JavaScript & Custom Development
Custom JavaScript for landing pages, forms, tracking scripts, and marketing automation platforms - plus webhook configuration, application hosting, and script review for existing implementations.
Marketing platforms have limits.
When native functionality stops short of a defined requirement - a complex tracking implementation, a form behavior that requires custom logic, a webhook that needs to handle edge cases the platform doesn't account for - custom development is the only path forward. Tactical Marketing writes, reviews, and deploys custom JavaScript and webhook configurations as operational components, not one-off scripts.
Our Approach
We write JavaScript that works within the constraints of the platforms it runs on - marketing automation landing pages, form handlers, tracking layers - and we review existing scripts for logic errors, performance issues, and alignment with marketing objectives before inheriting them.
Webhook work covers both inbound and outbound configurations, with validation testing that confirms real-time data sync behaves correctly under live conditions.

Frequently Asked Questions
How do you identify what's actually broken versus what just looks broken?
We audit systematically - program logic, trigger conditions, data sync behavior, and the integration layer - rather than reacting to surface symptoms. Most environments have failures that aren't visible in the platform UI at all.
How long does an audit or repair engagement typically take?
A thorough audit runs 2–3 weeks. A structured repair or rebuild depends on the depth of the technical debt - most range from 4–10 weeks. We scope each engagement after the initial audit so you know what you're committing to.
Do you provide ongoing management after the repair work is done?
Often, yes. Many clients transition into a managed services arrangement where Tactical Marketing handles ongoing administration, governance, and platform maintenance. Others prefer to hand back to an internal team - in which case we document everything and run a formal knowledge transfer.
