What it does
Missinglettr detects published content and prepares social campaigns that distribute it over time. A shared calendar, campaign approvals and analytics help publishers promote an existing article library. Paid workspace plans have a card-free trial.
Missinglettr is built around the article after publication. It detects new content, adds it to a library and prepares a social drip campaign to promote it over time. A publisher can give older useful articles another planned run as well as promoting new work.
After registering and confirming your email, set up a workspace with the brand name, logo, colour and publishing time zone. Connect the social destinations, then open Content Sources and choose Add content source. Supply a blog or supported video-source URL so Missinglettr knows where to find the material.
New campaigns wait for review and approval before posting. For a detailed guide, edit the messages to describe distinct sections or takeaways instead of repeating the headline. Their dates then appear alongside the other campaigns in the shared calendar.
| Plan | Social profiles | Workspaces and collaboration |
|---|---|---|
| Solo | 3 | 1 workspace and 1 extra user |
| Pro | 10 | 3 workspaces |
| Agency | 25 initially | Unlimited workspaces and users; branded client interface |
| Enterprise | Custom capacity | Arranged with the team |
Each connected destination counts separately, even if all belong to one organization. Subscriptions offer monthly or annual billing and a trial without a card. Agency also includes a 10,000-post scheduled capacity and additional-profile options.
