Checks performed. Format Validation: verifies the email follows a valid RFC format. Temporary Email: detects disposable or throwaway email providers. Misspelled Domain: flags common domain typos like gmial.com. Spam Trap Check: identifies known spam trap addresses that harm deliverability. Domain Validation: confirms the domain exists and has valid MX records.
