I have a lot of emails (~200k). I want to be able to access any of them even if the internet is down.
My current device runs GrapheneOS with stores like PlayStore, Obtanium and Fdroid.
My plan is: mass download the emails once, then when that is done, we sync the increments. E.g. I have 200k emails so first download all 200k. Then say tomorrow i have 5 new emails, so only syncs those instead of redownloading the full 200k.
If anyone has done this, what is your preferred app? I am trying on Fairmail right now. When select “Sync ALL messages”, it looks like it is downloading all the messages. However, this would suck if Fairmail is your only email client; because while downloading all messages, you cant even view the latest emails (notifications do come through btw)


In Thunderbird, you can download the full contents of your server-side mailbox by going to Settings > Accounts > {your mailbox name} > Fetching Mail > Local folder size > all messages, and then initiating a sync.
Just tested and it does sort of freeze that particular mailbox up while it’s downloading, which for 200k+ messages could be a while.
i’ve had gmail since 2006 and tried doing this and it took almost a week to download all of them because of this
so you always have your whole gmail database on your phone? After download all Any downsides at all like slow network?
