SendGrid is a phenomenal company that does everything right when it comes to sending emails.

SendGrid provides an easy platform for any business to quickly and easily send a lot of emails, whether that email is transactional or marketing-related.

As great as they are, there are some things you could easily miss if you don’t know what you’re looking for.

What you are missing could be greatly hurting your delivery to mailbox providers, which in turn is potentially hurting your bottom line.

Internal Blocks At Mailbox Providers

There is a lot of “internal” blocking happening at the mailbox providers that you would not know about unless you painstakingly read through and monitor your suppression logs on SendGrid.

You could easily be spending several hours per day going through your suppression logs, looking for issues at mailbox providers. We’ve been there and done that! ;-)

Here are some examples of real issues that you could be missing by not monitoring your suppression logs:

This is an internal message from Microsoft telling you that either your individual IP or a whole section of the network that you are on is blocklisted by Microsoft.

This requires a ticket to be opened with Microsoft for mitigation and will require a lot of back and forth with them to get resolved. is not a major blocklist, but being listed by them is painful enough that it could cause you some reasonably painful delivery issues.

Spamrl has self-delisting, requiring a click on a link. Sometimes though, it does require a ticket with them.

Trend Micro is very important if you are sending any email to corporate domains, as many of them use Trend Micro to filter out spam before it hits their user’s mailboxes. These need to be taken care of rather quickly.

Trend Micro also has self-delisting, again sometimes requiring a ticket for resolution.

SORBS is not as important as it used to be, but it is still important enough to cause delivery pain to many mailbox providers. SORBS CAN be monitored using some external tools, but it can also be seen very quickly by monitoring suppression logs on SendGrid.

SORBS requires creating an account on their system and always requires a ticket to be opened for delisting.

This is another internal block by Microsoft, which is much more severe than the first one listed.

This requires a ticket to be opened with Microsoft for mitigation and will need a lot of back and forth with them to get resolved.

DrMX is another smaller but relatively painful blocklist to be listed on.

DrMX requires a ticket to be logged for delisting.

This is an internal block by AT&T. AT&T operates several mailbox provider domains.

AT&T requires an email to be sent to them, which opens a ticket.

This is just a tiny sample of all the potentially thousands of essential messages you could miss daily if you are not actively monitoring your SendGrid Suppression logs.

Some of these messages can be safely ignored, but knowing which to take action and which to ignore is where over 20 years of experience comes in. ;-)

Quick And Easy Overview Of Relevant Statistics

Another issue with SendGrid is having a quick and easy overview of your stats on something like a Google sheet where you can analyze the data to your heart’s content.

Something like this:

All the most important metrics, all automatically pulled into a Google Sheet for you so you can see all the data you could want in a quick and easy view.

As you have all this data in a sheet, you can now run any kind of analysis you want.

You can even graph the most important metrics to keep a close eye on!

Notifications Of Delivery Rate Below A Certain Percentage

Sometimes there is a rise in bounces or blocks which causes your delivery rate to drop lower than you would like, which in itself could be an indication that there may be a deeper lurking problem. Being notified as soon as this happens will help you (or us) to proactively investigate what caused the drop in your delivery rate and take action to correct any issues found.

How about being automatically notified if your delivery percentage drops below a certain number?!


This product and service is not a full-blown SaaS yet. We’re working on that as you read this.

Right now, it’s a handful of scripts running on a very secure group of servers, collecting the data, running the alerts, and updating the stats on Google Sheets, each individual per customer of course!

These servers are completely locked down and only my staff and I can even connect to them. The firewall blocks ALL incoming Internet connections except for my and my staff’s IPs. There is not even a web server running on it! We are NOT messing around with the security of your data!
