About 6-7 months ago, we started seeing pretty large amounts of spam from them. I've personally tried reaching out to Twilio / Sendgrid leadership to alert them to the issue.
The KAM.cf ruleset has rules that mark sendgrid higher due to the proclivity for phishes. Krebs as done an article on it: https://krebsonsecurity.com/2020/08/sendgrid-under-siege-from-hacked-accounts/ mailop, the SA mailing list and others have all discussed the issue for months. Invaluement released a plugin / list for this issue as well - See https://www.invaluement.com/serviceproviderdnsbl/ Until Sendgrid acknowledges and works to resolve the issue, I must recommend that they are avoided.
