How are phantom clicks affecting deliverability scores? A friend of mine sent 100 emails and 30 subscribers (or their mailbox providers) clicked on every single link in his message. What is CK doing to help us handle this?

Hey @Neil Benson13, It looks like some of your subscribers with domains that belong to large organizations are using a strict spam filtering system. In this case, the spam filter is automatically checking the links in your email to ensure the links are safe. This high level of security is why you are seeing abnormal clicks in general. 

Unfortunately, this is totally controlled by the subscriber's and there isn't anything you can do to combat this. Automatic clicks are becoming more and more common for business addresses. However, here are a few steps you can take to try and prevent bot clicks:

1. Only use HTTPS links in your emails
2. Monitor content. Content quality plays a big role— not only at the link level, but also image to text ratio and other factors. “Aggressive” email marketing (using emoticons in subject lines, large catchwords, and the like) tends to lead to higher amounts of bot clicks.
3. Sender reputation12 plays a significant role in the amount of bot clicks. The amount of bot clicks for senders with highly engaged recipients is considerably lower. If you haven't cleaned your list of cold subscribers10 in a while, we'd highly recommend doing so.
