- Questions vs statements
- Urgency words
Content:
- Layout (single vs multi-column)
- Image count and placement
- CTA button color/text
- Copy length
- Personalization depth
Timing:
- Send day
- Send time
- Timezone optimization
Statistical Significance
import scipy.stats as stats
def calculate_significance(control_opens, control_sent, variant_opens, variant_sent, confidence=0.95): """Calculate if A/B test result is significant."""
control_rate = control_opens / control_sent
variant_rate = variant_opens / variant_sent
# Pooled proportion
pooled = (control_opens + variant_opens) / (control_sent + variant_sent)
# Standard error
se = (pooled * (1 - pooled) * (1/control_sent + 1/variant_sent)) ** 0.5
# Z-score
z = (variant_rate - control_rate) / se
# P-value
p_value = 2 * (1 - stats.norm.cdf(abs(z)))
return {
'control_rate': control_rate,
'variant_rate': variant_rate,
'lift': (variant_rate - control_rate) / control_rate * 100,
'p_value': p_value,
'significant': p_value < (1 - confidence)
}

Send Time Optimization
def optimize_send_time(subscriber_data): """Analyze historical engagement to find optimal send times."""
engagement_by_hour = {}
for subscriber in subscriber_data:
local_time = convert_to_local(subscriber['open_time'],
subscriber['timezone'])
hour = local_time.hour
if hour not in engagement_by_hour:
engagement_by_hour[hour] = {'opens': 0, 'total': 0}
engagement_by_hour[hour]['opens'] += 1
engagement_by_hour[hour]['total'] += 1
# Calculate open rates by hour
for hour, data in engagement_by_hour.items():
data['rate'] = data['opens'] / data['total']
# Find best hours
sorted_hours = sorted(engagement_by_hour.items(),
key=lambda x: x[1]['rate'],
reverse=True)
return sorted_hours[:3] # Top 3 hours
List Hygiene
Engagement Scoring
-- Calculate subscriber engagement score SELECT subscriber_id, email, COUNT(CASE WHEN event_type = 'open' THEN 1 END) as opens_30d, COUNT(CASE WHEN event_type = 'click' THEN 1 END) as clicks_30d, MAX(event_date) as last_activity, CASE WHEN COUNT(CASE WHEN event_type = 'open' THEN 1 END) >= 5 THEN 'highly_engaged' WHEN COUNT(CASE WHEN event_type = 'open' THEN 1 END) >= 2 THEN 'engaged' WHEN COUNT(CASE WHEN event_type = 'open' THEN 1 END) >= 1 THEN 'somewhat_engaged' ELSE 'unengaged' END as engagement_tier FROM email_events WHERE event_date >= CURRENT_DATE - INTERVAL '30 days' GROUP BY subscriber_id, email;
Sunset Policy
Re-engagement Campaign: trigger: no_opens_60_days sequence: - Day 0: "We miss you" email - Day 7: "Last chance" with offer - Day 14: Final warning
action_after_sequence: if: no_engagement then: move_to_suppression_list
