Just like a direct sales letter, the subject line of your email is usually the most important part of getting your readers to actually read your email. If you have a compelling subject line the chance of your email improves dramatically.

According to a recent MarketingSherpa.com survey, 40% of email marketers said testing changes to just their subject line had a high impact on their return on investment (ROI). 45% said subject line changes accounted for a medium ROI and only 15% said that testing changes to their subject line results in a low ROI.

For every email you send you’ve got room for about 50 characters in your subject line so use them wisely to improve your open rates. Below are some tips to help improve your subject lines:

Test the subject line – Take a look at email campaigns you’ve sent in the past. Which subject lines worked the best and gave you the highest open and conversion rates? You might find that for a particular topic there’s a general trend or subject style that resulted in higher open rates.
The subject of importance – Try and put as much important and relevant information into your subject lines as possible. For example, if you’re sending out an email about a special offer make sure the product name and details on the offer appear in the subject line in a clear and concise format such as “$40 off ACME Widget Until – Today Only”.
Personalize the subject line – If you have details about your contacts then you can use them in your subject line to get their attention. A subject line containing the contacts first name can sometimes out-pull one that doesn’t.
Avoid spam keywords – Most email servers automatically filter out any emails that contain spam keywords in their subject line – Words such as free, stock, ebay, password, mortgage, etc all trigger spam detection software so keep them out of your subject lines at all times.
Trigger curiosity – The best way to improve your open rates is to pique the interest of your contacts. A compelling headline that entices them to open and read the contents of your email can do wonders for your conversion rate. Headlines that trigger curiosity can sometimes work well for example: “Hi [First Name] – I have a question for you.”.
Make the offer clear – If you’re making a special offer to your contact then be upfront and include it as part of your subject line. People love bargains and special offers so let them know about it before anything else.
Emphasize the benefits – We use this technique for our newsletters. We always use the format of “Newsletter – [Benefit]“. In our case, benefit is always the title of an article contained in the newsletter, such as “Company Newsletter – 10 Tips for Better Subject Lines”. It works every time
Easy identification – Make sure your contacts know the email is coming from you. Deceptive subject lines can confuse people so always try and including your company name in the subject line. Also, make sure you set the “From” attribute of your email to include your name and your companies name, such as “From: John Smith <john@acme.com>”.
Exclaim nothing – Avoid using excessive punctuation at the end of your subject lines. Google bans punctuation from AdWords ad’s for a reason – too much hype can annoy and confuse people.

That is normal when you send to yahoo accounts.

They do something called “Grey-Listing” which means they always reject the first attempt to send an email.

The second attempt will work (which your mail server automatically handles for you, you don’t need to do anything to make it go through).

See http://en.wikipedia.org/wiki/Grey_listing for more information about how it works.

When creating marketing emails, try using different text for both content and links. Also try re-positioning images such as logos and buttons. After sending about 3 different emails, compare the click-thru stats and see which one worked best. Now, when you need to send marketing emails in the future, you know that you will be sending the right mix of content and images that will attract the most click-thrus, and ultimately the most sales.

magine if John (an avid poker player) visits your website. You sell a book that helps him improve his poker game. He’s highly interested in what you have to offer, but he’s just not ready to purchase yet. He’s still recovering from that extended holiday and needs to pay off the credit card that he maxed out playing poker online.

He sees a form on your site asking if he’d like more detailed information, and so he fills in his name and email address. Within seconds an email is sent to John with a short summary of the benefits offered by your book and a couple of useful tips he can use right away.

A few days later, John receives another email that goes something like this:

“Hey John, I know you’re quite busy, especially with the holiday period coming to an end, but I just wanted to get in touch with you to let you know we’ve got a special coming up for that ‘How to win at poker’ handbook you’ve always wanted.”

John’s forgotten that he’d been looking to buy a book like this and this email reminds him that he needs to improve his game. John adds buying the handbook to his “To Do” list and goes about his daily business.

