DKIM stands for DomainKeys Identified Mail. It is a DNS record of CNAME type (default Hostinger Email DKIM records) and is used for signing and verifying the authenticity of emails. To be more precise, it involves adding a digital signature to outgoing emails that can be verified by the recipient's email server. This way, it prevents your emails from landing in the spam folders of your recipients.
If you use Hostinger Email with your domain, the default DKIM records are the following:
Type | Host | Points to | TTL |
CNAME | hostingermail-a._domainkey | hostingermail-a.dkim.mail.hostinger.com | 300 |
CNAME | hostingermail-b._domainkey | hostingermail-b.dkim.mail.hostinger.com | 300 |
CNAME | hostingermail-c._domainkey | hostingermail-c.dkim.mail.hostinger.com | 300 |
For subdomains, instead of the @ in the host field, enter the name of your subdomain; e.g. the DKIM records for the subdomain shop.domain.tld, will look similar to this:
Type | Host | Points to | TTL |
CNAME | hostingermail-a._domainkey.shop | hostingermail-a.dkim.mail.hostinger.com | 300 |
CNAME | hostingermail-b._domainkey.shop | hostingermail-b.dkim.mail.hostinger.com | 300 |
CNAME | hostingermail-c._domainkey.shop | hostingermail-c.dkim.mail.hostinger.com | 300 |
You can also find the value Hostinger Email DKIM records on the Emails section of your hPanel:
Click on the Manage button next to the preferred email account
Select Connect Domain on the left sidebar
Check the Increase email deliverability tab where the Expected records will be displayed:
To add these records to your domain, follow the steps depending on where your domain is pointing:
If your domain is pointing to Hostinger by nameservers, click on Connect automatically:
If your domain is pointing elsewhere by nameservers, you will need to add them manually, making sure to delete any existing DKIM records before adding the new values. Check our guides for some popular domain registrars here: How to Change DNS Records in Other Registrars
After making any changes to your domain's DNS zone, consider a few hours during which the DKIM records may be unavailablee due to DNS propagation. Once propagation is completed, your DKIM records will be fully operational 💡
