Poor website service and Terrible customer service.A contact form on our website wasn't sending through the emails that it was configured to send. We found this out from irate customers which was far from ideal, and it turned out the form hadn't been working for some weeks.We tested the email address configured into the form. It successfully received emails from multiple external accounts through multiple email providers, so we knew the address was good.Also, other email addresses with the same domain name worked, so it wasn't a problem with our domain.We contacted Squarespace through chat (after waiting 25 minutes for an agent to pick up the chat).We were told "Ok, so I was able to see that the custom address was temporarily placed on a blocklist. We aren't able to see exactly why this occurred, but I was able to request you be removed from it."The problem was quickly rectified, but when I pointed out that we had had no notification of the block being put in place, that we had lost custom due to this, and asked whether this could happen again, the agent went into technobable mode and basically said it had nothing to do with Squarespace and must be a problem on our side. The agent would not accept that Squarespace had any responsibility, even though all other possible causes had been ruled out.As we can't rely on the Squarespace service for our business, we will be looking elsewhere.
