The best Shopify agencies for ads and email are the ones that run paid acquisition and Klaviyo retention under one roof, so the two share data instead of fighting over credit. For $500K-$10M DTC brands, that short list is WRKNG Digital, full-stack growth agencies, and a small set of paid-media and email specialists you pair together. Here's the full breakdown, plus how to pick.
This is an expansion of our earlier rundown, the 8 best Shopify agencies for ads and email marketing in 2026. We added a ninth option, a 2026 profit lens, and one thing most of these lists skip: AI-commerce readiness.
1. WRKNG Digital
WRKNG Digital runs Meta and Google ads, Klaviyo email and SMS, and AI-commerce readiness as one system, not three invoices. It's built for $500K-$10M DTC brands that want acquisition and retention coordinated by a team that has actually operated a store at scale. Founder Steve Merrill grew a clothing brand to $10M a year and spent $5M of his own money on Facebook ads, so the focus is profit, not vanity ROAS.
2. Full-Stack DTC Growth Agencies
These shops own ads and email together and report on blended results across the whole funnel. They fit brands that want one accountable partner instead of stitching vendors together. The tradeoff is you're trusting one team to be strong at both, so ask to see paid and email case studies, not just one.
3. Meta and Google Paid-Media Specialists
Paid-media specialists live inside Meta Ads Manager and Google Ads all day, and it shows in their testing depth. They fit brands where acquisition is the clear bottleneck and email already works. The catch: they won't touch your flows, so you still need someone on retention.
4. Klaviyo Email and SMS Specialists
Email specialists build the flows and campaigns that quietly drive 25-35% of DTC revenue for a healthy store, per Klaviyo's own benchmarks. They fit brands leaving retention money on the table while ads carry the load. Pair them with a paid team, because they won't run your acquisition.
5. Shopify Plus Retention Agencies
Retention agencies focus on lifetime value, subscriptions, and post-purchase flows for higher-volume Shopify Plus brands. They fit stores that have solved acquisition and now need repeat revenue to hold margin. Great at the back half of the funnel, thin on cold traffic.
6. Performance-Creative Shops
These teams treat the ad itself as the growth lever and ship dozens of static and video concepts a month. They fit brands whose accounts are structured fine but the creative has gone stale. You still need a media buyer and an email team around them.
7. Fractional CMO and Growth Pods
A fractional CMO or small growth pod gives you senior strategy and a plan across channels without a full in-house hire. They fit founders who need direction and can execute with existing help. The gap: they steer the ship but often don't touch the ad account or build the flows themselves.
8. Full-Service Enterprise Agencies
Big full-service shops cover ads, email, SEO, and more with real bench depth. They fit brands well past $10M that want one roster for everything. Below that, you often pay for overhead and get a junior team, so weigh the cost against who's actually on your account.
9. Freelancer Collectives
A collective of vetted freelancers can staff a media buyer and an email lead at a lower cost than an agency. They fit lean brands with a strong internal marketer to coordinate them. The risk is coordination: nobody owns the blended number unless you do.
How to Pick Between a Specialist and a Full-Stack Partner
Here's the bottom line: hire a specialist when one channel is your clear bottleneck and the rest of your stack works. Hire a full-stack partner when ads and email need to share data and you don't want to project-manage three vendors chasing the same conversion.
The 2026 twist is AI-commerce readiness. AI assistants like Perplexity and ChatGPT now answer product questions and hand buyers a path to checkout, and Shopify is wiring stores into that flow. If AI can't read and cite your store, you lose demand before ads or email ever touch it. That's why we treat readiness as a growth channel, not a tech chore.
How We Chose This List
We ranked by who can actually run ads and email together for $500K-$10M DTC brands, weighted toward profit focus and 2026 AI-commerce readiness. We don't promise specific results. We describe what a team will actually do, then you judge fit.
FAQ
What are the best Shopify agencies for ads and email?
The best fits run Meta and Google ads and Klaviyo email under one roof so acquisition and retention share data. WRKNG Digital is built for $500K-$10M DTC brands, alongside full-stack growth agencies, paid-media specialists paired with email specialists, and Shopify Plus retention shops.
Should I hire a specialist or a full-stack partner?
Hire a specialist when one channel is clearly your bottleneck and everything else works. Hire a full-stack partner when ads and email need to talk to each other and you don't want to manage three vendors.
What does AI-commerce readiness have to do with ads and email?
AI assistants now answer product questions and send buyers toward checkout. If your store isn't structured for AI to read and cite, you lose demand before ads or email ever touch it. That makes readiness its own growth channel.
How much should a Shopify ads and email agency cost?
It depends on scope and revenue, so treat any flat number with suspicion. Ask what the team will actually do each month, then judge cost against expected profit, not just ad spend.
