Content can absolutely affect your deliverability! Many ISP spam filters will automatically review your email content & subject line to determine if it is spam. There is no magic rule or formula that you can follow to guarantee emails are delivered to the inbox, but you can exercise a little common sense and follow some simple guidelines to help your email marketing message get to the inbox.
It is a good idea to check back here frequently. We will be updating the article as we gain more insights and experiences.
- Keep your subject lines between 35 to 50 characters long. The longer your subject line, the more likely it will be flagged as spam.
- Don’t use ALL CAPITALIZED LETTERS in your subject line or body.
- Avoid sending messages that have only a single large image. Have a good balance of text and images. The more text you have regarding your images, the better.
- Make sure there are no spelling mistakes or HTML errors.
- Avoid using spammy type words such as ‘money’, ‘free’, ‘dollars’, ‘cash’, ‘limited time offer’, ‘medication’, or ‘pornography’.
- Avoid common spam tactics like using a dollar sign($) for the letter “s”.
- Limit the use of ‘click here’ links.
- Minimize the use of bold text, red font, exclamation points (!!!), questions marks (?) and symbols like $ € £ @
- Make sure your content is relevant to your offer and helps build rapport/credibility with your subscribers. Emails that are constantly off-topic and are nothing more than constant ads will impact deliverability and reception by your subscribers.
When we find autoresponder campaigns with messages that violate these guidelines, we may suspend the campaign until the issues are corrected. This will help us to make sure our focus is on helping responsible email marketers continue to experience outstanding deliverability rates.
