By the end of this guide, you'll understand the new Unsubscription System in lemlist, how to unsubscribe a contact from all channels or only specific contact details, where to review unsubscribe records, and what happens when unsubscribed contacts are used in campaigns.

The new Unsubscription System lets you block a contact from being reached on all channels with Do not contact, or only on specific contact details such as email addresses, phone numbers, or LinkedIn URLs.

Unsubscriptions are now managed at both:

This gives you more control and clearer traceability for every unsubscribe action.

Managing unsubscribes correctly is essential to remain a trusted and compliant outreach partner. This new system helps prevent prospects from being contacted again after they unsubscribe, even across multiple campaigns and channels.

Benefits of the new system:

You can now unsubscribe a contact in two different ways:

These unsubscriptions are reflected across contact records, campaign behavior, and team-level unsubscribe reporting.

Step 1: Open Settings

Click your profile name or avatar in the bottom-left corner, then select Settings.

Step 2: Open the Unsubscribe section and review the page

In the left sidebar, click Unsubscribe. From there, you can review all unsubscribe records and use the available search and filter tools to analyze them.

Step 3: Add variables to the unsubscribe list

Click Unsubscribe variables, then enter one value per line. You can add:

Example values:

email@example.com

@domain.com

0612345678

https://linkedin.com/in/user

Step 4: Confirm the unsubscribe

After entering the variable or variables you want to block, click Unsubscribe variables.

Step 5: Verify the new unsubscribe record

Once saved, the unsubscribed variable appears in the list with its details and timestamp.

Step 6: Select the variable and remove it

To restore a manually unsubscribed variable, select the checkbox next to it, then click Remove variables.

Step 7: Filter records by date

Use Filter by date to narrow the list to a specific time period.

Step 8: Filter records by unsubscribe type

Use Unsubscribes types... to review the source of the unsubscribe, such as:

Step 9: Filter records by variable kind

Use Filter by variable kind... to display only unsubscribed:

Step 10: Filter records by user

Use Filter by user to identify which teammate performed a manual unsubscribe action.

Step 11: Open the unsubscribe action from a contact

From the Contacts page, open the contact record, click the actions menu in the top-right corner, and select Unsubscribe. This action is also accessible from the contact panel in other places such as tasks, inbox, and the Chrome extension.

Step 12: Choose what to unsubscribe

In the Unsubscribe contact modal, choose the type of restriction you want to apply:

If a contact has multiple emails or phone numbers, you can select exactly which values to unsubscribe.

Step 13: Use Do not contact when you want to block all outreach

Select Do not contact when the contact should no longer be reached through any channel. When this option is enabled, the relevant fields are blocked for the whole contact.

Step 14: Review the result on the contact panel

After a full unsubscribe, the contact panel shows a banner confirming that the contact has been unsubscribed from all variables.

Step 15: Check the activity log for traceability

Open the Activities tab on the contact panel to see unsubscribe events and their source. This helps you track who unsubscribed the contact, when it happened, and whether it came from a user action, API, bounce, or another source.

Step 16: Understand what happens in campaigns

If a contact is unsubscribed, lemlist prevents them from being contacted in the restricted channels.

In the campaign lead list, unsubscribed contacts or values are clearly labeled.

The lead status also appears as Unsubscribed in the campaign lead table.

This system prevents prospects from being contacted again after they unsubscribe, even if they appear in multiple campaigns, channels, or records.

It helps solve common issues such as:

What’s the difference between “Do not contact” and channel-level unsubscription?

Do not contact blocks the contact from being reached on all channels across all campaigns. Channel-level unsubscription blocks only the selected channel or contact detail, while leaving the others active.

Can I unsubscribe only one email address or phone number if a contact has several?

Yes. In the Unsubscribe contact modal, you can select only the specific email address, phone number, or LinkedIn URL you want to block.

If I unsubscribe a contact from one campaign, will it affect other campaigns?

Yes. Unsubscriptions apply globally across all campaigns, not only the campaign where the action was triggered.

What happens if a contact unsubscribes during a running campaign?

All future restricted automated steps are immediately skipped across campaigns. The lead can appear with an Unsubscribed status.

How can I see who unsubscribed, when, and why?

You can review unsubscribe actions in:

Can I manage unsubscribes through the API?

Yes. Unsubscribe management is available through the API for both variable-level and contact-level unsubscriptions.
