What is SMTP and how does it relate to Email Marketing?
SMTP (Simple Mail Transfer Protocol) is the backbone of email transmission. It ensures the delivery of your marketing emails from your server to the recipient's inbox. By using authenticated SMTP servers, marketers can improve the deliverability and reliability of their email campaigns. Authentication mechanisms like DKIM, SPF, and DMARC further enhance the security and legitimacy of emails, reducing the chances of being marked as spam.
