XtremePush is an Irish multi-channel customer engagement platform serving mid-market and enterprise B2C brands (iGaming, retail, financial services) with push notifications, email, SMS, in-app messaging, and Web Push from a unified user model. The email unsubscribe mechanism uses the {{unsubscribe_url}} Liquid tag in email templates, and XtremePush emits RFC 8058 headers automatically for authenticated domains. Consent is tracked per channel by default with cross-channel enforcement available. This guide covers the tag, the multi-channel model, and how to verify the setup end to end.

How to add the unsubscribe tag in xtremepush
Place the merge tag exactly as shown below in the email template. xtremepush replaces it at send time with a signed URL scoped to the recipient and campaign.
{{unsubscribe_url}}For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="{{unsubscribe_url}}">Unsubscribe from this list</a>Auto-embedded in default email footer
Yes, automatic for authenticated sender 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.
XtremePush is popular in the iGaming vertical which has strict regulatory requirements around unsubscribe handling and consent capture. iGaming operators must configure the Regulatory Compliance module to enforce jurisdiction-specific opt-out defaults (UK, Malta, Sweden all have different requirements). Missing this configuration causes compliance violations on cross-border sends to regulated markets.

How to add the XtremePush unsubscribe link (step by step)
XtremePush email templates include the unsubscribe link in the default footer, but custom HTML templates and campaign-specific templates may require the tag inserted manually.
- Open your email campaign or template in the XtremePush dashboard.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the Liquid tag
{{unsubscribe_url}}. XtremePush replaces it at send time with a signed URL scoped to the user record. - Wrap it in an anchor:
<a href="{{unsubscribe_url}}">Unsubscribe</a>. - Configure the sending domain under Settings > Channels > Email > Sender configuration. SPF and DKIM must be verified.
- Send a test to a seed address and verify the rendered link routes to the XtremePush-hosted preference page.
Per-channel opt-out and unified user model
XtremePush unifies user profiles across channels (push, email, SMS, in-app, Web Push) but tracks opt-out per channel independently by default. A user unsubscribing from email marketing keeps receiving promotional push and SMS unless cross-channel enforcement is enabled at the org level. Consumer brands typically enable cross-channel to respect blanket opt-outs; B2B senders and iGaming operators often keep per-channel control since a user may want transactional push (deposit confirmation) but not marketing emails.
RFC 8058 one-click headers
XtremePush 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 email send from domains authenticated under Settings > Channels > Email > Sender configuration. SPF and DKIM records must be verified. Push, SMS, and Web Push channels are exempt from RFC 8058 which targets email specifically.
iGaming compliance and regulatory jurisdictions
XtremePush is popular in the iGaming vertical which has strict regulatory requirements around unsubscribe handling and consent capture. iGaming operators must configure the Regulatory Compliance module to enforce jurisdiction-specific opt-out defaults (UK Gambling Commission, Malta Gaming Authority, Sweden Spelinspektionen all have different requirements). Missing this configuration causes compliance violations on cross-border sends to regulated markets, exposing operators to license risks and fines. Non-iGaming brands can skip this module.
Frequently Asked Questions
What is the XtremePush email unsubscribe tag?
The tag is {{unsubscribe_url}}. XtremePush replaces it at send time with a signed URL scoped to the user record. Use it inside an anchor: <a href="{{unsubscribe_url}}">Unsubscribe</a>.
Does an email unsubscribe stop push and SMS on XtremePush?
No by default. Email unsubscribe applies only to the email channel, preserving push, SMS, in-app, and Web Push subscriptions. Enable cross-channel enforcement at the org level to make one unsubscribe click apply across every channel simultaneously.
Does XtremePush support one-click unsubscribe for Gmail and Yahoo?
Yes, automatically for authenticated domains. XtremePush injects List-Unsubscribe and List-Unsubscribe-Post headers on every marketing email send from domains verified under Settings > Channels > Email > Sender configuration.
How does XtremePush handle iGaming regulatory unsubscribe requirements?
Via the Regulatory Compliance module which enforces jurisdiction-specific opt-out defaults for UK, Malta, Sweden, and other iGaming markets. Configure the module per licensing jurisdiction to meet regulator expectations. Non-iGaming brands can skip this module.
Can I customize the XtremePush preference center?
Yes. The preference center supports enterprise branding (logo, colors, brand identity) and per-channel opt-out toggles. Enterprise accounts can host the preference page under a custom subdomain via CNAME configuration.
