Multiple custom shortcodes?

Hi.

I’ve successfully built a custom shortcode to integrate WP Popular Posts output into the Mailpoet newsletter.

However, I’m running into an issue where I can’t seem to integrate two custom shortcodes into one newsletter. For instance, I have a custom shortcode:

[custom:news]

That returns exactly what I need it to.

And I’ve written the code so that it handles two custom shortcodes,

[custom:news]
[custom:videos]

but only the first one works in the newsletter.

Before I dive deeper into why both aren’t returning content, I just wanted to make sure that Mailpoet supports additional custom shortcodes in one email.

My suspicion is it should, because if I repeat one shortcode, a la:

[custom:news]
[custom:news]

I get both… but maybe it’s not calling it twice.

Thanks!
