How long does DNS propagation take?
Depending on TTL (Time-To-Live) cache settings, DNS updates propagate globally between a few minutes and 24 to 48 hours.
Why are TXT records critical for email deliverability?
TXT records store SPF, DKIM, and DMARC policies that prove emails actually originate from your domain, preventing spoofing and spam folder filtering.
