Mailgun and Red Sift partner to boost email programs with stronger authentication  

Senders know that email is a critical channel for driving customer engagement and establishing trust, yet deliverability and security issues can disrupt email programs. Mailgun, a leader in cloud-based email delivery, is providing free DMARC reporting for all Mailgun senders courtesy of Red Sift OnDMARC. This integration brings senders complete visibility into authentication results and optimized sender programs.

What this means for senders

Even the most well-crafted email programs can be compromised by poor email authentication, leading to phishing attacks, brand impersonation, and deliverability issues.

Email authentication ensures that an email is genuinely sent from the domain it claims to come from. Without it, cybercriminals can spoof an organization’s domain, damaging a brand’s reputation and making it harder for real emails to land in inboxes. 

DMARC has become a standard tool for email providers like Yahoo and Google to verify sender authenticity and manage inbox placement. By reducing the risk of spoofing and ensuring emails meet industry standards, senders can achieve higher engagement rates and a better overall return on your email investments.

“This industry first, step forward acknowledges the importance of education and scalably addressing the needs of senders to respond to the rapid changes in email policies and emerging threats to the email ecosystem.”

DMARC reporting benefits for Mailgun customers

Mailgun’s new free DMARC reporting gives clear, actionable insights into email performance. It shows the total emails sent, DMARC compliance percentages, and details on emails that passed authentication, failed, were quarantined, or rejected, along with the sending IPs. This straightforward data helps senders quickly spot issues and optimize programs, ultimately boosting inbox placement and email ROI.

“Our integration with Red Sift OnDMARC simplifies email security for all Mailgun customers. Providing DNS records on a single page makes implementation straightforward for teams of any technical level, and this partnership will help defend against email spoofing, improve deliverability, and best of all – protect brands.”

Upgrade to Red Sift OnDMARC: Turning reports into results

By upgrading from Mailgun’s free reporting to Red Sift OnDMARC, senders can instruct receiving mail servers to outright reject emails that fail authentication. In doing so, senders can reach more inboxes, reduce bounces, and build trust.

  • Stop Spoofers: Actively block fraudulent senders instead of just tracking them.
  • All-in-One Management: Manage SPF, DKIM, DMARC and MTA-STS from one place to ensure every message is authenticated. Make a one time update to DNS and never make a change request again.
  • Display your logo in the inbox: Reach DMARC enforcement to display a logo in recipients’ inboxes with Brand Indicators for Message Identification (BIMI), strengthen credibility, and drive higher engagement on email programs.
  • Expert Support: Get help from a team trusted by thousands to guide email security efforts.
  • Use AI to automate manual tasks: Get LLM powered actionable insights to close security gaps before they can be exploited.
