Alias Email Limitations
The alias emails you can configure on DoYouBuzz (email@example.com, for example) are very practical, but they do have limitations. Before using an alias email for personal communication, take a moment to read this article.
An alias email actually forwards messages to your inbox. If your inbox is hosted by a service other than Gmail, certain messages may be rejected as spam. Yes, your email provider may think some legitimate emails are spam (Gmail rejects the occasional message too, but it's rare).
That's why we strongly recommend using Gmail if you use alias emails.
What happens if a service thinks my message is spam?
If your email address provider thinks a message is spam, the sender (the person who sent the message from firstname.lastname@example.org) will receive an email within five days stating that their message was not received.
