Email rules for studios: CAN-SPAM, unsubscribes and staying out of spam

When a studio emails its families about classes, camps or recitals, a few rules apply: the FTC’s CAN-SPAM Act, and the sender rules Gmail, Yahoo and Outlook use to decide what reaches the inbox. Here they are in plain English, each linked to the official source.

Updated

This is a plain-English summary for studio owners, not legal advice. If you’re unsure about your situation, ask a lawyer.

The law

CAN-SPAM: the US rules for commercial email.

The FTC’s compliance guide sets out what every commercial email needs. It applies to any business, and there is no exception for small senders.

  • Honest “From”, “To” and “Reply-To” details. They must identify your studio accurately.
  • An honest subject line that reflects what’s in the email.
  • Say it’s an ad when it is one, clearly and conspicuously.
  • Your physical postal address: a street address, a USPS-registered P.O. box, or a registered private mailbox.
  • A clear way to opt out, which must keep working for at least 30 days after you send.
  • Honor opt-outs within 10 business days. You can’t charge a fee or ask for more than an email address to opt out, and you can’t sell or pass on the addresses of people who opted out.
  • You’re responsible for anyone emailing for you. Hiring a marketer or using an email tool doesn’t move the responsibility.

The stakes are real: each email that breaks the law can draw a penalty of up to $53,088, the amount in the federal rules for 2026.

What’s exempt: transactional or relationship messages, such as confirming a registration, a change to an enrolled class, or billing for something a family already bought. These are exempt from most CAN-SPAM rules but still can’t have false routing information.

The inbox

Gmail, Yahoo and Outlook sender rules.

Breaking these won’t get you fined, but your email may not reach the inbox: Microsoft, for example, says non-compliant mail from high-volume senders may go to Junk or be rejected. The strictest rules apply to bulk senders; a small studio usually isn’t one, but following them anyway helps your email get delivered.

From each provider’s own sender pages, checked October 24, 2026. SPF, DKIM and DMARC are records your email tool or domain host sets up so providers can confirm the email really came from you.

What this means for a studio

  • Send from your own domain (like [email protected]), set up with SPF, DKIM and DMARC.
  • Use an email tool that adds one-click unsubscribe and removes people straight away.
  • Only email families who asked to hear from you, so few people mark you as spam.
  • Take addresses that bounce off your list.

Texts

What about text messages?

Texts follow different rules. Under the FCC’s rules for the Telephone Consumer Protection Act, a marketing text sent with an autodialer needs the person’s prior express written consent, and an opt-out request made in any reasonable way must be honored within 10 business days. The consent has to be a signed written agreement, though an electronic signature can count.

Whether your texting app counts as an “autodialer” is a legal question, so the safe practice is: get written opt-in to marketing texts, keep a record of it, and stop as soon as someone replies STOP. StudioAnchor Reach sends email only.

How Reach handles it

Built in, so you don’t have to remember.

  • Every marketing email carries an unsubscribe link and the one-click unsubscribe headers Gmail and Yahoo require.
  • People who unsubscribe are removed straight away and aren’t re-added by an import or an edit.
  • Reach asks for your studio’s mailing address before it sends a campaign.
  • Addresses that bounce, and people who report spam, are marked on their contact so you stop emailing them.
  • Studio and Pro send from your own domain.
  • The website sign-up form sends a confirmation email, so only people who confirm are added.

Questions

Does CAN-SPAM apply to a small dance studio?

Yes. The FTC says the law doesn’t apply just to bulk email: it covers any commercial email, like class promotions, camp sign-ups or recital merch. Messages about something a family already signed up for, like a schedule change for their enrolled class, count as transactional or relationship messages and are exempt from most of the rules, but still can’t be misleading.

How fast do I have to remove someone who unsubscribes?

CAN-SPAM allows up to 10 business days. Gmail’s sender FAQ asks bulk senders to process one-click unsubscribes within 48 hours, and Yahoo says within 2 days. Doing it immediately covers all three, and most email tools, Reach included, do it automatically.

Do I need a physical address in every email?

Yes, for commercial email. The FTC allows a street address, a post office box registered with the USPS, or a private mailbox registered with a commercial mail receiving agency.

Can I add parents to my list without asking?

CAN-SPAM itself is an opt-out law, but Gmail’s guidelines tell senders to make sure recipients opt in. In practice, add families who signed up with you, and ask before adding anyone else. People who never asked are the ones who press “report spam”.
