- The Data validation feature isn't included in the standard Qualifio package. It has some additional, volume-based invoicing. For more information or to receive a quote, get in touch with your Customer Success Manager or send us an email.
How does the Postal Address validation work?
Postal address validation is done through a combination of algorithms and data sources, including national postal services, geolocation data, and other authoritative address registries. When an address is entered, the tool parses the input, standardises the format to a consistent structure, and checks for any discrepancies or errors. This process involves correcting common misspellings, updating outdated information, and validating the address against known postal records. The end result is a cleaned, verified address that is formatted according to postal standards.
If you use the international postal address validation, you must place the zipcode and city field before the rest of the address. (This is not necessary for France or Belgium).
How does Email validation work?
From the very first character entered in the email field, a series of suggestions with the format first name + last name is offered, displaying the most commonly observed combinations. This list becomes more refined as the user continues typing. (Prerequisite: The first name and last name fields must be present and completed before the email field.)
Similarly, we then offer a suggestion of domain names sorted by popularity and then alphabetically. The list will become more refined as the user continues typing.
We ensure that the domain name is correctly configured and properly associated with an email server. Specifically, we check for the presence of MX (Mail Exchanger) records in the domain's DNS zone (MX lookup).
The final step involves ensuring that the user (the local part) actually exists within the domain. In other words, does "johndoes" really exist at "gmail.com" (for the address johndoe@gmail.com)?
To do this, we send a request to the mail server and interpret its response.
We also detect the presence of disposable emails (like yopmail.fr) or email addresses that are likely to be spam traps.
How does the Mobile Phone validation work?
Mobile phone validation is done through a HLR lookup. A HLR lookup provides information about the telephone number including if the telephone number exists. A HLR lookup provides information about a telephone number, NOT a telephone user and can not provide any identifiable information about a human user.
The syntax of the Phone number, once verified is: +32457554125, where +32 is the country indicator. This cannot be changed.
Frequent questions about data validation
What are the main errors resulting from an invalid email message?
- The mailbox doesn't exist
- The mailbox has been disabled
- The mailbox is full
- There is a syntax problem
- The domain leads to unroutable IP addresses, marked as invalid
- The domain is unreachable
- The domain is considered as spam trap
- It's a role account (eg: support@, info@, etc.)
- The domain is known as disposable
- The email contains profanity
When is the validation performed?
The validation is performed when the focus exits the field. This means once the user clicks outside of the field or tries to directly after filling the field tries to submit the form.
Is it possible to only validate postal code and city?
No, today the full address must be validated.
Does the feature have to be activated on all forms or only a selection is possible?
You can decide at campaign or master form level to activate or not the feature.
Will I be notified if I'm nearing my limit of validation?
Yes, you will be notified at around 80% of the consumption.
What happens if I don't have any more credits to verify emails (or other items)?
The form submissions will be blocked.
If a user tries to validate their work email and then their personal email in the same participation, is that counted as 1 or 2 credits?
It's counted as 1 credit in the suggestion phase. If the user goes “out-of-focus” of the field or tries to submit for 2 different email addresses, it will be counted as 2 credits.
If I have a SSO, will the fields be validated if prefilled?
If they are hidden in the form, they won't be validated, nor will a credit be used.
What happens if I have paid for 100.000 emails validation but use just 95.000 of them, do I lose the rest?
Credits cannot be postponed.
