Subscribe to newsletter directly with NewsBlur e-mail

So, I am subscribed to a set of newsletter with my Outlook e-mail. I create custom rules to redirect them to my NewsBlur newsletter e-mail (myusername-xxxxxxxx@newsletters.newsblur.com).

I really don’t know why, but some of the rules suddenly stop being processed - it’s a fault on Outlook’s side.

I was thinking, then, that instead of redirecting newsletters to NewsBlur I could… just subscribe to them using NewsBlur’s e-mail in the first place?

Would there be any reason of concern not to follow this route?
