Compatibility, licensing, and integrations

Check Subscribe Form’s technical requirements and distinguish included functionality from external services that need their own account, contract, or license.

Requirements and licensing

WordPress 6.0+ and PHP 8.0+. Code identified as GPL v2 or later retains the rights granted by that license. Support services and trademarks have separate terms.

Optional integrations

SMTP uses your chosen provider. Mailchimp requires an account. PLUGINFILES UPDATER needs a published catalog, a valid license, and configured backups.

Your installation, your responsibilities

The site operator determines the form’s purpose, consent language, and policies. Use maintained software, check compatibility, and test changes on a separate site.
