Emails are not Sending | WordPress.org

My wordpress does not send emails to gmail/yahoo

I have a wordpress site, which is “woo commerce” site . with “Fluent smtp” and ultimate member plugins for user registration. My site does not send emails to gmail and yahoo. But when i send a test email from fluent smtp it sends and its on the inbox. How ever when the site sends user activation/verification link. It’s not there in the email inbox or spam. But fluent smtp email log shows it was successful.

when i send email directly from hosting service provider. It sends. And its in the inbox.

when i use an email created to my domain name which is [email protected] . and register from this newly created mail. The site sends activation link to the inbox.

How can i fix this problem.

help me, thank you
