For some reason scammers have been targeting the email service Sendgrid in a lot of phishing scams recently. They send out very convincing-looking emails about service suspensions or whatever, and the link to fix the issue goes to their own login page mimicking Sendgrid's in order to capture your username and password and presumably hijack your account.
This one is particularly funny and kind of clever though -- they're trying to trigger anti-DEI folks (or people managing a client or employer's corporate branding, or both) to get upset at the prospect of a "Women's History Month" footer being added to all their outgoing emails.
Phishing scams are getting more convincing and legit-looking; this one almost got me. Always look at the sender and the addresses of outgoing links, and if it says to log in somewhere, just log in like you normally do, don't use links in the email.
