Hey @DTeam34, It’s only possible to use SMTP API to send “transactional” emails. You cannot use it to send “marketing” emails. There is no way to use the API to send marketing emails from HubSpot. If it is indeed transactional email you are interested in I recently recorded a [video walkthrough](https://share.vidyard.com/watch/GmAL3zqbTx18YCHyjRQR1G) on the transactional email functionality (and how to send email using SMTP API - sample python script [here](https://gist.github.com/jackcoldrick90/a87c7665d5959f01178bf5d30e09ea05)). I suggests checking that out. You will need to ensure that you have purchased the transactional email add on in order to specify the correct scope to use the APIs. More information can be found below: - [Sending Transactional Emails with HubSpot](https://knowledge.hubspot.com/email/how-to-use-transactional-email-in-hubspot) - [Transactional Email Documentation](https://developers.hubspot.com/docs/api/marketing/transactional-emails) - [Transactional Email Add-On](https://www.hubspot.com/products/marketing/transactional-email) I hope this helps!
