Not All Texts Are Spammy: The Power of Opt-In Messaging with Subtext

Written by Subtext | Jun 30, 2025

If you’ve ever been bombarded by political campaign texts, fundraising requests, or random one-liners from numbers you don’t recognize, you’ve probably thought:

“Isn’t texting just... spam now?”

We hear this a lot - especially from newsrooms, brands, artists and organizations who care deeply about their audience. If you’re asking that question, it likely means you want to do SMS the right way. And that’s exactly where Subtext comes in.

Let’s unpack why SMS can feel spammy, how Subtext flips that experience into being one of the most trusted, personal ways to connect with your audience, and why it’s all backed by an increasingly important framework called 10DLC.

The Problem: Texting Has a Trust Problem

Text messaging used to be reserved for people you knew. So when a stranger or a political campaign suddenly pops up in your messages with something you never asked for, it feels invasive and rightly so. These unsolicited messages are usually:

  • Sent without your explicit consent
  • Generic or automated
  • Disruptive rather than useful

In short: spammy. And for many, these are the only examples of SMS they’ve encountered. Just a cold, 6-digit short code and a one-way message. That’s not a conversation. That’s a disruption.
But here’s the good news: not all SMS is created equal.


The Subtext Difference: Opted In. Wanted. Trusted.

Subtext is opt-in only. That means no scraping numbers. No surprise blasts. Just real, two-way connections with people who chose to hear from you.

Your subscribers:

  1. Signed up for your texts
  2. Know who you are
  3. Want to hear from you

Your subscribers aren’t just names on a list. They’ve said, “Yes, I want to hear more from you.” That one decision - to invite, not intrude - makes all the difference.

Subtext messages don’t interrupt. They’re invited.


Enter: 10DLC - The Framework That Keeps Messaging Clean

To help enforce that kind of trusted messaging ecosystem, the mobile industry introduced 10DLC (which stands for 10-Digit Long Code). It’s a carrier-approved registration system where businesses register their brand and campaign traffic for approval, allowing them to send high-volume text messages responsibly and transparently. 

Here’s why 10DLC matters for you and your subscribers:

Verified sender identity: With 10DLC, all messaging campaigns must be registered and approved. No more anonymous mass texts.

Spam protection: Carriers use 10DLC registration to identify and block bad actors, so your messages don’t get lumped in with spam.

Higher deliverability: Since Subtext is a verified 10DLC provider, your messages are more likely to land successfully and quickly in inboxes.

Accountability: Every message sent through 10DLC is tied to a campaign with declared use cases, which means better transparency and trust.

Subtext handles all of this behind the scenes. You don’t need to navigate 10DLC compliance alone. Our SMS experts offer white-glove registration, so your messaging is secure, ethical, and industry-approved from day one.

What this means for you:

When you use Subtext, you’re not just sending messages, you’re building a community based on consent and connection.

That means:

  • You’re not interrupting strangers, you’re texting your biggest fans
  • You’re not spamming, you’re sharing exclusive content with people who asked for it
  • You’re not risking trust, you’re reinforcing it

And thanks to 10DLC, your messages aren’t just wanted, they’re trusted and protected, too.

3 Ways to Make Your Messages Feel Personal, Not Promotional

Worried your texts might still come off a little cold or corporate? Here are a few simple ways to keep things warm, conversational, and not spammy:

1. Keep It Casual, Keep It Real
 Write like you talk. A quick text can feel like a private DM if it sounds like you. Don’t overthink it, just be yourself.
2. Introduce Yourself (Every Time)
 Start your messages with “Hey, it’s [Your Name]” or sign off with your name. That human touch makes a big difference.
3. Use a Custom Contact Card
 Subtext makes it easy for subscribers to save your number with a custom contact card—complete with your name, photo, and brand. That way, your texts always show up as you, not as a mystery number. (And bonus: no one ever has to ask “who’s this?” again.)
