The message is lost and so is the contact. RadarAddress checks the email address of every submission of every Fluent 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. Phone numbers are verified too (one light check per number; the number that goes with the verification of the address uses none): valid, to check or invalid, with the number in international form next to it. A prefix menu next to the phone field is set to the country of the address and the form receives the number with the prefix in front; the number as typed is never rewritten. The Phone field of Fluent Forms Pro works on its own; with the free version, choose the text field that holds the phone number in Settings & Integrations RadarAddress. The Address field of Fluent Forms, free version included, works on its own: the street completes while the visitor types, postcode and city fill in, and on submission the address is verified against the national register. A different field, plain text fields or no address at all can be chosen for each form in Settings & Integrations RadarAddress. The address never blocks a submission and the fields of the visitor are never rewritten. Where the outcomes go: in a note on the entry, in three columns of the entry list and in the export, at the end of the notification emails (not the ones sent to the visitor), and in the SmartCodes `{radaraddress_email_outcome}`, `{radaraddress_email_original}`,`{ radaraddress_email_suggestion}`, `{radaraddress_outcome}`, `{radaraddress_address}`,`{ radaraddress_reason}`, `{radaraddress_phone_outcome}` and `{radaraddress_phone_international}`. **What you get** * Every email field of every form verified: syntax, domain that receives mail, disposable mailbox, role address (info@, office@…), unmistakable typo corrected. * The corrected address wherever the email is used: the Reply-To of the notifications and the notifications sent to the visitor. * Address autocomplete and correction on the Address field, or on the text fields you map, in the countries where the national address register is in service. * Verification of the address on submission, with the verified form and the reason, in a note on the entry. * Verification of the phone number on submission, with the number in international form, and a prefix menu next to the field. * Entries already received verified in bulk from the RadarAddress tab of the form: you choose which ones, in which order and how many. * The outcomes as columns of the entry list and in the export. * Verification precision from strict to maximum: how far RadarAddress goes to find an address written badly. * Typo correction level (1-3) for the email domain, and a «Did you mean …?» question on the field instead of a correction you did not choose. * Fail-open by design: if RadarAddress does not answer, the submission goes through as usual. * Data stays in the EU. Sources: the national address registers, published as open data. **How it works** 1. Create a free account on radaraddress.com (every month 500 light checks and 50 contact checks are free). 2. Create an API token in your personal area. 3. Fluent Forms RadarAddress: paste the token and press «Verify and save». The emails and the Address fields are verified from now on; for text fields, map them in Settings& Integrations RadarAddress of the form. One light check is used per email and per phone number 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, the phone number and, in the forms with an Address field or mapped fields, 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 ### External services This plugin connects to the RadarAddress API, a service run by RadarWave (the author of this plugin), to verify email addresses and phone numbers and to suggest and verify postal addresses. It does nothing until you paste your own API token in Fluent Forms RadarAddress. * **What is sent and when:** when a form is submitted, the email address typed in the email fields and the phone number typed in the phone fields (with the country of the form) are sent to be verified; in the forms with an Address field or mapped fields, the address typed (street, house number, postcode, city, province, country) is sent while the visitor types, to get suggestions, and on submission, to be verified. Your API token is sent with every request to identify your account. With each check the plugin also sends the address of the page that holds the form (without its query string) and the form and field it came from, so you can find it in your account’s log. The settings page also asks the API for your account’s remaining checks. * **Where:** https://www.radaraddress.com/api/v1/ (calls are made by your site’s server, or through the plugin’s own REST endpoint on your site: the token never reaches the browser). * **Terms of use:** https://www.radaraddress.com/en/terms * **Privacy policy:** https://www.radaraddress.com/en/privacy-policy ## Screenshots [⌊The entry: the RadarAddress note with the email corrected and the address verified.⌉⌊ The entry: the RadarAddress note with the email corrected and the address verified .⌉[ The entry: the RadarAddress note with the email corrected and the address verified.

Never for the address or the phone number. For the email only if you switch it on: then an address that cannot receive mail, or a role address, is refused with a message under the field, like any other validation error of Fluent Forms. ### Do I have to configure the fields? No: every email field of every form is verified, and so is the first Address field of the form. Only if the address is in text fields: Settings & Integrations RadarAddress of the form, five menus. ### Where do I see the outcome? In a note on the entry, in three columns of the entry list, in the export, and at the end of the notification emails you receive, as a short block. If you prefer a precise place, use the SmartCodes listed in the settings. ### Can I verify the entries I have already received? Yes: in Settings & Integrations RadarAddress of the form you choose which entries, in which order and how many. The outcomes are written in the entry; the email as it was written never changes. ### Does it change what the visitor wrote? The address fields, never: you receive what was typed and, next to it, the verified form. The email, only for an unmistakable typo in the domain and only if the option is on: the corrected address replaces the original where it is used (the reply address, the emails to the visitor), the original is kept in the notification and in the entry, and the visitor reads the corrected address in the confirmation message. ### How much does it cost? The plugin is free. One light check per email or phone number verified, one contact check per address verified. Every month the first 500 light checks and 50 contact checks are free. Beyond that, packs and monthly subscriptions on radaraddress.com. ### What if RadarAddress is down? The submission goes through as usual, with no message to the visitor; the notification says «not verified». ## Reviews There are no reviews for this plugin. ## Contributors & Developers “RadarAddress – Fake and Mistyped Email Check for Fluent Forms” is open source software.
