Would you resend this email

[IHopeYouStepOnALegoPiece]

Sent out an friendly invoice reminder and the subject line (clients name and invoice number) has apparently disappeared looking at my Sent emails

Would you resend with ala subject line...if so would you not say anything or add an “apologies for the re send but no subject line so don’t want it to get lost”

Or just leave it

I'd resend it.

Definitely re send if you want your invoice paid!

I would just re-send it with the subject line and put something along those lines. Maybe instead of the 'don't want it to get lost' put 'but as I had missed out the subject line I was concerned it may get filtered out as junk mail' or something along those lines.
