As another poster pointed out, it sounds like you want more of a mail search and archival tool than a mail server. I would suggest you pull the emails in maildir format from Google Takeout, and then index/search them with the amazing Notmuch. Notmuch is way more capable than Gmail search ever has been. Look at the Arch Wiki page page as well for info, the official docs are a bit obtuse but it’s not actually hard to use.

Not sure if it tracks like your actual portfolio breakdown, it might have access to that info but for Actual Budget it just shows the balance on the account.

Has worked really well for me. Like I mentioned I’ve had a couple instances where the banks change their login flow and I had to open a support ticket to get it fixed, but they (SimpleFIN) were very responsive in working on it when I opened a support request and had it fixed within a couple days. Two of my accounts also have to be re-authenticated every time I wanna pull data into Actual, but that’s also the banks’ fault and it’s not that big of a deal to do.

As for integration with Actual is basically flawless and just works. Setup is super easy, just paste in a token from SimpleFIN and boom you see all the accounts you have linked and can attach them to accounts in Actual. Sync is rock solid too, I don’t have any issues with it messing up transactions with duplicates etc.

It varies by bank but for all mine you have to use the username and password unfortunately. My understanding is that it’s just how the underlying bank APIs work in general, because that’s what I have to do when I link accounts for my banks elsewhere too, not just in SimpleFIN. I don’t think they actually store your credentials though, I think it proxies it to the bank login and then caches a token. You can probably ask their support about the details if you’re concerned, they have been pretty responsive to me and willing to answer technical questions.

It does support investment accounts, I have my retirement and investment accounts in there. It supports just about every account I have, actually, credit cards included which is super handy. I think it’s all read-only access through, so you can only use it to import data not make new transactions.

In the US it has integration with SimpleFIN. SimpleFIN isn’t free but it’s pretty cheap ($1.50/mo) and supports most banks out there, even my obscure local credit union. It works pretty well, though sometimes the banks fuck with stuff and seem hell bent on breaking any kind of API access, but SimpleFIN support was really responsive for me to get it fixed when it happened. I do also have to reauthenticate my bank every day when I want to sync, but that’s also just the banks being assholes and isn’t too bad to do.
