If you're comparing quotes for Klaviyo help, the numbers can feel all over the place. Here's how agencies price this work in 2026, according to published ranges, and how to compare quotes fairly.
Monthly retainers
Retainers are the most common model. Published 2026 ranges cluster around $2,500–$10,000 a month, and most mid-market brands land around $4,000–$8,000 for full email and SMS management: strategy, flows, campaigns, segmentation, testing and reporting (Maestra; RetentionControl). Some specialists quote $3,000–$12,000 a month depending on volume (EmailOptimize).
One-time projects
Audits, setups, migrations and flow rebuilds are usually priced per project, commonly $3,000–$15,000 depending on scope (EmailOptimize).
Performance pricing
Some agencies charge a share of email-attributed revenue, often 5–25%, sometimes on top of a smaller base fee (Maestra). Be careful here. Klaviyo's attribution window is a setting, and attributed revenue isn't the same as incremental revenue, so agree on the definition before you sign.
What's actually included
When you compare quotes, line up: - the number of campaigns per month (email and SMS); - which flows get built or rebuilt, and how often they're optimized; - who writes copy and who designs; - testing cadence; - reporting frequency and what it measures; - meetings (weekly calls cost the agency time, and you pay for it).
The Klaviyo bill is separate
Your Klaviyo subscription is billed by Klaviyo based on profile count and SMS usage. Agency fees cover the work, not the platform.
