I, and others, have had issues when paying the mortgage with Evollve. If the entire payment does not arrive within the same time frame, the mortgage co will reject all payments. So I paid my mortgage partially with evolve and partially with BB for a few months, and then must have been careless with the timing one month because it all was rejected and the payments bounced back.
So now I use either: BB (bluebird), Serve, or Target RedCard for the entire payment each month.
Each of those payment methods have their own thread here on DDF. They are all prepaid Amex cards that can be funded by credit cards and you can pay bills with it on line.
