How to handle the SSL delay with cloudflare subdomains

I am currently using cloudflares universal flexible SSL to put my WPMU network behind a SSL.

When a new site is added it automatically adds the CNAME for the subsite to cloudflare through the API but cloudflare takes a little while before the SSL becomes active and in the interim the site generates a certificate error and says it's unsecure.

Does anyone know a good way to handle this?

How would I go about delaying the welcome email by an hour to give the SSL time to initialize? Ideally I'd like to fire off an email saying we are processing order and then a follow up email saying its all been setup with the welcome details.

Any ideas?
