What Zinn® Campaigns – Email & SMS Marketing for WooCommerce & More does
Zinn® Campaigns is the free plugin that links a WordPress site or WooCommerce store to Zinn® Campaigns, the email, SMS and WhatsApp marketing service. You press Connect, sign in to Zinn® or create an account, approve the site, and you come straight back to WordPress, connected. Your Zinn® Campaigns sign-up forms then appear on any page, as a block or a shortcode, with your own words and consent sentence. Every sign-up is confirmed by double opt-in before anyone is mailed. The Pro add-on shows those forms as popups, and it is free with any paid Zinn® Campaigns plan, with a 30-day trial.
Why it matters
Most marketing plugins keep your list inside WordPress and ask you to paste an API key into a settings field. This plugin uses a one-time approval instead (PKCE, the method apps use to sign you in safely), so you never see or paste a key. Sign-ups go straight to Zinn® Campaigns, where consent is recorded and confirmed by double opt-in, so your list stays clean and lawful.
What is in it
10 free features and 3 more in Pro, listed from the plugin itself, so this page changes when the plugin does.

Questions about Zinn® Campaigns – Email & SMS Marketing for WooCommerce & More
Is the plugin free?
Yes. The plugin is free. Pro is free too with any paid Zinn® Campaigns plan, and you can try it for 30 days. The emails, SMS and WhatsApp messages you send are part of your Zinn® Campaigns plan.
Is it on WordPress.org?
Not yet. Download it from this page. It updates itself from Zinn®, and each update is checked before it is installed.
What happens if my plan ends?
The free plugin keeps working. Pro features stop showing on your site and a notice explains why. Nothing is deleted, and choosing a paid plan brings Pro back at once.
Does it work with my other plugins?
It works on any WordPress site, with or without WooCommerce. It recognises Tranzly, Page Builder Sandwich, WPML, Polylang, Contact Form 7, WPForms, Gravity Forms, Fluent Forms, Elementor, bbPress, BuddyPress, wpForo, Dokan, WCFM, WC Vendors and MultiVendorX.
Updates
On a site we host, these plugins are configured to update themselves: they check with us and WordPress installs the new version for you, with the download verified against its published checksum first. On a WordPress we do not host, there is nothing to configure and nothing phones home — come back to this page when you want the newest version, or watch the plugin's GitHub releases.
Need an older version?
Customers can download the newest release of each of the two previous major versions of every plugin in the Zinn Digital® app. It is there for a site that cannot run the current version yet — one still on an older WordPress or PHP — and for rolling back an update that caused a problem. When you can, install the current version.
