10 Tips to Prevent Salesforce Emails Falling into the Spam Folder

By Siva Devaki

Why do some emails go to the spam folder while others don’t? There can be a number of factors that can result in something going to spam. Here’s what you need to know about why Salesforce emails might be delivered to spam—and 10 tips for preventing this happening.

Why do Emails go to Spam?

Email service providers use a number of factors to identify potential spam emails. They will look at the subject line of the email, the content of the email, and whether the email comes from a domain or IP address that has a bad reputation. Email service providers trade blacklists back and forth containing suspicious email senders, and they also have a number of authentication services that are used to determine whether an email has truly been sent by the listed sender.

All of these factors are checked when determining whether an email is sent or marked spam. A single mistake could mean getting sent to trash.

Tips for Preventing Emails going to Spam

  • Check your email lists for dormant accounts. If your emails are getting bounced or ignored by an email address, it’s better to remove it entirely. It will only interfere with your metrics.
  • Use a recognizable sender name and a high-quality subject line. Your goal is to entice the user to click on an email, which they won’t do if it looks like a promotional query or an unsolicited message.
  • Check your email sender reputation. Your email sender reputation controls how much others trust you. You can use a number of tools to test your email sender reputation.
  • Verify your email lists and make it easy to opt-out. Make sure emails are verified to avoid dummy email accounts and make it easy for users to opt-out so they don’t instead mark your email as spam.
  • Avoid potentially “spammy” content. Certain overly promotional words, such as “make money now,” can be seen as spammy content. These emails are far more likely to be filtered out.
  • Make sure the subject line matches the content. If the subject line doesn’t match the content, then users may be inclined to mark it as spam once they have been disappointed.
  • Provide valuable and insightful email content. The more valuable and interesting your emails are, the more likely users are to engage with them. The more often your emails are delivered and read, the better your overall email reputation will become.
  • Check the reputation of your links. In addition to checking your own reputation, you also need to make sure your links have a high reputation as well. Otherwise, your entire email could be blocked.
  • Don’t include forms or attachments. Forms and attachments are often added with malicious emails so they can get your emails blocked entirely and your IP or domain blacklisted.
  • Use both plain text and HTML emails. Ideally, your emails need to be viewable on any platform. To ensure this, include both a media-rich template and a plain text template—Salesforce templates can help.

    The problem of attachments files uploaded to Salesforce site, PDF or others, and accessible / downloadable by an html file generates the passage of the mail in spam. That's the subject.
