Managing performance marketing across multiple client accounts is genuinely complex. You need to generate creatives at scale, launch campaigns efficiently, surface winning combinations quickly, and prove ROI to clients without burning through your team's hours. The right platform makes all of this manageable. The wrong one creates more overhead than it removes.
This list covers the best performance marketing platforms built for agency workflows in 2026. Each tool was selected based on multi-client management capabilities, automation depth, creative production features, reporting transparency, and overall value for teams running paid social, search, or programmatic campaigns.
Whether you run a boutique shop managing a handful of DTC brands or a mid-size agency handling dozens of accounts, there is a platform here that fits your workflow.
1. AdStellar
Best for: Agencies running Meta campaigns that need AI-powered creative generation and campaign management in one platform.
AdStellar is a full-stack AI ad platform that generates creatives, builds and launches Meta campaigns, and surfaces winning ads with performance scoring and leaderboard insights.
Where This Tool Shines
Most agencies juggle separate tools for creative production, campaign management, and performance analysis. AdStellar collapses all three into a single workflow. You can go from a product URL to a live Meta campaign with AI-generated image ads, video ads, and UGC-style avatar creatives without involving a designer or video editor.
The AI Campaign Builder is where it gets particularly useful for agencies. It analyzes your historical performance data, ranks every creative, headline, and audience by results, and builds complete campaigns with full transparency into its reasoning. That transparency matters when you need to explain strategy to clients, not just hand them a report.
Key Features
AI Ad Creative: Generate image ads, video ads, and UGC-style avatar content from a product URL, clone competitor ads directly from the Meta Ad Library, or let AI build creatives from scratch with chat-based refinement.
AI Campaign Builder: Analyzes historical performance data and builds complete Meta campaigns with transparent rationale for every decision, so you understand the strategy behind the output.
Bulk Ad Launch: Creates hundreds of ad variations across creatives, headlines, audiences, and copy combinations in minutes, reducing campaign setup from hours to clicks.
AI Insights: Leaderboards rank every creative element by ROAS, CPA, and CTR against your defined goals, so you can instantly identify what is working and why.
Winners Hub: Centralizes top-performing creatives, headlines, and audiences with real performance data attached, making it easy to reuse proven assets across campaigns and clients.
Best For
Agencies managing Meta and Instagram campaigns for DTC, e-commerce, or direct response clients. Particularly strong for teams that want to reduce their dependence on external creative resources while increasing the volume and speed of campaign testing.
Pricing
Hobby at $49/month, Pro at $129/month, and Ultra at $499/month. A 7-day free trial is available with no commitment required.
2. Google Marketing Platform
Best for: Agencies managing large cross-channel budgets across search, display, video, and programmatic inventory.
Google Marketing Platform is an enterprise suite connecting Display and Video 360, Search Ads 360, Campaign Manager 360, and Analytics 360 for unified cross-channel campaign management.
Where This Tool Shines
When your agency is running significant spend across Google's entire ecosystem, having a unified layer that connects programmatic buying, search management, and analytics is genuinely valuable. The integration between these products means audience data, conversion signals, and campaign performance all flow into a single view.
For agencies with dedicated ad operations teams, the depth of control available in Display and Video 360 for programmatic buying is difficult to match. It is not a lightweight tool, but for the right agency profile it is the most comprehensive option in Google's channel.
Key Features
Display and Video 360: Programmatic buying and creative management across display, video, and connected TV inventory.
Search Ads 360: Cross-engine search campaign management covering Google, Microsoft, and other search publishers from one interface.
Campaign Manager 360: Ad serving, tracking, and measurement across all digital channels with unified attribution.
Analytics 360: Enterprise-grade analytics integration connecting audience data directly to campaign execution.
Multi-client management: Agency-level controls with client-specific access and reporting configurations.
Best For
Larger agencies or in-house teams with dedicated media buying operations managing substantial budgets across Google's ecosystem. Requires technical expertise to get full value from the platform.
Pricing
Enterprise pricing negotiated based on spend volume. Contact Google directly for agency-specific rates.
3. HubSpot Marketing Hub
Best for: Agencies managing B2B or SaaS clients where connecting ad spend to pipeline and revenue is the primary reporting requirement.
