What is a customer journey builder and how does it work?
The customer journey builder is an essential tool in any digital marketing strategy.
It lets you design and automate the interactions a subscriber has with your brand from the first contact until they become a loyal customer.
With an email marketing solution like Mailrelay, you can build these journeys easily thanks to automation, segmentation, personalization and real-time metrics analysis.
This not only improves the user experience, it also increases conversion and retention rates.
What is a customer journey builder?
A customer journey builder, also known simply as a journey builder, is a tool that lets you design the path each user follows throughout their relationship with a brand.
Instead of sending identical mass emails, this technology enables personalized flows that respond to specific actions:
- Newsletter subscription
- Clicking a link
- Cart abandonment
- Etc.
For example, below you can see a journey with a welcome email:

And below you would have a cart recovery journey, or abandoned cart, with a final condition to check whether the recovery email has been opened or not. Which would allow you to continue with an email flow:

These are just two simple examples, but there would be many options for automated journeys.
The importance of the customer journey builder in email marketing
In the field of email marketing, the customer journey builder becomes a strategic ally because:
- Increases personalization: each message adapts to the subscriber’s behavior.
- Automates tasks: it saves time and reduces errors by triggering emails at key moments.
- Increases conversions: timely messages generate greater engagement and sales.
- Builds customer loyalty: it maintains the relationship after the purchase, preventing disengagement.
- Lets you measure results: it makes it easy to track metrics such as opens, clicks and ROI.

How a customer journey builder works
Above you have seen several examples of flows; if you take a look at them you will see that it is simply a matter of adding steps (the add button) and configuring the actions you want, such as waits, email sends, conditions, etc.
How this tool works is based on several key elements:
- Segmentation: grouping users by interests or actions.
- Triggers: events that trigger emails (e.g. a subscription or a click).
- Personalized messages: emails adapted to each stage of the journey.
- Conditions and branching: different paths depending on the user’s response.
- Automation: automatic execution of the defined flows.
This way the flows are highly personalized and can be genuinely useful for maintaining unique communication with your contacts.

The most common customer journeys
A customer journey builder is used in different scenarios, but the most common ones would be:
- Welcome series: after subscribing, the user receives a welcome email, followed by useful information and a first offer.
- Abandoned cart: if the purchase is not completed, a reminder email is sent, followed by usage recommendations or related products.
- Personalized offers: if a user shows interest in a specific topic, for example by clicking a link, they receive content aligned with their preferences.
- Drip campaigns: planned to send emails over set periods

For journeys to work, it is worth applying these recommendations:
- Segment your contact list correctly.
