Not all bounces are permanent. Depending on the nature of the bounce, you can try to resend email to a bounced email address, audit your bounced email addresses, or unbounce an email address.

Do I need to do anything with bounced contacts?

HubSpot automatically does not send to contacts that have bounced previously for a permanent reason (e.g. invalid recipient, recipient not found, etc.) in the next send to protect your sender reputation. These contacts will appear in the Not Sent tab in the post-send screen of your email. There is no need to filter or delete these contacts to prevent sending to them. However, you may decide that these contacts are stale and/or bad addresses that are no longer relevant to keep in your database for future email sends.

Because bounces are associated with email addresses and not the contact record itself, you can update your contact's email address and any bounces will not carry over to the new email address. Likewise, if you update your contact's email address to one that has hard bounced in the past, the contact will appear ineligible for email when you make the change.

How do I audit my bounced email addresses?

To see which contacts bounced on one of your emails and to audit the bounce reasons:

  • In your HubSpot account, navigate to Marketing > Email.
  • In the left sidebar menu, click Sent.
  • Click the name of an email.
  • In the email's post-send page, click the Recipients tab.
  • In the left sidebar menu, click Bounced.
  • Click > to expand a particular contact to view the bounce reason, or click the List actions dropdown menu and select Export recipients list to view the bounce reasons in bulk.

Can I remove a hard bounce?

Yes, you can remove hard bounces if you know that an email is valid.

Please note: you should only unbounce a contact if you've confirmed that the contact's email address is valid. Sending to invalid email addresses will have a negative impact on your sender reputation and can prevent you from successfully delivering email to your engaged contacts.

  • Make sure you have an email sending domain connected to HubSpot.
  • Confirm that the contact's email address is valid (e.g., have you recently been able to reach this contact at this email address outside of HubSpot?).
  • If you're aware of a whitelisting, network, or content issue that is indicated in the bounce reason, please verify that the issue has been resolved. Learn how your contacts can ensure deliverability of your marketing emails. Other bounce types such as unknown addresses and/or mailbox full indicate an abandoned email account and generally cannot be recovered/unbounced.
  • Once you've verified that the contact's email address is valid and you've taken steps to prevent future bounces, navigate to the contact's record.
  • In the top-left card, click Unbounce.


  • In the dialog box, review the information about the contact's bounce. Select the I can confirm that this email address is correct checkbox, then click Unbounce this contact.

Please note:

  • HubSpot will refuse requests to audit and/or remove bounces from third-party lists, as purchased lists are prohibited in the acceptable use policy. Learn about what types of contact lists are OK to email using HubSpot.
  • HubSpot does not provide list cleaning services as a permission-based sender, and it is not considered best practice. Instead, it's recommended to remove inactive subscribers or try a re-engagement campaign. There are many third-party service scanner options if you decide to clean one of your lists.
