How to re-send external tester invitations on Apple's TestFlight service

Is there a way to re-send an invitation to an external tester on Apple's TestFlight Beta Testing service?

(I am referring to facility for external beta testing accessed via iTunes Connect, not to the standalone TestFlight service that has been provided since before Apple acquired it.)

Within iTunes Connect, under My Apps / Prerelease / External Testers, the tester's status just shows itself as "Invited". Unfortunately, this tester had a hyperactive spam filter that simply deletes all spam, so he cannot access the original invitation. And I cannot find any control on the TestFlight UI to re-send it. I have tried turning testing off and on, but this doesn't seem to help.

Try removing the tester and re-adding them:

Click the 'edit' button at to top-right of the testers table, and remove the tester:

Then add them back. This should resend the invite email.

// UPDATE: The interface has changed somewhat, though the process remains the same. Now after removing the external user, you must hit "save". Then add them, and hit "save" again.

Its a bit old query but the issue is still there. I have found an easy way out to resend the invites. All you need to do is to follow these steps:

1. Click on "Not available for Testing" and Save
2. Click on the Build that you want to test again. Save and Press Start Testing.

It will send invite to all the users. Hope that helps

If you invited yourself as an 'external' tester via a different email address, you can forward that email to the actual beta tester. It states:

> You can accept this invitation with the Apple ID that you are currently using. Your Apple ID and the email address to which the invite was sent don't have to match.

Caveat: back in iTunes Connect, YOUR email will show up as having 'Accepted' the invite, even if the Apple ID of the accepted device is associated with the original beta tester's email.

Apparently there's a huge brain-fart in Apples interface for signing up external testers:

Name and Lastname are listed as "optional", but if you leave them out, it looks like the invite is not being send (or maybe the mail gets formatted in a way so that it bounces for some recipients, I don't know, but after trying two different e-mails 5 times each with no luck, it finally worked for both when I added name and lastname).

Note that you can now resend invites easily through Itunes Connect:

iTunes Connect > My Apps > Your App > TestFlight
