Why do we do get this error?

An email address like test@test-com is not valid according to standard email formatting rules.

✅ Valid Email Format (RFC 5322 Standard)

A valid email address must follow this structure:

local-part@domain

Where:

• local-part: Can include letters, numbers, and some special characters.
• domain: Must include at least one dot (.) to separate the domain name and the top-level domain (TLD), like .com, .org, .net, etc.

❌ Why test@test-com is Invalid

• The domain part test-com is missing a dot.
• It should be something like test@test.com or test@sub.test.com.

✅ Valid Examples

• test@example.com
• user.name@company.co.uk
• admin@sub.domain.org
