This error commonly occurs when you have created or selected a keyword that matches the exact name of your shop. Postscript is unable to differentiate between the two and so it displays the error.
In the example below, you'll see the shop name and keyword are both PSROOTS. When we edit the message so that the two are not identical, we're able to generate our opt-in link.
