RadarAddress checks AcyMailing subscribers for bad email addresses

This is a deliverability and address-quality check for AcyMailing subscribers. According to the listing, it labels addresses as valid, corrected, typo, unable to receive, disposable or role addresses, and can retain the original when it corrects a likely typo.

The problem exists because Joomla's core registration and user-management features can collect an email address and, where configured, require confirmation; they do not verify that a mailbox can receive mail, identify disposable addresses or correct gmial.com-style mistakes. AcyMailing handles newsletter subscribers and forms, but this listing adds an external address-checking service to that workflow. Sites otherwise use confirmation emails, bounce handling, manual cleanup or a separate validation service. A template override would only change the form or its presentation, not test the address.

• The add-on can process all subscribers or one list, run checks for new subscriptions and optionally unsubscribe addresses reported as unable to receive.
• It is free, but requires a free RadarAddress account and API token. The first 500 light checks each month are free; further checks use RadarAddress packs or subscriptions.
• It targets newsletter operators with existing AcyMailing lists, imports or signup forms. A site that does not use AcyMailing, or only needs email confirmation, has little reason to install it.

Before installing, note the stated requirements: AcyMailing 9 or later, Joomla 4, 5 or 6, and PHP 8.1. The directory shows Gianluca Sordiglioni as developer, two other extensions and no reviews, so the public track record visible there is limited. The listing does not give full service pricing, API limits, detailed checking rules, or migration and uninstall guidance. It also says processing is in the EU and data is not retained after a check; review the service's privacy and terms before sending subscriber data.
