Campaign doesn't send automatic email after someone subscribes trough form

Your software

My PHP version is: 8.1.27
My Database type and version is:10.11.7-MariaDB-cll-lve

Your problem
My problem is:

I’ve finally, finished the installation. I use hostinger and its email. I’ve created one form, added it to my wordpress, filled it, and it works. I received the email that I’ve added in the fields. The problem is: When I created campaign, and i added form first, then connected it with email I created to be sent immediately. I don’t receive any email. What did I do wrong? I even sent email from contact dashboard, and i received it, it’s working… It’s just not working when i set up campaign to send email instantly when someone subscribes trough the form on my website.

Please help, I am new. Thank you guys!
