Change the email on your bank accounts and let the agent fill in the forms
The poster wanted a new email address on their bank accounts, so they asked their Gemini Spark agent to write and send the request. The bank replied with a form to fill in. Spark pulled the details from the poster's Google Drive and filled in two forms, one for each account, so all that was left was to sign and send them.

I want to change the email address on my accounts at [BANK] from [OLD EMAIL] to [NEW EMAIL]. Write a short request to their support address [ADDRESS] and show it to me before you send it. If they reply with a form, fill it in using my details from the files in my Drive folder [FOLDER NAME], one form per account, and leave the signature for me.
