Add Your Reply Domain Records in Hostinger

Hostinger’s DNS editor lives in hPanel and takes all four records from one screen. It only manages your records when the domain is using Hostinger’s nameservers, which is the first thing to check.

Copy the real values from the domain screen in Know Reply before you start. Three of the four are unique to your domain.

Add the records

1. In hPanel, go to Domains and click your domain, then click DNS / Nameservers.
2. Under Manage DNS records, click Add record and select MX. Enter reply in Name, mx.sendgrid.net as the mail server, and 10 as the priority. Click Add Record.
3. Click Add record again and select CNAME. Enter the host with your domain removed, for example em1234.reply, in Name, and paste the SendGrid target in Target.
4. Repeat step 3 for s1._domainkey.reply and s2._domainkey.reply.

Hostinger appends the domain name automatically, so the Name field takes reply and s1._domainkey.reply, not the full hostname.

Check the nameservers first

If DNS / Nameservers shows custom nameservers rather than Hostinger’s, the records you add here are ignored and the live zone is somewhere else. Cloudflare is the usual answer. Add the records wherever the nameservers point instead, and use the Cloudflare guide if that is where they go.

Hostinger Email on the root domain

If you use Hostinger Email or Titan on yourbrand.com, its MX records stay exactly as they are. The new MX sits on reply.yourbrand.com and does not touch them.

Then check it

Hostinger’s documentation says changes can take up to 24 to 48 hours, which is a worst case. In practice this is minutes. Go back to the domain screen in Know Reply and click Check DNS.
