I'm building a custom content block for SFMC using the Block SDK. Most of the resources I checked recommends to use Heroku to host the block's configuration UI. I'm wondering why nobody mentions CloudPages for this. Are there any specific limitations?
I also want to confirm the cost implications before deploying it widely on a CloudPage.
My Setup:
- Custom content block UI hosted on CloudPages
- Marketers open the block, fill in form fields
- JavaScript generates AMPscript-based HTML using the form values
- The generated HTML is saved to the email using sdk.setContent()
My Understanding:
The CloudPage is only accessed when marketers configure/edit the block (minimal Super Message usage) Email recipients receive pre-generated HTML stored in the email message Recipients never access the CloudPage Cost = only Super Messages for marketer configuration, NOT per email send.
My Question: Is my understanding correct? If we send this email to 100,000 recipients, will we only incur Super Messages for the initial block configuration (when the marketer opens it), or will each of the 100,000 sends also consume Super Messages?
