Missouri does not require a written notice before filing for non-payment, but a dated notice with the amount owed is still what the court and the tenant expect — and it is your proof. Balance, deadline and delivery record filled in from the tenant's ledger.
The reason changes the wording and the deadline. Pick the situation; the period on each card is Missouri's minimum — your lease can require more, never less.
RSMo §§ 535.020, 441.060RSMo §§ 535.020, 441.060Missouri requires no statutory notice before filing for non-payment (RSMo §§ 535.020, 441.060). A written notice is still standard practice and what judges expect to see.
A lease can lengthen the period. Whether it can shorten it depends on the state — Missouri's rule is above; when the lease is silent, the statutory period applies.
From the day after delivery, and the notice should state the deadline as a date. Where Missouri counts business or judicial days, weekends and court holidays are skipped.
You file the eviction in the local court. Filing before the notice period ends gets the case dismissed, so keep the delivery date.
Only if the lease agrees to electronic delivery; otherwise use hand delivery, mail or posting where Missouri permits it. The in-app notice emails the tenant and logs it, and prints for hand delivery.

Notice periods are Missouri's statutory minimums as of 2026, reviewed against Revised Statutes of Missouri, Chapter 535 (Landlord-Tenant Actions). General information for landlords, not legal advice; local rules — and the CARES Act 30-day notice for covered properties — can add requirements.
