Title: Pay4All SMS Author: pay4all Published: October 26, 2026 Last modified: October 26, 2026 --- Search plugins ![](https://s.w.org/plugins/geopattern-icon/pay4all-sms.svg) # Pay4All SMS By [pay4all](https://profiles.wordpress.org/pay4all/) [Download](https://downloads.wordpress.org/plugin/pay4all-sms.1.0.3.zip) * [Details](https://wordpress.org/plugins/pay4all-sms/#description) * [Reviews](https://wordpress.org/plugins/pay4all-sms/#reviews) * [Installation](https://wordpress.org/plugins/pay4all-sms/#installation) * [Development](https://wordpress.org/plugins/pay4all-sms/#developers) [Support](https://wordpress.org/support/plugin/pay4all-sms/) ## Description Pay4All SMS turns your WordPress site into a self-service SMS marketing tool powered by [seven.io](https://www.seven.io/). * Public **signup shortcode** with a flag / international-format picker (intl-tel- input, 200+ countries). * Server-side **E.164 validation** and phone normalisation. * Optional **double opt-in** : the visitor confirms via a 6-digit code sent by SMS. * **Web unsubscribe** : every outbound SMS carries a token-based link to a confirmation page (auto-generated page or a shortcode on a WordPress page of your choice). * **STOP inbound** : hook seven.io Inbound-SMS to a webhook URL and the plugin marks « STOP », « STOPP », « ARRÊT », « BASTA » replies as unsubscribed automatically. * **Multilingual campaigns** : write the SMS body once per language (fr/de/it/en). Each contact receives the version matching their `lang`. * **Cost-safe batching** : the wp-cron tick sends a merchant-configured maximum number of SMS per minute. * **Delivery log** : one row per attempt with the provider id, cost, and delivery status. * **Pay4All Shop bridge** : one-click import of existing customers, plus an opt- in checkbox in the order form. ### External services This plugin connects to the **seven.io** SMS gateway API (`https://gateway.seven. io/api`), operated by seven communications GmbH & Co. KG, to send text messages. Nothing is sent until you enter your own seven.io API key under _Pay4All SMS > Settings_. What is sent, and when: * **Sending an SMS** (campaign, test SMS, double opt-in confirmation code) : the recipient’s phone number, the message text, the sender ID and an internal reference of the message. * **Estimating the cost of a campaign** (campaign editor) : the default country and one sample recipient phone number. * **Showing your account balance** (plugin dashboard) : no personal data, only your API key. If you configure them in your seven.io account, seven.io also calls your site back on the webhook URLs shown in the settings : delivery reports and inbound « STOP » replies. * seven.io terms of service : https://www.seven.io/en/company/terms/ * seven.io privacy policy : https://www.seven.io/en/company/privacy/ ### Privacy Contacts are stored in your WordPress database only : phone number, first name, language, country, subscription status, and the date and IP address of the consent. A log of sent messages (phone number, status, cost, beginning of the text) is kept as proof of sending. The plugin sends no data to Pay4All. Unsubscribed contacts are kept with a « stopped » status so they are never messaged again. ### Third-party libraries * **intl-tel-input 29.5.5** (MIT license) – phone field with country flags. Source code : https://github.com/jackocnr/intl-tel-input * Its bundled validation utilities are compiled from Google **libphonenumber** ( Apache License 2.0). Source code : https://github.com/google/libphonenumber The minified build files (`intlTelInputWithUtils.min.js`, `intlTelInput.min.css`, flag sprites) and the library’s LICENSE are bundled in `assets/public/vendor/intl- tel-input/` ; the human-readable sources are in the repositories above. ## Installation 1. Upload the `pay4all-sms` folder to `/wp-content/plugins/`. 2. Activate the plugin from the Plugins screen. 3. Sign up on [seven.io](https://www.seven.io/) and paste your API key + sender under _Pay4All SMS > Settings_. 4. Drop `[pay4all_sms_signup]` on the page where visitors should subscribe. 5. Create a campaign under _Pay4All SMS > Campaigns > New campaign_, write the message in each language, click « Send ». ## FAQ ### Do I need a paid seven.io plan? You need an API key + credit on seven.io. Pricing depends on the destination country; see seven.io for the current rate card. ### How do I let subscribers reply STOP? Rent a virtual inbound number in the seven.io dashboard and configure the Inbound- SMS webhook to POST to the URL shown under _Settings > Unsubscribe > STOP webhook_. Set a shared secret and paste it into the plugin settings. STOP-like keywords in every EU language are recognised automatically. ### Is web unsubscribe enough for GDPR? Every outbound SMS ships a token-based unsubscribe link, and every consent is logged with a timestamp. Consult your DPO for a full audit. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Pay4All SMS” is open source software.
