Please refer to my reply on your other question.

Thank you

I thought I already accepted the answer so it will not notify you. Thank you.

I updated to v3.4.34 for guest email after checkout.. but it is not sending. Can you please tell me the specific files where I can make changes or you can please check it by your own?

Hello,

If you have updated, there is no need to know the files. We can't provide the list, I think it should be Shop controller. Please follow the update instructions from documentation.pdf

*I have tested the guest checkout again and it's working fine now.*

Thank you
