Engagement Tracking

Why It Matters

Reply rate is the gold standard for cold email, but it’s a lagging indicator. Open and click tracking give you earlier signals — you can tell whether prospects are seeing your emails and engaging with your links before they respond. This helps you iterate on subject lines, CTAs, and sending cadence faster.

Kit defaults tracking to off because deliverability matters more than vanity metrics in cold outreach. Enable it when you need engagement data and understand the trade-offs.

How It Works

When you enable tracking on a campaign, Kit converts outgoing emails from plain text to HTML:

Tracking Type	Mechanism	What It Detects
Open tracking	Embeds a 1x1 invisible pixel	When a recipient’s email client loads images
Click tracking	Rewrites links through a redirect	When a recipient clicks a link in the email

Recipients see a plain-looking email — no visual difference from plain text. The HTML wrapper adds structure but no styling or formatting changes.

Both tracking types are independent — you can enable one without the other.

Enabling Tracking

1. Open a campaign and click Edit
2. Scroll to the Engagement tracking section
3. Check Track email opens, Track link clicks, or both
4. Save the campaign

Changes apply to future messages only. Already-sent emails are not affected.

The campaign show page displays a tracking summary in the configuration section showing which types are active.

Accuracy Limitations

Open tracking has known reliability issues:

Factor	Impact
Apple Mail Privacy Protection	~50% of email users. Apple pre-fetches all images, inflating open counts with false positives.
Gmail image proxy	Gmail caches and serves images through its own proxy. First open is detected, but the user’s IP is Google’s, not the recipient’s.
Image blocking	Some corporate email clients block images by default. Opens go undetected until the recipient manually loads images.
Privacy extensions	Browser-based email clients with tracking blockers suppress pixel loading entirely.

Click tracking is more reliable — link redirects work regardless of image settings or privacy features.

Recommendation: Most senders enable click tracking only. Add open tracking if you need directional data on subject line performance, but don’t rely on open rates as a precise metric.

Reading Campaign Stats

When tracking is enabled and at least one message has been sent, the campaign show page displays an engagement row with up to three cards:

• Open rate — Percentage of sent messages opened at least once (only shown when open tracking is enabled)
• Click rate — Percentage of sent messages with at least one click (only shown when click tracking is enabled)
• Reply rate — Percentage of sent messages that received a reply (always shown)

Sub-text shows absolute numbers (e.g., “12 of 45 opened”) for context when sample sizes are small.

If tracking is active but no engagement has been recorded yet, a hint explains that data may take 24-48 hours to appear.

Reading Per-Message Engagement

On the messages list, sent messages with engagement show small icons next to the status badge:

• Eye icon (violet) — Message was opened. Hover for the count (“Opened 3 times”).
• Link icon (sky blue) — A link was clicked. Hover for the count.

On the message detail page, an Engagement card in the sidebar shows:

• Opens and clicks — Total counts with color-coded numbers
• First opened / First clicked — Timestamps showing when the prospect first engaged
• Event timeline — The 10 most recent events with type, clicked URL (for clicks), and relative timestamp. If there are more than 10 events, a note shows the total count.

The engagement card appears for any sent message where tracking was enabled on the campaign, even if zero events have been recorded (showing “Tracking is active” as an empty state).

Custom Tracking Domains

By default, tracking pixel and redirect URLs use your Kit account’s domain. For better deliverability, configure a custom tracking domain so these URLs match your sending domain.

1. Go to Account Settings > Custom Domains
2. Click Add Domain and select Outreach Tracking as the type
3. Enter your domain (e.g., t.yourcompany.com or mail.yourcompany.com)
4. Add the DNS record and wait for verification

Once active, all tracking URLs in outgoing emails use your custom domain instead of Kit’s default. See Custom Domains for DNS setup details.

The Outreach Tracking domain type requires an active Outreach addon subscription.

Deliverability Considerations

Tracking adds content to your emails that spam filters can detect:

Concern	Mitigation
Tracking pixels flagged as bulk mail	Use a custom tracking domain matching your sending domain
Link rewriting looks suspicious	Custom tracking domain makes redirect URLs appear first-party
HTML emails vs plain text	Kit’s HTML is minimal — no tables, no CSS, no images (except the 1px pixel)
Gmail cold email filtering	Google’s August 2024 update penalizes tracking pixels in cold outreach more aggressively

For maximum deliverability on cold campaigns, consider leaving tracking off and relying on reply rate as your primary metric. Enable tracking selectively on warm campaigns or when you need to diagnose low reply rates.

Quick Checklist

• Decide which tracking types you need (click-only is the safe default)
• Enable tracking on your campaign’s edit page
• Set up a custom tracking domain for best deliverability
• Monitor engagement stats on the campaign show page
• Review per-message engagement on the message detail page
• Don’t over-index on open rates — they’re directional, not precise
