To ensure proper email branding and deliverability, all Opensense customers must configure specific DNS records. These updates should be applied to both external and, if applicable, internal DNS environments.

Note: These changes are typically handled by your IT administrator or DNS host provider.

Why This Is Important

  • Consistent brand presentation across emails.

  • Improved email deliverability and authentication alignment.

  • Support for Opensense's email signature and tracking infrastructure.

DNS Records Required by Opensense

1. CNAME Record (New Entry)

Record Type

Host/Name

Points To / Value

CNAME

smart

whs.sendergen.com

Instructions:

  • Create a new CNAME record where:

    • smart is the subdomain/host.

    • whs.sendergen.com is the target domain.

2. SPF Record (Modify Existing TXT Record)

Record Type

Host/Name

Value (Example)

TXT (SPF)

@ or your domain root (e.g. customer.com)

v=spf1 include:_spf.google.com include:_spf.sendergen.com ~all

Instructions:

  • Locate your current SPF TXT record (typically begins with v=spf1).

  • Add the following include statement to the existing entry:

  • include:_spf.sendergen.com

  • Do not create a separate SPF record. There must only be one SPF TXT record per domain.

  • The underscore in _spf.sendergen.com is critical—ensure it is not omitted.
