High Bounce rate from major email providers

Hello-

Getting a very high bounce rate- roughly 80%

I'm not even getting my own subscription - I was, then gmail started blocking me - aol and others are bouncing my Sunscribe By Email - emails as well, I'm throttled back to 19 per batch.

I send one a day, I average 25 posts a day, so there's aound 25 links per email..
