Improve delivery
White label email services for your email marketing
Mailgun’s white label email service emphasizes deliverability. ISPs work hard to protect users from spam emails by reviewing message headers and message content for indicators that the sender isn’t reliable. Mailgun’s white labeling service makes changes directly to your DNS records so key messages reach inboxes instead of being flagged, all while retaining your brand name. Mailgun sends on your behalf, but messages appear as if they’re being sent directly by you.

Features
Domain white labeling
Using white labeled domains, IP addresses and email links help build your reputation and convince ISPs that your marketing campaign messages should be delivered. By adding Sender Policy Framework (SPF) text to your domain record, you prevent sender address spoofing. This tells ISPs that any email from Mailgun on behalf of your domain is verified and authorized – and not likely to be spam. If you use Mailgun to send email on behalf of your own customers and partners, you can use SPF chaining to white label their domains, too.
Features
IP address white labeling
Ensure that ISPs always see your IP address as trustworthy. Use a dedicated IP address to protect your sender reputation from other, less verified senders. If you have multiple domains yourself, use the same IP address for all of them to boost sender reputation across your portfolio.
Features
Email links white labeling
Some ISPs look at message content as well as the domain when determining whether an email is spam. Because click tracking requires links to be directed through Mailgun, these can be misinterpreted by the ISP. Instead of using a link-shortening service to create URLs in your message, white label links so they appear as part of your own domain and therefore trustworthy to the ISP. The end result is more emails being delivered.

FAQ
Frequently asked questions (FAQs)
What is white label email marketing?
White labeling is a service that lets you rebrand and resell an existing email platform as your own, so all emails, dashboards, and tracking links carry your domain and branding without you having to build or maintain the infrastructure.
How does white label email marketing work?
White label email marketing allows you to send on behalf of your clients using their domains while Mailgun handles the infrastructure. Your clients authenticate their domains with SPF and DKIM and configure CNAME records so tracking and bounce handling reflect their brand.
You control the sending and performance through Mailgun, but recipients see only your domain or your client’s name and domain. This approach strengthens trust, maintains brand consistency, and keeps your role invisible.
Why choose white label email marketing for agencies?
With white label email marketing, agencies can offer branded email services without building or maintaining their own infrastructure. This eliminates the need for upfront development and reduces long-term operational costs. Clients see only the agency’s domain and interface, preserving full brand control. As demand grows, agencies can scale easily across accounts and volumes without adding technical complexity.
How do DNS records support white label email marketing?
DNS records power white‑label email marketing by ensuring your messages are authenticated and fully branded:
An SPF record specifies which mail servers can send on behalf of your domain to prevent spoofing
A DKIM record publishes a public key that allows receiving servers to verify that your messages have not been altered
CNAME records route tracking links and bounce‑handling through your own subdomains for consistent brand alignment
A DMARC record builds on SPF and DKIM by specifying how to handle unauthenticated messages and providing visibility through detailed reporting
How can I implement white label email marketing with Mailgun?
In Mailgun’s dashboard, add your custom sending domain (e.g., email.yourdomain.com) and follow the guided steps to publish SPF, DKIM, and CNAME records in your DNS. After verification, use Mailgun’s Templates to craft and send fully branded emails, then monitor deliverability metrics and logs within Mailgun to optimize performance.
