Support
A person answers.
Zyncast is small enough that support isn’t a ticket queue. Tell us what happened and we’ll tell you what went wrong — usually the same day.
Message us in the thread
If you're already using Zyncast, send HELP in your WhatsApp thread. It's the fastest route — we have your account context in front of us.
Email support
Not on the beta yet, or need to send screenshots and files? Email us and a person replies within one business day.

Found a security issue? Write to us directly. We acknowledge within 24 hours, we won't take legal action against good-faith research, and we'll credit you if you'd like.
security@zyncast.comWhat usually goes wrong
A post failed to publish
Zyncast tells you in chat which account failed and why. The three usual causes are an expired connection (reconnect the account in your dashboard), a file the platform rejected — TikTok and Instagram are strict about length and aspect ratio — or a platform rate limit, which we retry automatically. The other platforms in that post still went out.
Zyncast isn't replying on WhatsApp
Check you’re messaging the number we sent you, from the number registered to your account. If both are right, WhatsApp occasionally delays delivery — give it a minute, then email support@zyncast.com and we’ll look at the webhook log for your number.
I connected the wrong account
Open your dashboard, disconnect it, and connect the right one. The old token is deleted immediately. Scheduled posts pointing at the removed account are paused rather than published, and we’ll flag them in chat.
I want everything deleted
Message DELETE in your thread, or follow the data deletion instructions. Connections are revoked immediately and everything else goes within 30 days.
Instagram won't connect
Instagram only allows publishing from Professional accounts — Business or Creator — that are linked to a Facebook Page. Switch your account type in the Instagram app, link the Page, then try again. This is Meta’s requirement, not ours.
Can I get a feature added?
Yes, and during the beta it genuinely moves the roadmap. Send it to hello@zyncast.com or say it in your thread.
Not on the beta yet?
Add your name and we’ll message you when a spot opens. Free while the beta runs, nothing to install.
