Rollup
Your newsletters, rolled up into one readable weekly briefing.
Newsletters I asked for still bury the inbox. I want them, just not every morning, and not as fifty separate messages.
Rollup takes the newsletters sitting in Thunderbird and turns them into one weekly briefing I can actually read. It only reads; it does not send.
The briefing comes out as a page I can keep. If I want a shorter pass, it can summarise on this machine. Nothing is uploaded.
I use it as a weekly habit. I am still shaping the digest so it reads like something I would sit down with, not a dump of subject lines.
