Email Bouncing

Bouncing?

First let’s talk about what we define as a bounce in online marketing, this is usually referred as a failure to achieve a goal. However, in email marketing it’s a bit different, it refers to the inability to deliver an email.

This could be caused by a long list of issues. Depending on the problem it might be classified as either a hard bounce or a soft bounce. Every time your system fails to deliver a message, you’ll receive a notification. This note originates from the server of the recipient and it basically states a “cause.”

You will be informed of time and date of the delivery, the name and address of the server and a reason for the bounce. Usually in the form of a code, according to the code and the server we can stablish the problem and classify it.

A Soft Bounce

A Soft bounce means that the email address is valid and the mail reached its destination. It also tells us that due to a temporary error the email bounced back.

This could be caused because the mailbox was full, and as such unable to receive more mails. The server was down or the message was too large for the recipient’s mailbox. An example of this is the trying to send an email to a Gmail account that is experiencing a 502 error at the same time.

A Hard Bounce

This is very different from the temporary problem that generally causes a soft bounce. It occurs when the address is non-existent or when it’s invalid. Incidentally it can also be caused by being placed in a suppression list or a permanent block list.

For example, your spam folder works like that, it redirects what the server thinks its trash email. Then, you decide if you want to keep receiving messages from it or not, if not they are place in a suppression list.

It’s possible that trying to send emails to an invalid address, repeatedly, decreases your reputation with the server. This is because the server might get accustomed to you sending emails that never reach a different server.
