ICYMI.
ICYMI stands for “in case you missed it,” used to flag a repost or reminder of something previously shared.
What does ICYMI mean?
A brief tag added before a link, video, or statement to signal that the content has been posted before and may have been overlooked by some readers.
Functions as a courteous nudge, letting the audience know the material is worth revisiting without implying they were inattentive.

Still wondering?
Can ICYMI be used for a brand‑new post?
No. ICYMI signals that the material has already appeared elsewhere; for new content, simply share without the tag.
Is ICYMI appropriate in professional emails?
It is informal, so reserve it for casual internal communications or social‑media posts rather than formal business correspondence.
