If your scheduled email does not send as expected, make sure your inbox is successfully connected to HubSpot.
Please note: these steps are specific to scheduling one-to-one emails in the CRM or through the HubSpot Sales Chrome extension. Learn more about scheduling marketing emails in the email tool.
To ensure your connection is still active, reconnect your inbox.
If you scheduled the email using the HubSpot Sales Chrome extension in your Gmail inbox, refresh Gmail to restart the extension. Then reschedule your email.
