Author here. I quickly thought of the title for the article and shipped it. I agree it's clickbait-y and apologize to SendGrid (and any confused readers) but yes, as you say it's _technically_ correct in a very narrow sense – SendGrid's infrastructure and users are sending these emails, it's just that they're fraudulently associated with SendGrid the company.

In any case, I revised the title to "SendGrid isn’t emailing you about ICE or BLM. It’s a phishing attack."

Maybe someone can edit the title of the submission on HN accordingly?
