Can I send cards like Valentines cards or birthday cards to.my inmate?

The short answer is "yes", but there is a little more to it. One of the reasons InmateAid offers the Greeting Cards service is that the process follows strict guidelines for incoming mail. Most store-bought cards have glitter or other affixings that might cause it to be rejected in the mail room of the prison. The selection of cards on InmateAid are delivered on a postcard that meets the standards of every facility in the US. For 99 cents each, it doesnt make sense to take a chance that it's gets rejected.
