Hello @juiceplus,
Firstly please make sure the email is not filtered to spam or junk folder of your email account. You can also try one of the following workarounds:
1. Try using another email address for From Email and Email to Send Submissions To options.
2. Perhaps your hosting does not have Sendmail enabled, which is required for mailing functions to work. Please contact your hosting provider and ask them to check this.
3. Alternatively, you can use an SMTP plugin, which will most probably resolve the problem.
You can try this plugin for example: https://ww.wp.xz.cn/plugins/wp-smtp/
Setting an external SMTP server, such as GMail should work. However, GMail requires authentication. Please find the necessary details for SMTP setup below.
Mailer: smtp
SMTP Authentication: yes
SMTP Security: SSL
SMTP Port: 465
SMTP Username: your gmail full address
SMTP Password: your gmail password
SMTP Host: smtp.gmail.com
