Your DNS records are the gatekeepers that prove your emails are legitimate
Sender Policy Framework specifies which mail servers are authorized to send email on behalf of your domain. Without it, anyone can spoof your address.
DomainKeys Identified Mail adds a cryptographic signature to every email, letting recipients verify the message wasn't altered in transit.
Domain-based Message Authentication ties SPF and DKIM together with a policy that tells receivers what to do when authentication fails.
At Email In Your Box, we believe deliverability starts at the DNS layer. While others focus on content and design, we dig into the records that actually determine whether your email reaches the inbox.
Our team has configured thousands of DNS records across hundreds of domains, turning spam-flagged senders into trusted sources. We don't just set up SPF, DKIM, and DMARC—we optimize, monitor, and evolve your authentication stack as standards change.
DNS expertise is our core differentiator. Every email that lands in the inbox starts with a DNS query, and we make sure every query returns the right answer.
