How much data is being sent per issue? If I divide “message size a client should handle” by 473, I get a really big number.
It’s actually double that amount because i’m sending html and plaintext emails so the data is duplicated.
A message with 22 issues is about 36 KB on disk.
So (36 kb/ 22 ) => 1.6 KB per issue (not perfect but approximate)
1.6 KB * 473 => 756 KB, which actually doesn’t sound like a system crashing email. Maybe it’s not the size but rather the layout engine trying to render all the text or something. ¯\_ (ツ )_/¯
