FAQs
What is DMARC, DKIM, and SPF?
DMARC (Domain-based Message Authentication, Reporting & Conformance) helps prevent email spoofing by allowing domain owners to define how email providers should handle emails that fail authentication.
SPF (Sender Policy Framework) is a record that specifies which servers can send emails on behalf of your domain.
DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, verifying that they haven’t been altered during transmission.
Does DMARC require both SPF and DKIM?
Technically, you can have DMARC with just one of them. Still, it’s best practice to implement SPF and DKIM to protect the most effectively against email spoofing and phishing attacks.
Should I use SPF or DKIM?
Both. SPF checks if an email comes from an authorized server, while DKIM ensures the integrity of the email content. Together, they provide more robust protection for your domain’s emails.
Can I create a DMARC if SPF and DKIM are not added?
Yes, you can create a DMARC record without SPF or DKIM, but it won’t be fully effective. These are necessary for DMARC to verify your emails properly. Without them, your emails are more likely to be flagged as spam.
What is the purpose of the Domain Scanner?
The Domain Scanner helps you check if your domain’s DMARC, SPF, and DKIM records are correctly set up. This ensures your emails are authenticated and reduces the chances of being marked as spam.
How does the Domain Scanner work?
Enter your domain and, optionally, a DKIM selector. The tool will check your domain’s DNS records for DMARC, SPF, and DKIM configurations and show whether they are set up correctly.
Do I need to know my DKIM selector?
If you have a DKIM record, it’s best to enter the selector for accuracy. However, if you don’t know it, the tool will still try to find it, but success is only guaranteed with the selector.
What if my domain lacks DMARC, SPF, or DKIM records?
The tool will tell you if any records are missing. You must add them through your DNS settings to improve email deliverability and security.
You will need an Email Deliverability Specialist to help sort these DNS records.
Why are MX records vital?
MX records direct emails to your domain’s mail servers. Without them, your domain can’t receive emails. The Domain Scanner checks if your MX records are valid.
How often should I use the Domain Scanner?
Use it when you change your DNS records or if you experience email issues. Regular scans can also ensure that your email authentication settings remain up to date.
