ESL programs lose students to competitors and scheduling conflicts every month—and most owners never reach out to re-engage them. SMS marketing is the fastest, cheapest way to remind past and current students why your instruction matters before they enroll elsewhere. With open rates above 95%, text messages reach students where email never does.
Why SMS Works for ESL Programs
Your students live on their phones. Whether they're juggling work and family or managing time zones across continents, SMS cuts through the noise of email inboxes and social media feeds. A well-timed text about a new beginner conversation class or a reminder that registration closes Friday gets immediate attention—texts are read within three minutes on average, compared to hours or days for email.
For ESL instruction specifically, SMS eliminates language barriers that can slow enrollment. A short, clear message ("New TOEFL prep class starts Monday. Enroll here: [link]") requires less reading comprehension than a detailed email, making it accessible to students at different proficiency levels.
Building Your SMS List
Start with students you already have. Add an opt-in form to your website, social media profiles, and enrollment pages. Offer a small incentive—a 10% discount on the next course, a free conversation hour, or access to grammar tips—in exchange for their number. Expect a 15–25% opt-in rate if you ask at signup or post-enrollment.
Ask former students to re-engage. If you have contact records, send a one-time invitation asking if they'd like course updates and special offers via text. Frame it honestly: "We're sending class announcements and exclusive discounts to alumni. Interested?" Many will respond, especially if they enjoyed their experience.
Don't buy lists. Purchased phone numbers lead to unsubscribe rates above 40% and damage your sender reputation. Build organically instead.
Campaigns That Retain ESL Students
Course reminders and starts Send a text three days before a class begins: "Your Intermediate English course starts Monday at 7pm. Reply READY to confirm attendance." This catches students who registered but forgot and gives you a response metric.
Milestone celebrations "You've completed 10 lessons in your American Accent course! You're ready for the conversation module. Here's your access link: [link]" Students feel progress and stay enrolled longer.
Urgency-driven promotions "Early-bird pricing ends Friday for our Summer Conversation Intensive. Secure your spot: [link]" Limited-time offers drive immediate action. Plan these campaigns 10–14 days before a course launch.
Re-engagement for dormant students If someone hasn't logged in for 60 days, send: "We miss you! Your subscription is paused. Ready to resume? Reply YES or message us." This brings back 8–12% of inactive learners per campaign.
Level-up notifications "Your instructor marked you ready for the next level. New class available here: [link]" Progression signals motivate continuation.
Frequency and Timing
Send 1–2 messages per week maximum. More than that triggers opt-outs. Space out promotional messages (course launches, discounts) with informational ones (tips, reminders, celebrations).
Timing matters. For working professionals studying evenings: send messages at 6–7pm weekdays. For students abroad, account for time zones—software like Twilio or MessageBird handles scheduled sends across regions.
Tools and Costs
Twilio: Pay $0.0079 per SMS sent in the US, no monthly fee. Scales with volume.
Klaviyo SMS: Starts at $0 for under 500 contacts; $25/month for up to 10,000. Integrates with email and works well for bundled campaigns.
Constant Contact: SMS add-on is $20/month with 100 texts; $50/month for 500 texts.
For an ESL program with 100–300 active students, budget $20–75 monthly. Compare that to paid ads ($300–1,000+ monthly) or email-only strategies that get ignored.
When you're ready to grow visibility and attract new students, listing your services on Mercoly helps you get found by serious learners, win qualified leads, and scale your student base efficiently.
Frequently Asked Questions
Q: What happens if a student replies to my SMS? A: Most SMS platforms send replies to an inbox you can access; you'll see the student's response and can reply directly or trigger an automated response, like sending enrollment instructions or scheduling a call.
Q: Should I include links in every text? A: No. Mix messages—some with links (enrollment, access), others without (reminders, encouragement). Too many links per week feel salesy and increase opt-outs.
Q: How do I comply with SMS laws like TCPA? A: Always get explicit opt-in consent (students must text back or check a box), honor unsubscribe requests immediately, and avoid sending before 8am or after 9pm their local time. Platforms like Twilio handle legal compliance automatically.
