People may send "ICYDK" in emails or messages as shorthand for "in case you didn't know" or "in case you don't know." They send it when they believe a person might not know a piece of information, such as a meeting time change or if a distant relative got married.
For example, your co-worker may email you, "ICYDK, our meeting next week with the new clients has changed to 3 instead of 1." Or, your brother may message you, "Cousin Kevin eloped last week in Mexico icydk."
People may also use ICYDK to preface a statement or possibly a hot take. For example, if someone on Twitter is a big fan of Patrick Mahomes (QB in the NFL), they might post on Twitter, "icydk, this is how you play qb" with a video of Mahomes highlights.
ICYDK is one of several acronyms people may send to notify you of something you might have missed. Some others include the common ICYMI and ICYWTBE.
