Understanding the Error
What This Message Means
When you see "invite limit" error:
⚠️ Invite limit reached You've hit your Slack workspace invite limit.
What's happening:
You have too many pending invitations in Slack
These are invites that were sent but not accepted yet
Slack limits how many pending invites you can have at once
LaunchPass can't send more invites until you clear some
This is NOT:
A LaunchPass limitation
A problem with your LaunchPass account
Related to how many members you have
A billing issue
This IS:
A Slack platform limitation
Related to unclaimed/pending invitations
Something you control in Slack
Fixable in a few minutes
Why This Happens
Slack's Invite Limits
Slack has limits on pending invitations:
Free workspaces:
Typically 100-200 pending invites maximum
Varies by workspace age and activity
Conservative to prevent spam
Paid workspaces:
Higher limits (500-1000+ typically)
Still has limits though
Can request increase from Slack
Why Slack does this:
Prevents spam
Prevents abuse
Ensures invites are legitimate
Keeps platform healthy
Common Causes
You hit the limit because:
Many pending invites from previous signups
Members didn't accept invitations
Wrong email addresses (invites never opened)
Bulk signups that didn't convert
Free trial signups who didn't activate
Old invites never cleaned up
Rapid growth without cleanup
Most common: Old unclaimed invites accumulating over time.
Quick Fixes (Do These First)
Fix 1: Cancel Old Pending Invites
Clear out unclaimed invitations:
Step 1: Go to Slack workspace settings
Open Slack
Click your workspace name (top left)
Select "Settings & administration"
Click "Manage members"
Step 2: Filter to pending invites
Look for filter/dropdown
Select "Pending invitations" or similar
You'll see list of unclaimed invites
Step 3: Cancel old invites
Review the list - which are old/invalid?
Click on invite or three dots
Select "Cancel invitation"
Repeat for old/invalid invites
Cancel 20-50 invites to free up space
Prioritize canceling:
✅ Invites over 30 days old
✅ Obvious typos in email
✅ Free trial users who never converted
✅ Members who didn't respond
✅ Duplicate invitations
Keep:
❌ Recent invites (last 7 days)
❌ People you know are joining
❌ Active signups
Fix 2: Resend Important Invites
For members who need access:
Cancel their old invite (from above)
LaunchPass will auto-send new one when you clear space
Or manually resend from Slack
Member gets fresh invitation
This helps because:
Fresh invite = higher acceptance rate
Old invites might be lost in email
New invite gets attention
Fix 3: Clean Up Test/Fake Accounts
If you created test accounts:
Cancel invites to test emails
Remove test members if they joined
Frees up invite slots
Use real emails for testing going forward

Troubleshooting
"I Cancelled Invites But Still Hit Limit"
Why this happens:
Takes a few minutes to update
Didn't cancel enough
Need to cancel more
What to do:
Wait 5-10 minutes after canceling
Refresh your page
Cancel more invites if needed (aim for 50+)
Check again
Target: Cancel enough that you're at 50-70% of limit (leaves buffer).
"I Don't See Pending Invitations Option"
Why this happens:
Using wrong Slack interface
Don't have admin permissions
Looking in wrong place
What to do:
Try this path:
Workspace name → Settings & administration → Manage members
Look for "Invitations" tab or filter
If not there: Ask workspace owner
Admin permissions needed to manage invites
"Members Still Can't Join After I Fixed It"
Why this happens:
LaunchPass hasn't retried yet
Members need to wait for new invite
Different issue (not invite limit)
What to do:
Wait 1-2 hours for LaunchPass to retry
Check member email - invite might be there
Check spam folder - invites sometimes go there
If still nothing:
Contact [email protected]
Include member email
We can manually trigger invite
"Slack Won't Increase My Limit"
Why this happens:
Free plan has hard limits
Workspace too new
Previous abuse detected
What to do:
Upgrade to paid plan - Gets higher limits
Continue cleaning invites regularly
Work within limits - Cancel old invites daily
Consider other platforms if Slack limits too restrictive
Preventing Future Issues
Best Practices
✅ Clean invites weekly - Don't let them accumulate
