What are the processes I need to go through to make sure emails sent from my web server are not rejected as spam? This question is for legitimate site emails that members have requested like a daily newsletter which is generated and run in a nightly process, as well as confirmation emails.
Some of the ideas I've heard are:
Here is a list of things you can do to prevent your emails being rejected as spam: Write to one person, No CC, No BCC, No Additional recipients. Address the person properly at the beginning of the email "Dear Clive" rather than "Hi m8". Avoid a deceptive subject line.
What is an email whitelist? To whitelist an email address just means you add them to your approved senders list. This tells your email client that you know this sender and trust them, which will keep emails from this contact at the top of your inbox and out of the junk folder.
Ok, I spend a couple hours this morning researching the answer to this question and here's what I discovered.
