Summary
For many years, Return Path (now part of Validity) was a dominant force in email deliverability certification, offering a certification program that aimed to give senders an edge in inbox placement. However, the landscape of email deliverability has evolved significantly. While some regional or specialized alternatives exist, a direct, universally recognized substitute for Return Path's broad certification program is largely absent today. The focus has shifted from paid certifications towards a more holistic approach centered on sender reputation, technical compliance, and engagement metrics. Broadly speaking, there are no like-for-like global alternatives.
Key findings
- Limited global alternatives: There is no single, universally recognized certification program that directly replaces Return Path's former global influence.
- Regional certifications: Some region-specific accreditations, such as CSA certification for Germany, offer localized benefits. ItaliaOnline also has a specialized, albeit beta, program for Italian ISPs.
- ISP whitelisting decline: ISPs have largely moved away from offering their own dedicated whitelisting programs, making third-party certifications less impactful than in the past.
- Focus on reputation: Email deliverability today relies more on maintaining a strong sender reputation through consistent performance, engagement, and adherence to best practices rather than relying on a single certification.
- Holistic approach: Marketers should prioritize a comprehensive deliverability strategy that includes proper authentication (SPF, DKIM, DMARC), list hygiene, and engaging content. EmailTooltester provides an overview of various tools that can assist with this.
Key considerations
- Regional relevance: Evaluate if a regional certification, like CSA, is beneficial based on your target audience's geographical concentration.
- Cost vs. impact: Assess the return on investment for any accreditation program, considering that direct whitelisting benefits are less prevalent today.
- Beyond certification: Invest in fundamental deliverability practices, such as reputation validation, rather than seeking a single certification as a silver bullet.
- Data-driven decisions: Utilize analytics and feedback loops to understand your current inbox placement and identify areas for improvement.
What email marketers say
Email marketers often find themselves in a challenging position when seeking alternatives to well-established services like Return Path. The general consensus suggests a shift away from singular certification programs towards a more diversified strategy involving various tools and best practices. Marketers emphasize the importance of regional relevance for specific certifications and the ongoing need to monitor and optimize email performance through other means.
Key opinions
- Limited direct alternatives: Many marketers express that there aren't direct, global alternatives that replicate the comprehensive nature of Return Path's certification.
- Regional focus: CSA certification is frequently mentioned as a viable option for those primarily sending to German-speaking markets.
- Emerging niche options: ItaliaOnline's beta program for Italian ISPs is cited as an example of localized, evolving accreditation models.
- ISIPP SuretyMail: Some marketers are aware of ISIPP SuretyMail as an alternative, though its impact and reach are sometimes questioned.
- Shift in strategy: The focus is increasingly on overall deliverability performance rather than reliance on a single certification for inbox placement.
Key considerations
- Geographic targeting: Consider if a specific regional certification aligns with your primary audience, as global benefits are limited.
- Impact uncertainty: Be mindful that the perceived impact of smaller accreditation services may vary and might not be as significant as once promised by large players.
- Comprehensive monitoring: Focus on a robust suite of tools for tracking email deliverability, including inbox placement, spam trap hits, and blocklist presence, rather than relying solely on certification status.
- Engagement metrics: Prioritize user engagement and list quality, as these factors are increasingly important for inbox placement across major mailbox providers.

What the experts say
Experts in email deliverability offer a nuanced view on alternatives to Return Path's certification. While acknowledging the historical significance of such programs, they largely concur that the efficacy of broad, third-party whitelisting has diminished. Their advice tends to steer towards foundational deliverability principles, direct sender-receiver relationships, and robust technical configurations as the primary drivers of inbox placement today.
Key opinions
- No true global equivalent: Experts assert that a direct, global alternative to Return Path's certification with similar widespread recognition simply does not exist.
- Decline of ISP whitelisting: ISPs no longer maintain or offer their own versions of whitelisting programs, making external certifications less relevant for direct inboxing.
- Regional exceptions: CSA certification is recognized as a valid regional program, particularly impactful for senders targeting Germany.
- Focus on fundamentals: The emphasis is now on core deliverability practices, including maintaining a strong domain reputation and robust email authentication.
- ISIPP/SuretyMail: While ISIPP offers an accreditation service, experts advise evaluating its actual impact on deliverability as it might not carry the same weight as historical programs.
Key considerations
- Holistic reputation management: Prioritize building a positive sender reputation through consistent sending, low complaint rates, and high engagement.
- Technical compliance: Ensure proper implementation of email authentication protocols like SPF, DKIM, and DMARC. Tools for DMARC monitoring are increasingly vital.
- Audience engagement: Focus on sending relevant content to engaged subscribers to improve inbox placement metrics observed by mailbox providers.
- Industry trends: Stay informed about shifts in mailbox provider policies and algorithms, as these dictate deliverability more than third-party certifications. ISIPP's perspective on being a true alternative can offer some insights.
Expert view
Expert from Email Geeks asserts that there are no direct global alternatives to Return Path for comprehensive certification. They emphasize that the landscape for such broad, influential programs has fundamentally changed, leaving a gap for universal whitelisting.
Expert view
Expert from Email Geeks indicates that ISPs no longer offer their own whitelisting programs. This means the traditional avenues for direct accreditation from mailbox providers have closed, reinforcing the idea that paid certifications are less impactful.
What the documentation says
Official documentation from mailbox providers and industry standards typically focuses on technical compliance and sender behavior rather than proprietary certification programs. While Return Path's services were often integrated into the ecosystem, the underlying mechanisms for deliverability are rooted in protocols like SPF, DKIM, and DMARC, as well as real-time reputation signals. The emphasis from these sources is on a sender's consistent adherence to best practices and the integrity of their email streams.
Key findings
- Protocol importance: Technical documentation consistently highlights the critical role of email authentication standards (SPF, DKIM, DMARC) for deliverability.
- Return-Path domain: The Return-Path domain is primarily described in terms of bounce handling and routing, and its alignment with SPF and DMARC, rather than certification status. Klaviyo's help center provides details on how the Return-Path domain functions.
- Sender reputation metrics: Documentation emphasizes that mailbox providers evaluate sender reputation based on engagement, complaint rates, spam trap hits, and overall sending behavior.
- Compliance over certification: The focus in documentation is often on adhering to industry best practices and technical specifications to ensure deliverability, rather than relying on a third-party certification.
Key considerations
- Implement DMARC: Ensure your DMARC policy is correctly configured and monitored, as it is a key factor for mailbox providers in assessing sender legitimacy.
- Optimize Return-Path: While not a certification, ensuring your Return-Path settings are correct is crucial for proper bounce handling and authentication alignment.
- Monitor blocklists: Regularly check major blocklists (blacklists), as listings can severely impact deliverability regardless of any certification.
- Review technical guides: Consult technical documentation from major mailbox providers to understand their specific requirements and recommendations for deliverability.
