Hmm the stock wording (which is what my screenshot shows) is not fool-proof because it doesn’t explicitly tell the user to check that their email is correct. I thought about it a little more and this wording may be better:
You’re almost done! Please follow the instructions in the activation email that we sent you.
If the email doesn’t arrive:
- Check your spam folder.
- Check that your email is %{email} (←what you typed in)
To be fair, I don’t think it’s possible to make the process 100% foolproof.
