Trying to use scripting and automation blocks/apps to send HTML emails (similar to sendgrid block) but there is currently only support for sending markdown rendered emails currently. Any workarounds or upcoming updates that anyone knows of?
Welcome to the community, @Ryan_S!
One way of doing this would be to create an HTML-based transactional template on the SendGrid website.
For a no-code way of doing this exact same thing, you could to turn to an external automation platform like Integromat, which allows you to automate the sending of your SendGrid HTML email templates.
