Row-Level Security

All five tables are scoped to the current user's organization via get_user_org_id(). Any org member can select, insert, and update rows. Only admins (checked via is_admin()) can delete rows.

Dependencies

• crm -- contacts
• identity (transitive via crm) -- organizations, users, get_user_org_id(), is_admin(), set_updated_at()

Example Queries

Calculate open rate and click rate for a campaign:

SELECT
  c.name AS campaign,
  count(DISTINCT cs.id) AS total_sends,
  count(DISTINCT cs.id) FILTER (WHERE cs.status = 'delivered') AS delivered,
  count(DISTINCT ce.id) FILTER (WHERE ce.event_type = 'open') AS opens,
  count(DISTINCT ce.id) FILTER (WHERE ce.event_type = 'click') AS clicks,
  round(
    100.0 * count(DISTINCT ce.send_id) FILTER (WHERE ce.event_type = 'open')
    / nullif(count(DISTINCT cs.id) FILTER (WHERE cs.status = 'delivered'), 0),
    1
  ) AS open_rate_pct,
  round(
    100.0 * count(DISTINCT ce.send_id) FILTER (WHERE ce.event_type = 'click')
    / (( cs.id)  ( cs.status  ), ),
    
  )  click_rate_pct
 campaigns c
 campaign_sends cs  cs.campaign_id  c.id
  campaign_events ce  ce.send_id  cs.id
 c.id  
  c.id, c.name;

Show bounce rate by campaign:

SELECT
  c.name AS campaign,
  count(cs.id) AS total_sends,
  count(cs.id) FILTER (WHERE cs.status = 'bounced') AS bounced,
  round(
    100.0 * count(cs.id) FILTER (WHERE cs.status = 'bounced')
    / nullif(count(cs.id), 0),
    1
  ) AS bounce_rate_pct
FROM campaigns c
JOIN campaign_sends cs ON cs.campaign_id = c.id
WHERE c.status = 'sent'
GROUP BY c.id, c.name
ORDER BY bounce_rate_pct DESC;

List engagement events for a specific contact across all campaigns:

SELECT
  c.name AS campaign,
  ce.event_type,
  ce.url,
  ce.occurred_at
FROM campaign_events ce
JOIN campaign_sends cs ON cs.id = ce.send_id
JOIN campaigns c ON c.id = cs.campaign_id
WHERE cs.contact_id = '<contact_id>'
ORDER BY ce.occurred_at DESC;

Show segment sizes and how many campaigns each segment has been used in:

SELECT
  seg.name AS segment,
  seg.contact_count,
  count(DISTINCT cl.campaign_id) AS campaigns_used_in
FROM campaign_segments seg
LEFT JOIN campaign_lists cl ON cl.segment_id = seg.id
GROUP BY seg.id, seg.name, seg.contact_count
ORDER BY seg.contact_count DESC;

List campaigns with delivery summary (queued, sent, delivered, bounced, failed):

SELECT
  c.name AS campaign,
  c.status,
  c.sent_at,
  count(cs.id) FILTER (WHERE cs.status = 'queued') AS queued,
  count(cs.id) FILTER (WHERE cs.status = 'sent') AS sent,
  count(cs.id) FILTER (WHERE cs.status = 'delivered') AS delivered,
  count(cs.id) FILTER (WHERE cs.status = 'bounced') AS bounced,
  count(cs.id) FILTER (WHERE cs.status = 'failed') AS failed
FROM campaigns c
LEFT JOIN campaign_sends cs ON cs.campaign_id = c.id
GROUP BY c.id, c.name, c.status, c.sent_at
ORDER BY c.sent_at DESC NULLS LAST;

Find contacts who clicked a link in any campaign but never unsubscribed:

SELECT DISTINCT
  con.id,
  con.first_name,
  con.last_name,
  con.email
FROM contacts con
JOIN campaign_sends cs ON cs.contact_id = con.id
JOIN campaign_events ce ON ce.send_id = cs.id AND ce.event_type = 'click'
WHERE con.id NOT IN (
  SELECT cs2.contact_id
  FROM campaign_sends cs2
  JOIN campaign_events ce2 ON ce2.send_id = cs2.id AND ce2.event_type = 'unsubscribe'
)
ORDER BY con.last_name, con.first_name;
