Is it correct to write "Request to Help" as a subject line for an email?

I sent an email to the IT Dept. to ask for a technical help. I had googled some suggestions for a suitable subject line and found "Request to help...". I used it, but then I thought it was not be correct to use the preposition "to". Could it be possible?


They will definitely understand it, but “for help” is correct. As it’s an email subject, try something simple like "Help Request: printer jam" or similar.
