There are many reasons why someone might choose to use two different marketing tools. One common reason being - able to reach a wider audience. For example, if one tool is better suited for reaching customers in a certain geographic region, while another is better for reaching customers of a certain age group, using both can help businesses reach their target market more effectively.

Performance marketers
You're running campaigns across multiple channels but your tracking data only updates when someone manually exports subscriber lists, so the segment counts you're optimising against are always a few hours behind — with this integration, every new subscriber lands in Customer.io instantly and your analytics stay current.
Customer success leads
You need to act fast on new customer signups and purchases, but delays in syncing email platform data mean you find out about new buyers too late in their onboarding window — automating both apps means every purchase and form submission updates your customer profiles immediately so your team can engage without delay.
🤝
Client account managers
You answer to stakeholders who want to see real-time subscriber growth and campaign engagement numbers, but manual reporting leads to constant delays and discrepancies — connecting these apps means your CRM and email data stay perfectly aligned, giving you accurate metrics for every client review.
🔄
E-commerce store owners
The volume of new subscriber signups and store orders is too high for anyone to keep up with by hand, leading to missed tags and unsegmented customer bases — this integration means every transaction and form submission syncs automatically across your store and messaging tools without manual data entry.
🎯
Lifecycle marketing specialists
You own the customer journey after signup and depend on upstream forms to hand over clean contact details, but manual handoffs create gaps in your automated email sequences — automating both apps means subscriber data flows seamlessly into Customer.io the moment forms are completed so your lifecycle campaigns never miss a beat.
🗂️
Data operations teams
You need a reliable customer history across all platforms but keep finding mismatched records between your email lists and behavioural tracking tools — with this integration, every subscriber event and profile update is recorded accurately across systems, ensuring clean data for your entire tech stack.
