I don't know anyone there that I know of, but whoever they are they are
capable of advertising on many of the TV channels we watch fairly
regularly. So, maybe bad signup process, hard to say without knowing more.
When you visit their Web site to check it out you're forced to sign up
or login, so that's probably the human factors issue that's driving that.

Speaking of SendGrid.. (Again)

BTW, our guys policy, on detection of 'phishing' the IP is posted to 
RBL's.. otherwise it is probably just scored a little higher..


But does anyone know these guys? Looks like they have bought or used a 
bad mailing list, or they have a sign process being abused heavily..

If, after months of abuse, receivers continue to take the attitude that 
the relatively small amount of wanted mail coming from Sendgrid is an 
obstacle to a complete block, we are simply acting as enablers and there 
is no incentive for them to get a handle on the problem.


IMHO, Sendgrid doesn't consider it to be a problem, they consider it to 
be a feature. As long as the spammers' and phishers' checks don't bounce 
they're happy to accommodate them. As long as the rest of the Internet 
continues to take their abuse, they will continue to dish it out.

I did as well, and was assured that they have a unit whose task it is to ensure 
all Sendgrid/Twilio communications are "wanted, secure and legal."  

Sigh.

I've been very saddened.  Sendgrid was a reputable ESP that has fallen
from grace.  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.

Regards,

KAM
