Free planning tool

See the reminder calendar before anyone gets an email.

Model due dates, time zones, weekends, and duplicate rules locally. The simulator never schedules a job or sends a message.

Release boundary: reminder email delivery is still certification-pending. This tool calculates a transparent local preview; it does not prove provider delivery, retries, suppression handling, or production scheduling.

Deterministic planning tool

Preview every reminder before delivery

Model timezone, business-day, and duplicate-prevention behavior without creating a job, sending an email, or storing client data.

Completion stops delivery

The production scheduler must cancel future jobs when every required item is accepted. This preview never creates those jobs.

Duplicate-safe plan

Rules that land on the same instant are combined before a provider ever sees them.

Reminder policy simulation ready. No reminder has been scheduled.
