When people talk about email marketing, lots of them forget to mention transactional emails. These are the automated emails you get in your inbox after taking a certain action on a website. This could be anything from filling out a form, to purchasing a product, to updating you on the progress of your order. Often, these are plain text emails that marketers set and forget.
Beyond that, avoid using all caps, too many exclamation marks, and hyperbolic phrases ("ACT NOW BEFORE TIME RUNS OUT!!!!"). Poorly formatted HTML in your emails can also hurt how they’re handled. Every spam filter is different, so an email might pass through one filter but get flagged by another. For more comprehensive info on how spam filters work and how to avoid them, check out this guide by MailChimp.
