Common phrases on wedding cards include: "Best wishes," "Congratulations to you both on finding the perfect person to share all your days with," and "Feeling so much joy as you join your lives in marriage!" Phrases should be supportive, personal and offer blessing over the marriage.
Common phrases in wedding cards should express gratitude for the opportunity to share in the couple's wedding day. Phrases that accomplish this are, "We're thrilled to celebrate your wedding with you," and, "It is such an honor to be among those to witness your vows and wish you a lifetime of happiness." Wedding cards that express thanks to the couple are appropriate when the sender doesn't know the couple well or has complicated feelings about the marriage.
When the sender is unable to attend the wedding, common phrases for cards are, "I am with you in spirit as you join hearts and lives forever," and, "As you lift your glasses to each other tonight, I lift mine to you both from afar. Here’s to a truly amazing couple and to a marriage filled with every happiness."
If one of the newlyweds is a family member, a common phrase to introduce the new spouse to the family is, "Today, our family grows by one new member in love and happiness."
