Description

Blockrush Coupon Code Dispenser creates configurable email forms that send coupon or promotional codes to visitor-supplied email addresses.

Features include:

  • Any number of independently configured coupon products.
  • Any number of available Unique Coupon Codes, each delivered once.
  • Optional Repeat Coupon Codes that rotate continuously in their configured order.
  • Independent enable or disable controls for unique and repeating code sources.
  • Collision-resistant [brccd_coupon title="Product Name"] shortcode.
  • Conditional legacy [coupon title="Product Name"] compatibility when another plugin has not registered that shortcode.
  • Configurable success, duplicate, unavailable, and rate-limit messages.
  • Custom HTML email and out-of-codes templates.
  • Last Test Info with an expandable email and non-secret server diagnostic report.
  • Hourly and daily limits that cover both code and out-of-codes email.
  • Optional newsletter consent checkbox.
  • Optional Google reCAPTCHA verification, disabled by default.
  • WordPress personal-data export and erasure integration.
  • Confirmed Delete All Data and Factory Reset controls.

Email is delivered through WordPress using wp_mail(). Configure delivery through your host or a maintained WordPress SMTP plugin.

Privacy

When a visitor requests a code, the plugin stores their email address, a keyed one-way email hash, the assigned coupon code, whether it came from the unique or repeating source, delivery timestamps, and optional newsletter consent in the site’s WordPress database. This data is available to WordPress personal-data export and erasure tools. Site owners are responsible for choosing and disclosing an appropriate retention period.

To enforce delivery limits, the plugin stores keyed hashes of the submitted email and IP address, the attempt result, and the attempt time for up to seven days. It does not store the raw IP address. These records are included in personal-data export and erasure handling.

When an administrator sends a test email, the plugin keeps only the latest test diagnostic for that coupon product. It includes the test recipient, effective From address and name, subject, date and result, mail transport settings, and non-secret server version details. SMTP passwords, API keys, and authentication credentials are not collected. The record is replaced by the next test and removed when its product or plugin data is deleted.

Email is passed to WordPress through wp_mail(). Depending on the site’s mail configuration, the recipient address and message may be transmitted to the hosting provider or a separately configured email service.

Google reCAPTCHA is disabled by default. When enabled, the visitor response and IP address are sent to Google and Google’s script is loaded in the visitor’s browser. Site owners should disclose and obtain any consent required for their jurisdiction.

External services

This plugin can use Google reCAPTCHA only when a site administrator enables it for a product and saves valid reCAPTCHA keys.

The visitor’s browser loads https://www.google.com/recaptcha/api.js. On form submission, the plugin sends the reCAPTCHA response token and the visitor IP address to https://www.google.com/recaptcha/api/siteverify to determine whether Google accepts the request as human. No data is sent to Google by this plugin while reCAPTCHA is disabled.

Google provides this service under its Privacy Policy (https://policies.google.com/privacy) and Terms of Service (https://policies.google.com/terms).

Will deactivating the plugin remove data?

No. Deactivation does not remove data. Optional uninstall cleanup can be enabled in the plugin settings.

How is email sent?

The plugin uses WordPress wp_mail(), allowing the site owner to choose and maintain their mail transport.

What happens when both code sources are enabled?

Available Unique Coupon Codes are delivered first. When unique inventory is empty, Repeat Coupon Codes become the fallback and rotate from the last code back to the first.

How can I make coupon codes easier to read and enter?

The plugin delivers codes exactly as entered, so use a readable format when creating them:

  • Avoid characters that are easily confused, especially O and 0, I, l, and 1, S and 5, B and 8, and Z and 2.
  • Prefer uppercase letters and numbers with a consistent length.
  • Separate longer codes into short groups with hyphens, such as SAVE-7K9M, instead of one long unbroken string.
  • Avoid spaces and punctuation that may be dropped, wrapped, or changed by email clients.
  • Keep codes reasonably short and test both copy-and-paste and manual entry on mobile devices.
  • Do not include customer names, email addresses, or other personal information in a code.

Does the plugin confirm that a visitor owns the email address?

No. The form validates the address format and sends the code to that address, but it does not run a separate ownership-verification step.

Where can I get support?
