Blocks not appearing as they do in the website…

I have recently started using MailPoet, and it has been working great. I mainly use it for post notifications where I include the whole post in the email. That has been my preference, but I’m wondering if I might have to make a change.

In my website, I really like the Stackable Blocks plugin, and out of about 12 collections that I have tried, it has the most robust formatting options. One of the Blocks of theirs that I like is an Icon List where you can replace the default bullet icon with a different icon (like music symbols in the above referenced page –> https://polywogg.ca/empty-sky-1969-by-elton-john-pwgm00001/).

However, when MailPoet sends the full page, and it comes to that block, it instead sends a bunch of the upfront code instead:

I asked Stackable and they wondered if the HTML mail client was not accepting more elaborate styles. Which leads me to two questions:

a. Is there a way to fix it so it DOES appear properly in the email?

OR

b. A way to strip out the codes (a filter in MailPoet) that would ignore that type of advanced code?

It was working so well on all my feeds, I didn’t even notice that some of the blocks weren’t showing properly. I can suggest tweaks to Stackable if there is a way to integrate it there or I can embed code in the posts if that works?

I’d like to avoid just sending the excerpt only if I can help it, and I don’t want to give up the blocks, it took me a long time to find ones that worked well.

Any suggestions would be welcome…
