Hi there,
I'm new to Squarespace having moved my blog from GoDaddy Website+Marketing.  The site was easy to build but I'm having an issue with how to notify subscribers when I've got a new post.  With my GoDaddy product, as soon as the post was published to the site it automatically sent an email to all subscribers with the post and a site link.  Squarespace is asking me to enter business details of business name, address and tax registration before an email can be sent to subscribers, supposedly due to anti-spam legislation - what's that all about?  I'm a blogger, I've no e-commerce on my site and I'm not trying to sell anything.  I am not a business and do not have the information they want in order to send out the email.  Why did GoDaddy not require this information but Squarespace do?  
The help articles don't really shed any light on it either.  They suggest buying a PO Box - really!!  
Can anyone here help?  Am I just doing something wrong?
Thanks

I'm re-opening this old post as it's the first I've found that might be able to answer my issue.  With a personal blog site, why is a business address required when the blog is not a business?  My old site was hosted by GoDaddy on their Website+Marketing plan and there was no need for a business address for their email campaigns which were sent out automatically when a new post was published.  I can't find any way to do this in Squarespace - it's extremely frustrating
