Is Klaviyo sending issues fixed and safe to resend emails?

Key findings

• Status page reliability: While official status pages (like Klaviyo's) are crucial, they may sometimes indicate a fix before complete stability is achieved, especially for complex issues.
• Intermittent issues: Problems like elevated hard bounce rates can be intermittent, meaning some emails might get through even during an ongoing issue, making a 'fix' seem premature.
• Monitoring period: Some experts recommend waiting 48-72 hours after an announced fix to confirm true resolution, especially if the issue has recurred. This cautious approach helps prevent further deliverability damage.
• Hard bounce spikes: Significant increases in hard bounces, particularly to major ISPs like Gmail, are a strong indicator of an active or recurring sending problem, even if the status page indicates otherwise.

Key considerations

• Verify internally: Before resuming large sends, cross-reference the ESP's status with your own internal monitoring of bounce rates and inbox placement. Utilize a robust email deliverability tester.
• Consider impact of resends: Resending emails, especially to non-openers, can sometimes harm deliverability if not done carefully and when issues persist. Review best practices for resending emails.
• Communicate with support: Engage directly with your ESP's support team for real-time updates and guidance specific to your account's sending patterns.
• Assess risk tolerance: For highly critical campaigns, a conservative waiting period might be preferable over immediate resending, even if the issue appears resolved. Understand why emails go to spam.

Key opinions

• Cautious approach: Many marketers prefer to wait a significant period (e.g., 48-72 hours) after a 'fix' is announced before fully trusting the system.
• Intermittent fixes: There's an understanding that initial 'fixes' might be temporary or partial, with issues recurring soon after.
• Personal experience over status page: Marketers tend to rely on their own real-time bounce rate monitoring and deliverability metrics more than solely on the ESP's status page.
• Varying impact: Some marketers may not experience issues or see them resolved quickly, while others continue to report problems like elevated hard bounces.

Key considerations

• Monitor your metrics: Continuously check your campaign performance, bounce rates, and engagement data for signs of lingering issues. This is key to understanding why your email deliverability rate is wrong.
• Consult ESP support: If you have an account manager or dedicated support, leverage their advice on specific sending plans, particularly for critical campaigns.
• Segment sensitive sends: For crucial emails, consider a phased re-sending approach to a small, highly engaged segment first to test the waters. This aligns with splitting sends to engaged users.
• Understand bounce types: Be aware that elevated hard bounces (permanent failures) are more concerning than soft bounces (temporary issues), indicating a potentially deeper underlying problem with the sending infrastructure or recipient servers.

Key opinions

• Stability window: Experts emphasize the need for a sustained period (e.g., 2-3 days) of no reported issues before confidently declaring a resolution.
• Deep-seated issues: Some problems might be indicative of deeper, structural issues rather than simple fixes, requiring a 'patch and observe' approach that can lead to recurring problems.
• Data-driven trust: While ESPs monitor their data closely, external experts might look for a longer trend of stability before advising clients to fully resume normal operations.
• Postmaster communication: Insights from Postmaster communities (like Mailop) can provide a more granular view of ongoing issues, even if not directly reflected on status pages.

Key considerations

• Long-term reputation impact: Repeated sending during an unstable period can negatively impact your sender reputation, making it harder to recover even after the ESP's issues are fixed. Understand how to recover your email domain and IP reputation.
• ISP feedback: Monitor feedback loops and Postmaster tools (like Google Postmaster Tools
• ) for direct signals from ISPs about your sending health.
• Root cause analysis: For recurring issues, an expert might delve into the root cause beyond surface-level symptoms, such as SPF, DKIM, or DMARC misconfigurations, to prevent future occurrences. Learn about DMARC, SPF, and DKIM
• Alternative sending plans: Having contingency plans or backup sending methods can mitigate risk during prolonged ESP outages or intermittent issues, as suggested by deliverability experts

Key findings

• Deliverability hub: Platforms like Klaviyo provide a 'Deliverability hub' for analyzing and diagnosing account-level email health, suggesting that users should actively use these tools.
• Troubleshooting resources: Documentation often includes extensive troubleshooting guides for common issues, including emails going to spam or template errors.
• Resend functionality: ESPs provide mechanisms to resend emails, but the documentation implies this is a user-initiated action that should be used judiciously.
• Data discrepancies: Documentation may offer solutions for discrepancies between platform data and external analytics, highlighting the complexity of tracking.

Key considerations

• Leverage internal tools: Rely on your ESP's deliverability tools and reports to understand your specific account's health rather than assuming system-wide issues are resolved for everyone.
• Review troubleshooting guides: Consult official troubleshooting articles, especially if you encounter error messages or persistent issues. This can help you identify whether outlook email deliverability issues are resolved.
• Understand ESP limitations: While ESPs strive for high deliverability, the ultimate success of an email depends on numerous factors beyond their control, including recipient ISP filters and sender reputation, so monitor your blocklist monitoring.
• Support contact points: Familiarize yourself with the available support channels and their typical response times, especially for urgent deliverability concerns.
