Inbox (useinbox) is a Turkish email marketing platform popular with SMBs and e-commerce operators in Turkey, Central Asia, and MENA markets, with strong multi-currency and multi-language support. The unsubscribe mechanism uses the {unsubscribe} merge tag auto-injected into every campaign footer, and Inbox emits RFC 8058 headers automatically once the sending domain is authenticated. Consent is tracked at the list level with a preference center option available. This guide covers the tag, the multilingual footer configuration, and the regional deliverability considerations.

How to add the unsubscribe tag in useinbox
Place the merge tag exactly as shown below in the email template. useinbox replaces it at send time with a signed URL scoped to the recipient and campaign.
{unsubscribe}For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:
<a href="{unsubscribe}">Unsubscribe from this list</a>Auto-embedded in every campaign footer
Yes, automatic once sending domain is authenticated 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.
Inbox multilingual accounts (Turkish, Arabic, English, Russian) need a language-locale-specific footer variant, or the auto-generated unsubscribe link renders in the account default language regardless of recipient language. Set the language preference on the contact record to route the correct footer variant. This is particularly important for cross-regional MENA campaigns.
Testing your useinbox unsubscribe link
- Send a test message to a controlled Gmail address you own via the useinbox 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

How to add the Inbox unsubscribe link (step by step)
Inbox drag-and-drop templates include the unsubscribe link in the default footer, but custom HTML templates require the tag inserted manually.
- Open your campaign or template in the Inbox editor.
- Add or edit a text block in the footer where the unsubscribe link should appear.
- Insert the merge tag
{unsubscribe}. Inbox replaces it at send time with a signed URL unique per subscriber. - Wrap it in an anchor with your preferred label:
<a href="{unsubscribe}">Aboneliği İptal Et</a>for Turkish audiences. - Add the physical postal address block. Inbox reads it from Settings > Sender identity.
- Send a test to a seed address and verify the rendered link routes to the Inbox-hosted preference page.
Multilingual accounts and language routing
Inbox multilingual accounts (Turkish, Arabic, English, Russian) need a language-locale-specific footer variant, or the auto-generated unsubscribe link renders in the account default language regardless of recipient language. Set the language preference on the contact record to route the correct footer variant. This is particularly important for cross-regional MENA campaigns where a Turkish sender reaches Arabic-speaking recipients in Egypt or UAE. The preference center inherits the contact language attribute for consistent multilingual UX.
RFC 8058 one-click headers
Inbox 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 > Sending domains. SPF and DKIM records must be verified. Since Inbox serves emerging market senders where domain authentication practices vary, the platform provides an automated DNS-check wizard to help account admins configure the required records correctly.
Turkey and MENA regional deliverability
Inbox routes sends through Turkey-based infrastructure with peering to European and Middle Eastern email networks. Recipients in Gulf countries (UAE, Saudi Arabia, Kuwait) may see slightly higher inbox latency compared to sends from European ESPs due to routing paths. For senders targeting predominantly Gulf recipients, monitor delivery-to-open latency and consider Inbox regional POPs (available on higher tiers) to reduce inbox delivery time. Complaint feedback from Turkish and Arabic-speaking recipients is processed in real-time and syncs to the account-wide suppression list.
Frequently Asked Questions
What is the Inbox unsubscribe tag?
The tag is {unsubscribe}. Inbox replaces it at send time with a signed URL unique per subscriber. Use it inside an anchor: <a href="{unsubscribe}">Unsubscribe</a>.
Does the Inbox footer localize automatically?
Yes when the contact has a language preference set. Inbox reads the contact language attribute to route the correct footer variant. Cross-regional MENA senders should set the language attribute during import to route Turkish, Arabic, English, or Russian footers accurately.
Does Inbox support one-click unsubscribe for Gmail and Yahoo?
Yes, automatically for authenticated domains. Inbox injects List-Unsubscribe and List-Unsubscribe-Post headers on every marketing send from domains verified under Settings > Sending domains. Use the DNS-check wizard to validate SPF and DKIM configuration.
Are there regional POPs for Gulf recipients?
Yes on higher tiers. Regional POPs reduce inbox delivery latency for Gulf and MENA recipients. Contact Inbox account manager to enable POPs based on your primary recipient regions.
Can I resubscribe a contact who unsubscribed from Inbox?
Not through the API. Inbox enforces permanent suppression on opt-outs. The contact must re-opt in through an Inbox signup form or preference center action, which resets the subscription state.
