By hand
In the admin
- When a newsletter starts to go out, PixelGlass checks its links in the background.
- If a link looks broken, a notification says how many and leads to the post's campaign page.
- Under Links, a broken one says Broken when last checked. Press Edit beside it.
- Type the New address and press Save. Every copy already sent now leads there, and the link is checked again.
- To go back to the address the post wrote, press Restore.
Editors and up fix a newsletter's links, and so does the post's own author. A link to one of your own posts follows the post when its address changes, so it needs no fix.
