Head-to-head comparison (practical takeaways)
| Area | AdButler | Epom | Takeaway |
|---|---|---|---|
| Delivery model | Complete ad server + robust APIs | Ad server + white-label DSP | Choose AdButler for direct-sold focus; Epom if you need DSP bundled. |
| Newsletter/email | Per-open logic; update after send (EUID + persistence) | Site emphasizes rich-media/web/app; newsletter flow not marketed | AdButler leads in newsletters. |
| Self-serve | Built-in, white-label portal (payments, approvals, reports; GAM bridge) | Self-serve programmatic (DSP) rather than a publisher's advertiser portal | Different "self-serve" scopes. |

Frequently Asked Questions
How long does migration typically take?
Most customers complete migration in 2-4 weeks. Inventory mapping takes 1-2 days, newsletter migration about a week with testing, and advanced features can be activated incrementally. No disruptive big-bang cutover required.
What's the typical ROI timeline?
Most publishers see measurable improvements within 30-60 days: increased email ad revenue from per-open delivery, reduced operational costs from automation, and new revenue from self-serve portal adoption. Retail customers typically launch sponsored products within 4-6 weeks.
Which platform provides the more complete ad-serving stack?
Both AdButler and Epom provide hosted ad serving, targeting, campaign management, reporting, APIs, white-labeling, and support for multiple digital formats. AdButler delivers these core capabilities alongside publisher-owned self-service, advanced newsletter monetization, first-party audiences, AI-powered contextual targeting, sponsored products, retail media, programmatic demand, and enterprise infrastructure.
How does AdButler ad serving compare with Epom?
Both platforms can manage advertisers, campaigns, inventory, creative, targeting, pacing, delivery, tracking, and reporting. Epom emphasizes rich-media formats, API customization, white-labeling, and its wider programmatic product suite. AdButler provides enterprise ad serving across more owned channels and connects it with self-service, audiences, commerce media, and custom engineering.
Does AdButler support the same major formats as Epom?
Yes. Both platforms support display, native, mobile, video, rich media, and DOOH advertising. AdButler also provides dedicated email ad serving, CTV, sponsored products, shoppable video, native mobile SDKs, and customizable JSON-delivered formats for commerce and other native experiences.
Which platform provides stronger rich-media capabilities?
Epom publicly emphasizes its library of more than 30 ready-made rich-media templates, which can be useful for teams that want to launch interactive formats without developing them independently. AdButler supports rich media, native, video, shoppable formats, APIs, and custom creative development. The right choice depends on whether ready-made templates or broader customization and channel coverage matter more.
Do AdButler and Epom both support video advertising?
Yes. Both platforms support video advertising and VAST-based delivery. AdButler extends video into mobile apps, OTT and CTV environments, and shoppable video experiences that can combine video creative with product information and native companion content.
Do both platforms support mobile and DOOH advertising?
Yes. AdButler and Epom both support mobile and digital out-of-home advertising. AdButler also provides native iOS and Android SDKs and can connect mobile and DOOH delivery with email, web, video, retail media, audiences, and other owned channels.
What does AdButler provide beyond multi-format ad serving?
AdButler extends its core ad server with white-label advertiser self-service, email ads with per-open decisioning, first-party audience management, AI-powered contextual segmentation, sponsored products and retail media, direct and programmatic demand, ProductDB and the JSON Ad API, mobile SDKs, enterprise security and infrastructure, and direct engineering and integration support. These capabilities allow businesses to operate a broader media network rather than assemble separate products around a core ad server.
Is AdButler an Epom alternative?
Yes. AdButler is an alternative for publishers, retailers, marketplaces, ad networks, platforms, and other media owners that require hosted ad serving, targeting, reporting, APIs, multiple formats, white-labeling, and programmatic integrations. It is particularly relevant when the business also needs self-service, newsletters, retail media, first-party targeting, or enterprise controls.
How does AdButler self-service differ from Epom's self-service DSP?
AdButler's Self-Serve Portal allows advertisers to purchase a publisher or media owner's directly controlled inventory through a branded marketplace. Epom's self-service DSP allows advertisers to buy programmatic inventory. AdButler automates publisher-owned media sales, while Epom's DSP automates programmatic media buying.
Can AdButler's Self-Serve Portal work with Google Ad Manager?
Yes. The AdButler Self-Serve Portal can connect with Google Ad Manager, allowing advertisers to purchase campaigns through a branded experience while GAM remains the delivery platform. The same portal can operate directly with AdButler's enterprise ad server.
Do AdButler and Epom both support white-labeling?
