What are spam words?

Spam words are phrases or keywords in your subject line and email copy that email providers mark as malicious or spammy. These words activate the spam filters, causing your emails to land in the user's spam folder instead of their inbox.

Apart from the words, the context also matters. As spam filters are getting more advanced, they won't automatically send your emails to spam if they contain words like "discount code" or "claim your offer." But, you'll be in trouble if you.

  • Use lots of emojis exclamations.
  • Use all capslock, bright red fonts.

5 other tips to stay out of the email spam folder

Here are 5 crucial tips you should ensure to pass through spam filters:

• Ensure your email are authenticated: SPF, DKIM, and DMARC

Ensure that your emails are passing the following email authentication criteria:

Sender Policy Framework (SPF): SPF ensures that you send emails from an authenticated domain, not a relay server.

Domain Keys Identified Mail (DKIM): DKIM is an email security standard that ensures messages are not modified while traveling between the recipient and sending servers.

Domain-based Message Authentication, Reporting & Conformance (DMARC): DMARC is the actionable protocol. DMARC will take action when DKIM/SPF fails on your sender's domain.

• Run a spam check

Use spam checkers tools to scan the email content to ensure no content might trigger the spam filters. Use tools like SpamAssassin, Unspam email, or Mailgun. You can also run spam words tests on Gmail- Google postmaster. One of the tools that Google Postmaster has is Spam rate. It gives you an overall rate of how many emails are landing in spam versus email delivered.

Read how SBNRI reduced their spam rate with Mailmodo, leading to a 16% increase in open rates.

• Monitor your IP reputation

A low IP reputation can be due to IP blacklisting, getting hit by spam traps, or sending many emails without proper warmup. All these factors work as a red flag, triggering the spam filters. So, you must keep an eye on your IP reputation. Tools like Google Postmaster can help you monitor your IP reputation.

• Maintain a higher domain reputation

A higher domain reputation would mean that emails from your sender domain are less likely to be trapped in the email provider's spam filters. Hence, you will get higher deliverability. To monitor your domain reputation, you can use the Google Postmaster tool and get insights into how your domain performs among Gmail users.

• Practices email list hygiene

Email list building is crucial for reaching out to your subscribers but cleaning it consistently to maintain a healthy email list rate is equally essential. A healthy or hygienic email list is when you remove unsubscribed users so that you don't accidentally send them emails and risk landing in the spam folder. Besides, you should also suppress inactive and unengaged users by implementing a sunset policy to avoid sending emails despite user's disengagement.

• Make your emails engaging and relevant

Besides the technicalities, if your emails are not engaging and relevant to the recipient, they will either unsubscribe or stop engaging with your emails. And when you keep sending emails to such users, the mail provider sees your emails as spammy and puts them in the email spam folder.

So, put yourself in your audience's shoes, study their pain points, and behavior, and use that data to create emails that resonate to keep them engaged.

Conclusion

It's horrible to see all your time, efforts, and resources getting hit by the spam train just because you weren't aware of the words that might trigger the spam filters. But now you have the list you can refer to while writing your emails. Always keep this list handy, and you'll see higher deliverability.
