Traffic ticket response sent within the 30 days but will arrive after the 30 days

This is a really stupid problem of entirely my own making, I'm just wondering if someone else here has dealt with the same thing.

I got a traffic ticket last month, thought I had a longer time to respond to it, and today finally got around to checking and discovered that a) I only had 30 days to respond, b) day 30 is today, and c) for some incomprehensible reason there's no online portal to respond (save for like four counties, and Baltimore county isn't one of them).

Since it's a Sunday I took it to UPS to send it off to the district court, but obviously it won't arrive until probably Wednesday. I asked for a trial, but I'm wondering if this will be accepted given I mailed it within 30 days but it won't arrive within the 30 days. Anybody dealt with this before?
