Attachments for transactional emails
We are currently migrating a lot of transactional emails from a different platform to HubSpot. One of those e-mails is a order confirmation. Currently, it is not possible to send an attachment with a transactional email unless you use the SMTP API. But by using the SMTP API, we can not use HubSpot templates and have to use coded templates instead.
Please make it possible to send attachments with the Single Send API (Transactional Email Addon)
