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. |
| Contextual audiences | Contextual Segments + Tags (AI + UI analytics) | Targeting + 30+ templates; contextual-segments UI not highlighted | Packaged context vs manual keys/templates. |
| Retail-media | ProductDB + JSON Ad API (catalog zones, ad-source targets) | Ad server + templates; no ProductDB module advertised | Faster RMN MVP with AdButler. |
| Shoppable video | VAST + product companion side-card | VAST supported; shoppable side-card not advertised | Built-in pattern vs custom. |
| APIs | JSON ad serving, Reporting, Management, SDKs | REST/management & reporting APIs | Both have APIs; AdButler includes retail-ready primitives. |
| Infra & SLO | 99.99% uptime; multi-region | Performance emphasized; public PoP/SLO specifics vary | Procurement prefers explicit SLOs. |

Frequently Asked Questions
Does Epom have self-serve for advertisers?
Epom's "self-serve" refers to their programmatic buying platform (white-label DSP). AdButler's self-serve portal is designed for your direct-sold advertisers to purchase your inventory—they can browse placements, buy campaigns, make payments, and track performance under your brand.
Can AdButler update newsletter ads after they're sent?
Yes. AdButler's Email User ID (EUID) system and ad persistence feature allow you to rotate or fix creative even after your newsletter has been delivered. Each recipient sees fresh ads when they open, and you can make updates without resending.
Do you support retail media and shoppable video?
Yes. AdButler provides ProductDB for managing product catalogs, JSON Ad API for native sponsored listings, catalog zones for targeting by product category, and VAST video with shoppable product companion cards.
Is AdButler fully white-label?
Yes. You can brand all dashboards and advertiser portals, use your own domain, and manage multiple tenants. Perfect for agencies, networks, and platforms that need a white-label solution.
What are the starting prices?
AdButler starts at $179/mo and includes core ad serving, reporting, and API access. Epom starts at $250/mo and includes their white-label DSP. Both platforms offer custom enterprise pricing for high-volume customers.
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.
Can I run both platforms during transition?
Yes. Many customers run AdButler and their existing platform in parallel during migration to minimize risk. You can gradually shift inventory and campaigns at your own pace.
Do you offer migration support?
Yes. All customers receive migration support including technical documentation, implementation guidance, and dedicated support during onboarding. Enterprise customers get assigned technical account managers for hands-on migration assistance.
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.
