Make your complex DNS Simple

Deliver Better

DNS for Email Best Practices

SproutDNS helps you comply with email authentication and alignment best practices - including the requirements recently announced by Google and Yahoo - by providing set-and-forget dynamically templated DNS for customer-specific domains.

Fully authenticated: All your customers, even those without their own domain, can have fully aligned SPF and DKIM email authentication and DMARC.
Fully aligned: Authentication, image links and click-tracking links can all align with the customer domain or subdomain.
Isolated reputation: As every customer uses their own domain or subdomain, not shared with any other customer, their reputation and deliverability will not be impacted by the behaviour of other customers.
Self-hosted: SproutDNS runs as a standalone docker image, running on your own hosting without any third-party infrastructure.

Templated DNS

Flexible DNS for Email Providers

If you need to have customer-specific DNS generated automatically for thousands of customers and want it to just work as you onboard new customers you may have wished for DNS that works like this:

selector._domainkey.customer.example.com. CNAME \
selector.dkim.example.com.

Or like this:

_dmarc.customer.example.com. TXT \
"v=DMARC1 p=none rua=rua+customer@example.com"

... for any value of selector or customer that's asked for.

SproutDNS can do all that by matching regular expressions in DNS queries and synthesizing answers using those values.

It's like DNS wildcards turned up to eleven.
