Frequently asked questions
Is the Slack integration free?
Yes. It's available on every plan, including the free tier — you pay for your Climails sending, not per integration.
How long does it take to connect Slack?
A few minutes. Most connections are a couple of clicks or pasting a key — no developer needed.
Is my Slack data secure?
Yes. Credentials are stored encrypted, webhook payloads are signature-verified, and we only read the data needed to sync contacts and events.
Can I sync Slack in real time?
Yes. Native connectors sync on a schedule and webhooks deliver events in real time, so flows can fire the moment something happens in Slack.
Do I need to use every channel?
No. Slack data works with whichever channels you use — start with email and add SMS, WhatsApp, Telegram or push whenever you're ready.
