Summary
Implementing Proofpoint, changing MX records, and undergoing IP warming are significant infrastructure changes that can impact email deliverability. Mailbox providers may track these changes. Gradual IP warming is crucial for establishing a positive sending reputation, and sudden volume spikes can trigger spam filters. DNS changes, especially MX records, require propagation time, leading to temporary delivery failures. Proper setup and maintenance of DKIM, SPF, and DMARC are critical, with updates needed after infrastructure changes. Monitoring key metrics like bounce rates, engagement, and inbox placement is essential for identifying deliverability issues. Sender reputation is paramount, necessitating careful list management and avoiding spam-like practices. Utilizing subdomains for different mail streams can help manage reputation, especially with Gmail. Proper configuration and monitoring of Proofpoint are essential to avoid blocking legitimate emails. Exceeding SPF record lookup limits can cause authentication failures. Sending quality content and handling bounces/complaints also contribute to deliverability.

What the experts say
3 expert opinions
Implementing Proofpoint and changing MX records during IP warming can impact email deliverability due to potential tracking by Mailbox Providers (MBPs), possible misconfiguration, and effects on sender reputation. It's crucial to verify SPF, DKIM, and other authentication settings, monitor email flow, and adjust configurations as necessary to mitigate negative impacts.
Key opinions
- MBP Tracking: Mailbox Providers (MBPs) might track changes to MX records and Proofpoint implementation, influencing deliverability.
- Misconfiguration Risks: Incorrectly configured MX records can lead to temporary or permanent delivery failures.
- Reputation Impact: Implementing new security tools or changing mail servers can affect sender reputation and, consequently, deliverability.
Key considerations
- Authentication Verification: Verify that SPF, DKIM, and other authentication setups are correctly configured and haven't broken during the changeover.
- Monitoring Email Flow: Closely monitor email flow to identify and address any delivery issues caused by MX record changes.
- Configuration Adjustments: Be prepared to adjust Proofpoint and other security tool configurations based on deliverability metrics.

What the documentation says
5 technical articles
Changes to email infrastructure, such as MX records or implementing Proofpoint, and the process of IP warming can affect email deliverability. MX records direct email flow, and incorrect propagation can disrupt delivery. Proofpoint, while enhancing security, can block legitimate emails if misconfigured. Gmail considers domain reputation, and changes without proper warming can negatively impact it. SPF records have lookup limits that must be adhered to. Proper authentication with SPF, DKIM, and DMARC is crucial for deliverability, as is sending quality content and handling bounces/complaints.
Key findings
- MX Record Impact: Improperly propagated MX record changes can disrupt email delivery.
- Proofpoint Configuration: Misconfigured Proofpoint settings can inadvertently block legitimate emails.
- Domain Reputation: Significant infrastructure changes without proper warming can negatively impact domain reputation with Gmail.
- SPF Lookup Limits: Exceeding the SPF record lookup limit can cause authentication failures and impact deliverability.
- Authentication Importance: Proper authentication with SPF, DKIM, and DMARC is crucial for email deliverability.
Key considerations
- MX Record Propagation: Ensure new MX records are properly configured and propagated before removing old ones.
- Proofpoint Monitoring: Properly configure and monitor Proofpoint settings to avoid overly aggressive filtering.
- Monitor Domain Reputation: Monitor domain reputation using Google Postmaster Tools.
- Optimize SPF Records: Optimize SPF records to stay within the lookup limit.
- Content Quality: Send high-quality content and properly handle bounces and complaints to maintain a positive sender reputation.
