Email deliverability refers to the ability of an email to successfully reach its intended recipient’s inbox without being blocked or filtered out by spam filters. It is a crucial aspect of email marketing and communication, as it ensures that the messages sent by businesses and individuals are actually received and read by their intended audience. Factors that can affect email deliverability include the sender’s reputation, the content of the email, and the technical aspects of the email server. High email deliverability is essential for effective communication and building trust with customers and clients.
