iCloud Mail rules can forward your bank alerts to Graiden as they arrive. Set them up once on iCloud.com and they run on their own.

Step 1
Open Mail rules on iCloud.com
On a computer, sign in at iCloud.com, open Mail, click the settings icon and choose Rules, then Add a Rule. Copy your Graiden address from the Graiden app first (Settings, under your forwarding address). Apple's guide

Check it works
Your next bank alert lands in Graiden on its own. To see it now, forward one old alert to your Graiden address. Avoid iCloud's Mail Forwarding setting: it sends every email, not just your alerts.
