Blackbaud is a US nonprofit fundraising and CRM platform serving nonprofits, foundations, and educational institutions with donor management, fundraising campaigns, and marketing automation. The unsubscribe mechanism uses the [[UnsubscribeLink]] merge tag placed in email campaigns, and Blackbaud emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the constituent record level with nonprofit-specific compliance workflows. This guide covers the tag, the constituent model, and how to verify the setup end to end.

| Tag syntax | [[UnsubscribeLink]] |
| Placement | Auto-embedded in every campaign footer |

| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Blackbaud
Place the merge tag exactly as shown below in the email template. Blackbaud replaces it at send time with a signed URL scoped to the recipient and campaign.
[[UnsubscribeLink]]For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="[[UnsubscribeLink]]">Unsubscribe from this list</a>Auto-embedded in every campaign footer
Yes, automatic for authenticated sending domains The recipient's mailbox provider (Gmail, Yahoo) uses the List-Unsubscribe-Post header to expose the native one-click button on the message. Requires domain authentication with DKIM and DMARC.
Blackbaud nonprofit-specific constituent model tracks donor relationship state alongside marketing consent. A marketing opt-out does not stop tax receipt or donation acknowledgment sends (transactional exemption). Configure appeal solicitation vs stewardship communication scoping carefully since donors may want event invitations but not fundraising appeals. Educational institution use cases require FERPA compliance overlay for student communications.
Testing your Blackbaud unsubscribe link
- Send a test message to a controlled Gmail address you own via the Blackbaud campaign preview action
- Click the footer unsubscribe link and confirm the opt-out on the landing page
- Check the subscriber or contact record: the status should be Unsubscribed within seconds
- Verify the RFC 8058 headers in Gmail: open the message, click three dots, then Show original. Look for
List-UnsubscribeandList-Unsubscribe-Post: List-Unsubscribe=One-Click

Nonprofit constituent model
Blackbaud nonprofit-specific constituent model tracks donor relationship state alongside marketing consent. A marketing opt-out does not stop tax receipt or donation acknowledgment sends (transactional exemption). Configure appeal solicitation vs stewardship communication scoping carefully since donors may want event invitations but not fundraising appeals. Educational institution use cases require FERPA compliance overlay for student communications.
RFC 8058 one-click headers
Blackbaud added RFC 8058 one-click unsubscribe automatically ahead of the Google and Yahoo February 2024 requirements. The List-Unsubscribe and List-Unsubscribe-Post headers inject on every marketing send from domains authenticated under Marketing > Email. SPF and DKIM records must be verified. Nonprofit high-volume appeals benefit from RFC 8058 to maintain inbox placement.
Fundraising campaigns and stewardship
Blackbaud fundraising campaigns and stewardship communications require careful consent scoping. Annual appeals (year-end fundraising) respect opt-out. Tax receipts and donation acknowledgments qualify for transactional exemption. Event invitations and volunteer coordination fall between: configure based on donor preference expressed at signup and give donors the option to segment communications via preference center.
