Tools

bimi_check
Check if a domain has a valid BIMI (Brand Indicators for Message Identification) DNS record. BIMI allows brands to display their logo next to authenticated emails in supporting email clients.
shallow
blacklist_check
Check if a domain or IP address is listed in popular email blacklists (DNSBLs). Being blacklisted can severely impact email deliverability.
shallow
cname_lookup
Look up CNAME (Canonical Name) records for a domain. Shows where a hostname aliases to.
shallow
dkim_check
Check if a domain has a valid DKIM (DomainKeys Identified Mail) DNS record for a given selector. DKIM allows the receiver to verify that an email was sent by the domain owner.
shallow
dmarc_check
Check if a domain has a valid DMARC (Domain-based Message Authentication, Reporting & Conformance) DNS record. DMARC tells receiving servers what to do with emails that fail SPF or DKIM checks.
shallow
dmarc_generate
Generate a DMARC DNS record for a domain. Returns the record name, value, and type ready to be added to DNS.
shallow
dns_lookup
Look up all DNS records for a domain in one query. Returns A, AAAA, CNAME, MX, NS, TXT, and SOA records.
shallow
imap_check
Test an IMAP server connection by attempting to connect and authenticate. Use this to verify email receiving configuration.
shallow
imap_finder
Look up IMAP server settings (host, port, encryption) for a given email provider. Use this to find the correct IMAP configuration for services like Gmail, Outlook, Yahoo, etc.
shallow
mx_lookup
Look up MX (Mail Exchanger) records for a domain. Returns the mail servers and their priorities.
shallow
ptr_lookup
Reverse DNS lookup. Find the hostname associated with an IP address. A valid PTR record is important for email sending reputation.
shallow
smtp_check
Test an SMTP server connection by attempting to connect and authenticate. If from_email and to_email are provided, the tool may attempt to send a test email. Only provide these fields if you are authorized to send from the account and intentionally want to test full sending capability.
shallow
smtp_finder
Look up SMTP server settings (host, port, encryption) for a given email provider. Use this to find the correct SMTP configuration for services like Gmail, Outlook, SendGrid, etc.
shallow
spf_check
Check if a domain has a valid SPF (Sender Policy Framework) DNS record. SPF specifies which mail servers are authorized to send email on behalf of a domain.
shallow
spf_generate
Generate an SPF DNS record for a domain based on the email provider being used. Returns the record name, value, and type ready to be added to DNS.
shallow
txt_lookup
Look up all TXT records for a domain. TXT records contain SPF policies, domain verification tokens, DKIM keys, and other metadata.
