refers to the ability of an email to successfully reach a recipient's inbox, avoiding spam filters, bounces, or other delivery issues. It encompasses technical, content, and reputation factors that influence whether emails are accepted by receiving servers and displayed to users. This concept is critical for email marketing, transactional notifications, and any system relying on email communication.
Developers should learn email deliverability when building applications that send emails, such as marketing campaigns, user notifications, or password resets, to ensure messages are received and not marked as spam. It's essential for maintaining sender reputation, complying with regulations like CAN-SPAM, and optimizing engagement rates in email-driven systems.
