Why do emails bounce? How to reduce rejected email    

All of us have mail that bounce. Some of these are directly caused by lack of Netiquette. Nothing is worse than to have this happen at an inopportune time, such as a time-sensitive situation or with a resume, proposal or important document attached. Listed below are some of the causes. For space considerations, detailed explanations will not be given here. Other future blogs will discuss detail, error codes and resolutions. Here are some of the items all should note:

Wrongly addressed email

Changed email address

Large attachments

Host unknown, domain look-up failure

Mailbox unavailable

Mailbox full, or quota exceeded

Altered return addresses

Temporary errors

Unable to relay

Blacklist filters

Content filters

Sales/marketing terms
Unknown attachmentsHTML

ActiveX content

Recipient servers are down or busy

Your email attributes and formats are not correct

References to explicit or illicit terms

It is important to note that there are "soft" bounces. These are when the sent to domain has accepted the sender's message and a final delivery does not transpire. This can often be rectified by the recipient's internal actions or by resending at a later time.

By contrast, a "hard bounce is more serious, meaning the email has been rejected and sender is to blame. 
Also there are temporary errors when the receiving server will adjust or retry internal delivery. Often these conditions are repaired without having to resend a message.

If simple Netiquette is applied in sending emails, the sender's rate of bounces almost always decrease. Obviously, poor use of Netiquette will result in more bounces both for the short-term and the long-term.

“Paul Babicki and Frank Kovacs are co-authoring a new book on Netiquette IQ for job seekers, recruiters and employers (no official title as yet!). This book is a follow up to Paul’s “Netiquette IQ – A Comprehensive Guide to Improve, Enhance and Add Power to Your Email”. This book will be a part of the forthcoming Netiquette IQ compendium featuring a series of books on specific areas of Netiquette; education, sales, social media, etc.

We would desire and encourage feedback from anyone who would like to contribute their thought ideas, even a segment to include in the book. We want the book to cover as many pertinent topics as possible for the job seeker, recruiter and employer.

There will be an acknowledgement page in the book listing those whose ideas or suggestions are used.

 

The persons with the 5 top ideas will be sent a complimentary signed copy of my current book and a copy of the new book when it is published. Comments will be closed on 1/31/2014.
