How to Add a Custom Domain Sender Email in Flodesk
Why You Need a Custom Domain Email
Sending from a custom domain email (like hello@yourbusiness.com) instead of a free email address (you@gmail.com) helps:
Build trust with subscribers
Improve email deliverability and sender reputation
Meet industry-standard authentication requirements from Gmail, Yahoo, and Microsoft

Important:
By default, your Flodesk account login email is used as your initial sender address. If your login email is from a free provider like Gmail, Yahoo, or Outlook, you’ll see an “Unable to authenticate” message in your My Account > Domain setup page.
To resolve this, you must add a custom domain email to use as your verified sender.
Step-by-Step: Add a Custom Domain Email as a Sender
Step 1: Go to My Account > Email setup
In your Flodesk dashboard, open the Email setup tab under My Account.
Step 2: Click "+ Add new sender"
This opens the sender details panel.
Step 3: Add your sender details
Enter your From name (what your recipients will see)
Type your custom domain email address (e.g., hello@yourbrand.com)
Click Save
Flodesk will now send a verification email to the address you entered.
Step 4: Verify Your Custom Domain Email Address
Check your inbox for the verification email
Open the message and follow the prompts to confirm ownership
Didn’t receive the verification email?
Check spam, junk, or promotions folders
Add help@flodesk.com to your email contacts
Return to Email setup in Flodesk and click Resend verification email
Step 5: Set as Your Default Sender (Optional)
Once your email is verified:
Click the three-dot menu (...) next to your new sender address
Select Set as default
Now, this custom domain email will be used by default when you send emails from Flodesk.
Step 6: Authenticate Your Domain
After verifying your email address, head to:
Your domain will appear and be ready for authentication setup. This includes:
DKIM (DomainKeys Identified Mail)
SPF (Sender Policy Framework)
DMARC (Domain-based Message Authentication Reporting & Conformance)
Follow this guide on domain authentication to complete the setup.
