Can't invite team members: "Error sending invitation Unable to invite user. Invitation failed to send, please try again later."



Is anyone else having trouble inviting team members? We were able to add one person yesterday but now we can’t add anyone – keep getting this error message for everyone.

“Error sending invitation. Unable to invite user. Invitation failed to send, please try again later.”

We’ve tried multiple accounts and get the same message.

In looking through the forums I found this: Team members @handle can only be added to a dev account if:

The @handle is not suspended, protected, muted or blocked by the @handle account admin
The @handle must have a verified email address and allow emails
The @handle is not a member of any other dev account.
The @handle has not applied or been approved for their own dev account
If the @handle was invited to join the dev account, but then the invite was revoked, the @handle cannot be re-invited for 24 hours.

However none of this applies to us so we’re stumped. Any help is appreciated!



Sorry for the inconvenience. Are you still experiencing this error?

I will check with our team to see if we are experiencing any irregularities around this functionality.


We still experience the same error since 24 October 2018.


Our team is investigating this. More to come as we learn more.


Here is the detail of the request, hope this help

Thank you very much! I have passed this information along to our product team.

We are continuing to investigate this.


We’re having the same issue with @truthyatindiana, unable to invite team members. This has been the case for us since at least Nov 1. Any information on what’s happening? In case it helps: we’ve not tried to invite team members prior to this.


There are several reasons why an invitation might fail. Our team is currently reviewing this process and will be implementing improvements sometime soon.

In the meantime, we suggest for you to hold tight. Sorry for the inconvenience.


I had my Twitter Developer account activated today and cannot add team members just as the other people in this thread have mentioned. Are there any new updates?


Hi @k6epyrkLF4g9o2V - Our team is still working on this. Apologies for any inconvenience and thank you for your patience.


we are getting the same error as well…

"Error sending invitation

Invitation failed to send, please try again later."


Thanks for letting us know @yaamur_ads. Our team is still currently investingating this. I apologize for any inconvenience.


Are people really investigating this? The problem has been ongoing for nearly 4 months, so it sounds like it’s more than just a bug : )


Hi, Im having the same problem, any suggestions? thanks


Not at this time, but we’ll keep you updated as soon as we hear anything.
