Hi,
we have the problem that we can’t use the transactional e-mail /marketing/v3/transactional/single-email/send/ with different attachments on each e-mail. We have to use SMTP.
To use a HubSpot e-mail template with SMTP is complicated.
We can create a HTML template by copying it from a sent test e-mail. In this case, a developer has to put it into the code and direct changes are not possible.
We can also render the response from an e-mail template, but that’s a lot work and may fail. In this case, we also have to implement each coded token in our program.
I think, an endpoint like /marketing/v3/transactional/single-email/render/ which returns the rendered e-mail HTML without sending would be a great soulution for the usage of e-mail templates with SMTP. The parameters can be the same as in /marketing/v3/transactional/single-email/send/
