WSMS

WSMS is a WordPress plugin, formerly known as WP SMS, that adds SMS messaging capabilities to a site's dashboard. It connects to more than 300 SMS gateways worldwide, allowing site owners to send transactional notifications, marketing campaigns, and OTP-based two-factor authentication. The plugin also supports subscriber management and WooCommerce order alerts, and it is developed by VeronaLabs, an EU-based company registered in Estonia. WSMS has been maintained since 2012 under a GPLv3 open-source license.

The plugin includes modules for bulk SMS and MMS campaigns, scheduled and recurring messages, an SMS inbox for two-way conversations, and a REST API with hooks for custom integrations. It offers integrations with WordPress plugins such as Contact Form 7, Gravity Forms, Elementor Forms, Fluent Forms, Formidable Forms, Forminator, WooCommerce, Easy Digital Downloads, Ultimate Member, Paid Memberships Pro, BuddyPress, Fluent CRM, BookingPress, and WP Job Manager, as well as Zapier and webhooks. Additional capabilities include SMS-based login and two-factor authentication, password reset via SMS, abandoned cart recovery, checkout verification, URL shortening, reporting and analytics, and GDPR compliance tools.

WSMS is aimed at e-commerce stores, bloggers, membership sites, and service providers that need to communicate with their audience via SMS. It is packaged as a free core plugin with unlimited SMS sending, support for 200+ gateways, and standard support, alongside an All-in-One paid edition that adds 300+ gateways, advanced WooCommerce features, two-way messaging, SMS campaigns, and 2FA.
