Soft Bounce is a term in email marketing referring to emails that reach the recipient's server but are returned undelivered due to temporary issues.


A 'Soft Bounce' is a term used in email marketing to describe a situation where an email is successfully sent to the recipient's mail server but is returned undelivered before it reaches the recipient's inbox. The causes for a soft bounce are typically temporary issues, such as a full inbox, a server that is temporarily down, or an email message that is too large.

Usage and Context

Email marketers monitor soft bounces to gauge the health of their email lists. A high rate of soft bounces could indicate that a significant portion of the email list is inactive or that there are technical issues preventing successful delivery. It's important to note that if an email address continues to soft bounce in multiple campaigns, it may eventually be considered a hard bounce, which could negatively impact the sender's reputation.


What's the difference between a soft bounce and a hard bounce?

A soft bounce is usually caused by temporary issues, such as a full inbox or a server being down. A hard bounce, on the other hand, is caused by permanent issues, such as a non-existent email address.

How can I reduce the number of soft bounces?

There are several ways to reduce soft bounces, such as cleaning your email list regularly, ensuring your emails are not too large, and ensuring that your email server is reliable.

Related Software

Email marketing software like Mailchimp, SendinBlue, and Constant Contact provide features to monitor and manage soft bounces.


Monitoring soft bounces helps maintain the health of your email list, ensures that your emails are being delivered successfully, and protects your sender reputation.


Soft bounces are an important metric for email marketers to monitor. While they are typically caused by temporary issues, a high rate of soft bounces could indicate underlying problems that need to be addressed.
