If you updated your DNS to point to our nameservers, and still don't see an "active" status for your domain inside ColdSend, the best thing to do is wait.
Behind the scenes, once your DNs points to our nameservers, we are setting up all the DKIM, DMARC, SPF records for you. And these records can take up to 24 hours to fully propagate. However, the average time is less than 1 hour.
If your domain is still pending verification after 1 hour, contact us at hello@coldsend.pro with your domain and the email from which you created your account. Our technical team will resolve your issue within 24 hours.
