Common Questions
Most email tracking tools embed a tiny invisible pixel in your emails. When the recipient opens the email and loads images, the pixel notifies the tracking service. Link tracking works by routing clicks through tracking URLs.
Email tracking is legal in most jurisdictions for business communications. However, some regions like the EU under GDPR require disclosure. Most tools add tracking disclosures automatically when required.
Yes, recipients can block tracking by disabling image loading in their email client. Apple Mail Privacy Protection also blocks tracking pixels. This means tracking accuracy is typically 60-80% rather than 100%.
Most CRMs include basic email tracking, but dedicated tools often provide faster notifications, better accuracy, and more detailed analytics. The best approach is using a tracker that syncs with your CRM.
Mailtrack offers the best free tier with unlimited tracking. HubSpot Sales Hub and Streak also have generous free plans that include tracking plus additional CRM features.
