Weekly digests, monthly reports, daily summaries — automated.
Scheduled reports and automated email digests are high-value features that keep users engaged with the product without requiring them to log in. They require a cron job system and a transactional email integration. Getting the timing, personalization, and delivery right is the engineering challenge.
Need to send scheduled reports, weekly digests, or periodic emails to users — either as a product feature or as an operational report for the business
Scheduled reports require two components working together: a cron system that runs jobs on schedule, and an email delivery system that sends formatted content.
The cron system options:
Vercel Cron Jobs: Vercel supports scheduled functions via cron configuration in vercel.json. Functions run on a schedule; limitations include the 10-second timeout (or 5 minutes on Pro) and no state persistence between runs.
BullMQ scheduled jobs: A Redis-backed queue with scheduled job support. Jobs are enqueued to run at a future time or on a repeating schedule. Runs on a traditional server.
Inngest / Trigger.dev: Managed scheduled functions that handle the cron infrastructure.
The email delivery:
Resend or SendGrid send the actual email. The scheduled job queries the database for the report data, formats it as HTML or PDF, and sends it via the email API.
Personalization: Each user's report should show their own data. The query parameterized on the user's account. Batching is important at scale: don't run 1,000 separate database queries for 1,000 users — batch the data fetch and personalize per user.
Deliverability:
High-volume scheduled emails (weekly digests to all users) require attention to sending reputation: warm up sending domain, respect unsubscribes, monitor bounce rates, and don't send at 3 AM the user's local time.
Unsubscribe handling: CAN-SPAM (US) and GDPR require unsubscribe links in commercial emails. The unsubscribe must be honored immediately.

Questions, answered.
As often as users want, technically. Business decision: daily digests are valuable for high-activity products; weekly is the default for most SaaS; monthly is appropriate for lower-frequency workflows.
Yes — a user preference for report frequency is straightforward to add. Store the user's preference and schedule accordingly.
