Flexa Unsubscribe

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_KEY in wp-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. The Unsubscribes screen also accepts CSV import for bulk-adding opt-out records (skip-on-duplicate).
• 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.

A “Documentation” link is also added to the plugin row on the Plugins screen for one-click access from inside WordPress.
