Email in Proper Intervals
When we are marketing using emails, it would be best to keep them at a minimum or send emails at specific periods that will not become irritating for most. Getting emails everyday in your email box with nothing new to show can become entirely irritating and thus lead to potential cuts by people who choose to get updates or news.
There are companies who are aggressive and provide updates daily. But for the sake of relevance, it would be best to keep these practices at times where the real important emails are to be passed on for subscriber updates.
