🔒 Who can do this: Admins — domain verification is configured from Company Settings, which only admins can access.
Firehose sends drip campaign emails from your own domain rather than a shared sending address. Before you can send campaigns, your domain must pass verification. This article covers why verification is required and how to verify your sending domain.
Why domain verification is required
Sending from a verified custom domain improves email deliverability and ensures your campaigns pass spam filters. Unverified domains cannot be used to send drips.
How to verify your domain
Go to
Company Settings→Mail Domain.Click
Add Domainand enter the domain you want to send from (e.g. yourdomain.com).Firehose generates DNS records for you to add.
Add these records at your DNS provider (your registrar or hosting provider).
Return to the
Mail Domaintab and clickCheck Verification.
Verification status
Firehose checks several requirements before a domain can send:
SPF
DKIM
DMARC
MX records
A delivery test
The page shows you which checks are still outstanding. Once every check passes, the domain status updates to Verified. Until then, it shows as Pending.
💡 Note: DNS changes can take up to 24–48 hours to propagate.
Setting a default domain
If you have multiple verified domains, you can set one as the default sender for drip campaigns.
