What is the difference between a hard and soft bounce?

When you send out your campaign you'll probably notice that some of your emails won't be delivered.  Emails that can't be delivered are called "bounces."  This can happen for several reasons.  WordFly categorizes your campaign's bounce responses into either soft or hard bounces.

Reviewing hard and soft bounces for a Campaign

 

 

Soft Bounces

 

Soft bounces are emails that exist, but for some reason, they couldn’t be delivered. Generally a soft bounce will be something temporary like a "out of office" message or "full mailbox."  Soft bounces are considered temporary until they are proven to be invalid addresses.

 

What should you do about soft bounce?  You shouldn't have to worry about these too much.  Usually, the next time you send an email it will be resolved.  You should keep an eye out for very high soft bounce rates however, as it can signal a spam blocking issue. Learn more about how soft bounces are handled in WordFly by reviewing the last section of this article.

 

 

 

Hard Bounces

 

Hard bounces are always invalid addresses. The address can be invalid for two reasons: (1) the domain doesn't exist (example "address@notrealdomain.com"), (2) the domain does exist, but the local part of the address is invalid (example "not_a_real_address@gmail.com'). 

 

In very rare cases, the ISP may send back a hard bounce response for a valid email address. The response is still handled as a hard bounce in WordFly. You may try sending to the hard bounce again if the subscriber states the address is valid. If, however, the address hard bounces again the subscriber should reach out to their ISP to troubleshoot why they are sending out a hard bounce.

 

What should you do about hard bounces?  Make sure you aren't sending to invalid addresses.  Remove bad addresses from your list immediately.  Repeated sending to invalid addresses can land you on blocklists and lead to deliverability issues.

How are soft and hard bounces handled?

 

WordFly automatically handles your soft and hard bounces:

 

RESPONSE HOW IS IT HANDLED IN WORDFLY
Hard bounces When this response is received by WordFly the subscriber is flagged as an issue and removed from your future list imports. Learn more about managing hard bounces in your account.
Soft bounces When this response is received WordFly attempts to send the email at regular intervals for up to 72 hours. We retry after 20 minutes and then wait incrementally longer after each attempt before expiring the message after 3 days. The initial soft bounce is logged immediately. Other responses (opens etc) may also be logged for the subscriber if a delivery is successful.

 

 

 

How can you see the bounces in your campaign?

 

There are two ways you can see the bounces in your campaign: Pull a Report or Review the Campaign's Report Summary page.

 

Option 1: Export your Campaign Event Data

 

Review this post to export Campaign Event Data. When configuring the data to export, select hard and soft bounces. This will yield an export that had every subscriber with a hard or a soft bounce.

 

Option 2: Review the Campaign's reporting page under the hard or soft bounce tabs

 

1. Go to Reporting > Dashboard.

 


2. Hover over Campaign, Select View Results.

 


3. Select Hard bounce tab or Soft bounce tab to view report

 

 


4. Select "View" or magnifying glass icon under one of these tabs to see actual emails with these responses.
