The entry detail: the RadarAddress box with the email corrected and the address verified.
A visitor writes to you, you answer, and the reply bounces: the email was mistyped, or it was a throwaway address. The message is lost and so is the contact.
RadarAddress checks the email address of every submission of every Gravity Forms form, with nothing to configure beyond the API token: an unmistakable typo in the domain (gmial.com, hotmal.com…) is corrected and you receive the reply address that works, with the original kept; an address that cannot receive mail (a domain that does not exist, a disposable mailbox) is flagged, and refused with a message under the field only if you switch that on. The visitor who made a typo reads the corrected address in the confirmation message.
The Address field of Gravity Forms, in every license, is verified with nothing to configure either: the address completes and corrects itself while the visitor types, from the national address registers of 25 European countries, and is verified on submission. Forms that keep the address in text fields map them in the RadarAddress tab of the form settings. The visitor’s fields are never rewritten and nothing ever blocks the submission.
Where the outcomes go: in the entry (six RadarAddress fields, available as columns of the entry list, in searches and in the export, and in a box of the entry detail), at the end of the notification emails sent to you (not the ones whose recipient is a field of the form), and in the merge tags {radaraddress_email_outcome}, {radaraddress_email_original}, {radaraddress_email}, {radaraddress_outcome}, {radaraddress_address} and {radaraddress_reason} for whoever wants them in a precise place. Entries you already received can be verified from the entry list, with the bulk action «Verify with RadarAddress» on the entries you select.
What you get
How it works
One light check is used per email verified; one contact check per address verified (typing is free; a selection from the suggestions and the verification of the same address count once). For most sites the free checks of the month are all they need; beyond that, packs and monthly subscriptions on radaraddress.com.
Third-party service
This plugin sends the email address and the address typed in the form to the RadarAddress API (https://www.radaraddress.com) to get verification results and suggestions. Terms: https://www.radaraddress.com/en/terms — Privacy: https://www.radaraddress.com/en/privacy-policy.php
This plugin connects to the RadarAddress API, a service run by RadarWave (the author of this plugin), to verify email addresses and to suggest and verify postal addresses. It does nothing until you paste your own API token in Forms Settings RadarAddress.
