Dynamic content - email send issues

Hi there,

Hoping someone can help me out :-).

My company are fairly new to dynamic content.

My segments include the following:

However, I sent out an email (with dynamic content to the segments I screenshot above) this morning for an invite to an event and noticed in the default email x2 links were dead links (because we hadn't checked the link). My team asked to send this out to just to the default email. Is this even possible? They asked if we could send an email to just default (with a subject line highlighting error) but I would suggest instead to send this out with an updated subject line on all versions, to all segments with the corrected links in the default version.

The send is slightly complex. I ran a drip and nurture for this particular audience that we are sending this out to. so I set it up so that anyone in the engagement program would receive it and anyone who has already registered in the SFDC campaign wouldn't receive an invite since they would have registered for that event.

Hope this makes sense.

Thanks,
