[Bug] Footer NewsLetter Subscribe Button Not working properly

[Queen-codes]

Description

When clicking on the subscribe button in the footer, nothing happens when no input is provided or when an invalid email is entered. Even when a valid email is entered, the page simply reloads without confirmation or action. This could lead to poor user experience.

Reproduction

1. Go to the newsletter section in the footer
2. Hit the subscribe button without entering any email
3. Try and enter an invalid email address and click the button, also enter a valid email address
4. If you try any of the steps in steps 3 and 4, you'll see the error - no feedback or action, just reloading of a page

Expectation

• An error message should appear when the user submits the form with an invalid or empty email.
• When a valid email is entered, a confirmation message or redirection (like in CC search) should occur, rather than reloading the page

Resolution

• [x] I would be interested in resolving this bug.
