One of our customers wants to downgrade from the professional Maketing Hub to the Starter edition because they only use the email marketing tool in Hubspot. All other campaigning is done in Salesforce.
The connected app (Salesforce) is working fine & we need to be sure wa can keep the sync with Salesforce bacause we use the contacts for sending emails via Hubspot.
My concrete question: are we sure can keep our sync with Salesforce with the Starter edition (and mybe upgrade the number of contacts). The current database contains around 2500 contacts.
