Here are our top tips to avoid the spam filter:
Watch out for the trigger phrases and words
To give your email the best chance of being delivered try to avoid including any words or phrases that might cause you to get caught in a spam filter. A few things to avoid include: over use of words like free, guaranteed, investment, and pharmaceutical. Overuse of phrases such as free delivery, money off and special offer.
Monitor delivery to accounts like Yahoo!, Hotmail and Outlook
When you set up your test group it's worth including a Yahoo!, Gmail, Hotmail and Outlook account. These email clients cover up to 83% of all the major email clients used so you have peace of mind knowing your email will deliver and render correctly across the board.
Ask your subscribers to add you to their safe list
Asking your subscribers to add you to their safe senders list will help ensure the subscriber's server won't catch your email in a filter and block it. Filters are updated and learn subscriber behaviour so being on a safe senders list will help ensure your emails are delivered every time.
Avoid using upper case font for entire sentences
Excessive capitalisation and punctuation is the equivalent of shouting at someone. It's also standard practise of spammers so avoiding this will help you get past the filers and into the inbox.
Don't over use bold text
Unfortunately another standard practise of spammers so it's a good idea to avoid doing this. If you want to highlight a particular area or phrase of text, linking it to a relevant website page or PDF will serve you much better. This will underline your text and you can change the colour of it, helping it to stand out. A descriptive link will also help improve the click through rates.
Avoid using very large or very small font sizes
Large fonts size are again the equivalent of shouting at someone. Although they may get their attention, it might not be for the right reason. Small font sizes is another common practice of spammers where they are also trying to avoid the filters.
Never embed images in your email
This makes the emails very large and difficult to deliver. Arrange for your images to be downloaded once the email has been opened. Most Email Service Providers should do this for you quickly enough that your subscriber won't notice the difference.
