AWeber is one of the oldest email marketing platforms in the industry, still popular with creators, bloggers, and small businesses that value simple broadcast tools and a mature autoresponder library. The unsubscribe mechanism uses the dot-notation subscriber attribute merge tag, auto-injected into every default broadcast footer, and backed by a single account-wide subscriber status. AWeber emits RFC 8058 one-click headers automatically for every marketing send once the sending domain is authenticated. This guide covers the tag, the footer setup path, and the one gotcha to watch for when using a custom HTML template.
AWeber unsubscribe link
| Tag syntax | {!unsubscribe} |
| Placement | Auto-embedded in every broadcast footer |
| Scope | Account-wide subscriber status |
| Config path | Messages > Global Text Snippets > Footer |
| RFC 8058 one-click | Yes, automatic for all broadcasts |
How to add the unsubscribe tag in AWeber
Place the merge tag exactly as shown below in the email template. AWeber 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 broadcast footer
Yes, automatic for all broadcasts 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.
Custom HTML templates that override the default footer must include the merge tag manually. AWeber blocks the broadcast from sending if the tag is missing, but the error message only appears at the final confirmation step, not in the visual editor. Test with the preview send before scheduling a large campaign.
Testing your AWeber unsubscribe link
- Send a test message to a controlled Gmail address you own via the AWeber 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 AWeber handles the unsubscribe link
AWeber injects the unsubscribe link into every campaign through a system-managed footer variable that cannot be removed. The variable is rendered as {!remove_web} in the raw HTML for legacy templates and as an automatic footer block in the modern drag-and-drop editor. When a subscriber clicks the link, AWeber records the opt-out and moves the contact to the Unsubscribed status, which prevents any future campaigns from being delivered to that address across the entire account.
Customizing footer appearance
The footer text around the unsubscribe link is customizable through Account Settings, letting brands adjust styling, wording, and physical address format. The link itself is always managed by AWeber and cannot be redirected to an external system. This is a deliberate design choice: allowing custom endpoints would break the account-wide suppression model and expose the sender to compliance risk. For senders that need a custom preference center, AWeber offers a hosted preference feature that lets users switch between different lists rather than opt out entirely.
Suppression and re-subscription
Once a subscriber unsubscribes, AWeber marks them as Unsubscribed globally. Attempting to re-add the same address through CSV import or manual entry fails silently to protect senders from CAN-SPAM violations. The only way to re-add an unsubscribed contact is through a fresh subscription confirmation initiated by the subscriber themselves via a signup form or landing page. This is stricter than some competitors that allow forced re-adds with acknowledgment.
RFC 8058 and 2026 deliverability
AWeber implements RFC 8058 one-click unsubscribe headers on all sending domains that have completed DKIM authentication in the platform. The List-Unsubscribe and List-Unsubscribe-Post headers are added automatically. Since AWeber has been in operation since 1998 and has decades of deliverability tooling, most accounts satisfy the Google and Yahoo requirements without customer intervention. Newer accounts should complete the Custom Sending Domain setup for full one-click headers.
