In the Domain Health Center, you’ll find important information that allows you to verify critical details about your mailbox setup, essential for building a strong email reputation and reducing the risk of being marked as spam.
Authentication
SPF, DKIM, and DMARC may sound technical, but they’re simply email authentication methods that prove to Internet Service Providers (ISPs) and mail services that you’re authorised to send emails from your domain. These methods also help ensure that your email sending server is using your domain legitimately. Having these 3 protocols properly configured are essential for email deliverability.
- SPF (Sender Policy Framework): SPF authentication works by strictly specifying the number of allowed domain IPs that can send emails from your domain. While setting up SPF, the domain owner can add a file or record on the server which tells the receiving server what domains are actually allowed to send emails.
- DKIM (DomainKeys Identified Mail): DKIM authentication is similar to SPF the DKIM is added as a TXT record by adding it to your domain panel. It makes sure that none of the emails going from server to server is not tampered with by anyone in the middle and that email can be clearly identified from the other end.
- DMARC (Domain-based Message Authentication): DMARC builds on SPF and DKIM to validate emails further by matching the validity of SPF and DKIM records. This enables you to set policies and get generated reports in case the DMARC validation fails.
Profile name, Profile Picture, and account Age
These fields represent the basic information for your mailbox account. The Profile Name, Profile Picture, and Account Age all contribute to your mailbox’s trustworthiness. Accounts that are too new or lack a profile picture and name may be associated with spam or fraudulent activity, making them more likely to be flagged by spam filters.
Spam lists
Spam lists, also known as blacklists or blocklists, identify IP addresses or domains that have been flagged for sending spam. These lists are used by ISPs, mailbox providers, and anti-spam services to block unwanted emails.
💡Being featured on one spam list won’t typically harm your deliverability, as it’s relatively common. However, if your mailbox appears on two or more spam lists, it’s advisable to contact your email provider (e.g., Google or Outlook) and request a new IP address. This usually happens when you’re using a shared IP that has been flagged for spam in the past.
