[Eco Bounty] Subscription Form Fails with Complex but Valid Email Format

Summary

The email subscription form rejects syntactically valid but complex email addresses, returning HTTP status code 422 (Request failed with status code 422).

Steps to Reproduce

1. Visit https://depinscan.io/

2. Scroll to the footer section.

3. Enter the following valid but complex email address:

   a\"b(c)d,e:f;gi[j\\k]l@example.com 

4. Click the Submit button.

Actual Result

❌ The form displays an error:
Subscription failed: Request failed with status code 422

Expected Result

✅ The form should accept any RFC 5322–compliant email address (including valid special characters) or clearly specify invalid formats with a user-friendly validation message.

Impact

• Blocks legitimate subscriptions from users with special-character emails.

• Reduces newsletter reach.

• Indicates incomplete backend email format validation logic.
