Why You Should Use Them
Both SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are methods that are commonly used to authenticate and improve email sending rate to your leads.
SPF record identifies which mailing servers can send email via your domain. This prevents anyone being able to send messages with forged From addresses of your domain.
DKIM is basically a digital signature that is added onto your emails, verifying and vouching for your domain name's authenticity. The signature is added to your message's header, so it won't impact content of your email anyhow.
We highly recommend you set these up before doing any mailing. It will improve your deliverability and help you avoid landing in spam and some nasty-looking warnings that Gmail users see when a domain isn't verified with these records.
Adding SPF and DKIM on Your Domain
Both of these are added as TXT records to your domain via DNS manager.
If you're using a transactional email service they will hand SPF and DKIM to you, and if you're using G Suite you can follow their guides to set these records up. You can find links to these on the bottom of this page.
Adding a TXT record looks something like this:
- Go to your 'My Domains' page, find the appropriate domain and click 'Manage'
- Click 'Advanced DNS' and the 'Add new record' button
- Select 'TXT record' and fill in host and value fields, click save when you're done
- Repeat the same process for adding both DKIM and SPF.
Note: This example was done on Namecheap platform, other platforms may have some different aspects but the core is still same. If you happen to struggle with adding these records be sure to contact our support and we'll be sure to help you out!
Setting up SPF is a part of creating your G Suite account, while you need to generate DKIM for your domain before adding it. Luckily Google has guides for both of these and you can find them here:
