Lifecycle mail is checked daily: trial reminders at 14:00 UTC, trial expiry at 14:30 UTC, and engagement (onboarding, usage, re-engagement) at 16:00 UTC. A send is skipped when the account has no email address, or when that template is disabled. Each rule below is also capped so the same condition does not send again on the next run. From address: noreply@memorycrystal.ai.

​
Trial reminders

Sent only while the subscription status is trialing, and only once per template during that trial. “Once per trial” means a send on or after seven days before trialEndsAt covers that trial. A later trial can send again.

​
Trial expiry

Template trial-expired is sent once, and only when all of these are true:
  • trialEndsAt is in the past
  • subscription status is not active
  • the trial ended within the last seven days
Older trials are not caught up later. A send on or after trialEndsAt covers that trial.

​
Onboarding

Template onboarding-nudge. An account older than 30 days is outside the window and is not caught up.

​
Usage warnings

Usage is active memories that are not knowledge-base chunks, divided by the memory allowance. Unlimited has no allowance, so it never receives these. Each template is sent at most once every 30 days. Crossing 95% sends the 95% template, not both, on that check.

​
Re-engagement

Template reengagement-7day. Idle longer than 60 days is not caught up.

​
Unsubscribe

Every engagement email—onboarding nudges, both usage warnings, and re-engagement—includes an Unsubscribe from these emails link and supports one-click unsubscribe in your mail app. The email link opens a page that asks you to Confirm unsubscribe. Confirm to stop these engagement emails. You can also turn them off or back on in dashboard Settings → Product tips and reminders by email. Account and billing emails such as trial reminders always send; this preference does not turn them off.
