Many people may have a lot of work to do in this area, but even if your rates have stayed relatively unchanged, there are still major opportunities to improve your deliverability and increase revenue.
Here is how:
Stay ahead of the deliverability curve -- The rules of deliverability are complex and always changing. The constant cat and mouse game between spammers, internet service providers and spam filtering companies ensure that there will always be new methods to sort the good senders from the bad ones.
Analyze your deliverability data -- Deliverability decisions are data driven, and it can be challenging to find out exactly why you're seeing inbox failure. Doing deeper analysis on your subscriber engagement data can yield huge results. For example, some segments of your subscribers may be more tolerant of higher frequency where others may not.
Monitor your reputation -- It sounds simple, but in most cases managing one's email marketing reputation is not that straightforward. Remember, it's the marketer's job to manage his or her own sending behavior since most deliverability issues occur from a breakdown in subscriber engagement and feedback.
