My bank connection dropped recently and I was only notified about this in the app. I don’t open the app frequently and people who are just using the autosavings feature may like to not open the app for a while and be pleasantly surprised about the amount they have saved.
Is there currently an email notification of the bank connection dropping? I don’t think I am opted in to marketing so if it is classed as a marketing email (I don’t think it should be but…) then that may be why I didn’t get an email notification.
If there is not currently an email notification, I think it would be worth emailing people 7 days before their bank connection drops. You could also possibly send a text message.
This could all be optional as part of a settings screen in the app since some people may not want to be contacted outside of the app.
Just my thoughts,