HubSpot Marketing Hub is a CRM-native marketing platform that connects paid ad performance directly to pipeline and revenue data for B2B-focused agency clients.
Where This Tool Shines
The core strength here is attribution at the contact and deal level. When your client's success metric is pipeline generated rather than clicks or impressions, HubSpot connects ad spend on Google, Facebook, and LinkedIn directly to the CRM contacts and deals those ads influenced. That is a reporting story most B2B clients respond to immediately.
For agencies with clients already running HubSpot CRM, adding Marketing Hub creates a full-funnel view that pure ad platforms cannot replicate. It is less about raw campaign optimization and more about connecting marketing activity to business outcomes.
Key Features
CRM-connected ad management: Ad campaigns for Google, Facebook, and LinkedIn with performance data tied directly to contact and deal records.
Pipeline attribution: Links ad spend to specific deals and revenue, giving clients a clear view of marketing's contribution to sales.
Agency partner program: Multi-account management with agency-level controls and partner pricing available.
Automated client dashboards: Reporting templates that surface the metrics B2B clients care about most.
Full-funnel visibility: Connects top-of-funnel ad activity through to closed revenue in a single platform.
Best For
Agencies whose clients are already in the HubSpot ecosystem or those focused on B2B and SaaS clients where pipeline attribution and revenue reporting are central to the engagement.
Pricing
Starter from $20/month. Professional and Enterprise tiers available. Agency partner pricing is negotiated separately through HubSpot's partner program.
4. Skai
Best for: Agencies managing e-commerce clients across traditional social and search channels alongside retail media networks like Amazon and Walmart.
Skai is an omnichannel performance marketing platform covering search, social, and retail media networks with AI-powered budget optimization.
Where This Tool Shines
Retail media is no longer optional for agencies with e-commerce clients. Skai is one of the few platforms that genuinely unifies campaign management across Google, Meta, Amazon, Walmart, Instacart, and other retail media networks in a single interface. That breadth is the primary reason agencies choose it.
The AI-powered budget allocation and forecasting tools are particularly useful when managing spend across channels with very different cost structures and return profiles. Rather than manually rebalancing budgets, Skai can automate that optimization based on performance signals across the entire portfolio.
Key Features
Retail media management: Unified campaign management across Amazon, Walmart, Instacart, and other retail media networks alongside traditional channels.
Cross-channel budget optimization: AI-powered allocation and forecasting that moves budget toward the best-performing channels automatically.
Unified campaign management: Google, Meta, and retail media all managed from a single interface with consistent reporting.
Multi-client dashboards: Agency-level reporting tools with client-specific views and performance summaries.
Audience management: Cross-channel audience insights and segmentation to improve targeting consistency.
Best For
Agencies with e-commerce and retail clients that need to manage Amazon and other retail media networks alongside social and search. Strong fit for agencies where retail media represents a growing share of client spend.
Pricing
Enterprise pricing, not publicly listed. Contact Skai directly for agency-specific rates.
5. Madgicx
Best for: Agencies running Meta and Google performance campaigns for e-commerce brands that want autonomous budget management with AI audience recommendations.
Madgicx is a Meta and Google ad optimization platform with autonomous budget management rules and AI-powered audience recommendations.
Where This Tool Shines
The autonomous ad buying rules are the standout feature for agencies. You define the conditions and Madgicx executes budget adjustments, bid changes, and campaign actions automatically based on real-time performance data. For agencies managing multiple Meta accounts, this removes a significant amount of daily manual work.
Creative analytics in Madgicx gives you ad-level performance breakdowns that help identify which creative elements are driving results. Combined with the one-click reporting for client-facing summaries, it covers both the optimization and communication sides of agency work reasonably well.
Key Features
Autonomous ad buying rules: Automated budget management and bid optimization based on performance conditions you define, running continuously without manual intervention.
AI audience recommendations: Targeting suggestions based on performance data to improve reach and reduce wasted spend.
Creative analytics: Ad-level performance breakdown to identify which creative elements are contributing to results.
Multi-account management: Agency workflow tools for managing multiple client accounts from a single interface.
