When it comes to email I just have my server reject any containing links that point to URL shorteners. I’m not stupid enough to click them anyway but it’s safe to assume you’re just a scammer or some other lowlife, even if you’re otherwise considered a reputable business.
Shocking. That's what we get for expecting companies to be benevolent stewards of the internet. They tricked us for a decade and a half but the sheep's clothing are coming off.
Host your own URL shortener with Yourls. It's great, loads of useful plugins too. (dot)ink domains are cheap so you can have fun with namel.ink like I did.
