When adding leads to instantly campaigns through the clay enrichment, it seems like not all leads are transferring to instantly despite indicating "added to campaign" in the respective column. I already checked that none of them are already in instantly.
Context: I have a list of about 2k leads who I want to allot to 10 different email campaigns in instantly. All of my leads are in one table.
QQ: what is the best practice for adding leads to different campaigns? Is it best to duplicate the table, or copy specific rows, or use filters (I've played around but havent found a clean effective way!)?
