Don't overuse images and always configure the alt text

Use a preference center
Sometimes, the person may even be interested in the content you share, but may not feel like receiving messages so frequently.

In these cases, to prevent the contact from unsubscribing and to avoid irritating them by having your message marked as spam, offer them the option of choosing the frequency.

Many automation tools allow this option, making it easier to manage reader preferences.

In the past, to assess whether an email had a high probability of being spam, filters would scan the content for suspicious keywords like "get rich," "make money," and so on.

As a result, spammers began to fool filters by using a single image in the body of the email, because these systems could not read the content of the figures.

Nowadays, filters are smarter and based on other factors as well, but too many images are still considered a red flag. To avoid this problem, try to use more text than images and always set the alt text field .

6. Make sure your HTML is cleanly coded and doesn't exceed 102k
Just as well-formatted code is essential for your blog's SEO, keeping your email HTML clean is a differentiator for the deliverability of your messages.

If you are in the habit of writing your email content in Word or Google Docs, check for tags like <span style=”font-weight: 400;”> and <span style=”background-color: transparent; color: inherit; font-size: inherit;”>. They add unnecessary information to the code, damaging the settings of the chosen template.
