I got confirmations that my mortgage payments were sent today. One thing to remember about this service, it's not only the time it takes for the payment to arrive, but also the time it takes the payee to process the paper check. This can range from same day to many days depending on the payee.
I now send all of my Plastiq payments 2 weeks before the due date. That way, if there are any issues, I can always make an electronic payment to avoid late fees if necessary. Then if the Plastiq payment does end up going thru, that is just next month's payment early.
I really hope they beef up the list of companies they can use ACH with. That would really make them better than Evolve.