Yes, but the products differ. AdButler supports white-label advertiser portals and customer-facing platform experiences. Epom offers white-labeling for its ad server and sells a separate white-label DSP. Buyers should distinguish between branding an ad-management interface, operating a publisher-owned advertiser marketplace, and providing clients with a programmatic buying platform.
Can AdButler update newsletter advertisements after send?
Yes. AdButler's Email User ID and ad-persistence capabilities support per-open decisioning, unique recipient delivery, and creative changes after a newsletter has been delivered. Epom's public ad-server materials do not position dedicated newsletter delivery or post-send email updates as central capabilities.
Does AdButler support sponsored products and retail media?
Yes. ProductDB and the JSON Ad API support sponsored listings, promoted products, native catalog placements, and other commerce-media experiences. Retailers can combine these capabilities with self-service buying, first-party targeting, display, video, programmatic demand, reporting, and omnichannel delivery.
Which platform provides stronger audience targeting?
AdButler combines UserDB first-party audiences with AI-powered contextual categories, keywords, tags, geography, device, product data, and custom targeting. Epom supports targeting and can use advertiser or publisher data through its API. Buyers should compare how audiences are built, governed, activated, analyzed, and connected with other systems.
Do AdButler and Epom both provide APIs?
Yes. Epom provides a REST API using JSON and XML for campaign management, reporting, targeting, creative workflows, and integrations. AdButler provides ad-serving, management, reporting, and JSON APIs alongside mobile SDKs and direct engineering support.
Which platform is better for building custom ad tech?
Both platforms support customization. Epom positions its hosted ad server and API as an alternative to building infrastructure from scratch. AdButler combines APIs with direct engineering support for proprietary formats, targeting rules, workflows, reporting, integrations, and embedded advertising products.
Which platform provides stronger reporting and analytics?
Both platforms provide campaign reporting and API access. Epom offers standard reporting with optional Advanced Analytics for additional filters and extended data retention. AdButler provides dashboards, scheduled reporting, APIs, exports, log-level data options, and custom reporting development for enterprise workflows.
Do both platforms support programmatic advertising?
Yes, but their product structures differ. Epom offers a separate DSP, a white-label DSP, and an optional SSP module. AdButler integrates programmatic demand with direct campaigns, self-service advertisers, sponsorships, and other media-owner inventory within the broader AdButler stack.
Can AdButler prioritize direct campaigns over programmatic demand?
Yes. AdButler allows media owners to establish campaign priority, inventory allocation, fallback behavior, pricing rules, and demand access. This supports a hybrid model in which premium direct and self-service relationships are prioritized while programmatic demand complements fill.
Which platform is better for publishers and ad networks?
Epom can be a strong fit for publishers and ad networks that prioritize rich-media templates, API automation, white-label ad serving, or access to Epom's separate DSP and SSP products. AdButler is stronger when the organization wants multi-format ad serving plus self-service sales, newsletters, audiences, retail media, programmatic demand, and enterprise infrastructure in one stack.
Which platform is better for retailers and marketplaces?
AdButler provides more purpose-built retail media infrastructure through ProductDB, the JSON Ad API, sponsored products, native commerce placements, advertiser self-service, first-party audiences, and omnichannel delivery. Epom supports multiple formats, APIs, targeting, and custom creative workflows but does not publicly emphasize a comparable sponsored-product database.
How do AdButler and Epom compare on pricing?
AdButler publicly lists plans starting from $179 per month. Epom currently lists Light from $250, Growth from $1,000, Pro from $2,500, and custom Enterprise pricing. White-labeling, premium support, Advanced Analytics, and the SSP module are separately priced options.
Which platform provides stronger enterprise infrastructure?
AdButler provides SOC 2 Type II compliance, SSO/SAML, 99.99% uptime, global infrastructure, data residency options, and enterprise controls. Epom references GDPR and CCPA tools, consent synchronization, dedicated support, and global infrastructure. Buyers should verify specific audit reports, identity controls, uptime commitments, hosting, and retention requirements during procurement.
Can businesses migrate gradually from Epom to AdButler?
Yes. Organizations can begin with one website, app, channel, inventory group, or set of campaigns and validate delivery, targeting, reporting, and integrations before expanding. AdButler provides onboarding and migration assistance, with architecture planning and engineering support available for complex deployments.
Should we choose AdButler or Epom?
Choose Epom if your primary priorities are hosted multi-format ad serving, ready-made rich-media templates, API customization, white-label DSP capabilities, and access to Epom's wider programmatic suite. Choose AdButler if you want those core ad-serving capabilities plus publisher-owned self-service, advanced newsletters, first-party and contextual audiences, retail media, sponsored products, programmatic demand, omnichannel delivery, and enterprise infrastructure.