One-click reporting: Client-facing performance summaries generated quickly without manual data assembly.
Best For
Agencies running performance campaigns for e-commerce brands on Meta and Google that want rule-based automation to reduce manual optimization work across multiple accounts.
Pricing
Publicly listed pricing with agency plans available. Visit madgicx.com for current tiers and agency-specific options.
6. Smartly.io
Best for: Larger agencies or enterprise in-house teams with high creative volume requirements across multiple social channels.
Smartly.io is an enterprise creative automation and social campaign management platform supporting Meta, TikTok, Pinterest, and Snapchat at high volume.
Where This Tool Shines
Creative automation at true enterprise scale is what Smartly does best. The template-based production system lets agencies build dynamic creative frameworks that automatically generate personalized ad variations from product feeds, audience segments, or campaign parameters. For agencies running e-commerce clients with large product catalogs, this is a significant time saver.
The multi-channel social coverage is also broader than most competitors. Managing Meta, TikTok, Pinterest, and Snapchat from a single platform with consistent reporting and automated A/B testing reduces the operational complexity of running cross-platform social campaigns for multiple clients simultaneously.
Key Features
Dynamic creative automation: Template-based creative production that generates personalized ad variations at scale from product feeds and audience data.
Multi-channel social management: Unified campaign management across Meta, TikTok, Pinterest, and Snapchat from a single interface.
Automated A/B testing: Continuous creative testing and optimization without manual setup for each experiment.
Feed-based personalization: Creative variations driven by product catalog data for e-commerce clients with large inventories.
Agency multi-account management: Client-level controls and reporting configurations for agency workflows.
Best For
Larger agencies and enterprise in-house teams with high creative volume requirements across multiple social platforms. The investment required makes it best suited for teams with substantial monthly ad spend.
Pricing
Enterprise pricing, not publicly listed. Contact Smartly.io directly for agency-specific rates and minimum spend requirements.
7. Triple Whale
Best for: Agencies managing Shopify-based DTC brands that need accurate attribution and creative-level revenue data to guide optimization decisions.
Triple Whale is an attribution and analytics platform built for Shopify-based DTC brands, connecting ad spend to revenue and profit with creative-level performance data.
Where This Tool Shines
The attribution challenge for DTC brands running Meta campaigns has intensified with iOS signal loss and increasing privacy restrictions. Triple Whale addresses this with pixel-based attribution and modeled data that gives agencies a more accurate picture of which ads are actually driving revenue, rather than relying solely on Meta's reported numbers.
The profit dashboard is genuinely useful for client conversations. Rather than reporting on ROAS in isolation, Triple Whale connects ad spend to blended margin data so agencies can show clients the full financial picture of their campaigns. That context transforms reporting from a vanity exercise into a business conversation.
Key Features
Pixel-based attribution: First-party attribution with modeled data to account for iOS signal loss and browser tracking restrictions.
Creative analytics: Ad-level performance dashboard tracking creative results tied to actual revenue rather than platform-reported metrics.
Profit dashboard: Connects ad spend to blended margin data, giving agencies and clients a complete financial view of campaign performance.
Cohort analysis and LTV reporting: Customer lifetime value and cohort data to support longer-term campaign strategy decisions.
Agency multi-client management: Agency plans with multi-account access and client-level reporting views.
Best For
Agencies focused on Shopify-based DTC clients where accurate attribution and profit-level reporting are central to demonstrating campaign value. Best used alongside a campaign management platform rather than as a standalone ad tool.
Pricing
Publicly listed pricing with agency plans available. Visit triplewhale.com for current tiers and multi-client pricing options.
8. Marin Software
Best for: Search-focused agencies managing large budgets across Google, Microsoft, Amazon, and Meta that need cross-publisher bid management and forecasting.
Marin Software is a cross-publisher bid management platform covering Google, Meta, Amazon, and Microsoft with forecasting tools for large-scale agency campaign management.
Where This Tool Shines
Marin's core strength is bid management at scale across multiple publishers. For agencies running significant search budgets across Google and Microsoft simultaneously, having unified bid management with cross-publisher performance analysis in a single interface reduces the coordination overhead considerably.
