Email Sub-Addressing is one of those little things we’ve been asked about occasionally in recent years as it has become more popular, and we’re happy to say it’s now available as a standard feature on all of our shared linux hosting plans.
At the most basic level, sub-addressing (also sometimes referred to as “plus addresses”), allow you to dynamically expand on your email address by inserting a “+<tag>” into the username portion of your email address.
For instance, if your email address was “email@example.com”, you will also receive emails addressed to “firstname.lastname@example.org”, “email@example.com” or any other “bob+<something>@purenrg.net” combination.
Some popular uses for email sub-addressing include:
- Organizing emails by topic (+work, +play, +band, etc)
- Services that require email uniqueness (AWS for instance, requires every root AWS account to have a separate and unique email address, so if you have a need for multiple AWS environments, you’ll need unique email addresses (or subaddresses) for each AWS account you wish to maintain).
- Spamtraps/Limiting: One person I know utilizes a “firstname.lastname@example.org” style that they change each month, then they create inbox filter rules to ‘pluck out’ the desirable emails and place them in their actual inbox. Eventually they ‘retire’ a specific subaddress by making a filter that deletes that month on sight.
You can toggle the creation of these subfolders off on an email account by email account basis within cPanel by visiting “Email -> Email Accounts” and clicking “Manage” for the email account you wish to adjust.
