Engagement announcements

A ring, sparkles, and a teary happy face communicate the moment clearly — the ring emoji in particular is the most immediately recognizable symbol for an engagement post.

Save-the-dates and invitations

A love letter, calendar, and two hearts work well for the more formal, informational side of wedding communication, while keeping the tone warm rather than purely functional.

Wedding day posts

The bride, groom, bouquet, and wedding-building emojis cover the traditional visual elements of a wedding day, and clinking glasses fits celebratory toast-style captions.

Anniversary and long-term love posts

A red heart, revolving hearts, and a smiling face with hearts suit anniversary captions well, while heart hands has become a popular, slightly more modern alternative to a plain heart for expressing affection.
