This product was not featured by Product Hunt yet. It will not be visible on their landing page and won't be ranked (cannot win product of the day regardless of upvotes).
MailVault connects to your email accounts via IMAP and downloads everything to your computer as standardeml files — a format you can open anywhere, forever. Running out of storage? Archive old emails locally and free up space without losing anything. Shutting down a hosting plan or switching providers? Save everything before it's gone. Works with Gmail, Outlook, Yahoo, and any IMAP provider. OAuth2 login, threaded conversations, full search, attachments included. Your emails, your hardware.
I built MailVault because of my friend Tomas. Tomas works in logistics. Every few months he hits the same wall — his 10GB mailbox is full. Again. His inbox is packed with CMR documents, invoices, shipping confirmations, and customer correspondence — all with heavy attachments. He can't just delete them. Regulations require him to keep these records, and he needs them to resolve disputes with customers.
So every time his mailbox fills up, he's stuck: pay for more server storage, manually export emails to folders on his desktop, or risk losing documents he's legally required to keep.
That's the moment I realized — there's no simple tool that just downloads your emails to your computer and lets you free up server space without losing anything.
Everything I found was either a full email client I didn't need, enterprise backup software that cost hundreds, or some sketchy tool that hadn't been updated since 2015.
So I built what I wanted — connect your account, download your emails as .eml files, done. Standard format, works offline, no cloud, no subscription.
The biggest technical challenge was making it work reliably across providers. Gmail, Outlook — they all have their quirks. Microsoft even broke IMAP OAuth for personal accounts late 2024 and still hasn't fixed it, so I had to build a whole separate Microsoft Graph API transport as a workaround.
MailVault is completely free — and open source. You can see exactly what happens with your credentials and data. No hidden costs, no tricks. I want to get it into as many hands as possible and build something people genuinely need.
