Issue with email notifications could be caused by several reasons:
1. Your hosting provider is blocking all 3rd party settings, and only allowing their SMTP (or other) settings.
2. Your website has PHP version less than 7
3. The credentials are not correct
4. There's something else blocking the notifications from being sent.
5. If you're using Gmail, please make sure "Allow less secure apps" is enabled.
Please check these points, and let me know if you were able to resolve the issue. If you're still not able to resolve the issue, we'll need to remote into your website, and see what's going on.
Tried all configuration methods all show the error of mail not sent except wp mail it shows mail sent but on the other end, no mail was received.
