Post long-form threads to X / Twitter, Threads, and Bluesky

Description

Fully automated pipeline where you send an email to yourself with a rough idea (subject contains “thread”), n8n’s Gmail trigger picks it up, OpenAI ChatGPT rewrites/apply a viral-thread template, and Blotato posts the long-form thread to X/Twitter, Bluesky, and Meta Threads (optionally schedule or include images/videos). Template is easily extensible to other social platforms.

Who Is This For?

Digital creators, content marketers, social media managers, agencies, entrepreneurs, and influencers who want fast, automated long-form thread posting.

How It Works

1. Trigger: Gmail

• Connect your Gmail account.
• n8n monitors emails sent from you and filters for subjects containing the word “thread”.

2. AI Thread Writer: OpenAI ChatGPT

• Connect your OpenAI account.
• Prompt ChatGPT to clean up your draft and format a long-form viral thread.

3. Publish to Social Media via Blotato

• Connect your Blotato account and choose social accounts (X/Twitter, Threads, Bluesky).
• Schedule or post immediately.
• Supports optional image/video URLs via a mediaUrls array (publicly accessible URLs).

Example email to trigger the workflow:

Email Subject: thread Email Body: I'm obsessed with voice AI apps. Super Whisper is my current favorite because it runs locally and keeps my voice data private. I talk to it instead of typing. Way faster.

Setup & Required Accounts

• Gmail account (used as trigger)
  • n8n Gmail OAuth doc: https://docs.n8n.io/integrations/builtin/credentials/google/oauth-single-service
• OpenAI Platform account (access to ChatGPT)
• Blotato account: https://blotato.com
  • Generate Blotato API Key: Settings > API > Generate API Key (paid feature only)
  • Sign in to Blotato and create an API Key (required for posting)
• n8n:
  • Ensure "Verified Community Nodes" enabled in your n8n Admin Panel
  • Install the "Blotato" community node and create Blotato credentials

Optional: Media & Style Tweaks

• Attach images/videos: insert publicly accessible URLs into the mediaUrls array (advanced).
• To emulate a specific tone/structure, provide ChatGPT examples of your favorite viral threads or replace the example viral-thread prompt with your preferred example.
• Voice-to-text tip: record ideas (e.g., Superwhispr) and send the transcript by email — ChatGPT will clean it up.

Tips & Tricks

• During testing, use “Scheduled Time” in Blotato instead of immediate posting to preview before going live.
• Start with a single social platform while testing.
• If your script is long or includes media, processing may take longer.
• Many users prefer speaking their ideas (voice notes) then letting AI edit — faster than typing.

Troubleshooting

Check your Blotato API Dashboard to inspect each request, response, and error. Confirm API key validity, n8n node credentials, and that emails sent have subject containing “thread”.
