New contact and company cannot be enrolled in sequence

Has anyone else experienced this issue? This is a new contact; the company is also new and has a unique domain (no similar domains from previous companies and contacts)

How can this be enrolled in a sequence?

Hi @Zenitsu22,

HubSpot has documented bounces on this email domain before - either in your portal or globally. You can check on the individual contact record in the property “Email hard bounce reason” or check if you see a note about a global bounce.

If you think that this is a mistake, you would have to reach out to HubSpot support in-app via chat or email.

Best regards!
