How does Salesforce Marketing Cloud handle email bounces and what are the best practices for bounce management?

Summary

Salesforce Marketing Cloud offers automated bounce processing, classifying emails as hard or soft bounces and updating subscriber statuses accordingly. While SFMC has a default multi-bounce suppression policy, many experts advocate for more aggressive, immediate hard bounce suppression to protect sender reputation. Effective bounce management extends beyond automation, requiring proactive list hygiene, deep data analysis using SFMC's tools, and a nuanced approach to differentiate bounce types. Leveraging SFMC's data views and APIs allows marketers to gain critical insights into bounce trends, identify problematic domains, and refine their list segmentation, ultimately contributing to better deliverability and a healthier sender reputation.

Key findings

  • Automated Bounce Processing: Salesforce Marketing Cloud automatically processes email bounces, classifying them as hard or soft, and updates subscriber statuses accordingly. Hard bounces typically lead to an 'Undeliverable' status, while multiple soft bounces can also result in suppression.
  • Default Bounce Policy Criticized: SFMC's standard bounce policy often involves a threshold, such as 'at least 3 bounces where at least 2 weeks pass between bounces 1 and 3.' This default logic has been criticized by experts for being too slow, potentially allowing numerous sends to invalid addresses before suppression.
  • Need for Nuanced Approach: Email deliverability experts emphasize that bounce management requires a 'scalpel' approach rather than a 'hammer,' highlighting the need for more nuanced strategies beyond SFMC's default settings and the importance of understanding specific bounce types and reasons.
  • Data Views for Deep Analysis: SFMC provides data views like `_Bounce` and `_Sent`, as well as REST APIs, allowing users to query detailed information about individual bounces and send logs. This data is crucial for advanced analysis, custom reporting, and integrating with external systems for holistic insights.
  • High Bounces Signal Poor Quality: Even with automated handling, high bounce rates indicate underlying issues with list quality or sending practices. Proactive management and ongoing list cleaning are essential to ensure messages reach their intended recipients and maintain a positive sender score.

Key considerations

  • Aggressive Hard Bounce Suppression: Prioritize immediate suppression of hard bounces, often referred to as 'one and done,' rather than relying solely on Salesforce Marketing Cloud's default multi-bounce suppression policy. Experts strongly recommend submitting a ticket to SFMC to implement this more aggressive approach for hard bounces.
  • Proactive List Hygiene: Implement continuous and proactive list hygiene practices, including double opt-in, regular removal of inactive or unengaged subscribers, and setting up automations to clean soft bounced addresses after a certain threshold. This minimizes overall bounce rates and protects sender reputation.
  • Leverage SFMC Data Tools: Utilize SFMC's `_Bounce` data view, REST API, and Automation Studio for advanced bounce management. This enables detailed analysis of bounce types, reasons, and trends; identifying problematic domains; and informing segmentation and custom suppression logic beyond SFMC's automated handling.
  • Differentiate Bounce Types: Clearly distinguish between hard and soft bounces. While hard bounces necessitate permanent suppression, soft bounces may warrant a re-engagement strategy if temporary issues caused the bounce, though repeated soft bounces should also lead to suppression.
  • Impact on Sender Reputation: Understand that even with SFMC's automated bounce processing, consistently high bounce rates signal poor list quality to Internet Service Providers (ISPs), negatively impacting overall sender reputation and deliverability, especially during IP warming.

What email marketers say

16 marketer opinions

Building on its automated bounce handling, Salesforce Marketing Cloud requires a strategic, hands-on approach to truly optimize deliverability. While the platform categorizes and processes bounces, a common critique is its default multi-bounce policy, which experts often find too lenient. Successful bounce management in SFMC isn't just about the system suppressing addresses; it demands ongoing proactive list hygiene, diligent monitoring of bounce data through dedicated data views, and the implementation of custom logic to ensure immediate suppression of hard bounces. This meticulous attention helps maintain a strong sender reputation and ensures messaging reaches engaged subscribers, preventing unnecessary outreach to invalid addresses.

Key opinions

  • SFMC's Default Logic: Salesforce's standard bounce policy involves a multi-bounce threshold, often 'at least 3 bounces where at least 2 weeks pass between bounces 1 and 3,' which can allow up to 15 messages for daily mailers before suppression.
  • Criticism of Default Reasoning: Experts question Salesforce's default bounce logic, particularly the claim that only large companies should set up immediate hard bounce removal, arguing this approach is generally suboptimal.
  • Nuanced Terminology: The generic term 'bounces' is insufficient; effective discussions and management require clear differentiation between 'hard bounces' and 'soft bounces' to guide appropriate actions.
  • Proactive Monitoring: Beyond SFMC's automatic handling, proactively monitoring bounce rates using data views like _Bounce and _Sent is critical for identifying trends and high bounce domains, informing list cleaning efforts.
  • Beyond Automation: Effective bounce management in SFMC extends beyond automated processing to include proactive list hygiene, such as double opt-in and regular removal of unengaged subscribers, to prevent high bounce rates from negatively impacting sender score.

Key considerations

  • Customizing Hard Bounce Logic: Strongly consider configuring SFMC to implement a 'one and done' hard bounce logic. This often requires submitting a support ticket to Salesforce Marketing Cloud, ensuring hard bounced addresses are immediately marked as inactive rather than unsubscribed.
  • Utilize Data for Analysis: Regularly extract and analyze SFMC bounce data from _Bounce and _Sent data views using SQL queries or external tools. This enables deeper custom analysis, trend identification, and cross-referencing with CRM data for a holistic view of deliverability issues.
  • Re-engagement for Soft Bounces: Develop a strategic approach for soft bounces. While hard bounces demand permanent suppression, soft bounces, often due to temporary issues, might warrant a re-engagement path before permanent suppression if they recur.
  • Automation for Bounce Management: Leverage SFMC's automation capabilities, like Automation Studio, to create journeys or programs that automatically respond to bounce events, such as moving hard-bounced subscribers to a 'Do Not Send' list and tracking soft bounces over time.
  • Sender Reputation Protection: Recognize that high bounce rates, even if automatically managed, send negative signals to ISPs and can significantly impact sender reputation, especially during IP warming. Rigorous list cleaning and careful segmentation are paramount.
