When it comes to email marketing it is difficult to tell someone or a company exactly what the frequency of email distribution should be. Each business and audience will react differently. It is really up to you to figure out what that perfect frequency is.
The only way to really figure this out is to do as many tests as possible for a certain amount of time. keeping track of all statistics on opens and unsubscribes will be important. You will have to keep track of what time your email goes and and then analyze the data. Your best bet is to put all the info in a spreadsheet and do this for either three or six months to be able to make an accurate decision. After you have decided on a time frame to analyze this information make some small changes to your distribution schedule and then analyze the numbers to see what type of significant changes that occurred from the changes that you had made. This type of testing is very important so that your business is not missing out on any opportunities. Before you do this you will need to figure out if you want to send one or two emails out per day. Once you have made this decision then you can start to perform these tests. You could also as part of your test include increasing from one to two emails per week or the other way around.
