piolhomvp on "[Plugin: MailPoet Newsletters] Is it works in localhost"

Hello, I'm using the wordpress in localhost to do my website and after send to a server and get online. All plugins that I use works well even in localhost, for exemplo the chat plugin that needs inteet connection. But the mailpoet plugin is not sending emails. The subscribe widget is working well, when I put some email it goes to the list. But when I try to send a email to the list, the email doesn't go. Could you help me please? Thanks!
