Dear sir / madam, My name is Jarred Ladriere, and I've developed a Microsoft Outlook add-in specifically to check recipient emails before sending. The main purpose of this add-in is to double check each email addresses to avoid sending to wrong addresses and most importantly to avoid spoofing and phishing. I contacted you to see if you're interested in co-marketing/co-ownership of this add-in? Best regards, Jarred Ladriere
