Email campaigns

Send to a list of users, track delivery, handle unsubscribes.

Send a one-off campaign or a recurring digest to a list of users. Tracks delivery, opens, clicks, and unsubscribes.

Time: ~30 min. Difficulty: Intermediate. Integrations: Resend.

Foundation prompt

Add an email campaign feature. Admins can compose a campaign (subject + body
in markdown), pick recipients (all users / users matching a filter), send.

Sends batch in chunks of 50 (Resend rate limits). Each send creates a log
row tracking: delivered, opened (via Resend webhook), clicked, bounced,
unsubscribed.

Unsubscribe link in every email; one-click unsubscribe. Unsubscribed users
never receive future campaigns.

Admin dashboard shows per-campaign stats (open rate, click rate, etc.).
