The email sent to customers post ClassifAI plugin registration contains outdated information pertaining to the 'Requirements' section.

1. As per the GitHub readme, the minimum requirements are as follows:

• Minimum PHP version: 7.4+
• Minimum WordPress version: 5.7+

The email has the following:

• Minimum PHP version: 7+
• Minimum WordPress version: 5.0+

2. Now ClassifAI also provides features related to OpenAI. So would be great if add the reference of OpenAI in email content.
