Announce in channels
Post team polls to Slack channels as Block Kit messages, with a link that opens the encrypted ballot.
format: Block Kit messages
Anonymous employee polls in Slack. Encrypted before they leave the browser.
Send anonymous employee surveys and pulse polls where your team already works. InviziPoll encrypts every response in the respondent's browser and stores ciphertext only. Slack is the delivery channel, not a shortcut around encryption.

Illustrative diagram: Slack delivers a message with a link to the poll. The answer is given and sealed in the respondent's browser, and we store only ciphertext, with no Slack IDs, names or IP addresses attached.
What you can do
Three ways to reach people, one encryption path
DM access codes
Distribute access-code polls via direct message for tighter eligibility than an open channel link.
eligibility: per-recipient codes
Remind without revealing
Send reminders without exposing individual response content to Slack, admins, or us.
reminders carry: no response content
BLUF: Privacy stays the same
What does Slack identity do?
Slack identity is used for delivery and eligibility, never to tie an answer to a person. Admins see results with no name, time or order attached. See security & encryption for the ciphertext boundary.

Common questions
Does InviziPoll work inside Slack?
Yes. Workspace owners connect Slack from admin settings, then distribute polls via channel posts or direct messages - responses stay encrypted in the browser with ciphertext-only storage.
Are Slack poll responses still anonymous?
Yes. Slack is a delivery channel only. Each answer is encrypted in the respondent's browser before upload, our servers never hold a readable one, and admins see results with no name, time or order attached.
Which plans include Slack integration?

How do I connect InviziPoll to my Slack workspace?
