Everlytic is a South African email and SMS marketing platform serving South African and Sub-Saharan African SMBs, mid-market, and enterprise customers with strong local deliverability, POPIA compliance defaults, and integrated SMS capabilities. The unsubscribe mechanism uses the {{unsubscribe_url}} merge tag auto-injected into every campaign footer, and Everlytic emits RFC 8058 headers automatically for authenticated sending domains. Consent is tracked at the contact level with POPIA (South African data protection law) enforcement. This guide covers the tag, the POPIA regulatory model, and how to verify the setup end to end.
Everlytic unsubscribe link
| Tag syntax | {{unsubscribe_url}} |
| Placement | Auto-embedded in every campaign footer |
| Scope | Contact-level opt-out with POPIA enforcement |
| Config path | Settings > Sender identity > Footer template |
| RFC 8058 one-click | Yes, automatic for authenticated sending domains |
How to add the unsubscribe tag in Everlytic
Place the merge tag exactly as shown below in the email template. Everlytic 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 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.
Everlytic POPIA (Protection of Personal Information Act) compliance is enforced by default, meaning imported contact lists without documented consent are quarantined until confirmed. South African senders migrating from other ESPs must provide POPIA documentation for each contact. This is stricter than US CAN-SPAM but matches South African regulatory expectations. The Information Regulator enforces POPIA with fines up to ZAR 10 million and prison sentences for repeat offenders.
Testing your Everlytic unsubscribe link
- Send a test message to a controlled Gmail address you own via the Everlytic 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

POPIA enforcement and Information Regulator
Everlytic POPIA (Protection of Personal Information Act) compliance is enforced by default, meaning imported contact lists without documented consent are quarantined until confirmed. South African senders migrating from other ESPs must provide POPIA documentation for each contact. This is stricter than US CAN-SPAM but matches South African regulatory expectations. The Information Regulator enforces POPIA with fines up to ZAR 10 million and prison sentences for repeat offenders, making platform-level enforcement essential for South African senders.
RFC 8058 one-click headers
Everlytic 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 > Sender identity. SPF and DKIM records must be verified. South African data residency defaults align with POPIA data localization preferences.
Sub-Saharan African deliverability and integrated SMS
Everlytic operates infrastructure with peering to Sub-Saharan African email networks (Vodacom, MTN, Cell C mail services) and mobile networks for SMS, giving strong regional deliverability. South African senders targeting predominantly domestic audiences see better regional inbox and SMS placement than through global ESPs. Integrated SMS capabilities let marketers coordinate email and SMS campaigns with unified consent state: an email opt-out can propagate to SMS suppression if configured, matching POPIA cross-channel consent expectations.
