Occasional Duplicate E-Mails

[Covene]

After running this script in production for a few days I found a potential issue with the script. There are occasions where a new client is found, an email is sent, and then on the next run through the script that new client disappears from the API response. On the next script run, the client returns in the API response, and it is counted as a new client therefore causing a duplicate email to be sent.
