Manually quarantine contacts from receiving marketing emails

Last updated: October 19, 2021

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 sales 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 one of your marketing emails, their quarantined status will be removed and they'll be eligible to receive future marketing emails.

Quarantine an individual contact

To manually quarantine a single contact:

  • In your HubSpot account, navigate to Contacts > 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 Contacts > 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.
