Email and Klaviyo marketing for startups.

Flows, campaigns, design and list growth from one full-service email team. $2,000 a month, month-to-month.

The short answer

Wadabu is a full-service email marketing agency for consumer-brand startups. For $2,000 a month, it sets up or audits Klaviyo, builds the core flows, writes and designs weekly campaigns, grows the list with sign-up forms, segments by purchase history, and reports monthly on LTV, repeat rate and email revenue.

What does a full-service email marketing agency do?

It runs the whole channel: the platform setup, the automated flows, the weekly campaigns, the writing, the design, list growth and the reporting. You approve; the agency ships.

That matters because email is the channel startups most often half-build. A welcome email goes up at launch, nobody touches it again, and customers who would have bought twice never hear from the brand. A full-service team keeps the flows current and the campaigns going out every week.

Which email flows should a new brand set up first?

Flows are automated emails triggered by what a customer does. Build them in this order, starting with the ones closest to a purchase.

Flow Triggered by Its job
Welcome A new sign-up Turn a subscriber into a first order
Abandoned checkout Starting checkout without buying Recover orders that almost happened
Browse abandonment Viewing a product without adding it to cart Bring interested visitors back
Post-purchase A first order Set up the second order: how-to, reviews, cross-sell
Win-back No order for a set period Bring lapsed customers back before they're gone

Welcome and abandoned checkout come first. Post-purchase and win-back matter more as the customer base grows.

Why Klaviyo?

Klaviyo is the default for most consumer brands because it pulls in order, product and browsing data, so emails can be triggered and segmented by what each customer actually did. Wadabu builds in Klaviyo. Klaviyo's subscription is billed by Klaviyo, separate from Wadabu's fee.

How much is email worth to a startup?

Email earns its keep through second orders. Say a brand gets 1,000 new customers a month and 20% buy again. Lift that repeat rate to 25% and that's 50 more second orders a month. At a $60 average order, that's $3,000 a month in extra revenue, more than the $2,000 fee, before counting campaigns.

Higher LTV (lifetime value) also means the brand can afford to pay more to win each new customer, which makes paid ads easier to scale.

What does email marketing cost for a startup?

Wadabu charges $2,000 a month for email and retention, month-to-month. It's also part of the $5,000 bundle with ads, SEO and site work. For the wider market, see what a growth marketing agency costs in 2026.

Where does email fit with ads and SEO?

Ads and search bring the first order. Email and SMS bring the second and third. That's why bundle clients are measured on MER (marketing efficiency ratio) across every channel: the email program is judged on what it adds to total revenue, not just on opens and clicks.

Which Klaviyo flows should a new brand build first?
