These 2 things could dramatically increase your deliverability

If you’re looking to maximize your cold email outreach, improving deliverability is key.

These two techniques: domain masking proxies and rotating IPs can significantly enhance your ability to reach recipients’ inboxes while protecting your sender reputation.

Here’s everything you need to know about these strategies, why they matter, and how to implement them effectively 👉🏻

What are domain masking proxies?

Domain masking proxies are tools that help conceal your sending domain for email campaigns. Instead of directly exposing your primary domain (e.g., yourcompany.com), domain masking uses a proxy or secondary domain (e.g., mail-yourcompany.com) to handle email traffic.

Here’s why it matters:

• Protects your primary domain’s reputation: If emails from your campaign are flagged, it’s your masked domain, not your main domain, that is affected.

• Improves deliverability: By rotating secondary domains for your campaigns, you spread out the risk of domain blacklisting.

• Easier recovery: If a masked domain is flagged, it’s easier and faster to replace it than to rehabilitate your primary domain.

What are rotating IPs?

Every email you send comes from an IP address, and mailbox providers like Gmail and Outlook track the reputation of these IPs. Sending too many emails from a single IP, especially in a short timeframe, can lead to flagging or even blacklisting.

Rotating IPs involves using multiple IP addresses to send your emails, distributing the load and reducing the risk of being flagged as spam.

Here’s why it matters:

• Avoid sending volume limits: High volumes of email traffic from a single IP can trigger spam filters. Rotating IPs keeps your volume under the radar.

• Spread risk across multiple IPs: If one IP gets flagged, others remain unaffected, preserving the overall health of your email infrastructure.

• Boost sender reputation: By rotating trusted, authenticated IPs, you maintain a consistent and positive sender reputation.

Best practices for implementing domain masking proxies and rotating IPs

1. Use multiple domains for campaigns:

   • Register several secondary domains similar to your primary one (e.g., sales-yourcompany.com or mail-yourcompany.com).

   • Authenticate all domains with SPF, DKIM, and DMARC to establish credibility with email providers.

2. Set up IP rotation with email infrastructure tools:

   • Use tools like Infraforge or Mailforge to configure and manage multiple IP addresses for sending.

   • Automate IP rotation to balance email sending evenly across all IPs.

   • Now you can also purchase additional IPs for your workspaces in Infraforge for more precise control.

   

3. Monitor and test regularly:

   • Use deliverability testing tools to ensure your emails are reaching inboxes.

   • Track metrics like bounce rates, spam complaints, and open rates for each domain and IP.

4. Warm up new domains and IPs:

   • Start sending a small number of emails initially and gradually increase volume to build a positive reputation.

5. Segment campaigns across domains and IPs:

   • Assign specific campaigns or audiences to certain domains and IPs to avoid overloading any single source.

Watch out for these pitfalls:

While these techniques are great for improving your deliverability, it’s key to always watch out for common pitfalls that can harm your outreach:

• Overusing domains/IPs: Even with rotation, sending too many emails from the same domain or IP can cause issues. Stick to gradual increases in volume.

• Neglecting authentication: Domains and IPs without proper SPF, DKIM, and DMARC authentication will be flagged as suspicious by email providers.

• Ignoring reputation monitoring: Continuously track your domains’ and IPs’ reputations to address issues before they impact deliverability.
