Castle specialises in WhatsApp marketing designed to meet customers where they already communicate. By integrating WhatsApp one of the worlds most used messaging platforms into clients digital strategies, the agency sends targeted, bulk or personalised messages, notifications and updates directly to users phones. Their approach helps brands cut through inbox clutter and engage audiences with immediacy, leveraging high open- and click-through rates to increase sales, re-engage leads, and streamline communication.

Beyond broadcast messaging, Castle builds full messaging automation flows: segmenting audiences, integrating customer data, and triggering messages based on behaviours such as abandoned carts, lead forms, or shipping updates. This service blends marketing, CRM integration and customer journey automation to nurture leads, recapture lost customers and enhance overall conversion while reducing marketing costs and manual workload.

Castle International Reviews


Reviews from Google Maps are available on this profile.
We’ve been working with Connor and the team at Castle Marketing for several months now, and the results have been outstanding. They’ve completely turned around our online performance — Google Ads are running more efficiently than ever, Meta campaigns are consistently profitable, and our Shopify sales have seen real, measurable growth month after month.What really stands out is the communication and attention to detail. Connor is proactive, genuinely invested in our success, and always brings clear insight backed by data. Every week we get transparent reports, constructive ideas, and steady progress.A great team to work with — knowledgeable, reliable, results-driven but also very Friendly.We had worked with various other market companies over the last few years and most are just happy to take a monthly retainer and drop you company into the works profile. Castle work differently, work towards targets and genuinely want to grow and grow your company.I Highly recommend Castle to any business looking to grow their online sales properly. "

We have recently started using castle to market our heating and plumbing company. So far everything is perfect. Leads are coming in and the communication from the team is outstanding. "
Craig Unsworth's Review Sourced from Google
Excellent social media workshop with Shannon and Finbarr. The team were super professional and friendly and we got a lot out of the session. Will absolutely use their tips and planning methods going forward and would love to do some more training in the near future. "
