Getting started

1. Sign up on the sign-up page with your company or team name, an email address and the account ID you want.
2. Open the link in the email we send. Your access key is shown once: keep it somewhere safe.
3. Connect your social accounts, then post or schedule from each network’s tab.

Connecting accounts

Accounts are connected on each network’s own sign-in page. Castfrom never sees your password.

• Instagram: a professional account (Business or Creator) is needed. Personal accounts cannot be connected.
• Threads: any Threads account.
• X: any X account.
• TikTok: any TikTok account. Videos can be posted to your profile or sent to your TikTok inbox as drafts to finish in the TikTok app.
• YouTube: sign in with the Google account that owns the channel. To set custom thumbnails, the channel must be verified by phone on YouTube.

One social account can be connected to one brand at a time. To move it, disconnect it from the first brand, then connect it in the other.

Reconnecting

Networks let a connection lapse from time to time, for example when you change your password or the permission expires. The dashboard then marks the account “needs reconnecting” and we email you.

Open that network’s tab and connect the account again. Until then, scheduled posts to it fail and are kept in your queue marked as failed.

Scheduling and editing

• Choose “Schedule for” and a time when you write a post.
• Queued posts can be changed until they go out: the time, the text and the files.
• Posts queued for the same time on several networks can be moved together.
• Cancel a queued post to remove it. Nothing is published.
• YouTube videos are uploaded straight away and kept private until their time, then YouTube publishes them.
• TikTok posts cannot be scheduled yet: they go out when you post them.

If a scheduled post fails, it stays in your queue marked as failed and we email you the reason.

Media library

Upload photos and videos under Media, several at once. When you write a post, choose “Choose from media library” under the file field. For carousels, the order you pick is the order they appear.

Your numbers

• Castfrom reads each account’s numbers every hour: followers, and views, likes, comments, shares and saves for recent posts.
• Each post’s numbers are kept at 24 hours and 120 hours after it went out, so posts can be compared on equal terms.
• The best times to post are worked out from how your own posts did at each time of day and day of the week.
• Comparisons over 24 hours start once a day of records has built up.

Brands

One Castfrom account can run several brands. Each brand has its own connected accounts, dashboard, queue and media library. Switch brands from the menu next to the Castfrom logo.

Using Castfrom from Claude

Connect Castfrom to Claude to ask which posts did best, draft a post and schedule it, all in a conversation. Claude asks you before anything is posted, changed or cancelled. See Castfrom for Claude.

Safety limits

Castfrom posts through each network’s official API on behalf of everyone who uses it, so it guards against posting that networks treat as spam.

• The same text and files cannot go to the same account twice within 24 hours. On X, this also applies across your X accounts.
• If a network answers three posts in a day with spam or restriction errors, Castfrom pauses posting for that brand and emails you. Reply to that email to have it reviewed.
• Posting the same announcement to different networks is fine.

Access key

You sign in with your account ID and access key. We only keep a scrambled form of the key, so we cannot show it to you again.

If you lose it, email support@social-marketing.io from the address on your account and we will issue a new one.

Language

Choose your language from the menu at the top of any page. Castfrom’s emails to you follow the language you choose.

Closing your workspace

Choose “Close workspace” at the bottom of the dashboard. Everything is deleted 30 days later: the access key, connected accounts, post records and history. Until then it keeps working, and you can withdraw the request on the dashboard.

Disconnecting a single account only removes its sign-in. Details are in the Privacy Policy.
