Verdict

Missinglettr does one unusual thing: point it at a blog post and it generates a year-long drip campaign of social posts, complete with pulled quotes, hashtags, and images, then publishes them on a schedule. It's a content-repurposing tool for bloggers more than a general scheduler.

Most schedulers ask you to bring the posts; Missinglettr writes them for you from content you already have. Connect a blog, and for each new post it builds a campaign of around a dozen social posts, drip-fed over the following year, each pre-filled with a quote, hashtags, and an image you can approve or tweak. For a blogger or content marketer who wants to keep squeezing value out of evergreen articles without writing fresh social copy every week, that's genuinely useful, and the curate community adds a steady supply of others' content to share. The flip side is that it's narrow. It publishes to six networks, has no comment inbox, no real listening, and isn't built to be your day-to-day posting and engagement hub. There's a free plan and Solo is cheap at $9 a month on annual billing, so it's easy to try alongside a main tool. Treat Missinglettr as a repurposing engine bolted onto your content, not a replacement for a full social media manager.
