ICYMI, short for "In Case You Missed It," is a popular acronym used in social media, email newsletters, and digital communications to resurface content that was shared earlier.

It helps ensure that valuable updates, announcements, or high-performing posts reach people who may have missed them in their feed or inbox.

Example:
A brand might post:

"ICYMI: We just dropped our biggest AI tools list yet – check out the 50+ platforms helping creators automate and grow. 👉"

Using ICYMI can improve content visibility, boost engagement, and extend the lifecycle of your most important posts.

It’s especially effective for repurposing evergreen content, reminding audiences about product launches, or highlighting viral moments. Many brands use it to drive traffic back to blog posts, YouTube videos, or limited-time promotions.
