If you are looking to send out advertising emails then you will want to ensure that as many of them as possible get through to the relevant people’s email inboxes. It is very easy for emails to be marked as spam and there are a number of reasons why this may happen. It could be that there is an issue at the server end and either the server IP has been blacklisted or the email address hasn’t been configured correctly. In the first instance ask your hosting company to check their end to see if everything is ok. If it is, then you should look at the information that is contained in your email.
Somw words are set up to automatically trigger spam filters and if you use these words or use them too often you may find that your emails do not get through.
If you are sending out mass emails then you should send them using a specialist email marketing company. Sending emails from your own hosting account could cause your IP to get black listed and this could then take your site offline too. Specialist companies will be able to advise you on what to include and what to exclude in your marketing email.
