Why this matters
Links carry reputation signals separate from the sender domain. Unknown tracking domains, long redirect chains, and public shorteners make filtering decisions harder to debug.
If only one campaign template has poor placement, link behavior is one of the first content checks to review.
How to fix it
Use a branded tracking domain that matches your sender identity where possible. Avoid public shorteners and unnecessary redirect hops.
Keep links readable, remove unused links, and rerun a comparable test with the same sender and seed segment.
