Flexa Unsubscribe adds a complete unsubscribe workflow to every email WordPress sends, with a fully-branded admin UI for managing opt-outs, analytics, and the public unsubscribe page.
- Auto-appends a secure unsubscribe button to outgoing single-recipient emails. Tokens are HMAC-signed using the
AUTH_KEYinwp-config.php, so no database lookup is needed to verify a link. - Blocks outbound mail to unsubscribed addresses before it reaches the mail server. Blocked attempts are logged to a dedicated audit table.
- Honours an exclude-keywords list (default:
Order, Password, Invoice) so transactional mail never gets an unsubscribe link and never gets blocked. - Re-subscribe URL is supported as a first-class action — the plugin can tell opt-outs from opt-backs.
- Customisable public page — every color, font, and string on the unsubscribe/re-subscribe templates is editable from the admin with a live preview.
Admin UI
Starting with v3.0.0 the admin is a React single-page application with seven screens:
- Dashboard — stats cards + bar chart of unsubscribes over time + pie chart of top reasons.
- Unsubscribes / Blocked emails / Re-subscribed — paginated tables with sorting, per-row delete, and CSV export.
- Reasons — manage the dropdown options shown on the public unsubscribe form; click-to-edit, / reorder.
- Settings — enable/disable auto-append + blocking, tune the exclude-keywords list.
- Appearance — 19 tokens (colors, typography, copy) across three tabs with a live preview panel.
All screens are powered by a REST API under /wp-json/flexa-unsubscribe/v1/, so external integrations can plug in too.
Source code for compiled JavaScript and CSS
The plugin ships with minified/compiled JavaScript and CSS in assets/dist/. The human-readable source code for these assets is publicly available and maintained at:
https://github.com/flexatech/flexa-unsubscribe
Source lives in the apps/admin (admin UI) and apps/frontend (product page UI) directories. Build tools used: pnpm, Vite, React, TypeScript. To build from source: clone the repository, run pnpm install from the plugin root, then build the admin and frontend apps (see the repository README for exact commands). This allows the code to be reviewed, studied, and forked.

FAQ.KG
-
Do I need to change anything in my existing email sending code?
-
No. The plugin hooks
wp_mailwith standard WordPress filters. Any plugin or theme that sends mail viawp_mailis covered automatically. -
What happens if I rotate `AUTH_KEY`?
-
Every in-flight unsubscribe/resubscribe link becomes invalid, because the HMAC key is
AUTH_KEY. New links issued after rotation work normally. Existing records in the database are unaffected. -
How are blocked emails different from unsubscribed addresses?
-
Unsubscribes is the list of addresses that opted out.
Blocked emailsis the audit log of outgoing sends that were stopped because they targeted an unsubscribed address. One unsubscribe can cause many blocked-email entries over time. -
No — CSV exports contain email addresses. Treat them as PII. The download link is nonce-protected so it’s not trivially shareable across sessions.

Өзгөртүүлөр
3.0.2
- Security: Sanitize
$_GET['email']and$_GET['token']at the read site in the public unsubscribe/resubscribe handler (sanitize_email/sanitize_text_field+wp_unslash), with a documentedphpcs:disable WordPress.Security.NonceVerification.Recommendedsince the HMAC token is the CSRF protection layer for these public links. - Compatibility: Replace inline
<style>and<script>blocks intemplates/unsubscribe-page.phpandtemplates/resubscribe-page.phpwithwp_register_style/wp_enqueue_style/wp_add_inline_style(and the script equivalents), so the public templates pass the WP.org Plugin Check enqueue rule. - Docs: Fix the source-code repository URL in
readme.txt.
3.0.0
- Complete admin rewrite. The seven admin pages are now a React single-page app (Vite + TypeScript + shadcn/ui + Tailwind v4) instead of individual PHP-rendered screens.
- New: REST API under
/wp-json/flexa-unsubscribe/v1/covering unsubscribes, blocked emails, re-subscribes, reasons, settings, appearance, and analytics. Every admin screen consumes this API. - New: Dashboard with time-series and reasons charts (recharts).
- New: Live preview panel on the Appearance screen — see your colors, fonts, and copy applied to a replica of the public unsubscribe page while you edit.
- New: Client-side search + server-side sort + server-side pagination on every list screen.
- New: URL-synced table state (
?page=2&sort=email&order=descbookmarkable) on every list screen. - Security: CSV export
admin-post.phphandlers now verify nonces viacheck_admin_referer(). - Change: Admin menu label is “Unsubscribe” (same as pre-2.x) and sits at menu position 60. Slug changed from
flexa-sutoflexa-unsubscribe— legacy admin bookmarks will 404. - Change: Removed the
flexa_get_analytics_dataAJAX endpoint, superseded by the REST/analytics/*routes. - Requires PHP 7.4 (was previously unspecified; the plugin now declares the floor).
