= PRO Version =

The Newsletters LITE version has nearly all of the features that the PRO version has but it has some limitations.

* One mailing list.
* 500 max subscribers.
* Send up to 1000 emails per month.
* Mail Type: Local Server and SMTP. No API integration with our <a href="https://tribulant.com/docs/wordpress-mailing-list-plugin/10570/sending-apis/">mail service providers</a>.
* The "Drag & Drop Newsletter & Template Builder" cannot be used.
* Limited to Really Simple CAPTCHA and Google reCAPTCHA v2. The rest (reCAPTCHA v3, hCaptcha, Cloudflare Turnstile) cannot be used.
* No new custom dynamic fields can be added but you can edit current ones.
* No Resend button for emails and for the Send Manage Subscription Email link.
* No AI features.

These limits should be sufficient for a personal blogger or a small business.

To remove these limits, you can upgrade to the PRO version and submit your serial key inside the plugin.
Or, download, install, and activate the PRO version from our website under Downloads, and then add your serial key. This is the preferred method. After installing the PRO version, you can safely deactivate and delete the LITE version without losing your data.

In addition to the limits being removed, you will receive <a href="https://tribulant.com/support/">priority support</a> from <a href="https://tribulant.com">Tribulant</a>.
