Email Authentication Records
A small but helpful piece of the larger puzzle is to make sure you have an SPF, DKIM, and DMARC record setup in the DNS records for your email address domain.
Content
DMARC Record
You can use mxtoolbox.com to check your DMARC record.
You’ll want to set the DMARC record to: v=DMARC1; p=none;
This would be a TXT record, where the first value ( host name ) is _dmarc , and the second value ( points to content ) is v=DMARC1; p=none;
Record Type: TXT
Host / Name: _dmarc
Value: v=DMARC1; p=none;
SPF Record
LC Mail
You can use mxtoolbox.com to check your SPF record.
If you have setup your branded dedicated subdomain ( which we highly recommend ) this is an example of how your SPF record should look:
v=spf1 a:[[insert your branded dedicated subdomain]] ~all
Example: v=spf1 a:replies.yourdomainname.com ~all
Record Type: TXT
Host / Name: yourdomain.com ( root domain )
Value: v=spf1 a:replies.yourdomain.com~all
If you send emails through another platform(s), you'll want to include them as well. Example of a domain using Google Workspace for email services, and LC Mail for SMTP services:
v=spf1 a:replies.yourdomain.com include:_spf.google.com ~all
FGF Mail
You'll want to add your unique dedicated email sending subdomain to this, so it will look similar to this:
v=spf1 a:[[insert your branded dedicated subdomain]] ~all
Example: v=spf1 a:fgm.yourdomainname.com ~all
Record Type: TXT
Host / Name: yourdomainname.com ( root domain )
Value: v=spf1 a:fgm.yourdomainname.com ~all
If you send emails through another platform(s), you'll want to include them as well. Example of a domain using Google Workspace for email services, and FGF Mail for SMTP services:
v=spf1 a:fgm.yourdomainname.com include:_spf.google.com ~all
DKIM - *Google Workspace
Nuno shows how to create a DKIM record for a email address created through Google Workspace in the video above. The process for setting up this record is specific to your email service provider. You would need to check their knowledge base to see how to set up a DKIM record.
Here is Microsoft's support article going over how to setup a DKIM record for a business email addresses created using Microsoft's business email address services:
