This happened yesterday:
The first give away is the sender, sendgrid@autovitalsinc.com. Not Sengrid. Now, check the URL on the link provided to check the account activity:

I was curious, so I follow it on my dedicated VM for these kind of things. It took me to a page looking exactly like a Sendgrid login, with a sendgrid.net URL. Upon entering yourmotherisahamster@gmail.com, as username, and yourfathersmellsofelderberries as password, it sent me to https://screenprank.com/gandalf/.
It was well done. This morning the same link renders a blank page with a “Not found” link that takes you to a 404. Hmm…
