Spotler Mail (from the CommuniGator acquisition line) is another Spotler group product serving UK B2B mid-market with marketing automation, lead scoring, and CRM integration. The unsubscribe mechanism uses the {UnsubscribeLink} merge tag auto-injected into every campaign footer, and Spotler Mail emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with UK PECR enforcement and Salesforce/Dynamics/HubSpot CRM bidirectional sync. This guide covers the tag, the CommuniGator lineage, and how to verify the setup end to end.

Watch out for this

Spotler Mail (from CommuniGator acquisition) uses a different tag syntax than Spotler SendPro, Pure360, or Mail+ (formerly Webpower). Customers migrating between Spotler products must convert templates. CRM bidirectional sync with Salesforce, Dynamics, and HubSpot means CRM-side opt-outs suppress Spotler Mail sends and vice versa, essential for B2B unified consent state.

Testing your Spotler Mail+ unsubscribe link

  1. Send a test message to a controlled Gmail address you own via the Spotler Mail+ campaign preview action
  2. Click the footer unsubscribe link and confirm the opt-out on the landing page
  3. Check the subscriber or contact record: the status should be Unsubscribed within seconds
  4. Verify the RFC 8058 headers in Gmail: open the message, click three dots, then Show original. Look for List-Unsubscribe and List-Unsubscribe-Post: List-Unsubscribe=One-Click

Spotler Mail default templates include the unsubscribe link in the footer, but custom HTML templates require the tag inserted manually.

  1. Open your campaign or template in the Spotler Mail editor.
  2. Add or edit a text block in the footer where the unsubscribe link should appear.
  3. Insert the merge tag {UnsubscribeLink}. Spotler Mail replaces it at send time with a signed URL scoped to the contact.
  4. Wrap it in an anchor: <a href="{UnsubscribeLink}">Unsubscribe</a>.
  5. Configure the sending domain under Settings > Templates > Footer configuration.
  6. Send a test to a seed address and verify the rendered link routes to the Spotler-hosted preference page.

CommuniGator lineage and Spotler product family

Spotler Mail (from CommuniGator acquisition) uses a different tag syntax than Spotler SendPro, Pure360, or Mail+ (formerly Webpower). Customers migrating between Spotler products must convert templates. CommuniGator was a UK-founded B2B marketing automation platform acquired by Spotler group, with strong lead scoring and Salesforce CRM integration. Legacy CommuniGator accounts continue functioning under the Spotler Mail branding with backward compatibility for existing templates.

RFC 8058 one-click headers

Spotler Mail 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 Settings > Templates > Footer configuration. SPF and DKIM records must be verified. UK data residency defaults align with UK PECR and GDPR expectations for British B2B brands.

Spotler Mail CRM bidirectional sync with Salesforce, Microsoft Dynamics, and HubSpot means CRM-side opt-outs suppress Spotler Mail sends and vice versa, essential for B2B unified consent state. Configure the sync direction and field mapping carefully: a bidirectional sync means an opt-out anywhere in the tech stack propagates everywhere, which is usually the desired B2B behavior. Missing this sync creates situations where a prospect who unsubscribes from Spotler Mail still receives outreach from a manual CRM-triggered email.
