DNS propagation

DNS propagation is the time it takes for a DNS change to be visible across global resolvers, typically 5 minutes to 48 hours depending on TTL.

// IN PRACTICE

Don't start sending the moment a record is published. Wait until SPF, DKIM, and MX all resolve from multiple locations before warmup.
