No, you can't send mail without credentials.

Also, the credential has nothing to do with customer, The webmaster's credential or the organization's official credentials are used. The Customers just give their email to receive mail.

Hi,

 

Generally, you need  SMTP credentials to send email. In your case you can do in two ways:

1. Save credentials in webconfig or a configuration table. Then read that credentials and use it while sending email. 

2. Another using user credentials which is not recommended. Make sure, those users have rights to send email otherwise email fails. In this case, you need to get credentials from user login sessions or principle context then do query in DB to get password.
