Steal the skeleton
Subject that names a loss or a job. Two short paragraphs. One link. P.S. with the same link. That is the useful part of the pack. The rest is period flavor. Delete it.
Write the subject last
After the body is honest, pull five words from the first sentence. Subjects that shout FREE tend to train filters and readers to ignore you.
Send a test to yourself on a phone
If the link wraps badly or the first line is cut off, fix that before anyone else sees it. Templates are a start. The send is yours.
