How can I improve email deliverability on a shared IP for marketing automation emails like abandoned carts?

Improving email deliverability on a shared IP for marketing automation emails like abandoned carts requires a comprehensive strategy. Key elements include ensuring proper email authentication (SPF, DKIM, DMARC), gradually warming up the IP address with increasing sending volumes, and actively managing your email list. List management involves using double opt-in, segmenting audiences based on engagement, removing inactive subscribers, and promptly handling unsubscribe requests. Focus on creating wanted email beyond abandoned carts by diversifying content and personalizing messages with dynamic content and compelling offers. Monitor sending reputation within your ESP (e.g., Klaviyo) and subscribe to feedback loops to address spam complaints. Design mobile-friendly emails and avoid aggressive messaging. Remember deliverability is impacted by the behavior of others on the shared IP and your own engagement metrics signal whether you're a source of wanted or unwanted emails.

To improve email deliverability on a shared IP for marketing automation emails like abandoned carts, several strategies are recommended. These include ensuring proper authentication (SPF, DKIM), gradually warming up the IP by increasing sending volume, segmenting email lists to target engaged users, and using double opt-in to confirm subscriptions. Optimizing email content with compelling visuals, clear calls-to-action, and personalized offers is also crucial. Monitoring sending reputation metrics, promptly addressing spam complaints, and maintaining list hygiene by removing inactive users can further enhance deliverability. Mobile-friendly design and personalized dynamic content are also recommended. Additionally, it's vital to avoid aggressive or pushy messaging and to test different sending times.

Improving email deliverability on a shared IP, especially for abandoned cart emails, requires focusing on sending wanted email, authenticating your mail stream, and maintaining list hygiene. Experts recommend sending engaging content beyond abandoned carts to build a positive reputation. While a shared IP helps overcome initial legitimacy hurdles, your sending reputation is determined by recipient engagement. Authenticating with SPF and DKIM is crucial for ISPs to verify your identity. List quality is paramount; removing unengaged users and bounces improves deliverability. Throttling email sends and segmenting your audience ensure relevant messages reach those who want them. While IPv6 isn't mandatory, a valid authentication ensures mailbox providers track your mail stream reputation without relying solely on IP address.

Improving email deliverability on a shared IP requires a multi-faceted approach focused on authentication, list management, and reputation monitoring. Documentation from Google, SendGrid, Mailchimp, and SparkPost emphasizes the importance of email authentication (SPF, DKIM, DMARC) and maintaining a clean sending list to mitigate the risks associated with shared IPs. Permission-based email marketing is crucial, requiring explicit consent from subscribers and prompt honoring of unsubscribe requests. Monitoring sending reputation metrics like bounce rates and spam complaints, along with subscribing to feedback loops to receive spam complaint reports, enables proactive identification and removal of problematic subscribers.
