Facts read from this source
-
Dkim signing Report an error
“We generate a signing key for your organization and sign every message you send with it; the public half is published as a TXT record under a selector that is unique to your organization.”
-
Dkim selector isolation Report an error
“And because each organization gets its own selector and key, your DKIM proof is yours alone, even if another customer sends from the same domain.”
-
Dns record splitter Report an error
“If your provider rejects a long TXT value as a single string, the DNS record splitter breaks it into the quoted segments it wants.”
-
Dns provider detection Report an error
“We detect your DNS provider and format the value the way that provider expects, so paste it as shown.”
-
Return path cname Report an error
“The return-path record sets your envelope-from (bounce) domain. Bounces and delivery feedback for your messages are addressed to this hostname, and pointing it at us lets us process them for you. The record also provides SPF alignment.”
-
Spf no apex record Report an error
“You do not need to publish an SPF record at your domain's apex (example.com), and the dashboard does not ask for one.”
-
Dmarc required Report an error
“We require a DMARC record to exist before the domain can send, and verify it by resolving your DNS directly.”
-
Dmarc policy generator Report an error
“the DMARC policy generator can help you write one”
-
Dmarc report analyzer Report an error
“the DMARC report analyzer turns the raw XML into something readable”
-
Tracking cname optional Report an error
“This record is not part of the send gate: a domain with verified DKIM, return-path, and DMARC can send even if the tracking record is missing. It only gates whether branded open/click tracking is available.”
-
Click tracking link rewrite Report an error
“When click tracking is enabled, links in your messages are rewritten to this hostname instead of a generic shared domain, which looks better to recipients and keeps link reputation tied to your brand.”
-
Domain verification schedule Report an error
“We check your DNS automatically after you register the domain, re-check every domain daily, and report per-record status on the domain resource and the dashboard.”
-
API dns records Report an error
“Open Email > Domains, then select your domain to view the records to publish. The API returns the same records in dns_records.”
-
Dns lookup limit advice Report an error
“SPF evaluation limits the number of DNS-querying terms to 10, so avoid adding an unnecessary lookup.”
-
Three records gate sending Report an error
“Three records gate sending: DKIM, the return-path CNAME, and DMARC. The optional tracking CNAME gates only branded open/click tracking and has no effect on sending.”
