I am testing an email we are hoping to send this morning, the links are redirecting extremely slow from the createsend URL.
For example: http://aee.createsend1.com/t/j-l-sjudyy-mluhltul-b/ does not seem to work at all. Is there an issue on your end?
I took a look at your most recent campaign draft and saw that the campaign was imported with many of our template tags in the HTML. For the campaigns which don't use templates, meaning they are imported with the content included, the template tags are not necessary and could cause many problems in the browsers/email clients when previewing.
If you can remove those template tags from the HTML, the link issues should resolve as well. Contact support if there is another campaign you were referring to, or if there is anything else we can do to help.
