when Sendy is rewriting URLs, will it first resolve custom fields within those URLs? For example, given two custom fields, such as [link] and [params], with values such as "http://example.com" and "foo=bar", should the following be expected to work?
* <href a="[link,fallback=...]?[params,fallback=...]">link</a>
That is, should we expect the rewritten Sendy URL to redirect to the following?
* http://example.com?foo=bar
Does Sendy support custom fields inside the subject line, such as "Special News for [Name]"?
