Trace a text

I apologise if this is in the wrong forum but if someone could please help me out, I would greatly appreciate it.

I got a couple of texts from the number 14011003 or some variation thereof. The from part just says - sent from protonmail.com and that's it.. The subject says test. It didn't have any other message other than that.

My question was whether that particular text could be traced? I know Protonmail doesn't store IP addresses. But is it still possible to trace the particular text? Also, in general, can you trace a text sent from an unknown number?

If someone could please help me out, I would so appreciate it.

Thanks in advance for your help and take care.
