The membership aspects of the LocalHero platform are based on accounts and every account must have a unique email address. This can create a minor issue when a user needs to have two accounts. For example parents may need to register their children with an organisation on the platform but what to receive all communications from that organisation themselves. One option is to create a second email address but that is cumbersome. In these situation we suggest the use of plus address (also known as subaddressing) Plus addressing, also known as subaddressing, is a simple but powerful feature offered by many email providers like Gmail, Yahoo, and Microsoft Outlook: it allows users to customise their email addresses by appending a + sign followed by a tag or identifier, without needing to register new accounts. The key benefit of plus addressing is that it allows users to categorise incoming emails, identify the source of messages, and manage their inboxes more effectively. With plus addressing, the core email remains the same, but users can append different labels for various purposes. For example, if your email is john.player@gmail.com, you can create customised addresses like john.player+mysonandrew@gmail.com or john.player+questions@gmail.com: the emails will still be delivered to the main inbox john.player@gmail.com, making this feature useful for organising and tracking emails but more importantly from the perspective of the technical email specification these are all unique addresses (and therefore on our platform can have unique accounts) Most email providers offering plus addressing also allow to set up filters to automatically route or handle the messages based on the added tag. Here is a screenshot demonstrating plus addressing in Gmail, using the friends tag:
