My click-through rates are unusually high

As we have already mentioned on other occasions, there are some really aggressive anti-spam filters. If your CTR or click-through rate is unusually high, it is possible that a spam filter hase cause it: some filters click on the links in the campaigns you send to your users to check that they are not malicious and that it is not a spam message.

We would like to be able to distinguish what percentage of clicks come from spam filters and what percentage come from real clicks to give you more detailed statistics, but unfortunately it is not possible to differentiate between the two. However, if you see a very high number of clicks coming from the same domain, it is likely to be a spam filter.
