Summary
The challenge of managing email block bounces, particularly from major providers like Yahoo and AOL, within Salesforce Marketing Cloud (SFMC) has become more pronounced with recent policy changes. When emails are erroneously blocked or bounce due to perceived issues, it directly impacts deliverability and engagement. The core issue revolves around regaining access to these recipient inboxes and rectifying any reputation damage. This often requires understanding the nuanced reasons for the blocks and navigating the specific processes set by both SFMC and the internet service providers (ISPs).
Key findings
- Recent policy impact: New Gmail and Yahoo policies have led to an increase in block bounces and inbox placement issues for some senders, particularly affecting Yahoo and AOL domains.
- SFMC involvement: Salesforce Marketing Cloud typically handles IP blocks and unblocking requests directly with ISPs. Customers are generally not expected to perform these actions themselves.
- Address reactivation: Reactivating addresses that have been set to 'unbounced' within SFMC, especially after a block, requires opening a support ticket as it's a controlled process for deliverability reasons.
- IP reputation influence: A poor reputation on one dedicated IP can potentially impact the deliverability of other IPs, especially if they are part of the same mailstream or domain (or sending patterns are similar).
- Diagnosing issues: Monitoring tools, such as SFMC's built-in reports or external platforms, are crucial for identifying specific bounce reasons and affected domains.
Key considerations
- Engage SFMC support: For actual IP block removal or mass reactivation of bounced addresses, submit a support ticket to Salesforce Marketing Cloud. They have the direct channels and processes for these actions.
- Understand bounce types: Distinguish between temporary (soft) and permanent (hard) bounces. Persistent hard bounces, particularly 'block bounces,' indicate a more severe deliverability issue requiring intervention. For more details on these issues, review how to resolve persistent block bounces with Yahoo/AOL.
- Proactive reputation management: Maintain high sender reputation by adhering to best practices like list hygiene, sending relevant content, and authenticating emails properly (SPF, DKIM, DMARC).
- Monitor deliverability: Continuously monitor inbox placement and bounce rates. Salesforce provides tools for bounce management, but external monitoring can offer deeper insights.This guide from Email Uplers delves into SFMC bounce management and analysis.
What email marketers say
Email marketers using Salesforce Marketing Cloud have voiced significant concerns and frustrations regarding recent increases in block bounces, particularly affecting Yahoo and AOL email addresses. The consensus points to the impact of new email policies implemented by these major mailbox providers. Marketers often find themselves in a reactive state, observing higher hard bounce rates and diminished inbox placement, and seeking immediate solutions to restore email flow to affected subscribers.
Key opinions
- Sudden increase in bounces: Many marketers observed a rapid increase in hard bounces from Yahoo and AOL, coinciding with the rollout of new sender requirements.
- Impact on inbox placement: Reports indicate that overall inbox placement suffered, with these bounces being a primary indicator of deliverability issues.
- SFMC as primary point of contact: Marketers frequently acknowledge that resolving IP-level blocks and reactivating addresses is a process primarily managed by SFMC support, rather than being a self-service option.
- Challenge with mass reactivation: There is a perceived difficulty in reactivating hundreds of bounced addresses that might have been marked in error, highlighting a need for a streamlined solution.
Key considerations
- Identify block origin: Determine if the issue is an actual IP block or simply addresses marked as 'bounced' due to other deliverability failures. Salesforce Marketing Cloud bounce data can help pinpoint this, though additional analysis might be needed. If Yahoo and AOL are consistently bouncing, you may want to review why your emails are bouncing.
- Review SFMC bounce management: Familiarize yourself with Salesforce Marketing Cloud's bounce management practices. Understanding how SFMC handles bounces is key to diagnosing and resolving these issues effectively.
- Dedicated IP implications: For senders with multiple dedicated IPs per domain, it's important to recognize that reputation issues on one IP can influence others, emphasizing the need for consistent positive sending behavior across all streams.
- Address underlying causes: While SFMC can unblock, preventing future blocks requires addressing the root causes, such as list quality, content relevance, and sending frequency.
Marketer view
Email marketer from Email Geeks indicates that they are experiencing persistent issues with Yahoo and AOL email bounces and blocks in Salesforce Marketing Cloud. They noted that their inbox placement and hard bounce rates were predominantly from these two providers after recent policy changes.
Marketer view
An email marketer from Email Geeks suggests that opening a ticket with Salesforce Marketing Cloud (SFMC) is the most likely way to resolve block bounces. They believe SFMC handles such requests internally and discourages customers from attempting to resolve these issues themselves.
