In most, if not all jurisdictions, if it was sent first class US Mail, it is a presumption in law that it was delivered.
Do you have a source for this?

not even close to correct.
The US Mail is efficient but, run by humans, not infallible.
If it were, I would have never received my neighbor's (next door
and 2 doors over on another street) Visa bill and they would not have gotten my AMEX bill. Twice.
In this current jurisdiction, photo tickets, jury summons, etc., are mailed, then if there is no response they must send out a process server or other officer of the court to HAND DELIVER to someone of responsible age at that address.
The only way to get around the "hand to hand" is if the server goes back to court and wants an "alternate service" order because of someone dodging the process server. Then they can hang it on the door or a gate and call it good.
