Using phishing, spammers intend to extract sensitive personal and financial data about the recipient by disguising themselves to be a legitimate organization or an individual. For example, a spammer looking for your financial details will send you an email, that looks like a transactional email from a trusted service provider, asking for information such as passwords, user ids, bank account numbers, PIN numbers to list a few. ​Note that Zoho Mail will never ask you such information via email.
