Before an e-mail hits your inbox, it passes through certain tests like e-mail authentication, antivirus scanning, etc. This way, your inbox gets only known contacts’ mail. New senders can authorize themselves by responding to a verification request.
Bluebottle is rich with some useful features like the following:
Bluebottle is easy to use. When an e-mail is received from an e-mail address or domain not on your “Allowed” list, it e-mails the sender a “verification request”. Once the sender verifies himself, the system automatically adds his e-mail address to your “Allowed” list and the message is sent through. Till the time you remove the senders e-mail address from your “Allowed” list, future messages are automatically approved. This set-up effectively blocks spam mails.
Easy to use
Bluebottle is easy to manage and time-saving. Simply add your known contacts to your “Allowed” list so they can avoid verifying themselves. And even if legitimate senders do need to verify themselves, itâ€™s as simple as clicking on a link. Moreover, Bluebottle e-mail accounts can be accessed on the web or using POP with any e-mail program.
Bluebottle can filter out the spam from non-Bluebottle accounts too! Simply add your POP3 and IMAP details. E-mail sent to non-Bluebottle accounts will go through the verification process, and e-mail from known senders will be delivered to your inbox instantly. E-mail from unknown people goes to the pending queue for verification.
Rich text format
Along with massive 30MB attachment size and 1GB storage, Bluebottle lets you send e-mails with rich text formatting.
However, it does suffer from drawbacks like absence of free-form labels or smart folders to organize your mail and no ranking technique for segregating pending mails by the extent to which they resemble spam.
All in all, it is an attractive service and has a long way to go in protecting your e-mail account.
