Reddit's post composer makes some formatting mistakes easy to miss until after you've posted — a broken link, an unintended heading, a spoiler tag that didn't parse. Drafting and previewing here first catches those before they're live. Once you're happy with the formatting, run it through the Post Removal Risk Checker against your target subreddit's actual rules.
MentionMint finds subreddits with real buyer questions your product can genuinely help answer — so you're writing for the right audience, not just any audience.
