FAQ
What is a DNS lookup?
A DNS lookup queries the Domain Name System to translate a domain name into records such as IP addresses, mail servers, and text records. It retrieves records including A, MX, TXT, CNAME, and PTR.
What is email deliverability?
Email deliverability is the ability of emails to reach the inbox rather than spam or being blocked.
Why are my emails going to spam?
Emails can go to spam because of missing SPF, DKIM, or DMARC records, blacklist issues, poor sender reputation, or low engagement.
How do I test email deliverability?
Run an email deliverability test that checks DNS records, authentication such as SPF, DKIM, and DMARC, blacklist status, and SMTP configuration.
What is SPF?
SPF is a DNS record that defines which servers are allowed to send emails for a domain.
What is DKIM?
DKIM is an email authentication method that adds a cryptographic signature to verify message integrity.
What is DMARC?
DMARC is a policy that builds on SPF and DKIM to protect a domain.
What is an MX record?
An MX record specifies which mail servers are responsible for receiving emails for a domain.
What is SMTP?
SMTP is used to send emails between servers.
What is a blacklist (DNSBL)?
A blacklist is a database of domains or IP addresses flagged for sending spam.
