Q:

How to formatting a text with SimpleMailMessage?

My email content text is 
String text = "Hey, You are create a new Account! Best, MyTeam";

How can I format the text to:

Hey,

You are create a new Account!

Best, MyTeam

A:

SimpleMailMessage can only handle plain-text messages, so you need to embed explicit line-breaks in your String:
String text = "Hey,\n\nYou are create a new Account!\n\nBest, MyTeam";

A templating system such as velocity or freemarker may make this easier.
If you want to handle HTML messages, you need to use JavaMailSender and MimeMessagePreparator.
