Hi @Wadic Engineer,
I checked in our system and I saw a hard bounce event for your email with the message
550: 550-5.1.1 The email account that you tried to reach does not exist. Please try double-checking the recipient's email address for typos or unnecessary spaces
It looks that we attempted to send an email to your email address at a time when it was not operational. The hard bounce informs us that the email does not exist and in this case, it is placed in a suppression list, as we no longer try to resend to non-existing emails.
I went ahead and removed the email from the suppression list, could you please ask one of your admins to resend the invitation now?
A new invitation needs to be sent, as the previous ones were dropped.
Please feel free to let me know if things are ok now and if you need anything further!
Just a heads up, I removed the email from your post to protect your privacy.
