Hello @zitalyaar,
Could you please contact your hosting provider to inquire whether it is possible to access the email logs on the server? Additionally, we would appreciate it if you could provide an example, such as a video demonstrating how you tested the email sending function using the default theme. This will help us better understand the steps you followed and allow us to replicate the same process with the XStore theme.
Best regards,
Jack Richardson
