What We Check
SPF (Sender Policy Framework)
SPF specifies which mail servers are authorized to send email for your domain. Without it, spammers can forge emails from your domain, hurting your reputation.
DKIM (DomainKeys Identified Mail)
DKIM adds a digital signature to your emails, proving they weren't tampered with in transit. This builds trust with receiving servers.
DMARC (Domain-based Message Authentication)
DMARC tells receiving servers what to do with emails that fail SPF or DKIM checks. It also provides reports on email authentication.
Blacklist Check
We check major email blacklists to see if your sending IP is flagged. Being blacklisted can cause your emails to be rejected outright.
Frequently Asked Questions
Common causes include missing SPF/DKIM/DMARC records, being listed on blacklists, poor sender reputation, or sending too many emails too quickly from a new domain.
