How to share Slack developer sandbox with slackhack@salesforce.com?
one of submission requirements is share your Slack developer sandbox with testing@devpost.com and slackhack@salesforce.com
Slack UI says Couldn’t invite when I'm trying to invite this email to sandbox workspace.
Log in or sign up for Devpost to join the conversation.

Thanks for your patience! We’ll forward your query to the Salesforce team for a closer look. We'll be in touch as soon as we have more information.

Hi there. Can you confirm if you were trying to add both as "Members" and NOT as Single or Multi-channel guests? If so, let me reach out to the Slack/Salesforce team to see if there is another common troubleshooting solution we can try.

We also have this new FAQ which should help:
My sandbox is set up but invites aren't going through/teammates never get the email.
If you used the default template, your sandbox came pre-loaded with 7 placeholder users — which fills the 8-user cap before you can invite anyone else.
Two options to solve this:
Already provisioned your sandbox: Go to Manage Organization → People → Members → find the placeholder accounts → Deactivate this account (must be done at the organization level — removing from the workspace alone will not resolve the issue)
Haven't provisioned your sandbox yet: Choose the blank template — no fake users, full capacity from the start; or, if you want the content in the default template, follow the instructions above
Let me know if you try both of these and if you're still having trouble. Thanks.

I deactivated two accounts, and their status now shows as “Removed,” but I still can’t invite two new members

I checked with the Slack team - did you make sure to remove them from the org level, not the workspace level?
