I’ve been seeing a strange trend in my email campaigns recently. Before February 11, my emails were consistently getting 300+ link clicks. But after that, the numbers dropped significantly—now getting less than 100 clicks across multiple lists (not just one).
Is it just me, or is anyone else experiencing this since mid-February?
Could this be an inbox placement issue? A deliverability change? Something else? Would love to hear your thoughts or any advice!
Hi Irfan, welcome to the Community! 
I did reply to the email you sent our team yesterday regarding this drop in clicks on your account. However, for the benefit of the community, there haven’t been any systemwide deliverability issues that would have affected these click rates from our side.
What we did find was that a certain cluster of domains were opening and clicking links in these messages immediately after receiving them in the beginning of February, but then that click activity dropped off after mid-month. This type of activity can be caused by mail scanning software at inboxes - a rise in this activity can mean the filter is reviewing content for security reasons, and a fall in that activity can mean the reason for that review has passed. This fall can sometimes be due to your own sender reputation being seen as good enough to no longer warrant that level of review. But there can also be other external causes that are not visible outside of those systems, such as a flood of other malicious messages targeting their domains, a malfunction on their side, or a multitude of other reasons.
In general, the best thing you can do to minimize that kind of scrutiny by filters is to regularly review your lists for people who are not opening your emails consistently. People who do not open your emails for long periods of time can cause filters at their domains to scrutinize your email more before letting it into the inbox. Deleting those inactive subscribers will help reduce the risk of that happening.
