Second step is fill in your personal information and other information, agree to the terms and conditions and voila! Your account is opened!The third step is to link an external checking account, like your Wells Fargo checking account for example. This is one of the ways you would feed money into your brand new HYSA! American Express would then send two test transfers and after you confirm, your accounts will be linked.That's basically it! Super easy, right?If you want to put more money into your new HYSA automatically, you can also set up an automatic transfer from your linked external account every month into your new HYSA. Or you can set up a portion of your paycheck to be directly deposited into your new HYSA.I hope this will convince you to open a HYSA today and start accruing interest.
