How to Expand Your Reach with SMS Marketing | Subtext

Written by Subtext | Jul 17, 2025

Growing your audience is harder than ever. Algorithms change. Organic reach drops. Even your most loyal followers might never see your content. In a world where you’re constantly renting space on someone else’s platform, the smartest move you can make is to build an audience you own.

That’s where SMS and Subtext come in. With SMS, you're not fighting for visibility in a crowded feed or hoping your message makes it past a spam filter. You're delivering content directly to people’s phones, where 98% of messages are read, and engagement is personal and immediate.

Subtext helps you go beyond notifications. It gives you a direct line to your audience—no middlemen, no algorithms, just a platform designed for real connection. And because subscribers opt in, you're building a list of people who want to hear from you. That means you own the relationship, not a third-party platform.

In this guide, we’ll explore creative, actionable ways to use SMS marketing to expand your reach by growing your list, driving referrals, deepening engagement, and turning casual followers into loyal community sms members.

1. Use SMS as an Entry Point for Exclusive Content

People are more likely to subscribe to something that feels exclusive. Offering SMS-only content is a great way to build your list while giving your audience real value. This could include behind-the-scenes updates, VIP access, subscriber-only deals, or industry insights they won’t find elsewhere.

How to Make It Work:

  • Create a strong incentive. What’s in it for them? Whether it’s early access to news, a direct line to an expert, or exclusive deals, make the value clear.
  • Promote it across other channels. Let people know about your SMS list through email, social media, and your website.
  • Keep it engaging. If people opt in for exclusive updates, ensure they get high-quality content that keeps them engaged.

Real Life: Locked On Podcasts uses SMS as an entry point to deliver exclusive content that goes beyond the mic, giving superfans insider updates, bonus takes, and direct access to their favorite hosts. This direct connection deepened listener loyalty and helped expand their podcast audience through word-of-mouth and consistent engagement.

2. Use SMS to Engage & Convert Social Media Followers

Social media is great for visibility, but your audience doesn’t truly belong to you—it belongs to the platform. Driving followers to your SMS list gives you direct access to your audience without being at the mercy of an algorithm.

How to Make It Work:

  • Create SMS member sign-up opportunities in your social bio, posts, and stories.
  • Use lead magnets like contests or exclusive content to encourage sign-ups.
  • Leverage SMS to deepen engagement. Instead of relying on comments and DMs, offer an SMS number for direct conversations, Q&As, or VIP updates.

Real Life: Artist Perrie tapped into her Instagram following to promote her “No Tears Hotline,” inviting fans to call in for a unique, emotional connection. By blending vulnerability with creativity, she turned social engagement into a powerful, personal experience while using Subtext to build a deeper relationship with fans and grow her audience beyond the feed.

3. Cross-Promote Your SMS List in Email & Other Owned Channels

If you already have an engaged email list, website traffic, or app users, make sure they know about your SMS list. People who engage with your brand in one place are likely to want access in another, especially if SMS offers unique benefits they won’t get elsewhere.

How to Make It Work:

  • Add an SMS opt-in callout in your email footers and newsletters.
  • Use pop-ups or banners on your website to promote your SMS sign-up.
  • Mentioning SMS member sign-ups in customer service interactions grew their subscriber base to millions, with referrals contributing significantly to their growth.

Real Life: American City Business Journals leveraged its email newsletter to drive sign-ups for its SMS channel by highlighting the benefits of real-time news alerts and exclusive local business insights. By promoting the immediacy and convenience of text updates, it seamlessly converted engaged email readers into SMS subscribers.

4. Experiment with Giveaways and Contests

Giveaways and contests are proven ways to attract attention and attract new subscribers. By tying entry to SMS opt-ins, you can turn one-time interest into long-term engagement.

How to Make It Work:

  • Offer a prize that resonates with your ideal audience. The better the prize, the more likely they are to enter.
  • Keep the sign-up process simple. A quick text to enter works best.
  • Use contests to encourage sharing. Give bonus entries for referrals or social shares to expand reach.
  • Follow up. Keep new subscribers engaged even after the contest ends with a thoughtful welcome flow or exclusive offer.

Real Life: A Gen Alpha influencer recently sent out a survey to her followers via SMS marketing, offering a chance to win an Apple product just for participating. The giveaway drove high engagement and provided valuable feedback from her audience. Contests like this are a smart way to boost SMS member opt-ins while creating meaningful two-way interactions.

5. Use SMS Surveys and Polls to Spark Engagement

Polls and surveys are simple, interactive ways to keep subscribers engaged—and give them a reason to respond or share. They also give you valuable insights you can use to shape your content, offers, or future campaigns.

How to Make It Work:

  • Keep it quick. Ask 1–2 focused questions that are easy to answer via text.
  • Use the results. Share poll outcomes or personalized follow-ups to show their input matters.
  • Make it fun. Tie polls to trending topics, hot takes, or product preferences to encourage sharing.
