Add DNS records for email authentication

Follow these steps to add the DNS records required for SendGrid domain authentication. This ensures your emails are properly verified and reach your recipients' inboxes.

Hostinger

  1. Navigate to the Domains section → Domain portfolio. Then, click Manage next to the domain in question:

  2. Once on the domain management page, select the DNS / Nameservers from the left sidebar:

  3. At the top of the DNS / Nameservers section, select the tab **DNS records:**


    The DNS records tab leads to the DNS zone management, where you can add, edit, and delete records:

  4. Add a record
    To create a new record, enter the values for type, name, content, TTL, and any other additional information required, depending on the record type. Once it’s done, click Add Record:

We will provide the dns records to authenticate your domain.

Example of bsport dns records:

Type

Host / Name

Value

CNAME

CNAME

s1._domainkey.domain.com

CNAME

s2._domainkey.domain.com

TXT

_dmarc.domain.com

v=DMARC1; p=quarantine; aspf=s; adkim=r

⚠️ *When adding the CNAME records, enter only the subdomain part in the Host / Name field (e.g., em3784 or s1._domainkey), not the full domain. Hostinger will automatically append your domain

If you already have existing TXT records for DMARC or DKIM, check for duplicates before adding. Only one DMARC record should exist.*

After adding the records, let us know and we'll verify them in SendGrid. Propagation can take up to 24 hours. If you change the domain’s nameservers to a different provider, the DNS Zone management will move to where you pointed your nameservers.
