How approval, AI and reports work on Lemmy
Approval. If the Lemmy channel belongs to a customer with approval turned on, every post waits for a yes. The client sees a preview on a review link and can approve, ask for changes or comment. A post that is changed after approval goes back for a new yes.
AI. The AI assistant can fit a post to Lemmy, keeping it under 10,000 characters, in your brand voice. It can also translate it, suggest a first comment and write alt text for pictures. Nothing changes until you accept.
Analytics. Postozo does not read post results from Lemmy, so there are no Lemmy numbers on the analytics page. You can still count clicks on your links with short links.
Bulk upload. Plan many Lemmy posts in a spreadsheet and upload them as a CSV file with bulk upload: up to 500 lines, each checked against Lemmy's rules before anything is created.
Client reports. Lemmy posts are counted in client reports, without network numbers, because Lemmy does not share them.
Client accounts. A client can connect their own Lemmy account from a client connect link, filling in Server address, Username, Password on the link page, so no password changes hands.
