<h2 id="h_01KS0H964D2KP5D3HGVZHP2BA7">What is an SPF record? Why should I use an SPF record?</h2>
<p>
A Sender Policy Framework (SPF) record allows Zendesk
to
send emails on behalf of your domain or website.
Without
an SPF record that includes Zendesk in your domain,
recipients
or email servers may block emails sent from Zendesk.
</p>
<h2 id="h_01KS0H964DZ7KANKFCTG2DV4ZH">
What is a DMARC configuration? Why should I use a
DMARC policy?
</h2>
<p>
Domain-based Message Authentication, Reporting, and
Conformance
(DMARC) works alongside SPF and DKIM to secure your
domain
or brand and ensure your emails reach your customers.
Without
DMARC, many strict email providers or clients may
filter
or reject your emails.

<h2 id="h_01KS0H964DZ2QPP03964XP8THE">
How do I check the email delivery status? How do

<p>
Check the recipients of the ticket for the delivery

delivery
failure in the ticket next to the name of the user
or customer.

How do I check my Suspended tickets view? How do

<ol>
<li>
Check whether the email appears in the Suspended

view, and check multiple pages if necessary.

<li>
Recover any ticket of your choice to inform the
spam
filter that the email is legitimate.

Why do customers not receive emails sent by agents?
Why does
the recipient server reject my emails?
</h2>
<p>
This issue happens when a delivery failure occurs,
when no
trigger or auto-reply sends the email, when email
forwarding
fails, when include:mail.zendesk.com does not appear
in your
SPF record, when DKIM records are missing, or when
a strict
DMARC policy rejects the traffic. To resolve SPF
errors,
ask your domain administrator to edit the existing
TXT record
to add include:mail.zendesk.com. If everything is
correct,
the relay server of the recipient may block incoming
emails
due to corporate filters outside the reach of Zendesk
Customer
Support.

Why do emails from end users not create tickets?
Why do I
not receive emails sent by customers?
</h2>
<p>
This issue occurs if the end user contacts an email
address
that does not appear in your email channel, if your
support
email address has a forwarding failure, or if the
messages
land in your Suspended tickets view. Additionally,
if the
email provider of the end user lacks properly configured
SPF, DKIM, or DMARC settings, the enhanced sender
authentication
setting may flag their emails as spam.
</p>
<h2 id="h_01KS0H964ENJ8TY5ZPTE8NF5RV">Can I have multiple SPF records for my domain?</h2>
<p>
No. You can only have one single SPF record per domain,
but
that single SPF record can include multiple sources.
If you
use multiple services to send emails, you must combine
them
all into one single SPF TXT record.

What is the recommended DMARC policy for monitoring
traffic?
What is the best practice for a new DMARC setup?
</h2>
<p>
It is best practice to start with a policy of p=none
to monitor
your email traffic. Once you verify that all legitimate
emails,
including those sent from Zendesk, properly authenticate
via SPF and DKIM, you can move to a stricter policy
of p=quarantine
or p=reject.
