How to Add a Custom Domain Sender Email in Flodesk

Edited

Learn how to add and verify a sender email from your own domain, so your emails look professional and meet authentication standards.

Why Use 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

Tip: If you don’t have a custom domain email yet, start with our guides:

Before You Start

By default, your Flodesk account login email is used as your sender address.
If this email comes from a free provider (like Gmail, Yahoo, or Outlook), you’ll see an “Unable to authenticate” message under My Account > Domain setup.

To fix this, you’ll need to add a custom domain email and verify it as your sender.

Add Your Custom Domain Email

Follow these steps to add and verify your sender email.

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 a panel to enter your sender details.

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.

Verify Your Email Address

  1. Check your inbox for the verification email from Flodesk

  2. Open the message and follow the prompts to confirm ownership

Didn’t get the verification email?

  • Check spam, junk, or promotions folders

  • Add help@flodesk.com to your email contacts

  • Go back to Email setup in Flodesk and click Resend verification email

Set It 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

Your Flodesk emails will now send from your custom domain by default.

Authenticate Your Domain

After verifying your email address, go to My Account > Domain setup

You’ll see your domain listed and ready for authentication. 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.
