Choose the Brevo API over HTTPS (works on hosts that block outbound SMTP ports) or the classic Brevo SMTP relay. Off until you switch it on, so installing this plugin never silently reroutes your mail. **Every form submission becomes a Brevo contact.** Brevo’s own plugin only syncs contacts from Brevo’s own sign-up forms — anything a visitor types into WPForms, Formidable, Contact Form 7 or Forminator never reaches your lists. Map a form to a Brevo list once, and from then on every submission is added automatically, with the right values in the right contact attributes, a record of the consent the visitor gave, and a log entry you can open when something looks wrong. **Disclaimer:** Rewind Form Bridge for Brevo is an independent, third-party plugin. It is not affiliated with, endorsed by, or an official partner of Brevo (Sendinblue SAS). “Brevo” and “Sendinblue” are trademarks of their respective owner. This plugin simply connects to the publicly documented Brevo API using an API key you create in your own Brevo account. #### What it does * **Brevo SMTP or Brevo API for site email.** One toggle, a sender address, and` wp_mail()` goes out through Brevo. Delivery failures are recorded and shown on the dashboard instead of vanishing. Optional and off by default. * **Maps any field to any attribute.** Pick a form field, pick a Brevo contact attribute, done. No paywall on the mapping UI. * **Type coercion that stops silent data loss.** Brevo accepts a request whose value does not match the attribute’s declared type — and then quietly drops the value. No error, no warning, an empty field. This plugin validates and converts every value against the attribute’s real type _before_ sending, so a date lands as a date and a number lands as a number. * **Phone numbers normalised to E.164.** Brevo rejects or mis-stores a bare local number. Set a default country and local numbers are converted to the international form Brevo expects. * **Consent capture, on by default.** A feed will not send anything unless a consent checkbox is mapped and ticked. You can switch that off per feed, and the screen tells you plainly what you are switching off. * **A real delivery log.** Every submission gets a row: status, HTTP code, Brevo’s error code translated into a sentence a human can act on, and the exact request and response bodies. Retry a failed delivery from the log. * **Failure alerts.** After a run of consecutive failures, an email goes out so a revoked API key does not silently swallow a month of sign-ups. * **Never calls the API behind your back.** No request is made on activation, on admin page loads, or before you save a key. Lists and attributes are cached and refreshed only when you ask. #### Supported form plugins * WPForms (Lite and Pro) * Formidable Forms (Lite and Pro) * Contact Form 7 * Forminator Each integration is written against that plugin’s own submission hook, so composite fields are handled properly: a WPForms, Formidable or Forminator Name field exposes its first, middle and last parts as separate mappable values, and Address fields expose street, city, state, postal code and country. The adapter layer is public— additional form plugins can be added by filtering `rbfb_adapters`. #### Your API key Brevo API keys are account-wide — Brevo does not offer scoped keys. The key is stored in the options table, shown in the dashboard as its last four characters only, and never included in a REST response, a log entry or an export. If you would rather keep it out of the database entirely, define it in `wp-config.php` and the field becomes read-only: ``` define( 'RBFB_API_KEY', 'your-key-here' ); ``` ### External Services This plugin connects to Brevo, a third-party email marketing and transactional email service, because sending your form submissions to Brevo is the entire purpose of the plugin. No request is ever made until you enter your own Brevo API key. **Brevo API** — https://api.brevo.com/v3 (service homepage: https://www.brevo.com/) What is sent, and when: * When you click “Test connection”: nothing but your API key, to GET /account, to confirm the key works and to read your account name. * When you open the field-mapping screen and ask to refresh: your API key, to GET /contacts/lists, `GET /contacts/folders` and `GET /contacts/attributes`, to read back the lists and contact attributes in your account. Results are cached locally for 15 minutes. * When you create a contact attribute from the mapping screen: the attribute name and type, to `POST /contacts/attributes/{category}/{name}`. * When a visitor submits a form you have mapped: the submitted email address, the form values you mapped to Brevo attributes, and the IDs of the lists you chose, to `POST /contacts`. * Only if you switch on “Site email”: your API key, to `GET /senders`, to read back the verified sender addresses on