Email and SMS for Merch Drops: Lists, Consent and Sequences

Build the list before launch

The people who buy on launch day are mostly people who already knew it was coming. Social platforms decide who sees your posts; an email and text list is an audience you can reach on your own schedule. Start collecting before you have anything to sell.

Places to collect sign-ups:

• A coming-soon page with one field and one promise, such as early access to the first drop.
• "Notify me" on product pages, by size, so restock alerts go to the right people.
• A QR code at shows, pop-ups and the merch table, printed on a sign and on the insert card in every parcel.
• The link in every social bio, pointing at the sign-up page rather than the store's home page.
• Checkout, with a marketing opt-in box that is not pre-ticked.

Collect only what you will use: an email address, optionally a phone number for texts, and perhaps a size or a city if you tour. Keep email consent and text consent as separate choices, because the rules for each are different. Tag every sign-up with where it came from, so you know which sources produce buyers.

A confirmation step (double opt-in) for email costs a few sign-ups but keeps typos and fake addresses off the list, which helps deliverability.

Email rules in plain terms

In the US, commercial email is governed by the CAN-SPAM Act, which the FTC enforces. Its compliance guide for business sets out the main requirements:

• Header information (from, to, reply-to) must be accurate and identify you.
• The subject line must reflect what is in the message.
• The message must be identifiable as an advertisement, unless the recipient gave prior affirmative consent to receive it, which the statute itself exempts.
• It must include your valid physical postal address.
• It must explain clearly how to opt out, and the opt-out must work.
• Opt-out requests must be honored within 10 business days.
• You remain responsible even if another company sends the email for you.

CAN-SPAM does not require consent before you send, but sending only to people who signed up is better for your brand and for deliverability. Order confirmations and shipping updates are transactional messages, which the FTC's guide treats differently from marketing; keep promotions out of them.

Mailbox providers set their own rules on top. Google's email sender guidelines ask every sender to authenticate their domain with SPF or DKIM. A domain that sends close to 5,000 or more messages to personal Gmail accounts within 24 hours counts as a bulk sender, permanently, and must set up SPF, DKIM and DMARC, with one-click unsubscribe on marketing messages. A launch-day blast to a growing list can cross that line, so set it up early. Your email platform will walk you through the DNS records; do it before launch, not after a drop lands in spam.

If your list includes people outside the US, check the rules where they live, since many countries require opt-in consent for marketing email. This section is a plain-English summary of official sources, not legal advice.

SMS consent in plain terms

Texts are more tightly regulated than email, and the rules come from two directions: federal law and the wireless industry.

Federal rules. The FCC's rules under the Telephone Consumer Protection Act (47 CFR 64.1200) require prior express written consent before sending marketing messages with an autodialer, which the rules call an automatic telephone dialing system. As the regulation defines it, that consent is a written agreement, signed by the person (an electronic signature can count), that clearly authorizes the seller to send advertising or telemarketing messages to a specific number using that technology. The agreement must also tell the person that they do not have to agree as a condition of buying anything. Whether a particular texting platform counts as an autodialer is a legal question, but the industry guidelines below expect express written consent for every marketing text anyway, so collect it regardless. Other points in the same rules:

• A person can revoke consent by any reasonable means, and replies such as stop, quit, end, revoke, opt out, cancel or unsubscribe count. Revocations must be honored within a reasonable time not exceeding ten business days.
• One confirmation text acknowledging an opt-out is allowed, as long as it contains no marketing.
• Telephone solicitations may not be made before 8 a.m. or after 9 p.m. at the recipient's location, and the rules apply those restrictions to text messages sent to mobile numbers.

Some states have their own texting laws on top of federal rules.

Industry guidelines. The CTIA's Messaging Principles and Best Practices, which carriers and messaging platforms expect senders to follow, add practical detail. A sign-up form or keyword call to action should make clear what the program is, who is sending, any message and data charges, how to opt out, where to get help, and where the terms and privacy policy are. After someone opts in, send a confirmation that names the program, gives a help contact, explains how to opt out, says the messages recur and how often, and mentions any charges. Consent applies only to the program it was given for and is not transferable. Never text a list you bought, rented or were given. Keep records of each opt-in: the time, the method, the wording shown, the number and the campaign.

Your SMS platform handles much of this, including carrier registration of your sending number, which takes time to approve, so start setup well before launch day. This is a summary, not legal advice; for anything beyond a simple drop list, ask a lawyer.

A simple drop sequence

Five messages cover a full drop. Around them sit the transactional ones: order confirmation, shipping notice with tracking, and a delivery follow-up that asks for a review and a fit rating. How to launch a clothing drop covers the store side of the same timeline, and pre-orders vs in-stock drops covers the ship-date updates a pre-order needs.

Writing messages that get read

• Subject lines that say what is inside: "Drop 03 opens Friday at 6pm ET" beats a clever pun nobody understands.
• One message, one action. Every email and text should have one link that matters.
• Show the product. One strong photo above the fold, then the details.
• Texts are short: brand name first, the news, the link, and the opt-out reminder your platform requires.
• Only say what is true. "Almost gone" when it is not trains people to ignore you, and false scarcity damages trust you need for the next drop.
• Send at a time that suits the reader, in their time zone where your platform supports it.

Segmentation that pays off for drops

A small list does not need complex segments, but a few make a real difference:

• Buyers and non-buyers. Past customers often deserve early access; people who have never bought may need more of the story.
• Waitlist by size. A restock message to people who wanted Medium, only when Medium is back, gets clicks and avoids annoying everyone else.
• Location. For bands and events, a show announcement to people near the venue; for everyone, send times in the right time zone.
• Engagement. People who clicked recently can get the full sequence; people who have not opened or clicked in months get fewer messages, or a single check-in before you remove them.
• Text subscribers. Treat them as your most committed fans and text them rarely.
• Stockists and wholesale buyers. A separate list with separate news, never your retail drop blasts.

What to measure

Measure what connects to sales and list health:

• Clicks and orders per message, and revenue per recipient, which lets you compare messages sent to different-sized segments
• Unsubscribes and spam complaints per send, the early warning that you are sending too much or the wrong thing
• Bounces, which signal bad addresses and hurt deliverability
• List growth by source, so you invest in the sign-up points that bring buyers
• SMS opt-outs per message, which rise quickly if texts get frequent or pushy
• Sell-through after each message, from your store's reports, by size

Treat open rates with suspicion. Apple's Mail Privacy Protection downloads remote content privately in the background when a message is received, rather than when it is read, and hides the reader's IP address, so opens recorded for those readers do not reliably mean anyone looked. Clicks and orders are the numbers to trust.
