It's one of the most-requested integrations we've ever shipped, with over 1,100 upvotes on the request. Little wonder, given the explosive growth we've seen on the platform over the past year.
Substack is fast becoming a powerful way for creators and brands to share, grow, and earn. So we're delighted to share that Buffer is now connected to Substack Notes.
Starting today, you can schedule, crosspost, and analyze your Substack Notes alongside your other social channels in Buffer.
Substack's growing fast. The platform now counts over 50 million total active subscriptions, with paid subscriptions more than doubling in the past two years.
And Notes — the short-form, in-network posts Substack launched back in 2023 to help writers reach new readers — has become one of the best ways to grow on the platform. But like most short-form formats, it rewards consistency. That's where Buffer comes in.
Kevin Indig writes Growth Memo, a weekly newsletter on SEO, AI search, and organic growth, read by over 29,000 founders and marketing leaders. Buffer handles distribution so every issue gets shared without him needing to be online — he estimates it saves him two to three hours a week, and he uses Notes to test ideas before turning them into full articles.
Daniel Hieber writes Linguistic Discovery , exploring the science and diversity of language. He treats Buffer as his content distribution center: every newsletter issue gets broken into microposts — Substack Notes, Threads, X — scheduled out over the following weeks, each one pointing back to the full issue.
