WHAT NONPROFITS AND NGOS WRITE WITH POSTKING
Donor Updates, Impact Stories, Volunteer Posts and Campaign Announcements
One voice profile, trained on your organisation's own writing, used for every channel
Donor Updates and Impact Stories
Tell donors what their gift did. Paste your notes from the field or a short case story. PostKing drafts the update in your voice as a social post and a blog article. You check the facts and names before anything goes out.
Grant Report Summaries Turned Into Posts
You already wrote the report for the funder. Paste the summary section. PostKing turns it into plain-language posts for supporters, so the work you reported on reaches more than one reader.
Volunteer Recruitment Posts
Say what you need, when and where. PostKing writes the call for volunteers for each platform, plus a follow-up reminder. Use a landing page when you need a single link to share.
Campaign and Event Announcements
Plan the run-up to a fundraiser, an awareness day or a community event. Draft the announcement, the countdown posts and the wrap-up together. Schedule them to LinkedIn, X, Instagram, Threads and Facebook.
Multilingual Communities and Chapters
Write for the communities you serve in English, German, French, Spanish, Brazilian Portuguese or Czech. One plan covers 3 brands, so a chapter or a second programme can have its own voice. Built to grow your reach: more impressions on every update, and a steadily growing audience of supporters.
Be Where Your Customers Already Are
Customers do not live in one place. They scroll social feeds, type queries into search bars, and ask AI chatbots for recommendations. PostKing covers all three from a single brand voice model, instead of forcing you to run separate tools (or hire separate agencies) for each.
BUILT FOR SMALL NONPROFIT COMMS TEAMS
A Content Workflow for Nonprofits and NGOs
From a field note or a report paragraph to a scheduled post
Your Organisation's Voice, Not a Template
Give PostKing your past newsletters, appeals and posts. It builds a voice profile from your own writing. New drafts use your words for the people you serve, not generic charity language.
One Story, Every Channel
Start with one impact story or one paragraph from a grant report. Get a LinkedIn post, an X thread, an Instagram caption, a Facebook update and a blog article. Each one fits its platform and still sounds like you.
Volunteer Calls and Event Announcements
Need ten people for Saturday's food drive? Write the details once. PostKing drafts the recruitment post, the reminder and the thank-you. It also writes landing pages for campaigns and events.
Made for One Part-Time Comms Person
Plan a week of posts in one sitting. Schedule them to LinkedIn, X, Instagram, Threads and Facebook. Then get back to programme work. Growth costs $14.99 a month and covers 3 brands.
