SendGrid Emails Getting Rejected as Spam

I receive only Spam Mails from Sendgrid. Goes direct to Spam folder and try to report Sendgrid everywhere I can. Maybe they get blocked by most mail servers and make them think about their policy in "hosting" all these Spammers.

A question from 2015 which is sadly still relevant today as usage of SendGrid increases.

My organization has blocked all SendGrid mails except for those on the paid tier using fixed IP addresses with resolvable public DNS names (such as sendgrid1.sampledomain.tld) which we then whitelist.

There are now far too many domain impersonation, phishing and other spam mails coming in from SendGrid for us to allow everything from them - roughly 10 000 mails over a seven day period, which is far too many to manually report to SendGrids abuse department.

So my answer would be that switching to the paid tier of SendGrid is the better option if you like a better chance of your mails arriving intact at their destination.

In this case it's most likely because you are sending such a short message, with a link to 'reset your password' from a non-whitelabelled email address (the email address you're sending from cannot be verified against the actual domain), and the link may also be a different URL. It's probably getting pulled up as a potential phishing email.

You can rectify this by white labeling your domain and email links via the SendGrid dashboard, it's easy to do and should improve your deliverability.
