Congratulations Cards for Engagement ...? - saying for an engagement card

We send our offer of dedication and most of them have received calls from our friends / family. We were thanked for their "Congratulations". However, only a greeting card to get with us in our commitment to our neighbors. More if / when we are grateful, it's something I should do?
It was not a gift, but only the card. I'm not doing something wrong.
