While it has long been a popular feature in free web-based email services, the use of plus addresses has become more widespread in business contexts in recent years. A growing number of companies are using plus addressing to organize and manage inbound emails more efficiently. With the latest iteration, Retarus Email Security<\/a> now fully supports these address variants \u2013 a significant step towards facilitating even more flexibility and user-friendliness in the daily email traffic.<\/p>\n\n\n\n

What is plus addressing exactly?<\/h2>\n\n\n\n

Plus addressing involves users adding extensions to their usual email address by adding a plus sign (+) and following it with the tag of their choice. In this way, they can receive messages dedicated to specific topics without having to set up new email accounts or use a new email address. For instance, john.smith@company.com can be turned into john.smith+newsletter@company.com. In technical terms, the email is still delivered to the original email account.<\/p>\n\n\n\n

In the corporate context, this unlocks an abundance of opportunities to organize one\u2019s inbox more efficiently. Inbound messages can be presorted automatically according to topics or sources, such as +recruiting<\/em>, +events<\/em> or +crm<\/em>. In addition, it becomes easier to trace data leaks and detect improper sharing.<\/p>\n\n\n\n

Why plus addresses pose challenges for email security<\/h2>\n\n\n\n

Although plus addressing may be very handy for users, its benefits have often been restricted due to email security. A lot of systems struggle to interpret plus addresses correctly and thus treat them as unknown or invalid recipients. As a result, emails have either been rejected erroneously or security mechanisms such as directory filters, allowlists or CxO fraud filters have not worked as intended.<\/p>\n\n\n\n

Especially when it comes to sensitive environments with strict security requirements, this may lead to substantial problems, ranging from undelivered emails to excessive workloads for IT administrators.<\/p>\n\n\n\n

Retarus provides smart support for plus addressing<\/h2>\n\n\n\n

With the latest Retarus Email Security update, plus addresses are recognized, processed and correctly assigned at every stage of email traffic. If a company chooses to activate the option in their email system, it will no longer make any difference whether messages are sent to an email address with or without a \u201c+ tag\u201d. The system deals with both types of address in exactly the same way and delivers them to the same recipient.<\/p>\n\n\n\n

Familiar Retarus security functions such as advanced threat protection<\/a>, AI-powered sandboxing<\/a> or our patented post-delivery protection<\/a> of course remain fully effective. The same goes for the correct assignment of quarantine, reporting and analysis features.<\/p>\n\n\n\n

Would you like to actively start using plus addresses?<\/h2>\n\n\n\n

We would be pleased to explain in detail how you can incorporate plus addresses into your email communication \u2013 securely and efficiently. Our support team is happy to help you<\/a> achieve the best possible configuration.<\/p>\n","protected":false},"excerpt":{"rendered":"
