You might have noticed your VIP Club email campaign going to a spam folder.
Overall, this isn't a solved problem or one where there's a silver bullet. Individual emails can be marked as spam, and sometimes that's a false-positive.
There are small steps we can take to avoid having our emails being marked as spam in your various clients' email systems.
Avoiding Being Marked as Spam
We can increase the quality score of marketing emails, in general, by:
Ensuring the subject line is quality - not containing typical words that spam filters would flag as obvious.
Having the content within the email be quality.
Having the IP address of our sender MailChimp be in good standing. In general, the fewer bounces/undeliverable, the better, and fewer reports of 'this is spam' from readers.
Clients opening the email and training their email apps that you're a good sender. A good indicator is having your email address in their contact lists, or having correspondence with you in the past.
Here's some first-party detail from MailChimp about spam filters.
Background: Spam Filters
Emails being marked as spam are done at the email service provider level/
Spam filters are adjusting themselves every day, and it's difficult to predict what will give the best boost to the quality score of the email on a given month.
There isn't a standard, and spam filter makers are doing their job in trying to help their users/customers. They do this by constantly improving/changing set of rules that spam filters use, which are continuously improving due to the activity they see when analyzing spam. The rules and implementation is different between all the popular email providers. What is happening today at Google is different at Hotmail, which is different from Yahoo, etc. Some may be outsourced to a 3rd party spam vendor.
As time goes on, each of those filters will changes in various and subtle ways.
Focus On Your Open Rate Instead
One thing you can do is keep adding new clients to your list every month. Your email is likely to be opened by someone you just had an encounter with (via a mortgage application). We recommend to add new clients each month.
The more clients on your list, the more clients you will reach.
