When an email fails to reach a recipient, it is called a bounce. There are two types of bounces: hard bounces and soft bounces. Either type will create an activity indicating that a bounce has occurred, but it's important to know the difference between the two.


Hard bounces

Hard bounces are permanent failures. In other words, no matter how many times you retry to send that same email to that same contact, it will fail. Usual causes for this are:

  • Bad email address
  • Rejected by spam filter

  • Domain doesn't exist


Hatchbuck add an activity to the record for the bounce and will mark these addresses as failed and will not send to them again.This is to help you maintain a better sender reputation and get more emails to the inbox. 


Soft bounces

Soft bounces are non-permanent failures, which means retrying the email may result in success. Example of soft bounce situations would be:

  • Recipient's inbox is full
  • Recipient's server is currently offline

  • The recipient server is overly busy or is currently rejecting messages for a short time


Hatchbuck will record an activity of the bounce in the record; however, we will not fail this email address. That means that you can try to send communication to this contact again in the future. 


To check the reason for a bounce on a specific address, visit the Contact's Activity feed or your Dashboard Activity feed. This is the exact message we have been given from your recipient's server as to why they rejected your email.

  • Dashboard > Email Bounces



Why is my email bouncing to an address I know is valid?


You may have an email address in your contact list that accepts your emails from Gmail, Outlook, Yahoo, etc., but it may hard bounce when sending from Hatchbuck. There are a few reasons this could happen, but here are some of the most common:

  • Your content is being rejected as SPAM: filters may be rejecting a stylized, image-based email even though they accept a text-based one
    • Here are a few articles on how to diagnose if your email content is going to be perceived as "spammy" by a recipient server: Staying out of SPAM, 5 Questions to Avoid SPAM
    • You may also want to check out a service like Email on Acid that will analyze the content of your email to see if it has a high SPAM rating
  • Your recipient's server is rejecting emails from a "mass sender": Hatchbuck and other email services are considered mass email senders and some servers may reject emails from these types of senders on principle
    • If you have a relationship with this individual/company, you may ask them to have their server whitelist Hatchbuck's IP address. Contact our Support Team at support@hatchbuck.com for how to do this.
