SMTP Diagnostic refers to the process of analyzing and troubleshooting issues related to the Simple Mail Transfer Protocol (SMTP). This protocol is fundamental for sending and receiving emails. In the context of Email Marketing, ensuring that SMTP is functioning correctly is crucial for the successful delivery of marketing campaigns. SMTP Diagnostic tools help identify and fix issues that could otherwise prevent emails from reaching their intended recipients.
