What do the codes in my Email Assurance Report mean?

Get started with DataValidation by linking an ESP account or uploading an email list (via .csv) For every list (imported through ESP or uploaded to our system) you will receive an Always Free Email Assurance Report.

Always Free Email Assurance Report

This report card provides you the percentage of subscribers falling in each Email Assurance Grade category. This will help you make an informed purchase decision - we believe it should always be free to know the status of your email list, at any time. Your Free Email Assurance Report will provide you with the following information.

Email Assurance Grades

A+ Deliverable + Engagement Activity: The emails given a grade of A+ have been determined to be deliverable. They also have engagement history concerning email clicks and opens. These addresses are always Safe!

A Deliverable: The emails given a grade of A have been determined to be deliverable. These addresses are also Safe.

B Accepts-all: These emails have been deemed as "Accepts-All". A server that accepts all email means that the hostname has been set to accept any mail. This could also mean the email address in question may be a spam trap. This is commonly seen in business email addresses and in many cases, the server will accept all mail and then bounce it back to sender, which in turn hurts the sender's IP Reputation. We do not recommend sending to the "Accepts-All" category. All emails with a grade of B should be segmented (until later confirmed valid).

D Indeterminate: In checking for an email, we were not able to do anything. The email address seems to have a mail server that is running and accepting connections, but we are unable to connect. We do not recommend sending to the "Indeterminate" category. All emails with a grade of D should be segmented off your list.

F Undeliverable: The emails given a grade of F have been deemed as undeliverable and are therefore, invalid. These emails are unsafe to send to! These addresses should always be unsubscribed from your email database.

After reviewing your Always Free Email Assurance Report you'll be able to make an informed purchase decision. Upon purchase, you will have access to your list's Address-by-Address Analysis.

What People Are Saying

In less than two weeks we went from an 87% reputation to 98% with SendGrid. We have pleased the ISP gods thanks to your team!
— Mikhail Avady, IP SmartUP
I was a bit desperate yesterday after MailChimp blocked one of my uploaded lists. It is clear that DataValidation solved this very quickly. Thanks a lot!
— Yves Van Hee, Atradius
DataValidation saved my life! I had to migrate the newsletter campaigns from a self-programmed system to Zoho Campaigns, and I recognized, too late, that the dataset was horrible. Zoho blocked me during the first campaign.
— Hans-Henning Schulz, Deutscher Verlag für Gesundh
I LOVE your service. I’ve used the MailChimp integration, which works like a dream. I will be recommending your service to all my MailChimp clients as a “good practice” tool to add to their arsenal.
— Bridget Gilchrist, Tin Soldier Ltd.
Thanks very much for cleaning my list, the service works very well.

Super. I didn't expect the Mailchimp integration. It made everything painless.

The service I have received has been fantastic. Without any doubt the best online service I have ever had. Thank you!
— Andrés Gómez-Peña, IDB
On our first eNews to nearly 2,500 subscribers, we had only 5 bounce-backs and 7 unsubscribes. No way that would have been possible without your service! Thanks, DataValidation, for keeping us in compliance!
— Jodie Rogers, University of Oregon
You guys are awesome. I've been looking for a platform like this for 2 months to vet media contacts for my startup so I don't trash our domain in spam traps. This was the most effective tool I've found, and I'll be using it again on the consumer side as we develop a direct email marketing campaign.
— Jared Criscuolo, seededbox.com
Y’all have a great service with a nice clean, user friendly interface. Glad to be able to have multiple versions of our list to make use of. No doubt I’ll be using the services of your company again in the near future.

Very useful — helped us get over the hump with our first import of 6-year old data to MailChimp. Now running much more smoothly!
— Alex English, Tampa Bay Regional Transportation Authority (TBARTA)
Thanks Data Validation! It was easy to use and after I studied the definitions, I was able to re-sort my data for upload to MailChimp. In addition, your tips about sending emails to the Accepts All emails was extremely helpful!
— Jennifer Hoskins, PHR
It's awesome!! I was able to import the cleaned list of A's and B's into MailChimp no problem, whereas before cleaning with DV, MailChimp let me know a re-opt in would be required. I'm thrilled with this service!

We tried DataValidation on advice from a colleague. The service was easy to link to Mailchimp, and was extremely affordable.
— Jodie Rogers, University of Oregon
We are VERY satisfied. Your service has refreshed our stale mailing list and contributed to the surrealistic celebration of the Domestic Research Society's 10th anniversary - high in the Julian Alps!
— Alenka Pirman, Domestic Research Team
Your service has been outstanding, and I especially liked your LiveChat feature - very helpful!

We saved thousands of dollars that would have been spent on bounces and opt-outs by using DataValidation's cleaning tools. Now, we use their real-time protection so we never have a bad list again.
