Is there any good reason to accept mail from Sendgrid/Twilio? Enough legitimate customers to warrant ever letting their email through the
shields?
They're getting very close to my three-strikes line at this point:
- Multiple "phishing" emails sent through their service. Most of
these have been the recently-common ones claiming to be from
my domain's email service team, claiming that I need to log in
and reauthorize my account / unlock delivery of some blocked
emails / upgrade my account for more storage / etc. Since I run
my own email servers, that's rather doubtful.
- Twilio/Sendgrid makes it easy for their customers to upload mailing
lists and do mailing runs. Don't see any sort of confirmed opt-in
requirements. They're clearly marketing the ability to do
"promotional" email campaigns i.e. spamming.
- No good abuse-reporting mechanism - in fact I'm far from certain that
they have even a not-very-good abuse-reporting mechanism. They have
channels for their customers to contact them for support, but little
or nothing for abuse reporting.
- They claim to monitor emailings to prevent abuse, but the recent spate
of obvious phishing spams leads me to doubt that this is effective.
Absolutely no good reason Sendgrid are a bunch of scumbags who get paid
to allow these scammers to send out these spam emails though their
"service".
They are extremely spam friendly and try and list wash when you make
a complaint and don't do much about the actual spammer themselves and
allow them to continue spewing garbage out from their network.
These guys are absolute scumbags I get constant phishing emails from sendgrid.com
Block em they are pure scum that are extremely spam friendly.
I have gotten spam coming a lot of their IP blocks. They just shuffle
the spammer around when you complain and the spam still continues.
Exact IPs owned by Sendgrid.com / sendgrid.net that I have personally
gotten spam from lately are
208.117.55.132 (Aug 1 2020)
149.72.194.202 (July 31 and July 25 2020) AS11377
149.72.50.164 (July 17 2020)
149.72.242.228 (July 17 2020)
198.37.154.211 (July 14 2020) AS11377
50.31.55.12 (May 24 2020)
I have gotten multiples spams from some of these IPs as well.
And this is only a quick scan of my abuse folder as well I may have
missed some.
All of this is as of today's day Aug 20 2020.
