To add an SPF record, you will need to manage your TXT records. The default SPF record for Hostinger emails will be:
- Host: @
- TXT value: v=spf1 include:_spf.mail.hostinger.com ~all
- TTL: default value
For Titan emails, check this article.
Once SPF record is successfully added propagation will start, which can last up to 24 hours to fully propagate.
