yep, excellent use case! I did something similar with my gmail recently, because I hate using gmail's UI and I also hate that I don't get access to all my data, but I've begun to regularly backup all my email into a local postgres DB (including attachments). AI has also allowed me to get a full backup of my entire email and archive it onto my own storage. and the best part of this: I might be able to finally get off gmail

good question. maintenance is cheap with tools like astra/opus. also, these aren't production level applications, so I don't need to worry about it being "perfect" (though there's no such thing)
