Step-by-step explanation:
A programmatic solution for creating a custom email service would generally involve developing a software application that can handle email functionalities. This can be done using programming languages such as Python, Java, or PHP, along with libraries or frameworks for email handling.
For example, in Python, you can use the built-in 'smtplib' library to send emails, and 'imaplib' library to retrieve emails from a server. You can also use 'flask' or 'django' frameworks to build a web application that includes email features.
By writing code that interacts with email servers, you can create a custom email service that meets your specific requirements, such as customized email templates, automated responses, or advanced filtering options.
