Hi Alex,
To forward a reply to contacts phone, you have three options:
1. Sakari has a native forwarding option to a personal phone using User Notifications.
2. You can setup a workflow in HubSpot with a trigger of a Sakari SMS message received and an action of an internal SMS to your contact owner.
3. You can setup a workflow in HubSpot with a trigger of a Sakari SMS message received and an action of a Sakari SMS to your personal phone number.
Thanks
Adam
