When you create an account, HubSpot will set up a conversations inbox with a fallback email address. A fallback email is an email that HubSpot provisions that allows you to use certain HubSpot tools, such as ticket automation, if you haven't connected a shared inbox yet. The fallback email is also used if your shared inbox is suddenly disconnected from the conversations inbox.
You can also use the fallback email to immediately start sending emails from the inbox.
You can customize the fallback email's from address, routing rules, and email signature signature. Set up the fallback email when you set up your conversations inbox, or enable it from your inbox settings.
Please note: this signature only applies to emails sent directly from the conversations inbox. If you send an email from a record in the CRM, the email signature you configured in your Profile & Preferences will apply.
If you made any changes to your configuration or routing rules, your contacts will see the updated from name, from address, and email signature when they receive an email from you.
In addition to the email address automatically included in your conversations inbox, you can connect another team email channel to the inbox, or create additional conversations inboxes for your teams.
