How to automatically configure your domain

Automatically authenticate your custom domain to meet inbox provider requirements and protect your email deliverability.

Starting in February 2024, major inbox providers like Gmail and Yahoo require all bulk email senders to authenticate their sending domains using DKIM, SPF, and DMARC.

These used to be best practices — now they’re mandatory.

If you send emails from a custom domain email address (like you@yourdomain.com), you must authenticate that domain to:

• Comply with inbox provider requirements

• Prevent emails from going to spam

• Protect your sender reputation

Flodesk makes this easy with automatic domain authentication, powered by Entri, a trusted third-party DNS service.

Make sure you have:

• A custom domain email address (for example, hello@yourdomain.com)

• Login access to your domain provider (such as GoDaddy, Namecheap, Cloudflare, etc.)

If you don’t have access to your domain provider account, you’ll need help from the person or company who manages your domain.

Flodesk uses Entri to securely connect to your domain provider and automatically add the required DNS records for:

• DKIM (DomainKeys Identified Mail): verifies your emails weren’t altered

• SPF (Sender Policy Framework): authorizes Flodesk to send on your behalf

• DMARC (Domain-based Message Authentication, Reporting & Conformance): tells inbox providers how to handle unauthenticated emails

This method is recommended because it:

• Eliminates copy/paste errors

• Ensures records are formatted correctly

• Saves time compared to manual setup

1. Log in to your Flodesk account

2. Go to My Account > Domain setup

1. Find your domain card

2. Click Authenticate now

3. Select Automatically authenticate

1. Click Continue

2. Sign in to your domain provider through Entri

3. Approve access so Entri can add DNS records for you

Entri will automatically detect your provider and apply the correct settings.

Once complete, you’ll be redirected back to Flodesk and see one of these statuses:

• Pending

• Partially verified

• Verified

Important: DNS changes can take up to 48 hours to fully propagate.

It’s very common to see “Partially verified” during this time.
You do not need to restart the process.

Most delays are caused by how certain providers handle DNS prefixes or existing records.

That guide walks through:

• Common provider-specific issues

• Prefix formatting problems

• How to confirm records were added correctly

If needed, you can also:

• Ask your domain host’s support team to add the records for you

• Switch to manual authentication using Flodesk’s copy-and-paste instructions

Flodesk’s one-click authentication supports most major providers, including:

If your provider isn’t supported, you’ll automatically see the manual setup option inside Flodesk.

• You can reach out to your domain host's support team for assistance in adding the verification records for you, or

• You can manually enter the verification records by following this step-by-step guide.

To meet inbox provider requirements and protect your deliverability, all Flodesk users must authenticate their custom sending domain.

To automatically authenticate your domain:

1. Go to My Account → Domain setup

2. Click Authenticate now

3. Choose Automatically authenticate

4. Connect your domain provider via Entri

5. Wait up to 48 hours for full verification

Authenticating your domain helps your emails land in the inbox.

Do I need to authenticate my domain to use Flodesk?
Yes. If you send emails from a custom domain, authentication is required to meet Gmail and Yahoo standards.

What does “automatically authenticate” mean?
Flodesk connects to your domain provider using Entri and adds the required DNS records for you. No manual copying needed.

Why does my domain say “Partially verified”?
DNS changes take time to propagate. This is normal and usually resolves within 48 hours.

Should I try authenticating again if it’s not verified yet?
No, first wait 48 hours after verification. Re-running the process won’t help and may delay verification.

What if automatic authentication doesn’t work?
Review the troubleshooting guide first. If needed, you can switch to manual authentication.

Does authenticating my domain improve deliverability?
Yes. Domain authentication builds trust with inbox providers and reduces spam placement.
