Link Tracking: How to Track Transitions from WhatsApp to Email

In today's digital marketing landscape, businesses are increasingly using multiple channels to engage with their customers. WhatsApp, with over 2 billion users, has become a powerhouse for real-time conversations, while email remains the go-to for more detailed, nurturing communications. But what happens when a user clicks on a link in a WhatsApp message that leads to an email sign-up, newsletter subscription or email campaign? Tracking these transitions, where interactions start on WhatsApp and convert via email, is crucial for understanding customer journeys, optimising campaigns and measuring ROI.

Cross-channel tracking involves monitoring user behaviour across platforms such as WhatsApp and email in order to gain a comprehensive understanding of engagement. This enables marketers to accurately attribute conversions, such as when a WhatsApp prompt prompts a user to open an email or complete a form. According to industry insights, integrating WhatsApp with email can boost engagement rates by up to 30%, as it combines the immediacy of messaging with the depth of email content. However, bridging these channels seamlessly can be challenging, particularly since WhatsApp links don't natively support standard tracking methods such as UTM parameters in the same way that web URLs do. However, with the right methods and tools, these transitions can be effectively tracked.

This article explores methods for tracking link clicks from WhatsApp that lead to email-based actions. It covers best practices, available tools and step-by-step implementation. Mastering this can enhance your analytics and drive better results, whether you're a marketer at a small business or a large enterprise.

Understanding cross-channel transitions between WhatsApp and email.

In this context, a 'transition' refers to the handover from one channel to another. For example, a user receives a WhatsApp message containing a link to subscribe to an email newsletter. They click on the link, land on the sign-up page and complete the form, resulting in an email conversion. Tracking this conversion ensures that you know the WhatsApp message was the source and not another channel, such as organic search.

Why is this important? Customers don't interact in isolation; they switch channels based on convenience. WhatsApp is great for quick, conversational engagement (e.g. polls, images or chatbots), while email is better for long-form content such as guides or promotions. By tracking these transitions, you can gain valuable insights.

• Attribution: Which WhatsApp campaigns lead to email sign-ups or opens?
• Engagement metrics: Open and click-through rates (CTRs) and conversion funnels across channels.
• Optimisation: Identify drop-offs, such as users who click on WhatsApp links but then abandon the email form.

Data shows that users who engage with multiple channels are three times more likely to convert. However, without tracking, you risk misattributing success. Common scenarios include:

• Abandoned cart recovery: WhatsApp sends users a reminder, along with a link to an email containing a discount code.
• Lead nurturing: Use WhatsApp chats to create email onboarding sequences.
• Re-engagement: WhatsApp polls collect user preferences to inform personalised email campaigns.

Challenges include WhatsApp's focus on privacy, which limits direct tracking, and the need to handle data in accordance with regulations such as GDPR.

To visualise this, consider a user journey diagram. It begins with a WhatsApp notification, progresses to a link being clicked, moves on to an email interaction (e.g. opening or clicking), and concludes with a conversion such as a purchase confirmation.

Methods for tracking transitions

There are several proven methods of tracking these links that focus on attribution and analytics.

1. UTM parameters

UTM (Urchin Tracking Module) tags are the gold standard for tracking links. Add them to URLs in WhatsApp messages to collect source data using tools such as Google Analytics.

• How it works: Add parameters such as '?utm_source=whatsapp&utm_medium=messaging&utm_campaign=newsletter_signup' to your link. When the link is clicked, this data is passed to your landing page or email platform.
• For email transitions: if the link leads to an email-related action (e.g. a form that sends an email), set up goals in Analytics to track completions. Please note that WhatsApp links (wa.me) do not support UTMs directly, so redirects or shortened links should be used instead.
• Example: Original link: https://example.com/signup. Tagged link: https://example.com/signup?utm_source=whatsapp&utm_medium=chat&utm_campaign=email_promo.

Best practice: Use consistent naming conventions (e.g. 'source=whatsapp' and 'medium=link') to make reporting easier.

2. Shortened and tracked links

Use tools such as Bitly or Rebrandly to shorten URLs and add tracking. Add UTMs and then monitor clicks.

• Email integration: Track whether a WhatsApp click leads to an email event by correlating timestamps or user IDs in your CRM.
• Advanced: Use dynamic links that are personalised based on WhatsApp data and trigger email sequences when clicked.

3. Pixel tracking and events

Add tracking pixels to landing pages that are linked from WhatsApp. Tools such as Facebook Pixel and Google Tag Manager can capture events (e.g. form submissions) that lead to email conversions.

• Cross-channel tie-in: set up custom events for 'whatsapp_to_email_transition' to log when a visit from WhatsApp results in an email action.

4. API integrations and webhooks

To enable deeper tracking, use the WhatsApp Business API to send and receive messages and webhooks for click notifications. Integrate with email platforms (e.g. ActiveCampaign) to log transitions on a unified dashboard.

These methods ensure that you capture the entire sales funnel, from the WhatsApp click to the email conversion.

Tools and platforms for effective tracking.

Using the right tools makes cross-channel tracking easier.

• Google Analytics 4 (GA4): Free and powerful UTM tracking. Set up events for email conversions from WhatsApp sources. Visualise funnels in reports.
• Braze or Klaviyo: These are customer engagement platforms that integrate WhatsApp, email and SMS. Track transitions with built-in analytics and AI personalisation.
• ActiveCampaign: Unifies channels in one dashboard and automates sequences based on WhatsApp interactions that lead to emails.
• Bitly or Rebrandly: For link shortening and basic click tracking. Integrates with email tools.
• HubSpot or Salesforce: These are CRM systems that track multi-channel journeys, including WhatsApp-to-email handoffs.

A dashboard like this can display metrics such as the number of WhatsApp sessions leading to email opens, which can help to refine strategies.

Advanced users can combine it with AWS or custom APIs for real-time tracking across channels.

Step-by-step implementation

1. Define goals: Decide what to track, for example email signups from WhatsApp links.
2. Tag links: Use UTM builders to add parameters to WhatsApp URLs.
3. Set up Analytics: in GA4, create conversions for email events and integrate with your email platform.
4. Test links: Send test WhatsApp messages and verify the data in Analytics.
5. Monitor and optimise: Review reports weekly and adjust based on CTRs and conversions.

Although integration takes 1–2 hours initially, it saves time in the long term.

Best practices and challenges.

• Consistency: Standardise UTM naming conventions across campaigns.
• Privacy compliance: Obtain opt-ins for WhatsApp and email.
• Frequency capping: Avoid spamming to prevent being blocked.
• Challenges: WhatsApp's encryption limits tracking, but this can be overcome with redirects. Low engagement? Test rich media in messages.

Real-world examples

Brands such as Kredi use WhatsApp chatbots to qualify leads and then transition to email to recover detailed information, successfully recovering 80% of incomplete requests. Meanwhile, Carvuk sends WhatsApp quotes with links to email confirmations, thereby boosting bookings.

‍

Conclusion

Tracking transitions from WhatsApp to email provides deeper insights into customer behaviour, enabling personalised and effective marketing. You can measure and optimise these journeys by using UTMs, tools like GA4, and integrated platforms. Start small, conduct thorough testing, and watch your cross-channel ROI increase.
