It is important to deliver your email newsletters on particular days of the week and not on any day.

The email or the newsletter should reach a customer or a prospect at a time when he is able to spend some time reading it and deliberating on its content.

For different types of emails, different delivery timings are appropriate. Different types of emails can be either business to consumer type, or business to business type. For any mail reaching your work station, you should be in a position and frame of mind to read it and act on it as well.

The business to consumer type of newsletters, are best sent to the prospects and the consumers over the weekend. This is a leisure time and if not busy, people will generally read the message.

The best time for business to business type of newsletters reaching the prospects is somewhere in the midweek afternoons. The better days for these email messages to reach destination would be Tuesday, Wednesday or Thursday. This is a time when the executives are less pressurized and stressed about time. And there are fewer messages and emails seeking their attention. Sending it during the midweek period when the executive is a little less busy, you are in a way increasing the chances of the message being read.

A very bad time for the business to business newsletter reaching the prospect is Monday morning or even Friday. This is the time when the executive is trying to catch up on the backlog of the weekend mails and maybe planning for the projects coming up during the week. If it is a Friday then he is trying to finish maximum work, before leaving for the weekend.

Remember that the newsletter will be read only if the prospect has time to read it, so why not target for a time when he is most likely to be relatively free.

It would be worth a try to follow this strategy of email and newsletter delivery.
