Newsletters have been in place since before the dawning of the internet – it was actually a common method used by companies in order to keep their customers informed of deals and special offers. Of course at the time these newsletters were sent through physical mail. Because of this, companies were greatly limited on the amount of mail they could send; especially considering printing and postage costs.

As companies were able to recognize the benefits of doing business online, they quickly adapted everything for use on the World Wide Web including their newsletters. Not only did this allow companies to get in touch with even more potential customers via e-mail, it also gave them the freedom of being able to send out newsletters on a much more frequent basis. But at what point does the sending of newsletters start to feel like spam to the recipient? At what point does your computer begin spam filtering out these messages.

Quite frankly, as the publisher of an e-mail newsletter, you might not be given much room to work with from your readers or from your Internet Service Provider. Because internet users are receiving spam email on an unprecedented level, they are much more likely to mark your newsletter as spam if they feel as though you are sending it out too frequently – and of course this is going to vary greatly from user to user. Furthermore, ISPs may even choose to blacklist users who are sending out frequent, mass e-mails – even if your readers have signed up to receive such messages.
