DKIM, SPF, DMARC DNS Verification Tool
This tool will allow you to check the DNS records you have setup for email authentication with ActiveCampaign. Please note that these records are not necessary for many accounts.
For more information on why you may want to setup authentication for your domain, check out our guide here.
This tool should not be used to check DNS/SPF/DKIM records you have setup for other email services like Gsuite or Office.
You can setup domain authentication for as many domains as necessary. If you have enabled "I will manage my own email authentication" within your ActiveCampaign Advanced Settings, you need to setup authentication for all the From Address domains you use.
Domain Alias (CNAME)
Enter your CNAME domain below. This can be any subdomain of your domain. You should place a CNAME record at this subomdomain that points to YOURACCOUNT.activehosted.com. Typically something like email.mydomain.com. Once this is setup, the subdomain can't be used for anything else.
CNAMES do not have a large impact on deliverability. The most common reason to setup a CNAME is for whitelabeling purposes, because this will change the login and link tracking domain (e.g. activehosted.com) to your own domain.
