Domain Setup and Management

The foundation of your email infrastructure begins with your domain. Here are key steps:

• Purchase dedicated domains for your email campaigns. Tools like Mailscale can help generate AI-suggested domain names that align with your brand.
• Use multiple domains to spread risk. If one domain experiences issues, others can continue operating.
• Redirect your new domains so that visitors will land on your official company site.

Email Authentication Protocols

Implementing email authentication protocols is crucial for establishing sender legitimacy:

• Set up SPF (Sender Policy Framework) to specify which IP addresses are authorized to send emails from your domain.
• Implement DKIM (DomainKeys Identified Mail) to add a digital signature to your emails, verifying their authenticity.
• Enable DMARC (Domain-based Message Authentication, Reporting, and Conformance) to protect against email spoofing and phishing attempts.

Tools like Mailscale or Instantly can automate the setup of SPF and DKIM, simplifying this technical process.

Email Service Providers (ESPs) and Diversification

Don’t put all your eggs in one basket:

• Mailscale allows you to generate 50-100 emails at a time, then add them to your email sending tool with a single click.
• Alternatively, you can use a mix of Gmail and Outlook emails and add them to an email service provider like Smartlead or Instantly using their bulk upload feature.
• Use multiple email addresses per domain (e.g., sales1@domain.com, sales2@domain.com).
• Keep sending volumes low per address, ideally around 30 emails per day.

Email Warmup and Reputation Building

Gradually build your sender reputation:

• Start with low volumes and slowly increase over time.
• Automated warmup tools are included in Mailscale, SmartLead, and Instantly to simulate natural email activity.
• Use targeted content to encourage engagement. Clay is an excellent tool for doing company research at scale and creating custom content using AI.

Content Optimization for Deliverability

Craft your emails to bypass spam filters:

• Utilize spintax to create variations in your content, reducing repetition. Pitchlane has a free AI tool to help with this, along with customized video content.
• Avoid known spam trigger words, like “free” or “buy now”.
• Personalize your content for each recipient. Tools like Clay can assist with this at scale.

Monitoring and Compliance

Regularly check your email performance:

• Monitor your domain and IP reputation, checking for any blocklist inclusions.
• Use email lead generation tools like Ocean.io, FullEnrich or ListKit to make sure you are only sending to targeted leads with validated email addresses.
• Adhere to CAN-SPAM, GDPR, and other relevant email regulations.
• Maintain list hygiene by regularly cleaning your email lists. Listkit can help with both lead generation and list management.

Conclusion

Building a robust email infrastructure is crucial for successful B2B outreach. By implementing these best practices and leveraging the right tools, you can significantly improve your email deliverability, ensuring your messages reach your prospects’ inboxes.

Remember, email infrastructure is not a set-it-and-forget-it task. Continuously monitor, test, and optimize your setup to stay ahead of changing email algorithms and maintain high deliverability rates.
