Question: I use 8.4.9 on a Mac. Lately all my e-mails from your program are going into the recipients spam folder? Is there anyway to stop this? I love this program I got used to it. Works great!
Answer: It would be interesting to diagnose your message. You can use that site: http://www.mail-tester.com. They generate an e-mail address you have to send your message to. You can then see your spam score.
Note that you are not alone fighting to get your messages delivered. Maxprog store for example, sends serials to purchaser, we had great problems with some servers including Gmail. I don't use MaxBulk Mailer but PHP Mail() function. I have added SPF and DMARC records to the maxprog.com domain DNS server. I also use DKIM. I have added maxprog.com at https://postmaster.google.com/ to monitor Gmail delivery,..etc... I am still receiving some messages from customers not getting the messages :-/ ... but much less than before.
The problem started in may when we started to use the Paddle store, I had to resend almost all messages to customers with Gmail addresses. Then I switched back to PayPal but the problem continued. It was not a problem with switching stores but a problem with Gmail system. Something has changed for sure.
I will very likely write a blog entry about that quite soon since I ran thru the problem and I got it partially fixed. I will also work on adding DKIM support to MaxBulk Mailer as I did with the code that sends serial fro our site.
