All products and plans

To remediate an email suspension, blocklisting event, or trust and safety violation, HubSpot may require you to opt out or quarantine certain contacts. Quarantining a contact will exclude it from receiving marketing emails, but it will remain eligible for use in Sales email tools.

To ensure you can still enroll these contacts in a sequence, send them a one-to-one email, or use them in other tools within HubSpot, you can edit the value of a contact's Email address quarantine reason property on their contact record or update a list of contacts in bulk.

If one of the contacts you manually quarantined replies to a one-to-one email, sequence email, or submits a form, their quarantined status will be removed and they'll be eligible to receive marketing emails again.

Quarantine an individual contact

To manually quarantine a single contact:

  • In your HubSpot account, navigate to CRM > Contacts.
  • Click the contact's name.
  • In the left panel, under the About this contact section, click View all properties.
  • Under All properties, enter Email address quarantine reason in the search box.
  • Hover over the Email address quarantine reason property, then click the edit icon.


  • In the dropdown menu, select a reason.
  • In the bottom left, click Save.

Quarantine contacts in bulk

To quarantine a list of contacts in bulk:

  • In your HubSpot account, navigate to CRM > Lists.
  • Click the name of a list.
  • Select the checkbox to the left of the Name column to select all contacts.
  • Click Edit.
  • In the dialog box, click the Property to update dropdown menu. Search for and select Email address quarantine reason.
  • Click the Email address quarantine reason dropdown menu and select a reason.
  • Click Update.
