Frequently Asked Questions
Everything you need to know before setting up automation.
Is it safe to let LetFinflow read my emails?
Yes, it is 100% safe because we do NOT 'log in' to your email account. Instead, you set up a rule to forward ONLY specific bank emails to your unique LetFinflow receiving address. You have full control over what we see.
Which bank emails can I use this with?
The system can currently read data from email notifications from KBank, SCB (Siam Commercial Bank), Bangkok Bank (BBL), Krungthai (KTB), Krungsri (BAY), and TMBThanachart (TTB). Our AI is continuously learning new formats.
What if the AI misreads a merchant or category?
All auto-synced transactions can be easily edited in the app. You can correct the merchant, amount, or category at any time. Every time you make an edit, our AI learns your preferences for next time.
Does this only work with Gmail? Can I use a corporate email?
It works with **ANY email provider globally!** Whether you use Gmail, Outlook, Hotmail, Yahoo, or a custom corporate domain, as long as your email provider allows you to set up automatic forwarding rules, you can use this feature.
Does Auto-Sync consume my credit quota?
Yes — processing 1 email alert uses 1 credit. The Free plan starts with 10 credits/month, and the Pro plan includes up to 500 credits/month. If you run out, syncing pauses until the next billing cycle.
