If you purchase the transactional email add-on, you can send emails over a dedicated IP address for commerce receipts, account updates, terms of service changes, and other essential business transactions.
Before you start sending transactional emails through HubSpot, you must first set up your dedicated IP address in your HubSpot domain settings. Once the DNS setup process is complete, your transactional IP address will be ready to use immediately.
Once your dedicated IP address is connected, you can create and send a transactional email directly in your HubSpot account, or you can use the transactional email API to send emails using an SMTP API or single-send API token.
Please note: to purchase the transactional email add-on, you can contact your HubSpot customer success manager or sales representative for further details.
Marketing emails are defined as outreach to people who have opted in to communication from your company, and require an unsubscribe link. Transactional emails are relationship-based, and are generally triggered by an action taken by the recipient (e.g., an account signup, purchase receipt, invoice, or password change).
Depending on the laws of the recipient's country, it's possible you may be allowed to include marketing information in a transactional email, such as a list of related items in an email receipt. However, it's strongly recommended you limit the content of a transactional email to focus on an already agreed upon transaction or updates on an ongoing transaction. Your legal team is the best resource to give you compliance advice for your specific situation.
To send a transactional email through HubSpot or via the single-send API:
Please note: HubSpot will deliver a transactional email to a contact regardless of their quarantine status, subscription status, or double opt-in status. If a contact marks a transactional email as spam and a spam report is generated, it may appear as an unsubscribe event in HubSpot.
If you want to integrate with a third party or internal system to trigger your transactional email and incorporate data stored outside of HubSpot, you can generate a token to send transactional emails via the SMTP API. These emails will include the HubSpot tracking code that allows full engagement tracking and measurement.
You can generate and manage your tokens directly in HubSpot, or you can use the transactional email API. Learn more in HubSpot's developer documentation.
Please note: make sure you copy the password and store it in a secure place, as you cannot retrieve it later for security reasons. If you lose your password, you can always reset it by following the instructions below.
You can use the username and password associated with an SMTP API token to send transactional emails from your own internal system or a third party integration.
After you start sending emails using the token, you can analyze certain metrics like open rate and click-through rate in your HubSpot account. If you misplaced the token's password, you can also reset or delete it.
Please note: if the user who created the token is removed from your HubSpot account, the token they created will remain in your account and can still be used to send transactional emails. To delete a token, follow the instructions above.
