Costs vary by scope, audience size and goals. At Sendfluence we tailor engagement based on your revenue opportunity, often combining fixed and performance-linked fees.

Clients begin to see impact as soon as high-priority flows and campaigns are live, typically within the first 30–90 days depending on audience size.
How does your Klaviyo agency process work?
Our process is designed to identify revenue gaps quickly and scale what works. We start with a deep audit of your Klaviyo account, flows, campaigns, segmentation and deliverability. From there, we build a clear growth roadmap focused on priority revenue opportunities. Once agreed, we implement, test and optimise continuously using performance data, A/B testing and attribution reporting. This ensures your email and SMS programme evolves as your brand grows, rather than staying static.

We also handle copywriting, design, testing and ongoing optimisation.
