Everyone's glued to their smartphones these days, and that's why text message marketing is a total game-changer for small businesses. The Text-to-Join feature is the perfect way to reach your target audience right where they spend most of their time and help grow your email list and SMS subscribers simultaneously!
What is Text-to-Join?
Text message marketing is a direct way to connect with your customers. You use SMS (Short Message Service) to write updates, offers, or alerts and send them straight to their pockets. It's incredibly fast, and because it lands in a text inbox, your customers are way more likely to read it than an email buried in a promotions tab.
With Text-to-Join, customers simply text a keyword to your unique business mobile number to opt-in. It’s the ultimate "low friction" way to grow your audience.
Why should I use Text-to-Join?
Text-to-Join offers a convenient and effective way to grow your contact list in the "real world"—like at a checkout counter, a trade show, or on a physical flyer. By letting people join your list with a simple text, you capture high-intent leads who actually want to hear from you. Plus, who doesn't have a smartphone on hand these days? It's a no-brainer!
Constant Contact customer Tamika Catchings, owner of Tea’s Me Cafe, uses Text-to-Join to grow her list. “The text has been great,” says Tamika. You can hear her full story on how she builds community on the Be a Marketer podcast.
How do I set it up?
In 2026, the setup process has a few extra steps to keep you compliant with new mobile carrier rules:
Register for SMS: Before you can use Text-to-Join, you must register your business for SMS marketing. You’ll need your Employer ID Number (EIN) and a link to your website’s Privacy Policy.
Navigate to Forms: Once approved (usually 7–10 days), click Audience Growth > Sign-up Forms (or Channels > Sign-up Forms) in the left-hand sidebar.
Activate the Feature: Click Create a sign-up form and select Text-to-Join. Pick the specific list where you want your new fans to go and click Activate.
Share Your Instructions: Provide customers with your unique number and ask them to text the word "Join" followed by their email address.
The Rules of the Road
Mobile carriers are strict about protecting users. To keep your account in good standing, remember these SMS guidelines:
Double Opt-In: After texting "Join," the user will receive a confirmation text. They must reply "YES" to officially subscribe.
Quiet Hours: Federal law now mandates "quiet hours." In Constant Contact, we prevent marketing texts from being sent between 8:00 p.m. and 8:00 a.m. in the recipient's time zone.
The "Essentials": Every text must include your brand name, a "Msg & Data rates may apply" disclaimer, and instructions on how to opt-out (e.g., "Reply STOP to cancel").
Text-to-Join makes it easy for potential subscribers to join your world. Display your instructions next to your register, on a business card, or even on a napkin! Join the conversation and let us know how you're using Text-to-Join to level up your business!
