Meta, Google, TikTok, Klaviyo and Shopify change something every week. AdShift logs each one with the date, the source, how much it matters, and what to do about it.
Free. One email every Monday with the changes that matter and the deadlines coming up.

What to do: Find any live poll ads and plan replacement creative. Ask tool vendors to strip poll fields from creative specs before Oct 27.
