Should you track opens in cold outreach?

Whether to track opens in cold email involves tradeoffs between data and deliverability.

Arguments for tracking:

• Provides visibility into subject line effectiveness
• Indicates whether messages are seen at all
• Can trigger follow-up timing in some workflows
• Historical comparison across campaigns

Arguments against tracking:

• Deliverability impact: Tracking pixels can trigger filtering
• Reliability issues: Apple MPP makes data inaccurate
• Privacy concerns: Tracking without disclosure raises ethical questions
• Minimal actionability: Open data rarely changes strategy significantly

Practical considerations:

• Open rates are directional at best
• Reply rates are more meaningful for cold email
• Maximum deliverability requires minimal tracking
• Cold email already faces filtering challenges

Recommended approach:

• Consider disabling open tracking for highest deliverability
• If tracking, use custom tracking domain (not shared)
• Don't make decisions based solely on open data
• Focus measurement on replies and business outcomes
