DataTools’ Email Verification
The DataTools Email Verification service ensures that an email address actually exists in real-time without ever sending a message. From webforms to landing pages, mobile devices to Point-of-Sale systems (POS), DataTools’ email validation instantly validates the emails you collect.
So how does it work?
When an email is sent to the email verification service, 3 stages of verification occur. These are:
-
STEP 1
Determines if the email address follows the correct syntax and has the physical properties of an email address. Does it have a username and an @ symbol? Is the suffix a recognized email format, such as .com, .org, .net, .edu or .gov, etc?
-
STEP 2
Verifies the validity of the email domain (MX record) for the email address. This prioritises the delivery of email messages on behalf of the recipient’s domain to make sure the email domain can send and receive emails.
-
STEP 3
Connects directly to the email server to authenticate if the email address exists on the server. Instead of a simple ping, DataTools' Email Verification uses custom integrations developed alongside the ISP to communicate with the server via the preferred method. The technology works with all global ISPs and is constantly updated for changes in existing ISPs and new ISPs. This method is 97%+ accurate and averages 0.5 seconds per verification.
What type of information is returned?
The DataTools Email Verification service returns some useful status information about the email.
Primary Email Status
VALID - The email represents a real account / inbox available at the given domain.
INVALID - The email address is invalid. See the Secondary Status section below for more details.
ACCEPT ALL - These are domains that respond to every verification request in the affirmative, and therefore cannot be fully verified. It appears as if all of the emails are Valid at that domain, but the company actually has a firewall or another spam tool that may remove the email message or send a bounce message at a later time.
UNKNOWN - The email address looks good but the associated domain is not responding. This could be a temporary status for domains having intermittent issues or a permanent issue for dying domains.
Secondary Email Status
CONNECTED - Whether or not a valid email is connected to active online networks.
DISPOSABLE - Disposable addresses are created to be Valid only temporarily so their owners can sign up for promotions or services without using a primary address.
ROLE ADDRESS - Email address was created to message a function like sales@, support@, or postmaster@. Role address are email address that are set aside for functions, not people.
DataTools' Phone Number Verification
DataTools' Phone Number Verification service ensures that an Australian or New Zealand phone number is connected in real-time. Both landlines and mobile telephone numbers can be checked instantly.
Whereas similar services use a static list of phone numbers (like their phone book) that can become out of date, the DataTools phone verification service connects directly with the phone carriers to return the most accurate and up-to-date information.

What type of information is returned?
The DataTools Phone Number Verification service returns some useful information about the phone number’s connection status.
-
CONNECTED - The telephone number is connected.
-
DISCONNECTED - The telephone number is not connected.
-
INDETERMINATE - The telephone number returned an indeterminate status. The system could not reliably determine if the number is connected or disconnected.
