What’s the impact of using Cloudflare, GoDaddy, or Route53 for email DNS?

Provider-specific considerations for email DNS:

Cloudflare:

Excellent performance and security

Proxy mode does not apply to email (uses DNS-only)

Good TXT record handling

Free tier sufficient for most email DNS

GoDaddy:

Adequate for basic email DNS

Some interface quirks with TXT records

Record limits on lower tiers

Route53:

Highly reliable, AWS-integrated

Pay per query (cost at scale)

Excellent API for automation

All three work fine for email DNS. Choose based on your overall infrastructure, not just email needs.

Different harbor authorities. All can file your manifests properly. Choose based on your fleet's other operational needs.
