Hi, a number of clients have informed me that my emails are occasionally landing in their junk folders, which is leading to missing out on business and a major headache. I use Office 365 to send my emails and would have thought that given it's a paid-for service, that they should be doing their best to ensure deliverability. I've tried a few email hosts over the years, from the one that comes with our web hosting, Zoho, and now Office 365, and eventually, this problem always seems to come about. Here are the results from a couple of email checking services: https://app.mailgenius.com/spam-test/592edf https://www.mail-tester.com/test-uwzpybhny Is there anything I can be doing to help with the deliverability? Microsoft help suggested that I get an email header from one of my clients that had one of my emails land in their junk folder, but that's easier said than done!
