Can Proofpoint implementation and MX record changes during IP warming affect email deliverability?
Summary
What email marketers say8Marketer opinions
Email marketer from GMass Blog shares that your email is only as good as your sending reputation. Make sure to not send spam and try your best to clean your email list.
Email marketer from SendGrid Blog explains that a gradual IP warming schedule is essential to establish trust with ISPs. Suddenly increasing sending volume from a new IP can trigger spam filters. It's important to start with small volumes to engaged users and gradually increase the number of emails sent over time.
Email marketer from Litmus Blog responds that its essential to monitor your deliverability. Look for common issues such as a decreased inbox placement, an increase in spam complants, and an increase in hard bounces.
Email marketer from Email Geeks shares a proposal to change the manager's mind about using subdomains, create new sending subdomains for each mailstream, and adjust SPF records. Differentiating sending domains by mailstream allows each stream to hold its own reputation, which is especially important at Gmail. If there's a domain reputation issue, identifying the problematic mailstream is easier with separate subdomains. It's also mentioned that the deliverability problem might be related to targeting a less engaged population during the IP warming process.
Email marketer from Email on Acid Blog shares that proper setup of DKIM, SPF, and DMARC is critical for email deliverability. Changes to email infrastructure may require updates to these records. Incorrect settings will hurt your deliverability.
Email marketer from Reddit shares that any DNS changes including MX records require time to propagate across the internet. This period varies, but generally, it takes 24-48 hours for full propagation. During this time, some recipients might still be using the old MX records, leading to temporary delivery failures.
Email marketer from Mailjet Blog shares that changing email infrastructure, such as implementing a security solution like Proofpoint, can affect deliverability. Monitoring key metrics like bounce rates and engagement is important. Sudden drops in engagement post-implementation can signal deliverability issues.
Email marketer from Neil Patel's Blog shares that IP warming is a critical process to establish a positive sending reputation with ISPs. A sudden spike in email volume from a new IP address without proper warming can negatively impact deliverability, leading to emails being marked as spam. It's important to gradually increase sending volume and maintain consistent sending habits.
What the experts say3Expert opinions
Expert from Spam Resource explains that changing MX records can indeed affect deliverability, especially during IP warming. Incorrectly configured or propagated MX records can lead to temporary or permanent delivery failures. It's crucial to monitor email flow and verify that the new MX records are functioning correctly.
Expert from Word to the Wise responds that changing mail servers or implementing new security tools like Proofpoint can impact your sender reputation and thus deliverability. She advises closely monitoring deliverability metrics and adjusting configurations as necessary.
Expert from Email Geeks explains that Proofpoint implementation and MX record changes during IP warming could impact deliverability as MBPs might track these changes. It's suggested to verify SPF, DKIM, and other authentication setups to ensure they didn't break during the changeover.
What the documentation says5Technical articles
Documentation from Amazon Web Services responds that to improve your email deliverability, ensure you authenticate your emails with SPF, DKIM and DMARC. Make sure you are sending quality content, and handle bounces and complaints.
Documentation from Microsoft Learn explains that MX records are crucial for directing email flow to your mail server. Changes to MX records can temporarily disrupt email delivery if not propagated correctly, and it's important to ensure the new MX records are properly configured and propagated before removing the old ones to avoid delivery issues.
Documentation from Google Postmaster Tools explains that Gmail considers domain reputation when filtering emails. Significant changes to sending practices, infrastructure, or authentication without proper warming or communication can negatively impact your domain's reputation, leading to deliverability issues. Monitor domain reputation in Postmaster Tools to track deliverability health.
Documentation from Proofpoint Support explains that Proofpoint's primary function is to filter and protect against malicious emails. While it enhances security, misconfigured Proofpoint settings or overly aggressive filtering rules can inadvertently block legitimate emails, affecting deliverability. Proper configuration and monitoring are essential.
Documentation from RFC explains that SPF records have a limit of 10 DNS lookups. Exceeding this limit can cause SPF authentication to fail, negatively impacting deliverability. It's essential to optimize SPF records and stay within the lookup limit.
