Montly spending report
It would be awesome to have a monthly report on your spendings from various bank accounts. So on the first of the month you get an email with all your expenses (and possibly locations, maybe even certain milestones). Are you familiar with the Google Maps Timeline update?
I can help with the styling of the email, but want to ask you first what the best way to implement this would be. If you're in favor of this idea as well!
The 'IFTTT way' to do this, is to write a trigger that produces the monthly report and then use the email function to send it. This means you have to do the timing yourself (as it is not possible to chain two actions, e.g. data/time trigger -> produce report -> mail it)
That said, I think this is a bit too specific to include in bunq2IFTTT...
btw: in the future a better way within IFTTT would be to use their queries functionality, but this is still under development at IFTTT
