60/100 — Workable, but mail from this domain is more likely to land in spam than it needs to be. Does not accept mail · Protected against spoofing
Findings
-
mx
No MX records. Mail sent to this domain has no defined destination.
Fix: Publish MX records pointing at your mail host.
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 include:amazonses.com include:532040.spf10.hubspotemail.net ~all
Fix: Move to -all once you have confirmed all senders are listed.
-
