Why You Should Check Your Newsletter Content for Spam Words
Email service providers like Gmail, Outlook, Yahoo Mail, Zoho Mail, Yandex Mail, Proton Mail, and others use algorithms to identify spam words. For example, Gmail reported that it blocks over 100 million spam messages daily.
Email marketing platforms, such as Mailchimp, Aweber, and ConvertKit, may also suspend your account if a significant portion of your emails are flagged as spam.
Why Do Emails Go to the Spam Folder?
Below are key reasons why emails are flagged as spam:
- Email Authentication: Email service providers use SPF, DKIM, and DMARC technologies to verify the origin and authenticity of emails. If you do not set up DKIM and SPF DNS records, your emails will go to the spam folder or may not even reach the recipient.
- Domain or IP Reputation: ESPs score email senders' IPs and domains based on their reputation. Domains with a bad reputation (those that send a high volume of spam emails or have a significant number of emails marked as spam) will end up in the receiver's spam inbox, no matter how good your content is. You can use Google's Postmaster Tool to check the reputation of your IP or domain for emails sent to Gmail personal accounts. A good reputation leads to better email deliverability.
- Email Encryption: Emails should be sent from an encrypted website, meaning your website should implement SSL/TLS. Most modern web hosting services offer free SSL certificates.
- Newsletter Content: The content in your email, including the subject line, body, and footer, plays a crucial role in email deliverability. Email spam filtering software analyze your content looking for siginals of spam content. Google, for example, says it uses TensorFlow to detect spam and block 100 million spam messages daily.
- New Domain or Email:If you're using a new email address or domain, it's essential to go slow on the number of emails you send. This will help email clients' systems learn about you. Some people recommend using email warm-up tools, but we are not sure how effective this is—give it a try.
Whether you’re a cold email sender, bulk emailer, or a small business, checking and eliminating spam trigger words from your newsletter message is among the many steps you should take to minimize the chances of it being flagged as spam and improve deliverability.
