Prerequisites

Before you begin, make sure you have:
  1. A SendKit account with a domain added
  2. Access to your Cloudflare dashboard
  3. Your domain’s DNS records from the SendKit domain detail page

​
1. DKIM record

​
Verify your domain

Go back to your SendKit domain detail page and click Refresh. Cloudflare DNS typically propagates within a few minutes.
If verification doesn’t succeed immediately, wait a few minutes and try again. SendKit also checks automatically in the background.

​
Troubleshooting

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.
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.
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.
