As you probably know I am in charge of answering support request here at Maxprog. Quite often I am being asked about e-mail delivery issues, especially problems regarding apparently legitimate messages being flagged and blocked by spam filtering software. This particular issue is quite frustrating because most of the time you have no idea where the problem comes from. It is even more frustrating for me when people think the culprit is MaxBulk Mailer, maxprog bulk mailer software. There is no relation actually, MaxBulk Mailer is an e-mail client like any other.
In this post, I will try to gather all my knowledge about how to prevent running into this kind of problem. Let's see the typical story:
You composed your newsletter, as usual, you selected your subscriber list and then sent the message with a copy to yourself. You later found out that your copy never arrived and then, asking a few subscribers it turns out some of them did not receive anything either.
Does this story look familiar to you?
A message wrongly flagged as spam is called a false positive. A spam filter will check your message and will give it a score. If you reach a given score your message is flagged. Basically the spam filter will check whether:
Your message looks like spam
Your mail server is blacklisted
Your recipient list contains lots of dead addresses
If your mail server is blacklisted there are chances your message will never go through. How do you find out? Easy, MXtoolbox. That service will check your mail server domain or IP address with about 100 blacklists. Here you should get green OK icons on all lines. You should work on that overwise. Very seriously! All blacklist systems offer a way to get delisted.
Your recipient list contains lots of dead addresses
How old is your list? Where or how did you get it? Are you maintaining it regularly? Did you know those big mail servers like Gmail may flag a message sent to their server after reaching a given error threshold? That means that if your list has what Gmail considers too much dead/invalid addresses, the whole message will be flagged. You should check your list and remove bounces from it! Bounces are those delivery error e-mails you get in your inbox, don't ignore them! Remove the invalid e-mails addresses from the list right away. One solution is to verify the list with eMail Verifier at least once and then process bounces with eMail Bounce Handler as explained here.
Your recipient list contains spam traps
Spammers usually collect email addresses by using automated e-mail address harvester software. Those tools build lists out of web sites. Spam traps are specific email addresses placed on purpose so any e-mail messages sent to such type of address are immediately flagged and considered as spam. Finally, an anti-spam system may instantly block your whole message as soon as a spam trap is found. Nobody else will get it!... So, never harvest email addresses from the web and never purchase lists. Create your own lists!
Now I would like to talk about a great service I am sending all my customers to. It is called Mail Tester. This free service is literally for testing the 'spamminess' of your e-mails. You just need to send your message to an e-mail address they will give you. A few seconds later you will get a score and a detailed report of what is ok and what is wrong. That simple. You even get some directions to fix the problems. The best here is to try to get a score of 10/10. There are chances you will have to sign your messages with DKIM. Hopefully last versions of MaxBulk Mailer support DKIM. It is explained here: How to use DKIM with MaxBulk Mailer.
And remember to add an unsubscribe link to your messages. You can do that by installing our Mailing List Manager (MLM) on your web site. You can use MLM only to handle unsubscribes for local lists and ignore all the other features. When using MLM MaxBulk Mailer will add unsubscribe headers that Gmail will display automatically.
