@Aleksi Last week we had send email along with the header to our email provider i.e. G Suite (Gmail) and today we have started receiving emails. Thanks
@Nick_Haschka Kindly contact gmail as it is rejecting incoming emails from Appsheet/Mandrillapp
@Phil we are also not getting email. Please help us to remove rejection of emails from Appsheet/Mandrillapp from our G Suite account.
We got it sorted out. Turned out our email server had bounced some emails during a hosting migration. When those bounces took place, the AppSheet/Mandrillapp mail server automatically blacklisted those addresses that had bounced and stopped serving them mail. AppSheet support was able to remove all the email addresses at our domain from the blacklist and we are back in business.
