Why it matters
A colleague can do different things for different people. Sofia drafts a follow-up email — but it should come from your address, not a teammate’s. Max checks Salesforce — but it should use your CRM access, not a colleague who’s not on the deal. Without user mapping, the colleague has to guess. With it, they know.Auto-matching by email
Most user mappings happen automatically. Eluu compares the email address on each Slack user with the email address on each Eluu user. If they match, Eluu links them. You don’t have to do anything for this to work — when you set up the Slack connection, Eluu syncs the workspace’s users on its own. The user-mapping page shows you what’s been linked.Manual mapping
A few people on your team might use different emails for Slack and Eluu, or sit in odd corners of your identity setup. For those:Find the unmapped Slack user
Anyone not mapped shows a red dot next to their name with the label
Not mapped.Blocking a user
If someone on Slack shouldn’t be using your colleague at all, you can block them. In the People section, find the user, click the three-dot menu next to their row, and pick Block. The colleague will ignore that user’s mentions from then on.Unmapping
If a mapping turns out wrong (someone left, identity changed), unmap them: same three-dot menu, Unmap. Eluu no longer recognises the Slack user; the colleague will respond as if to an unknown user, but won’t have personal context.Where to next
