Effectively managing your email accounts is essential for the success of your B2B cold email outreach. Following best practices for buying, configuring, warming up, authenticating mailboxes, and validating email lists ensures your campaigns reach your prospects' inboxes and achieve optimal results.

Let’s get started 🚀

Using dedicated DFY domains and mailboxes protects your primary business domain from being blacklisted or flagged as spam. This approach ensures brand credibility, maximizes deliverability, and keeps your main domain reputation safe during cold outreach.

Note: If you prefer owning your domains, avoid using your primary domain (e.g., yourcompany.com). Instead, buy related domains like yourcompanyhq.com or yourcompanymail.com to isolate outreach activity and protect your main domain reputation.

Email authentication proves to recipients and email providers that your emails are legitimate and not spoofed. Properly configuring SPF, DKIM, and DMARC records helps improve inbox placement and protects your domain’s reputation.

Access your domain’s DNS settings via your domain registrar (GoDaddy or Namecheap), and add a TXT record with the below Host and Value.

​

Warming up your mailbox is essential for building a strong sender reputation with email service providers (ESPs). This process involves gradually increasing your daily email sending volume to gain trust and reduce the risk of being flagged as spam.

Start with a low number of emails—around 20 per day in the first week—and slowly ramp up over a few weeks. For more on how you customize your sending schedule, refer to this document.
