(Disclaimer I'm fairly new to development in general and this is my first StackOverflow post all and any feedback is greatly appreciated.)
I'm posting here because I'm on a free SendGrid account and their support team has yet to get back to respond and it's been over a week and I'm dying to solve this issue.
Currently, I'm using Sendgrid as an SMTP and recently my emails have stopped sending to the following esp Yahoo, AOL, and Verizon.net but emails send to Gmail just fine.
Because emails still send to Gmail I used "Email Header Analyzer" via mxtoolbox.com to review and meet the recommendations provided. Which I have implemented on. (See screenshot)
The only thing not checked off is the "DKIM Authenticated" in which it's my understanding that when you verify the domain you're using to send emails with SendGrid takes care of that for you.
It's not the email function itself because it sends just fine to Gmail.
My question is has anyone else experienced this issue? If so what was the fix you did that made it work?
Screenshot of my email header analyzer results:
Turns out that my SendGrid account was over the daily email sending limit for the "free plan" and the emails that were sent correctly to Gmail had been doing so because of a pre-existing mail function (not using SendGrid even though SendGrid was still logging these emails).
I figured out this was happening by looking at the "mailed-by:" info when you toggle the drop-down above the email just under the sender email address. Mailed-ByView With SendGrid it would say "mail-by: sendgird.net" SendGird-Mailed-ByView
It would have been nice if SendGrid made my sending limit information a little more apparent but you can find this information about your account by going to "Settings">"Account Details">"Your Products." YourProductsView
I am using Google app-scripts to send out personalized emails to notify clients of COVID19 related changes to their programs. The script read in different parameters which required us to not use Google Groups.
After sending out my messages, I received a disabled notification a few days after saying that it was disabled for spam - luckily I was able to reactive my account. After researching, I realized that part of the issue might be the quota and I definitely surpassed the 1500 email quota set by Gmail. Is this why the account was disabled or was there another reason?
I was thinking of splitting up the emails (~1600) across 10 users moving forward to help balance out the quantity, would this help?
Most likely some users might have "reported" your email to google. Such reporting will speed up the process of disabling your google account.
We are developing an application that will send periodic updates and notifications to users as email. The user can opt-in and opt-out of this service via a subscribe option. However we are finding that some users are making the email as spam and as a result our account is getting suspended... Is there any way to track if our emails has been marked as Spam by a user, so that we can stop sending emails to them...
We have a GSuite service and are using Gmail SMTP to send emails
No.
But you can check if your domain is on any blacklist with tools like mxtoolbox.com. And contact those blacklists with the question what you could do to be removed from the list.
In order for a mail to be classified as spam it has to fail a multitude of tests maybe your mails have specific words in the title or the senders address is way to weird or the header is getting corrupted in a certain way or and maybe that's your problem: many people are custom filtering your emails as junk/spam.
I'm making a user management system for my app, and I need to send users a "forgot my password" email with a token that lets them reset their account password. I signed up for SendGrid through Azure (to get the 25,000 emails per month free, which sounded like a great deal) and wrote some code to use it, but after testing my program a bit I was dismayed to find that only a couple of my emails actually went through.
After going onto the SG control panel, I found that 4 out of the 6 test emails I sent went through, and all of the others were rejected as being spam. I sent an email to mail-tester.com to see what it though my spam score was and it gave me a 4.3/10.
The email in question was a single sentence with a link to the password reset, without any images or other elements. I only sent those 6 emails out, so the volume of my emails definitely wasn't the issue. Still, I'm very puzzled as to why my messages are getting flagged as spam.
Without going to the trouble of making an elaborate authentication setup, are there any basic changes I can make to my system to make it get through to users?
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.
Also check out this article from the SendGrid support team about White Labeling.
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.
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.
In my case my emails are marked as spam because of the anchor label different to the href being actually called.
And that's because of the 'click tracking' setting of sendgrid.
So, if you have something like
yourdomain.com
sendgrid may replace the href and you end up with something like:
yourdomain.com
The sendgrid page being called tracks the click and then redirects the user to the url you originally set. But this sometimes results in your email being marked as spam.
Try to set 'click tracking' in sendgrid dashboard to off: settings | tracking | click tracking.

Always start by setting up Domain Authentication, formerly known as domain whitelabel as #MartynDavies says. Found under Settings -> Sender Authentication in the UI. Should look like this:

To identify problems have a look at Activity and choose to see deferred, drops, bounces, blocks and spam reports.
https://app.sendgrid.com/email_activity
Under Suppressions you can see details for Blocks and Bounces among others:
https://app.sendgrid.com/suppressions/blocks
https://app.sendgrid.com/suppressions/bounces
There you can see errors like:
550 5.7.1 SPF check failed. em1234.mydomain.com does not declare 11.222.33.44 as a valid sender
If it says Verified but you see errors like this then contact SendGrid support.
One thing that has worked is to upgrade from the Free plan to Essentials or Bronze via the Azure Portal. This made a lot of the emails marked as spam pass through.
I had a similar issue when trying to send a user verification email using SendGrid.
In my case, using a custom domain as the sender identity solved the issue.
Make sure to also verify the domain before using it.
I'm using my Google Apps account (Standard version) to send single emails (automatically) to real interested customers.
The problem is that my sender email account has been suspended, because it's been considered as a "spammer" by Google.
What can I do in order to send that kind of emails from now on? I use MailChimp to send massive emails, and I've seen it has an API, called STS, for sending single emails, but it also required an Amazon SES account, so I don't know whether to invest on those services or doing something else.
What do you recommend for this case?
You should try a service that specializes in sending "transactional" emails, such as Sendgrid, Postmarkapp and Mailjet.
They have APIs and libraries for most programming languages, but in your case you just need to configure the SMTP server they rovide in your email client and you're good to go. They help you not get into the spam folder of your recipients, and help make sure you don't get flagged as a spammer
With most of them you should get some prettty powerfull analytics as well, which is a nice bonus.