What the experts say
Deliverability experts emphasize that email block bounces, particularly from major ISPs like Yahoo and AOL, are direct indicators of reputation issues or non-compliance with sender best practices. They advocate for a multi-faceted approach that combines technical adherence to authentication standards (DMARC, SPF, DKIM), meticulous list management, and proactive engagement with ISPs. Experts highlight that Salesforce Marketing Cloud users must leverage the platform's capabilities effectively while understanding its limitations in direct IP management.
Key opinions
- Authentication is paramount: Experts stress that proper implementation of DMARC, SPF, and DKIM is non-negotiable for deliverability, especially with new Yahoo and AOL policies.
- Reputation is dynamic: IP and domain reputation are continuously assessed by ISPs. Any deviation from good sending practices can lead to blocks, even on previously clean IPs.
- List hygiene prevents problems: Aggressive list cleaning, including removing inactive subscribers and managing bounces, is critical to prevent blocklisting. For a deeper understanding of this, consider a practical guide to understanding your email domain reputation.
- ISPs manage unblocking: Direct removal from blocklists (or blocklists) for shared or managed IPs is handled by the ESP (like SFMC) and the ISP, not typically the end-user.
Key considerations
- Monitor DMARC reports: Analyze DMARC reports from Google and Yahoo to gain visibility into authentication failures and potential alignment issues that could lead to blocks. Discover how to gain further insights into DMARC reports from Google and Yahoo.
- Segment mailstreams: Separate transactional, marketing, and highly engaged mailstreams to isolate potential issues and protect overall sending reputation.
- Complaint rate management: High complaint rates are a major trigger for blocks. Implement feedback loops and clearly visible unsubscribe options.
- Postmaster tool usage: Utilize Yahoo's and AOL's postmaster tools (where available) to access insights into your sending reputation and potential blocklisting status directly from the source.
Expert view
Deliverability expert from Email Geeks advises that achieving high deliverability to Yahoo and AOL now critically depends on strict adherence to the new sender requirements, particularly regarding DMARC authentication. They noted that simply having SPF or DKIM is no longer sufficient to guarantee inbox placement.
Expert view
An expert from Email Geeks suggests that maintaining a low spam complaint rate is essential for avoiding blocks from major mailbox providers. They emphasize that even a small percentage of complaints can trigger automated blocking mechanisms.
What the documentation says
Official documentation from email service providers (ESPs) like Salesforce Marketing Cloud and internet service providers (ISPs) such as Yahoo and AOL outlines stringent requirements for email senders. These documents underscore the importance of proper email authentication, maintaining low complaint rates, and adhering to strict anti-spam guidelines. They also detail the procedures for managing bounces and the circumstances under which IPs or domains may be blocklisted, often placing the responsibility for remediation on the ESP rather than the end-user.
Key findings
- Authentication standards: Documentation from Yahoo and AOL clearly states the necessity of DMARC, SPF, and DKIM authentication for all senders, particularly for bulk senders.
- Complaint threshold: ISPs set specific complaint thresholds (e.g., 0.3% for Yahoo/AOL). Exceeding these thresholds can lead to immediate deliverability penalties, including blocks.
- One-click unsubscribe: New policies mandate easily accessible one-click unsubscribe mechanisms, which must be clearly visible and functional for all commercial emails.
- Bounce processing in SFMC: Salesforce Marketing Cloud documentation details its automated bounce management system, which categorizes bounces and automatically suppresses addresses after a certain number of hard bounces.
Key considerations
- Adhere to sender requirements: Review and strictly follow the latest sender requirements published by major mailbox providers, such as those from Yahoo and AOL. This includes authentication, content, and list management. Ensure your DMARC, SPF, and DKIM are properly configured.
- Monitor deliverability metrics: Utilize SFMC's reporting features to track bounce rates, complaint rates, and deliverability to specific domains. High bounce rates to Yahoo can indicate a need to fix Yahoo deliverability issues.
- Maintain list hygiene: Regularly clean subscriber lists to remove invalid, inactive, or unengaged addresses. This minimizes hard bounces and reduces the risk of hitting spam traps.
- Postmaster tool engagement: Register domains with Yahoo and AOL Postmaster tools to access vital data, including reputation status, feedback loop data, and potential blocklist entries.
Technical article
Yahoo's Postmaster Guidelines emphasize that bulk senders must authenticate their emails with DMARC, SPF, and DKIM to ensure deliverability. They state that unauthenticated mail is more likely to be filtered or rejected.
Technical article
AOL's Postmaster documentation stipulates that maintaining a low spam complaint rate is critical for good sender reputation. They advise that complaints signal unwanted mail and can lead to blocking of future messages.
