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.

The GIF below illustrates connecting to your DFY account and selecting a domain name, and purchasing it. For more information, refer to this document.

It is a crucial process to build a positive sender reputation with email service providers. By gradually increasing your sending volume, you allow your mailbox to gain trust and avoid being flagged as spam.

To begin, start by sending low volumes of emails daily. Over 3-4 weeks, gradually increase the number of emails sent each day. For instance, begin with 20 emails per day in week 1, then increase to 50 in week 2, and 100 by week 4. For more information, refer to this document.
​

Email authentication is essential for proving 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 and add or update the following records to authenticate your domain:

Example: Add an SPF record like v=spf1 include:spf.b2brocket.ai -all to authorize the domain to send emails on your behalf. The GIF below demonstrates how to connect to your DFY account, select a domain name, and purchase it. For more information, refer to this document.
​

Sending emails to invalid or risky addresses can damage your sender reputation and increase bounce rates. Validating your email lists before launching campaigns ensures you’re only reaching real, engaged prospects.

As shown in the GIF below, you can easily filter, mark, or stop leads for validation. For example, remove 50 flagged addresses from 1,000 emails to reduce bounce rates and protect your sender reputation.
