Remember to pay for the subscription

I have a subscription campaign that must remind the customer to reload the card or pay the subscription amount into their account. This always on the 27th of the month then a day before the deadline which is always on the 1st of each month.
How do I enter this two deadlines when I don’t know when each Client enters the sequence? Data Timer and Delay Timer do not allow me to enter a defined date except by adding month and year but in my case I need the day.
Can you give me a suggestion?

Hi Mario, inside a Delay Timer, you can choose ‘Day of the Month’ and that will allow you to specifically choose the 27th. Everyone will then pause on that timer until the 27th.
