Troubleshooting
Proxy status warning
Proxy status warning
Cloudflare’s orange cloud proxy does not apply to TXT or MX records — only to A/AAAA/CNAME records. Your DNS records will work regardless of proxy settings.
DKIM record is too long
DKIM record is too long
Some Cloudflare interfaces may truncate long TXT values when displaying them, but the full value is stored correctly. Copy the value directly from SendKit and paste it — don’t try to re-type it.
Already have an SPF record on the root domain
Already have an SPF record on the root domain
The SendKit SPF record goes on the
send subdomain, not your root domain. It won’t conflict with any existing SPF record on yourdomain.com.