Another few days later, John receives another email; again, reminding him that the special is about to end alongside another juicy tip that’s in the book. John realizes he doesn’t have much time now, and goes off to purchase your “How to win at poker” handbook.

Every email sent to John was automated. You didn’t have to wait for him to subscribe, you didn’t have to personally address John, nor did you have to send him an email every few days.

The example above shows how a series of auto responder emails can be used as a powerful “hands off” marketing tool for your web site.

Now, take a few minutes and think to yourself, “How can I use auto responders on my web site?”

No, seriously. Stop and think. This simple exercise could easily add another stream of revenue to your web site that you didn’t know existed.

But I don’t sell anything online!

Auto responders can work for ANY business. You don’t need to be selling something online for them to work. For example, let’s pretend you have a hair styling business. You cater towards young men looking for a modern, attractive hair style. Part of your service includes helping them select a hair style that greatly enhances their facial features and gets them the compliments they’re after from the ladies.

On your website, you setup a simple form, something like: “Guys, get the hair style that’ll get you noticed. Free email report shows you how.”

Once John’s filled in the form, he gets an email with a summary of tips about the type of hair style suited for men with different features. It also mentions that you’re an expert in this field and your salon regularly helps men go from dud to stud in less than an hour.

A few days later, John receives yet another tip — this time on how washing his hair with a different shampoo can lead to different results. John starts to see how much of an expert you are, but also how much he’d rather just pay someone to take care of all this for him. He hasn’t got much time now since he’s started killing those poker sites. And so off he goes to call and make an appointment at your salon.

What else should I know?

The content in your auto responders need to be useful. Whilst including marketing hype purely about your product and services can work if there is a strong interest, you’ll usually need to provide relevant tips and information to keep your contact engaged and ready to pull out their wallet when need be.

You should opt to use personalization (custom fields), which includes the ability to address John by his first name, as that greatly increases response rates.

Finally, you should TEST your auto responders. Make sure they aren’t trapped by spam filters, make sure the contacts are receiving the auto responders in the order they’re meant to be and so forth.

Armed with this new knowledge, you should be able to add an additional stream of revenue that could do some serious boosting to your profits. Some online businesses use this single marketing strategy as the sole way of getting new clients. They do this because it works!

Now, have you decided how you’re going to use auto responders for your business?

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.

I also have a couple of email accounts with different web hosts that have spam filters in place. In particular, they mostly use spam assassin — a popular piece of spam filtering software. Spam assassin is useful because every email that it flags as spam is given a report and a list of why that email was considered spam.

I also have a local spam filtering application called No Spam Today! for Workstations, that runs a local copy of spam assassin on my PC. It acts as a very close replica to the same software used on thousands of servers world-wide. By sending myself copies of the newsletter No Spam Today! — using the spam assassin checking techniques — gives me feedback as to why my email may have been flagged. If I’ve used words or formatting that I shouldn’t have, or if I’ve included too many images, etc.

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, as well as conforms to spam laws in the United States. Contact information also allows a potential customer to contact you if need be.

Always 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.

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.

Being consistent with your timing of the newsletter also helps. For example, if you send a newsletter once per month (I personally don’t recommend you send out any more than this, unless you’ve got something really interesting to say), then aim to send it out at the same time, on the same day each month.

Once again, your potential readers will learn to expect your email, adding professionalism and often improving open rates, also reducing accidental spam flagging as well.

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 email is free, 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.

In this article I’ll describe the basic steps you can take to help reduce the number of emails you send out that get blocked by spam filters — hopefully resulting in a more rewarding marketing effort.

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.

Later in this article I will show you a technique that I use to help me detect words that could trigger spam filters that I may have missed.

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).

Try and use a short and simple stylesheet rather than using font tags excessively. Most spam filters don’t appreciate a multitude of font tags and inline formatting, and the more primitive filters can’t detect stylesheets so they will not penalize as easily.
