Hostinger

Publish the SPF, DKIM, and DMARC records MailBlastr generates for your domain using Hostinger’s DNS / Nameservers manager.

This guide walks through adding the DNS records MailBlastr generates for a domain using Hostinger. Add your domain in MailBlastr first to generate the records — see Managing domains — and keep the DNS records reference open for your exact DKIM record and region.

It is best practice to use a subdomain (e.g. updates.example.com) instead of the root domain for reputation segmentation.

Log in to Hostinger

  1. 1
    Open Domains

    Log in at auth.hostinger.com, select the Domains tab, and choose your domain from the Domain portfolio list.

  2. 2
    Open DNS / Nameservers

    Select DNS / Nameservers to reach the page where you manage DNS records.

  3. 3
    Add each record

    Use Add Record for every entry below — the DKIM TXT record, the SPF MX and TXT, and the DMARC TXT.

Hostinger’s Name field expects only the subdomain part — enter mailblastr._domainkey, send, and _dmarc, never the full …example.com. Hostinger appends your domain automatically.

DKIM — TXT

Add one TXT record holding your domain’s DKIM public key. Copy the value from your domain configuration page in MailBlastr.

DKIM — TXT
TypeTXToptional

A single DKIM key record.

Namemailblastr._domainkeyoptional

Hostinger appends .example.com, giving mailblastr._domainkey.example.com. mailblastr is the fixed selector MailBlastr uses.

Targetv=DKIM1; k=rsa; p=<public key>optional

The DKIM key record holding your domain’s public key.

TTL3600optional

Hostinger value used in these examples.

SPF — MX on the send subdomain

MailBlastr uses the custom MAIL FROM subdomain send.example.com. Set Type to MX, Name to send, paste the MailBlastr MX value into Mail Server, and set Priority to 10.

SPF — MX
TypeMXoptional

Receives bounce and complaint feedback for the MAIL FROM subdomain.

Namesendoptional

Resolves to send.example.com.

Mail Serverfeedback-smtp.us-east-1.amazonses.comoptional

Region-specific feedback host. Replace us-east-1 with your domain’s region.

Priority10optional

Use 20/30 if 10 is already taken on that host.

TTL3600optional

Hostinger value used in these examples.

SPF — TXT on the send subdomain

SPF — TXT
TypeTXToptional

SPF policy for the MAIL FROM subdomain.

Namesendoptional

Same host as the MX — resolves to send.example.com.

TXT valuev=spf1 include:amazonses.com ~alloptional

Authorizes Amazon SES for the MAIL FROM subdomain.

TTL3600optional

Hostinger value used in these examples.

DMARC — TXT on _dmarc

DMARC — TXT
TypeTXToptional

DMARC policy record.

Name_dmarcoptional

Resolves to _dmarc.example.com.

TXT valuev=DMARC1; p=none;optional

A monitoring policy to start with. See Implementing DMARC.

TTL3600optional

Hostinger value used in these examples.

Hostinger gotchas: enter only the bare Name prefix (send, _dmarc, mailblastr._domainkey), never the full domain; and never reuse an existing MX priority on the same host.

Once all six records are saved, return to MailBlastr and re-verify the domain. If it stays pending, see What if my domain isn’t verifying?.
