Email domains

Send email from your own domain with SPF and DKIM verification.

To send email blasts and flow emails from you@yourgym.com instead of a shared Helios address, add and verify a sending domain under Settings → Email Domains.

Add a domain

1. Click Add Domain (or New Domain).
2. Enter your Domain, e.g. yourgym.com. Optionally set a custom Return Path Domain (e.g. pm-bounces.yourgym.com); otherwise the default works fine.
3. Helios generates the DNS records you need.

Verify DNS records

The domain page lists the records under DNS Records: an SPF Record, a DKIM Record, and a Return Path, each with the Type, Host, and Value to copy into your DNS provider (GoDaddy, Cloudflare, Squarespace Domains, etc.).

1. Add each record at your DNS provider exactly as shown. The copy buttons help avoid typos.
2. Back in Helios, click Verify DNS Records. DNS changes can take from minutes to a few hours to propagate; Refresh Status re-checks.
3. Each record flips to Verified, and the domain’s badge changes to Active.

SPF and DKIM are what mailbox providers use to confirm email claiming to be from your domain actually is. Without them, campaigns are far more likely to land in spam.

Point an inbox at the domain

Verification alone doesn’t change anything: assign the domain in each inbox’s Email Settings (Inboxes) and set the From Name and From Address (which must end in @yourdomain.com). From then on, that inbox’s email sends from your domain.

Maintenance

• Rotate DKIM keys from the domain page if your keys are ever compromised; you’ll need to update the DNS record afterward.
• If you change DNS providers, re-add the records and re-verify: a domain that loses its records stops authenticating.
