I have just switched a domain and I am currently not receiving emails. But I can send.
Sorry to hear that! Can you provide me more information f.e name of your domain?
I will recommend you to contact official Webnode customer support via email email@example.com
If you are using some mail client f.e MS Outlook etc., you can check your settings with these tutorials.
Have a nice day
