Many of us these days have multiple accounts, some we use everyday, others less frequently.
With the Marygold app you can link as many external current accounts as you like, and then create as many low-balance alerts as you wish.
So whether you need an alert for an infrequently used current account if the balance drops below £100, or multiple alerts set at £500, £300 and £100 for a frequently used account, it is totally up to you.
Being forewarned of possible overdrafts far enough in advance lets you adjust your spending or allocate funds appropriately, so you don't get stung with high overdraft fees or failed payments.
