Your problem
Can anyone help - I have just been checking with Litmus on inbox deliverability and I’m getting a message saying that there is an issue with some systems (outlook) being the main one. They are saying that have an issue with my List-Unsubscribe header. does anyone have any ideas on how I can fix this?
The message I got was:
We have detected your message does include a List-Unsubscribe header, however it only provides the URL https://automate.marketingai.co.uk/email/unsubscribe/5fa976585f3a6301974016 and does not include the mailto: function. Litmus recommends including a valid and monitored email address option when implementing the List-Unsubscribe header in marketing messaging.
Welcome to the Mautic Forums. I think they mean you need an unsubscribe link in your email.
You can add {unsubscribe_url} in your email as a link.
Some of the Tokens Available in the Email builder:
Unsubscribe Text: {unsubscribe_text}
Unsubscribe URL: {unsubscribe_url}
Web View Text: {webview_text}
Web View URL: {webview_url}
thanks for the response, No its the email header where I’m having the issue. I do have the unsubscribe in the body as you say but Litmus is claiming there is an issue in the email header that I should resolve.
instead of adding on each email can I add it to the custom email headers in the config so that it appears on every email automatically?
i get everything apart from the http://www.example.com/unsubscribe.html bit. how do I create the URL? this is dynamic right? (it will be different for each user)
Global custom email headers can also be setup in your config. Click the Gear icon => Configuration => Mail & Send Settings
The unsubscribe URL would be the same link that is rendered from the short-code inside your email as I referenced above. You’ll have to check what renders in your emails if you put this link. I’ve not tested if this short-code will render in the custom headers section. If you configure custom unsubscribe forms for each email you may need to set-up the header per email.
Hello @harry5,
Thx for bringing up this important topic.
The email is added if you have a monitored mailbox. There was a bug related to this, you can see there how this email looks like:
If you want to know more about monitored mailbox, you can find it here:
At the risk of replying to a thread that isn’t active anymore, I tried following the suggestion here to add a List-Unsubscribe header to all emails via Email Sending configuration. However, this doesn’t seem like a valid solution because the headers in these configurations aren’t applied to Mautic emails (see the tooltip):
I don’t want to add the List-unsubscribe header to all emails manually because our emails are created and sent via the REST API. I also saw that the REST API doesn’t provide the capability for adding custom headers to emails created through it.
