How to fix it
- SPF — Update the TXT record at slack.com (keeps your existing senders)
v=spf1 include:_spf.qualtrics.com include:mail.zendesk.com include:_spfextra.slack.com include:_spf.google.com -all
DNS changes can take up to 24–48 hours. Re-run the check afterwards.
Want it fixed for you? I set up SPF, DKIM and DMARC without breaking your other senders,
with a before/after report.
