You will send messages to people who have subscribed to your list. When you are sending them, you should remember that you have to include plain text, as well as HTML versions. This is due to the fact that some email clients will not accept HTML.
Be sure to use an autoresponder. In fact, there is no point in not using one. You will be just wasting your time if you do not use it. And it is very time consuming for you to send the message out one by one.
Another essential job you have to complete before you start your email marketing campaign is to check if your messages will be blocked by some spam filters. Sometimes the messages may also be blocked by the ISP. You will need to check about this carefully. There are also some autoresponder scripts which come with spam filter checker.
You should give some useful information to your subscribers otherwise they will lose the interest to read your messages receiving them for a few times. You can write something related to the products you are promoting. You may also try to write some how-to's in your message.
One other point you must bear in mind is that you should never forget to include your signature in the message. This is very important to remind your subscriber who you are.
Undoubtedly, you will include your URL and name in the signature file. In some case you may need to add your company name into. You should never make your signature more than five lines.
You should also remember to include your real name, as well as your physical address in the email. These are required by Law. You should also put a link at the end of each email so that people who receive the emails can have an option to unsubscribe.
