We can create DKIM signatures for the following solutions:


  • Blackbaud NetCommunity
  • Blackbaud Internet Solutions
  • Blackbaud Merchant Services*
  • Online Express
  • Altru
  • Luminate Online / LO Beta
  • RE NXT Email
  • eTapestry (Advanced Mass Email)**

*Blackbaud Merchant Services includes MobilePay feature
**DKIM signatures for eTapestry can only be created for Advanced Mass Messages. eTapestry Basic Email Messages are not currently compatible with DKIM.

In some email clients, your NetCommunity, Internet Solutions, Online Express or Altru emails may appear with an additional line after the sending domain, which reads: "Via [NetCommunity domain]" or "Via [siteid].bbnc.bbcust. com".  A DKIM signature will prevent this from happening.

When you're ready to implement DKIM, please chat with support and reference this article. You'll need to know:
  • Domain name for the email to be signed as "from" i.e. blackbaud.com
  • Site ID
After Support enables DKIM for your organization, they’ll send you a file with a .pub extension (which is not a Microsoft Publisher file) to publish through your DNS provider, such as GoDaddy, Network Solutions, or Active Domain. After you publish it, it can take up to 48 hours for DNS changes to propagate through the entire internet. 

Blackbaud doesn't provide support for publishing the file. If you need assistance please work directly with your DNS provider.
