FAQ: Why is my bounce rate so high?
It is important to understand how Predictive manages bounced emails. You may have heard the terms – hard and soft bounces.
A soft bounce occurs when an email has a temporary issue and cannot be delivered to the recipient’s inbox. A few common reasons for this are:
- Mailbox is full
- The recipient’s email server is down
- The email message is too large
When this type of issue is identified, Predictive will try two more times to deliver the email and if the third try is not delivered, Predictive will document the email address as a hard bounce and will stop trying to send the email. If the lead or contact is added to another campaign, the bounce status stays in place and Predictive will not send email to that email address. YOu have the ability to reactivate the campaign member as desired.
A hard bounce can occur for many reasons. The most common are:
- The recipients email address does not exist (this could be because of a typo in the domain or recipient’s name)
- The domain name does not exist
- The recipient’s email server has blocked delivery
Typically hard bounces are permanent and emails cannot ever be delivered to that email address. However, if the reason for the bounce is because of a blocked delivery on the recipient’s end, you will possibly see a trend in bounced emails to a particular domain. This might mean that your sender email address is blacklisted.
Generally, if you have implemented Sender Policy Framework or SPF, blacklisting is minimized.

Corporate spam filters and email firewalls can be very strict and may think you are sending spam if you are trying to connect to a lot of people in the same company. Also the recipient email server may look at a large amount of incoming emails and consider them spam.
There are ways to change this. One is to use our Insight feature to see if it reports your email with possible spam issues. If the test does report issues and you fix them, that may solve the problem.
Another is to do some online research for word that may indicate to a filter that your email is spam – if you have any of those words in your email, then think of another way to state your message.
If a large portion of your emails are going to members at the same company, consider lowering your batch send rate. Our default of 5000/hour will typically not cause this type of flag, but sending in smaller batches can help.

Another way to solve the issue is to contact the recipient (if only one or two are impacted) or the IT group at their company to see if they can whitelist your emails. You may also have to contact the company that runs the spam filter to be whitelisted.
