The Magic of Gmail Addresses: Dots and Pluses
Gmail, a popular email service used by millions, has unique features in its addressing system that many users may not be aware of. Understanding these can simplify your email experience and even enhance your online security.

Understanding the Role of Dots in Gmail Addresses
Approximately 35% of Germans, around 27 million people, utilize Gmail for various online activities, from shopping to streaming. A common feature in these email addresses is the presence of dots. For instance, an address might be formatted as max.mustermann@gmail.com. It’s important to know that Gmail ignores these dots. Therefore, whether you type your address as m.axmustermann@gmail.com or m.a.x.m.u.s.t.e.r.m.a.n.n@gmail.com, your email will still land in the same inbox. This means no new account can be created with a dot variation of an already existing email.
When Dots Lead to Confusion
Despite the irrelevance of dots in directing emails to your Gmail inbox, their presence or absence can occasionally cause mix-ups. In online forums, there are accounts from individuals who have received emails meant for others. This usually happens due to simple typos – for example, someone intending to send an email to max.mustermann1@gmail.com but accidentally omitting the ‘1’. Another reason might be guessing the email address based on common name combinations.
How Dots Impact Other Online Services
While Gmail might be indifferent to dots in your email address, other services you sign up for might not be. If you use your Gmail address as a username, the exact format you registered with might need to be used consistently at login. Some platforms can recognize and process different dot placements as identical to the original, but this isn’t always the case.
The "+" Feature: Creating Gmail Aliases
Another lesser-known Gmail feature is the ability to create aliases using the ‘+’ sign. By appending a plus sign and any combination of words or numbers after your email address (before the ‘@’ symbol), you can filter and organize your incoming emails more efficiently. For example, registering for newsletters with maxmusterman+newsletter@gmail.com allows you to set up a filter that directly sends these emails to a designated folder. Additionally, this feature helps in identifying sources of spam or tracking which websites have your details, as the alias will appear in any correspondence from those sites.
Using Aliases to Manage Subscriptions and Identify Spam
When you suspect a website might not be secure or spam-free, using an alias such as max-mustermann+shopping@gmail.com during sign-up can be a smart move. If spam emails start arriving, you’ll immediately know their origin. You can view which alias an email was sent to by checking the recipient details in the browser version of Gmail or in any email client.
Limitations of Using "+" in Email Addresses
Despite these advantages, not all websites accept email addresses with a ‘+’. Some might reject these during the registration process, either due to programming oversights or because they’re trying to prevent multiple account creations from the same user using different aliases. It’s worth noting that while Gmail’s handling of ‘+’ conforms to official standards (RFC 5322), some platforms might not support this feature.
By understanding these nuances of Gmail’s addressing system, users can take full advantage of its flexibility, whether it’s effectively managing their inbox or enhancing their online security.
