To avoid having your email marked as spam, keep clear of words such as ‘Free’, ‘$$$’, ‘Save’ and ‘Discount’ in your subject line.
Email marketing as many of us know, can be a powerful and inexpensive method of reaching our most active potential and/or existing customers. It can boost not only our direct sales, but also our credibility and referrals.
One of the major benefits of email marketing is that it is not costly, but obviously this is the same reason that spam has become so popular and so frustrating. With spam comes spam filters and with spam filters comes the blocking of legitimate email.
Some things that help avoid this:
1. The right selection of words – Many spam filters work by analyzing the email based on its content and the words used. Many words — such as free, sex and so forth — are very heavy spam trigger keywords. Your priority should be to avoid such words while keeping your newsletter as professional as possible.
2. Pay attention to your formatting
When formatting your email, keep it simple and professional. Excessive use of different colors, fonts, sizes, images and so forth will result in a higher spam filtering rate. Keep your email as clean as possible, and try to stick to a maximum of 2 or 3 different font types and sizes. Overly large sized fonts will surely add to an email being flagged as spam, as will too many images (or not enough text).
3. Be consistent – Use a template if you plan on sending newsletters consistently. This will make sure that all your newsletters look and feel the same. It will also add a touch of professionalism and branding to your newsletters.
Whilst not directly affecting spam filters, this will enable your readers to distinguish your newsletter instantly, thus not reporting it as spam accidentally. Some spam filters work by querying a spam server, whereas others report individual emails as spam. If your email gets reported as spam, then more than likely multiple spam filters will flag your email.
4. Use Double Opt-in
Try and make your contact lists double opt-in. This means that when a user subscribes to your contact list, they will be sent an email with a link that they must click on to confirm their subscription.
This is very important because many people can accidentally enter an incorrect email address, or even the email address of someone else on purpose. When that person receives a newsletter they did not subscribe to, they will assume they have been spammed, and your newsletter (and possibly your web server) will be reported as spam.
5. Unsubscribe and Contact Information
Every newsletter you send out should contain a way for the reader to unsubscribe. Not doing so is illegal in some countries and is an instant sign of spamming. You should also display your contact information (Phone, Fax and Address) clearly, as this greatly increases confidence in your email and your company
6. Test, Test, Test
The key to avoiding spam filters is testing. The first method of testing I use is to send the newsletter to multiple email accounts with existing spam filters. For example, I have a Gmail (http://www.gmail.com) account and a Hotmail (http://www.hotmail.com) account that I make sure I send my newsletter to. If the newsletter ends up in the junk folder, then I’ve got some work to do.
And the final word is that avoiding spam filters when sending out legitimate newsletters can be a time consuming effort. However, as your contact list grows, it can also be a very beneficial exercise. I’ve watched open rates of just 2 to 3% soar to a massive 50% and over, simply by applying the techniques described in this article.
