Don't send emails

Hi all
I’m a new customer,
I istalled wordpress by “One-Click Installs” and 2 plugin awpcpc and contact coldform, both don’t send email, why ?

No conflict and both function

ps sorry for my english
news, with contact coldform sends but with a delay of about 20 minutes

Is the email for awpcpc sending from a address or something else?

Also have you asked here:

ok solved, the problem was because I used an email gmail for send
