Connect your registrar.
nmspc reads your domains from seven registrars and reminds you before anything expires.
Connect once and nmspc lists your domains with their expiry dates and auto-renew settings. You choose which ones to track; nmspc never renews, transfers or changes anything at your registrar.
Registrar not listed? CSV import works for domains at any registrar, and Missing yours? in Settings › Integrations is where to ask for the next one.
