What do the codes in my Email Assurance Report mean?

Get started with DataValidation by linking a MailChimp, AWeber, SendGrid, Emma, MailUp or MailGun account or uploading an email list (via .csv) For every list (imported through ESP or uploaded to our system) you'll 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 to 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 lists' Address-by-Address Analysis.

This analysis contains Deliverability Codes which determine an email's Email Assurance Grade.Your Address-by-Address Analysis will provide you with the following information.

Address-by-Address Analysis

Your Always Free Email Assurance Report has already provided you with the number of emails that have each Email Assurance Grade. Now, with your Address-by-Address Analysis, you can dive deep into your email list to see exactly which emails have which grade, and why they were given that grade. Each address is also provided with Deliverability Codes that determine which grade they are given.

Deliverability Codes

Deliverability Codes are what make up an Email Assurance Grade, telling you which emails on your list are deliverable or not. These codes will provide information for each email based on their deliverability and email engagement status.

Deliverability Codes are provided on a scale of 1-4, with 1 being least deliverable and 4 being most deliverable.

Hard Bounces (H)

Historical Hard Bounce information will be provided for each email address within your list. This information provides you insight by showing you which emails have a hard bounce historyand how many sources we've received this information from.

A code of H1-H4 specifies an email's historical hard bounce information:

  • H4 No Historical Hard Bounce Info: This email has never hard bounced

  • H3 Single-sourced historical bounce: This address has bounced once; info provided from at least 1 source

  • H2 Double-sourced historical bounce: This address has bounced multiple times; info provided from at least 2 sources

  • H1 Multi-sourced historical bounce: This email has bounced multiple times; info provided from multiple sources

Opt-Outs (O)

Historical Opt-Outs determine the number of people on your email list that have a history of opting-out, or unsubscribing, from email lists. A subscriber's opt-out history is based on their overall email history.

A code of O1-O4 specifies an emails' historical opt-out information:

  • O4 No Historical Opt-Out Info: This email has never unsubscribed

  • O3 Single Sourced Historical Opt-Out: This email has unsubscribed in the past; info from at least 1 source

  • O2 Double Sourced Historical Opt-Out: This email has unsubscribed more than once in the past; from at least 2 sources

  • O1 Multi-Sourced Historical Opt-Out: This email frequently unsubscribes; info from multiple sources

Complainers (W)

Complainers are people who have a history of reporting email as spam. A historical complainer code will indicate whether a given email address on your list has a history of complaining about email or not.

A code of W1-W4 specifies an emails' historical complaint information:

  • W4 No Historical Complainer Info: has never marked email as SPAM

  • W3 Single Sourced Historical Complainer: This address has marked email as SPAM; info from at least 1 source

  • W2 Double Sourced Historical Complainer: This address has marked email as SPAM more than once, info from at least 2 sources

  • W1 Multi-Sourced Historical Complainer: This email frequently marks other email as spam, info from multiple sources

Spam-Traps (T)

Emails on your list that were once deliverable and Safe to deliver to, also have the potential of turning into a spam trap if left inactive for long periods of time. When an email address is set up for the sole purpose of detecting and catching spammers, it's usually not connected to a "real" inbox and is considered a spam trap.

A code of T1 or T4 specifies an emails' spam-trap information:

  • T4 We Have No Historical Trap Info - This email address has no history as being a spam trap. This is not a guarantee that an email isn't a spam trap, only a historical data point.

  • T1 Historical Spam Trap Info - This email address has been listed as a spam trap. It is possible that it may no longer be a spam trap.

Please Note: We no longer include spam trap data in determining our Email Assurance Grades (A+, A, B, D, F) - this information changes frequently and we cannot guarantee every instance to be accurate. This information will still be provided for each email in your Address-by-Address Analysis and can used for segmenting your list.

Deceased Individuals (D)

Sometimes old email lists contain addresses belonging to people who have passed away. This email address may still be listed as active or could turn into a spam trap sometime in the future. This code indicates whether an email address belongs to a person who is deceased or not.

A code of D4 or D1 specifies if a person with this email has Historical Deceased Information:

  • D4 No historical deceased information (the user is living)

  • D1 Historical deceased information (the user is deceased)

Please Note:We no longer include deceased individual's data in determining our Email Assurance Grades (A+, A, B, D, F) - this information changes frequently and we cannot guarantee every instance to be accurate.This information will still be provided for each email in your Address-by-Address Analysis and can used for segmenting your list.

Historical Opens (R)

This is a measure of the historical level of engagement based on the amount of deliverable mail sent to an address. This is a historical reference, and does not determine how likely one is to open your email.

A code of R4 or R1 specifies an address's history of email opens:

  • R4 A majority of emails delivered to the address historically resulted in an open

  • R3 Most of the emails delivered to the address historically resulted in an open

  • R2 Some of the emails delivered to the address historically resulted in an open

  • R1 Very few of the emails delivered to the address historically resulted in an open

  • R0 We have no historical data around email opens for this address

Historical Clicks (K)

This is a measure of the historical level of engagement based on the amount of deliverable mail sent to an address. This is a historical reference, and does not determinehow likely one is to click your email.

A code of K4 or K1 specifies an address's history of email clicks:

  • K4 A majority of emails delivered to the address historically resulted in a click

  • K3 Most of the emails delivered to the address historically resulted in a click

  • K2 Some of the emails delivered to the address historically resulted in a click

  • K1 Very few of the emails delivered to the address historically resulted in a click

  • K0 We have no historical data around email clicks for this address

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!

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.

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.

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.

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!
