Is there a limit to how many emails I can send to my @kindle.com account, per hour?
It seems as though there might be a limit to my @kindle.com account in terms of how many emails I can send to it. I'm currently testing Instapaper to send articles to my Kindle, and the first few times I sent something there were no problems. But after two or so articles that I sent within a five minute span, future articles too significantly longer to arrive, with the next three taking 15 minutes or so, and then a few more after that taking at least two hours.
Is the @kindle.com just something clogged up at this particular time, or is there really a limit to how many emails you can send at a time before it becomes really slow? Would it be better t use Instapaper to send daily digests, once a day?
