Extremely long URLs sent in emails

Hi, I am not sure if this problem originates with WordFence or with SendGrid, which we use to distribute emails from the website (like forum topic notifications). The originating URL links.cadc.net is set in SendGrid. But, links are being sent out in a very long format, like this: https://links.cadc.net/wf/click?upn=QMvZu9o68VgZWha4chI9qR8fiPA9EPhdab6-2FNcIhVXagTxNaDQrxhqXbp3FyRiAcgZhkp1N3eMDed6UirlISAw-3D-3D_VxlAuX98jGTImtRfy8qSMi8kimv4U8vdvQbMU6l6-2FnaVdFDIm8ttWoAsPSGP5UnbvmRKsrJsDg2RYdeSkozrr6ejcrbDS9eef70TJ3vU5XN5sdC7Nifmam6OHoHkX7vXgwG7fIy-2FqEIx6uJ3rlEcTXlKo-2F6IwciDYSdR8qXb3-2Bo3kmigEa9iYbpsPrwVToOP5h0s4fhQQumldUlmSG95n8jZd-2B1u3FPMDaJ3jT0HWgfN2wALJ4AZfejS-2BI5Hhy-2Bl which is actually just this: https://cadc.net/home/cadc-history-and-past-presidents/. Is it a function of WordFence to rewrite URLs? I’ve tried downgrading to an earlier version of WordFence but the problem persists. Any suggestions would be much appreciated.