your Brevo account so you can pick one. * Only if you switch on “Site email” with the API transport: the recipients, subject and body of the emails your site sends via `wp_mail()`, to POST /smtp/email. **Brevo SMTP relay** — smtp-relay.brevo.com Only if you switch on “Site email” and choose the SMTP transport. Your SMTP login, SMTP key, and the recipients, subject and body of each outgoing email are sent to Brevo’s relay over an authenticated TLS connection. By using this plugin you are sending data to Brevo, and Brevo’s own terms govern that data: * Terms of Service: https://www.brevo.com/legal/termsofuse/ * Privacy Policy: https://www.brevo.com/legal/privacypolicy/ The plugin makes no other outbound request. It contacts no analytics service, no licensing server, and no CDN — fonts and scripts are all served from your own site. ### Privacy The plugin stores three tables in your own database: mapped feeds, a delivery log( submitted values, request and response bodies, capped at 64KB each), and a consent record (email address, the exact consent wording the visitor saw, the page URL and the visitor’s IP address). Consent records exist so you can prove a subscription was asked for, which is why nothing is deleted when you uninstall unless you first tick “Delete all plugin data when the plugin is uninstalled” on the Settings screen. Log entries can be cleared at any time from the Logs screen. ### Source Code The admin dashboard is a React application compiled with `@wordpress/scripts`. Everything in `assets/` is build output — `assets/admin.js`, its stylesheets, and the hashed font files in `assets/fonts/`. The complete, unminified source those are built from ships inside this plugin, in `src/`, including the original font files in `src/admin/fonts/`. Nothing has to be downloaded to inspect or rebuild it. To rebuild from the plugin folder: 1. `npm install` 2. `npm run build` That reads `src/admin/index.js` and rewrites `assets/`. No minified or obfuscated third-party code is bundled. React, ReactDOM, the JSX runtime and every `@wordpress/*` package are loaded from the copies WordPress core already ships, declared as script dependencies in assets/admin.asset.php. ### Credits * Poppins by Indian Type Foundry and Jonny Pinhorn, licensed under the SIL Open Font License 1.1 (https://scripts.sil.org/OFL) and self-hosted. * Portions of the React component kit are derived from Ninja Drive by Plugininja, licensed GPL-2.0-or-later. See `LICENSE.txt` in the plugin folder for the full list of bundled assets and their licences. ## Installation #### 1. Install the plugin From your WordPress admin, go to **Plugins Add New**, search for “Rewind Form Bridge for Brevo”, click **Install Now**, then **Activate**. To install the zip by hand instead: **Plugins Add New Upload Plugin**, choose the file, **Install Now**, then **Activate**. Or unzip it into /wp-content/plugins/ over FTP so the files land in /wp-content/plugins/rewind-form-bridge-for-brevo/, then activate it from the Plugins screen. You need WordPress 6.6 or newer and PHP 7.4 or newer. Nothing is sent to Brevo during installation or activation. #### 2. Get a Brevo API key 1. Sign in at https://app.brevo.com/ — a free account is enough. 2. Open https://app.brevo.com/settings/keys/api 3. Click **Generate a new API key**, name it something you will recognise later ( for example “WordPress”), and copy the value. It starts with `xkeysib-`. 4. Copy it now: Brevo shows the key once and never again. Brevo API keys are account-wide — Brevo offers no scoped or read-only keys, so this key can do anything your Brevo account can do. Treat it like a password. #### 3. Connect Go to **Brevo Bridge Connections**, paste the key, and click **Test connection . On success the screen shows your Brevo account name and the last four characters of the key; the key itself is never shown again, never returned by the REST API, and never written to the delivery log. Prefer to keep the key out of the database? Put this in `wp-config.php` instead, above the “That’s all, stop editing” line: ``` define( 'RBFB_API_KEY', 'xkeysib-your-key-here' ); ``` The field then shows as read-only and sourced from the constant. #### 4. Send your site’s email through Brevo (optional) Skip this if you only want contact syncing. 1. In Brevo, add and verify the address you want to send from, under **Senders, Domains& Dedicated IPs**. Brevo rejects mail from an unverified sender, so do this first. 2. Go to **Brevo Bridge Settings Email** and switch **Site email** on. 3. Choose a transport: 4. * **API (recommended)** — sends over HTTPS on port 443, which every host allows. Uses the API key you already saved. * **SMTP relay** — the classic route. You will also need your SMTP login and an SMTP key from https://app.brevo.com/settings/keys/smtp, and your host must allow outbound port 587, 465 or 2525. 