Ex files

Wanda and Ken Bass created XCards to help divorced couples remain connected.

Greeting cards still help consumers stay in touch — even former spouses.

XCards, a greeting card line that caters to divorced parents, aims to use the power of the written word to help exes remain friendly for the sake of their children.

“Co-parenting may not require friendship right away, but it does require cooperation in order for your children to grow up in a socially healthy environment,” XCards co-founder Wanda Bass told the Huffington Post recently.

Bass and her ex-husband, Ken, got the idea for business after they divorced in 2002.

One of their Father’s Day cards begins, “When I look back, I don’t regret you being the father of our children.” A birthday card notes that “we don’t celebrate things together the way we used to,” then adds, “I want your day to be extra special the whole day through.”

Bass said her sons with Ken “are just as excited as we are about the positive impact Xcards can have on families.”

Although First-Class Mail has declined in recent years, greeting cards remain popular with consumers, a recent study found.
