I have ECM NewsLetter with some links to site (another Items). When I send this Newsletter to my email by click on Dispatch button - links don't work when I click on them from the email inbox. It displays 404 not found error. But in ECM, if I click on Test button and type an email address, then go to inbox - the links works. Link - when clicked on Dispatch message button looks like: (after ec_camp there's no nulls)

And link - when clicked on Test button looks like: (after ec_camp there's a lot of nulls)
http://www.site.com/sitecore/RedirectUrlPage.aspx?ec_url=mypage.aspx&ec_camp=00000000000000000000000000000000&ec_as=00000000000000000000000000000000
Why does this happen? Only the last link works. How to generate a proper link when clicked on Dispatch message button? I appreciate any help you can provide.
I'll assume that you have separate CD + CM environments and also that you're using ECM 2.x as well.
If this is the case, we had the same issue and it's apparently a bug in ECM. When you dispatch, the campaign, message, etc are all already created, but they aren't published to the shared Web database automatically. (as one might expect) Sitecore support was able to provide us with a fix for this.
Contact support and reference issue ID 388472.
Also: The zeros are there for the campaignID and automation state when you send the test email so that it doesn't log your test against your actual campaign.
