risk object

AtData risk fields leverage our historical database and the billions of email events we process each month to assess the input email's correlation with fraud.

score integer
A machine learning-based score from 0 to 100 that uses AtData's metadata to identify high-risk and fraudulent profiles. A score of 0 indicates low risk, while 100 indicates very high risk. Typical risk thresholds range from 70 to 80, depending on customer requirements.
Example: 50

tumbling_risk integer
A score from 0 to 3 indicating multiple variations of the same email address (e.g. jondoe@gmail.com and jon.doe+123@gmail.com are identical to gmail). Tumbling is evaluated across AtData's entire network, not just your own activity. Use this score to identify repeated signup patterns tied to the same mailbox.
Possible values:

0: no tumbling detected

1, 2 and 3: linear risk of tumbling

enumeration_risk integer
A score from 0 to 3 indicating multiple variations of the email address where the address varies by just numeric characters (e.g. jondoe1@gmail.com and jondoe2@gmail.com). Enumeration is evaluated across AtData's entire network, not just your own activity. Use this score to detect sequential account creation patterns that can indicate fraud.
Possible values:

0: no enumeration detected

1, 2 and 3: increasing enumeration prominence

query_id string
AtData's unique identifier for the response provided. Can be used with our Feedback API or for troubleshooting.
Example: 2744dd5d0acb475b81687d366fff4c48

ip object

Information related to the IP address associated with the email query.
⚠️ Provide an IP address to receive the ip object. ⚠️

routing_type string
The IP Routing Type (IPRT) specifies how the connection is routed through the Internet.
IP Routing Types:

fixed: The user is connecting through a fixed-line connection, such as cable, DSL, T1, and fiber. The user is likely to be at or near the location assigned to the IP.
aol, aolpop, aoldialup, aolproxy: The user is part of the AOL network. AtData can identify the user country in most cases. However, establishing the user location below country is not possible.
pop: The user is dialing into a regional ISP (Internet Service Provider) and is likely to be near the IP location.
satellite: The user is connecting to the Internet through a consumer satellite or a backbone satellite provider, where no information about the terrestrial connection is available. The user can be anywhere within the beam pattern of the satellite, which can span a continent or more.
cache proxy: The user is using a proxy connection, either through an Internet accelerator or a content distribution service. It is possible the user is located in a different country from the IP location.
international proxy: The user is connecting through a proxy (not an anonymizer) that routes traffic from multiple countries. It is possible the user is located in a different country from the IP location.
regional proxy: The user is connecting through a proxy (not an anonymizer) that routes traffic from multiple states within a single country. It is possible the user is located in a different state from the IP location.
corp proxy: The user is connecting through a proxy (not an anonymizer) that routes traffic through edge nodes, or nexus points for traffic entering and exiting a corporate network.
mobile gateway: The user is using a gateway to connect mobile devices to the public Internet. Many mobile operators, especially in Europe, serve more than one country and backhaul traffic through centralized network hubs. Therefore, it is possible the user is located in a different country from the IP location.

domain_risk_score integer

eam object

The origin of AtData's fraud solution is our Email Activity Metrics, which are used by all the leading antifraud solutions that evaluate email addresses. Through our broad client base, our extensive partner network and our 20-year history, AtData has the highest recognition rate of U.S. email addresses in the market, over 98%.

Forty percent of fraudsters use new email addresses. If AtData has not seen an email before or has only seen it recently, treat it as higher risk.

date_first_seen string
The date on which AtData first observed the email address. If the email address is new, the API returns now.
Example: 2016-08-09

longevity integer
A score from 0 to 3 indicating how long the email has been known, with 3 representing a longer period.
Possible values:

0: AtData has not encountered this email address before.

1: AtData first encountered this email within the last month.

2: AtData first encountered this email within the last year.

3: AtData first encountered this email over a year ago.

velocity integer
A score from 0 (no activity) to 10 (most active), reflecting the activity of the email address over the last 6 months.
Example: 10

popularity integer
A score from 0 (no sources in 12 months) to 10 (most sources) gauging the popularity of the email address over the last 12 months based on the number of sources from which AtData has received the address.
Example: 10

dam object

Similar to the EAM fields, the Domain Activity Metrics reflect activity at the domain level. Again, new or recent domains are more risky.

date_first_seen string
The date the domain first appeared in AtData's records.
Example: 2002-11-09

longevity integer
A score from 0 to 3 indicating when AtData first encountered the domain.
Example: 3

velocity integer
A score reflecting the activity of the domain over the last 6 months, from 0 (no activity) to 10 (most active).
Example: 10

popularity integer
A score gauging the popularity of the domain over the last 12 months based on the number of sources from which AtData has received the address, from 0 (no sources in 12 months) to 10 (most sources).
Example: 10

safe_to_send object

AtData's SafeToSend Email Verification service checks whether an address can receive email and whether sending to that address could hurt your ability to reach customer inboxes. It helps you identify invalid, misspelled, fake, and risky addresses, including spam traps.

If an email address is flagged returns an invalid status, reject it.

address string
Contains the input email address.
Example: email@example.com

status string
The summary status of the SafeToSend Email Verification result. These values describe deliverability and mailing risk.
Possible values:

safetosend: The email address passed all SafeToSend checks. It is safe to mail and is backed by AtData's deliverability guarantee.

valid: The email address passed most SafeToSend checks, but mailbox deliverability could not be confirmed. The address appears valid, but it may still bounce.

invalid: The email address is not safe to send to. It has incorrect syntax, an inactive domain, or a mailbox that does not exist. Do not send email to this address.

trap: The email address is valid, but mailing it could cause delivery issues, such as triggering spam filters. Examples include spam traps, honeypots, disposable addresses, and complainers. Do not send email to these addresses.

unknown: AtData could not complete the checks for this email address, so it carries a higher bounce risk.

corrected: This status applies only to files submitted through InstantData or the List API. The original address contained a syntax or spelling error, but AtData corrected it. Find the corrected address in your results file's "Valid Email" column.

status_code integer
A range from 5-999 will always be returned and describes the detailed results of the validation within the status categorization. For a full list of possible values, go to the SafeToSend Email Validation Status Codes page.
Example: 50

domain_type string
An optional field, indicates the type of the domain.
Possible values:

wireless: Domains for wireless devices that must not be sent unsolicited emails, as per the FCC.

role_account boolean
An optional field, role_account is returned when the email address is identified as a role-based account. A role-based account represents a business function or group (e.g. sales, info, support, marketing or customer service), such as info@abc.com.
Example: true

email_corrections array
An optional field, if your API key is configured for corrections, and the input address has a syntax or spelling error, we may suggest one or more corrected forms of the address. The returned value is a JSON array of possible corrected email addresses.
Example: ['email@gmail.com']
