Check Your Spam Score Before Sending

Since every major mail service provider uses spam filters to some extent, it is considered a best practice to scan your email's subject and message content before sending to your marketing lists. Checking the spam score based on the email content, sender ID, SPF records, DNS settings, IP blacklisting, domain reputation, domain keys, DKIM, and PTR records is a great way to estimate deliverability and avoid the spam folder. This tool can accurately predict inboxing rates for Gmail, Yahoo, AOL, Hotmail, and most popular mail services worldwide.

This spam test tool will provide recommendations to improve IP and domain reputation and other factors which can limit email deliverability and prevent your messages from reaching the inbox folder. Open rates can also be improved by choosing a friendly subject name. Newsletters and marketing content is especially susceptible to spam filtering, so sending quality content and low risk messages can maintain good quality IP and domain reputations and healthy sender scores.

Tips for Improving Deliverability

Sending mail is somewhat of an art these days. Technical factors for the domain and IP address need to be set while also ensuring that the content of the email address fits certain standards to not trigger spam filters. The guide below will briefly touch on the best ways to improve deliverability rates.

  • SPF Record Setup - SPF records use a DNS TXT record to indicate all allowed hostnames and IP addresses that are authorized to send email on behalf of a domain. This allows mail servers to quickly determine if a sender is spoofing email from your domain, which can happen quite frequently. Learn more and setup your SPF record with this guide from dmarcanalzyer.
  • PTR Record Setup - PTR records can also be referred to as reverse DNS records. They are typically set with your hosting company so an IP address can resolve to a specific domain name. Ensuring that your IP address and domain have matching forward and reverse DNS records is a major boost to your sender score. Mail services use the PTR record as a significant spam filter.
  • DKIM and Domain Keys - This step can vary by your mail service provider, but most platforms now have 1 click enabling of DKIM and Domain Keys. DKIM prevents email spoofing by allowing the receiver to authenticate the sender of the message with a public DKIM key listed in your domain's DNS records.
  • IP Reputation - Email received from an IP address associated with spamming or unsolicited email marketing is a red flag for all mail service providers. It is recommended to frequently monitor your IP address reputation in addition to checking before mail drops. If your IP address is listed with any public blacklists online, there is typically a delist process that allows your IP to be removed within 24 hours. We recommend Multi RBL for checking if your server's IP address is blacklisted.
  • Validate Emails To Limit Bounces - Email hygiene is important, so the best way to ensure low bounce rates and healthy reputation with the mail service providers is to only include valid email addresses in your lists. Scrubbing invalid and deactivated email accounts can instantly improve your chances for reaching the inbox throughout an entire email marketing campaign. You can directly upload a list of mail addresses for email validation.
  • Remove Spam Traps - It's widely accepted that spam traps are a hidden killer of marketing campaigns. These email addresses are used as honeypots by mail service providers to capture unsolicited emails. It's recommended to cleanse spam traps from your marketing lists to avoid reputation issues.
  • SpamAssassin Filtering - SpamAssassin is a popular spam filter used as the foundation for most major mail service providers and is typically installed on shared hosting and dedicated server environments by default. As one of the most popular filtering systems, it's important to test against SpamAssassin rules and ensure your SpamAssassin score is under 3.

How To Prevent My Email From Being Marked As Spam?

Scan your email using the email spam test tool above to identify any potential issues with DNS records or even the message's content or subject line. Validate that your SpamAssassin score is as close to 1 as possible. Take the appropriate steps to solve these issues such as delisting your IP address from blacklists and removing spam traps. If all recommendations by our email spam checker have been completed, then move onto the next step of validating your contact lists.

Trusting an email validation service that can verify emails and also identify complainers, spam traps, and emails likely to bounce is crucial to maintaining healthy sender scores. You should never blindly message a list, even if you directly collected the email addresses yourself, as accounts can frequently change status, even more so for older lists. If a mail service provider notices a bounce rate over a certain threshold, they will route your future messages directly to the spam folder.

How To Reduce Email Bounces?

The best way to ensure low bounce rates is an industry best practice of validating email addresses as soon as they subscribe to your newsletter or contact list. Even legitimate users can make typos which would provide an invalid email address that increases your bounce rate. It's important to repeat validation every 3-6 months to identify deactivated accounts, complainers, and those that have been converted into spam traps.
