Apollo.io Setup

Apollo.io sends emails through your existing Google Workspace & Microsoft 365 accounts. Because of this, we just need to ensure SPF/DKIM are setup correctly with Google Workspace & Microsoft 365.

Email Provider Setup

First ensure that SPF & DKIM are setup correctly with your email provider:

Setup DMARC

Verify you don't already have DMARC enabled, you can do this with the Domain Check Tool.
If DMARC is already enabled, you're all done! Otherwise add the following DNS record:
Record Type
TXT
Host/Name
_dmarc.yourdomain.com
Value

v=DMARC1; p=none; rua=mailto:you@yourdomain.com

TTL
3600 seconds (1 hour)

Verification

Once setup, you can verify your SPF/DKIM/DMARC records are setup with the domain check tool.
Verify DNS records
Apollo also has a verification tool under Sequence Diagnostics. It currently recommends setting DMARC in quarantine mode without verification which I would not recommend until you have verified all services are properly authenticated.
