Verify your domain

Go back to your SendKit domain detail page and click Refresh. Vercel DNS changes typically propagate 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

Vercel DNS only works if your domain’s nameservers are pointed to Vercel. If you’re using Vercel for hosting but another provider for DNS, add the records at that DNS provider instead.
The DNS Records tab is only available for domains using Vercel as the DNS provider. Check your domain’s nameserver configuration.