5. Pick your verified sender address, and a reply-to address if it differs. 6. Click **Send test email** and confirm it arrives. Until you complete this step `wp_mail()` behaves exactly as it did before — installing the plugin does not silently reroute your site’s email. #### 5. Send form submissions to a Brevo list 1. Make sure the form plugin you use is active: WPForms, Formidable Forms, Contact Form 7 or Forminator. 2. Add a consent checkbox to your form if it does not have one — something like “ Yes, email me your newsletter”. You need it for step 5, and you need it to be able to show that each subscriber asked to be subscribed. 3. Go to **Brevo Bridge Mappings** and click **Add mapping**. 4. Choose the form plugin, then the form, then the Brevo list or lists the contact should join. 5. Choose the **consent field** — the checkbox from step 2. Nothing is sent for a submission where that box was left unticked. 6. Choose the **email field**. This is the only mapping that is required. 7. Map any other fields you want on the contact. Each row pairs one form field with one Brevo contact attribute, and the screen shows the type Brevo expects for that attribute so values are converted correctly instead of being silently dropped. Name and Address fields can be mapped whole or by part — first name and last name to separate attributes, for example. 8. If you map a phone or SMS attribute, set **Default country** under **Settings General** so local numbers are converted to the international form Brevo requires. 9. Save. #### 6. Check that it worked Submit the form on your site once, then open **Brevo Bridge Logs**. You should see a row with status **Success** and HTTP code 201 (contact created) or 204 (existing contact updated). Open the row to see the exact request that was sent and the exact response Brevo returned. If the row says **Failed**, the message column explains why in plain language, and **Retry** re-sends that submission once you have fixed the cause. If it says** Skipped**, the consent box was not ticked, or the contact already exists and this mapping is set not to update existing contacts. Optionally, set a **Failure alert email** under **Settings General** so you are told by email if deliveries start failing in a row. ## FAQ ### Do I need a paid Brevo account? No. A free Brevo account gives you an API key, and that is all this plugin needs. ### Which form plugins are supported? WPForms, Formidable Forms, Contact Form 7 and Forminator — free editions included. Each one is integrated through its own submission hook, so nothing depends on scraping` $_POST`. The adapter layer is a documented filter (`rbfb_adapters`), so more can be added without touching the core of the plugin. ### Why is my contact created but a field is empty? That is Brevo’s most confusing behaviour: if a value does not match the attribute’s declared type, Brevo accepts the request and silently drops the value. This plugin coerces and validates every value before sending specifically to prevent it, and the delivery log records any value it had to convert or reject. If you still see an empty field, open the log entry — the request body shows exactly what was sent. ### Why is my phone number rejected? Brevo requires a country code on SMS attributes. Set **Default country** on the Settings screen and local numbers will be converted for you. ### Are any features locked behind a payment? No. Everything described here works in this plugin, with no licence key, account or trial period. ### Does the plugin call Brevo when I am just clicking around the dashboard? No. Requests happen only when you test the connection, explicitly refresh the cached lists and attributes, create an attribute, or when a visitor actually submits a mapped form. ### Will installing this change how my site sends email? Not unless you tell it to. “Site email” is off by default; `wp_mail()` behaves exactly as it did until you switch the transport on yourself. ### Should I use the Brevo API or the Brevo SMTP relay? Prefer the API. It rides HTTPS on port 443, which every host allows, while many hosts block outbound 587 and 465 — and when they do, the symptom is simply that email stops, with no error anywhere. Choose the SMTP relay only if your Brevo account or hosting policy requires a real SMTP conversation. ### Do I still need a separate WP SMTP plugin? No. Switch on Site email, pick a verified Brevo sender, and this plugin takes over` wp_mail()` for the whole site. ### Can I use this only for SMTP, without mapping any forms? Yes, and the reverse is also true. The two features are independent: the site email transport works with no feeds configured, and contact sync works whether or not you route your site’s email through Brevo. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Rewind Form Bridge for Brevo” is open source software.