The budget pacing and forecasting tools are particularly valuable for agencies managing clients with strict monthly spend targets. Marin tracks pacing in real time and provides forecasting that helps agencies stay on budget without constant manual monitoring. That operational reliability matters when you are managing dozens of client accounts.
Key Features
Unified bid management: Cross-publisher bid optimization across Google, Meta, Amazon, and Microsoft Ads from a single platform.
Budget pacing and forecasting: Real-time pacing tracking and spend forecasting for agencies managing clients with defined monthly budgets.
Keyword and audience management at scale: Tools for managing large keyword lists and audience segments across multiple accounts efficiently.
Cross-publisher performance analysis: Optimization recommendations that account for performance data across all connected publishers.
Best For
Search-heavy agencies managing substantial budgets across multiple publishers where bid management precision and forecasting accuracy are primary operational requirements.
Pricing
Enterprise pricing negotiated based on spend volume. Contact Marin Software directly for agency-specific rates.
9. Reportei
Best for: Agencies of any size that need to automate white-label client reporting across Google Ads, Meta Ads, Google Analytics, and social channels.
Reportei is an automated multi-channel reporting platform that generates white-label client reports from Google Ads, Meta Ads, Google Analytics, and other sources.
Where This Tool Shines
Client reporting is one of the most consistent time drains in agency operations. Reportei addresses this directly by pulling data automatically from all major ad and analytics platforms and assembling it into branded, client-ready reports. What previously took hours of manual data pulling and formatting can be reduced to minutes with scheduled delivery.
The white-label capabilities make it genuinely useful for agencies that want reports to feel like a native part of their service rather than an export from a third-party tool. Customizable templates and layouts mean you can match reports to client preferences without rebuilding from scratch each time.
Key Features
Automated report generation: Pulls data from Google Ads, Meta Ads, Google Analytics, and social channels automatically without manual data assembly.
White-label templates: Client-facing report templates with agency branding for professional, on-brand delivery.
Customizable dashboards and layouts: Flexible report structures that can be tailored to individual client preferences and KPIs.
Scheduled report delivery: Automated report sending to clients on a defined schedule, removing the manual delivery step entirely.
Multi-account management: Agency tools for managing reports across multiple client accounts from a single interface.
Best For
Agencies of any size where client reporting is a significant time investment. Particularly useful as a complement to campaign management platforms rather than a standalone performance tool.
Pricing
Publicly listed pricing accessible for agencies of various sizes. Visit reportei.com for current plans and multi-client options.
Which Platform Is Right for Your Agency?
The honest answer is that most agencies will benefit from combining two or three of these platforms rather than relying on a single tool. The platforms on this list solve different problems, and the best stack depends on where your biggest operational constraints actually live.
If your agency runs Meta and Instagram campaigns and needs AI to handle creative production, campaign building, and performance scoring in one place, AdStellar is the strongest starting point. It covers the full workflow from creative generation through campaign launch and winner identification, which is the combination that reduces the most manual work for Meta-focused teams.
For agencies managing large cross-channel budgets across search, display, and programmatic, Google Marketing Platform or Marin Software offer the depth and control that enterprise-scale campaign management requires. DTC-focused agencies should look closely at Triple Whale for attribution clarity alongside AdStellar for creative and campaign automation. That pairing addresses both the campaign execution side and the accurate revenue attribution side of the DTC agency workflow.
Agencies with e-commerce and retail media clients will find Skai's cross-channel capabilities particularly useful as retail media spend continues to grow as a share of total digital budgets. If reporting efficiency is the primary bottleneck, Reportei solves that problem quickly and at an accessible price point for agencies of any size.
The most common and effective pairing is a creative and campaign platform like AdStellar alongside a reporting or attribution layer like Triple Whale or Cometly. Start with the platform that addresses your biggest current constraint, whether that is creative production speed, campaign management overhead, or client reporting, and build from there.
AdStellar offers a 7-day free trial, which makes it a low-risk starting point for agencies running Meta campaigns. Start Free Trial With AdStellar and see how quickly AI-powered creative generation and campaign building can change the pace of your agency's output.
