- Verifying your domain is an essential step before you can send email through FLG.
- We ask all customers to verify domain ownership to:
- Ensure nobody but you and your organization can send from your domain
- Help improve email deliverability
- You only need to verify a domain once - after that, you can send from any email address at that domain.
- To verify a domain, go to Settings > Configuration > Email Domain Verification.

You'll see a list of email domains linked to your account, along with each domain's current verification status.
- This list is populated from:
- User email addresses
- Site email addresses
- Account settings business email address



Verifying a Domain
- Click Details next to the domain you'd like to verify to see its current SPF, DMARC and MX records.
- Click Verify to open a slideout with the steps to verify your domain - these steps are specific to your domain.
- Log in to your domain hosting provider (or contact whoever manages your domain) and update your DNS records as instructed.
- This process varies by DNS provider, so follow their specific instructions.
- If you get stuck, contact your DNS provider's support team first - if you're still having issues, reach out to us.
- DNS changes are usually picked up quickly but can take up to 24 hours to propagate back to FLG.
SPF and DKIM
- SPF records must be set up against your FLG subdomain, not the top level domain.
- Setting up SPF and DKIM records means FLG will be listed as a valid source of emails.
DMARC
- DMARC records must be set up against your top level domain to protect the entire domain.
- There are three DMARC policy options:
| Policy | What It Does |
|---|---|
| p=none (monitor) | Tells the recipient's email provider to take no action if an email fails DMARC |
| p=quarantine | Moves suspicious emails into a different folder, such as spam, instead of the inbox |
| p=reject | Blocks any email that fails DMARC so it never reaches the recipient |
- We recommend starting with p=none - this is what's shown in the slideout details.
- This lets you monitor emails sent from your domain and confirm all your email-sending services are whitelisted, without blocking genuine emails.
- Once you're confident everything is whitelisted, move up to p=quarantine, then finally to p=reject.
Records You'll Need to Enter
- MX Records - 2 records:
- Name/Hostname - flg
- Values - mxa.eu.mailgun.co.uk / mxb.eu.mailgun.co.uk
- SPF Record:
- Name/Hostname - flg
- Value - v=spf1 include:flg-mail1.co.uk ~all
- DMARC (ignore if already set up):
- Name/Hostname - _dmarc
- Value - v=DMARC1;p=none; rua=mailto:your-email@example.com
- CNAME:
- Name/Hostname - flg-c.flg
- Value - platform.flg360.co.uk
- DKIM:
- Name/Hostname - only the first part shown on the Email Domain Verification page in FLG (usually something like mta._domainkey.flg)
- Value - get this from the Email Domain Verification page in FLG
Once Verified
- The domain's status will update in the list.
- On the details page, you'll be able to see the full set of records configured for the domain.
