recipientEmail

recipientEmail is a term used in information systems to refer to the email address of the intended recipient in a message, form, or data payload. It is commonly represented as a field or property in databases, APIs, and user interfaces and is essential for directing communications to the correct recipient. In many applications, recipientEmail is used to populate the To header of outgoing emails and may be accompanied by additional fields such as recipientName, recipientID, or role-based distinctions.

Format and validation typically treat recipientEmail as a string. Syntax validation aims to ensure the value conforms to widely accepted email address formats (often aligned with RFC 5322, with support for Unicode via RFC 6532 in modern systems). Some implementations also perform DNS validation to check the existence of the domain or MX records, though validating mailbox existence is not always reliable or feasible. Length restrictions and normalization (such as case-insensitivity for the local part in some systems) may also apply.

Usage considerations include privacy and security practices, such as restricting access to the recipientEmail field, masking addresses in logs, and ensuring secure transmission (e.g., TLS) when delivering messages. In addition to single-address usage, systems may support multiple recipients by using an array of recipientEmail values or by employing mailing lists or distribution groups.
