To have your email account working with Hostinger, you only need to do a few easy steps:
If Your Domain Is Pointed Elsewhere via Nameservers
If your domain is pointed to another provider via nameservers, your DNS zone is also managed from there. For instance, if your domain is pointed to Cloudflare via nameservers, your domain's DNS zone is managed from Cloudflare.
As long as your domain is pointed to Hostinger by A record, the changes you should make to your DNS zone can be found in the Email Deliverability section on cPanel:
After making any changes to your domain's DNS zone, DNS propagation starts. Give it some time to complete, and your email service will be up and running smoothly 💡
If Your Domain Is Pointed Elsewhere via an A Record
Add cPanel MX records: since MX records of cPanel point back to your server IP, to use email services with us, follow this procedure:
Once this is done, your MX records will be pointed to our server 👍
cPanel TXT (SPF) record: the required TXT (SPF) record for cPanel can be found inside your DNS management zone, copy the record and add it to your active DNS zone.
