Bulk SMS broadcasts for seasonal promos, announcements, and re-engagement.
Last updated April 4, 2026
Most small businesses rely on email for marketing, but email open rates average just 20% and click-through rates hover around 2.5%, according to Constant Contact's 2026 benchmark data. That means 80% of marketing emails are never opened. SMS flips those numbers. According to Gartner, text messages have a 98% open rate and an 18-35% click-through rate. Research from Omnisend shows that automated SMS messages generate five times more revenue per send than email broadcast campaigns. The U.S. SMS marketing market is projected to reach $12.6 billion by 2025, growing at 20.3% annually, per industry research cited by TxtImpact. Service businesses that send a text about a seasonal special, a cancellation opening, or a limited-time discount reach nearly every recipient. AI Sidekick lets you build and send targeted SMS campaigns to your customer list, with AI handling the message creation, scheduling, and response management.
Consider a dental office running a teeth-whitening promotion in January. An email blast to 500 patients yields 100 opens and maybe 3 clicks. The same promotion sent by text reaches 490 of those patients, and research from Sakari shows SMS conversion rates average 21-30% for service businesses. That is the difference between 3 responses and 100+ responses from the same customer list.
According to Project Broadcast, 84% of consumers have opted in to receive SMS messages from at least one business as of 2025. Customers are not just tolerating business texts. According to Optimonk, 72% of consumers have made a purchase after receiving a brand text message. SMS campaigns convert because the message lands in the same inbox as texts from friends and family, not a cluttered email promotions tab.
SMS campaigns cost more per message than email, but the engagement gap more than compensates. The math favors text for service businesses with customer lists under 5,000 contacts.

According to Omnisend, automated SMS messages generate $21 to $41 return for every $1 spent, with seasonal campaigns reaching up to $71 per dollar during peak periods. For a med spa sending a 20%-off Botox promotion to 300 opted-in patients, even a conservative 10% redemption rate at $300 per treatment means $9,000 in revenue from a single text campaign.
AI Sidekick handles campaign creation, audience selection, scheduling, and reply management. You choose what to promote and when. AI Sidekick handles the rest.
| Step | What happens | |
|---|---|---|
| 1 | Choose your audience | Select from your contact list by tags, service history, or custom segments. Target past customers who have not booked in 90 days, customers in a specific service area, or patients due for a recurring appointment. |
| 2 | Create the message | Write a brief text message with your offer, or let AI Sidekick draft one based on the promotion details. Messages stay under 160 characters for optimal delivery. Each message includes your business name and a clear call to action. |
| 3 | Schedule or send | Send the campaign immediately or schedule for a specific date and time. Research from SimpleTexting shows that Tuesday through Thursday between 10 AM and 2 PM produces the highest engagement for service business campaigns. |
| 4 | AI handles replies | When recipients reply with questions about the promotion, AI Sidekick responds automatically with details about pricing, availability, and booking. Every reply becomes a two-way conversation managed by AI. |
| 5 | Track results | View delivery rate, open rate, response rate, and booked appointments from each campaign in one dashboard. AI Sidekick attributes revenue to specific campaigns so you see exact return on each text blast. |
Here is a step-by-step walkthrough of a seasonal promotion campaign for a residential HVAC company sending a spring AC tune-up offer to existing customers.
Four capabilities turn a simple text blast into a revenue-generating campaign with built-in conversation handling.
Target campaigns by service history, recency, location, or custom tags. According to Attentive, segmented SMS campaigns boost open rates by 44% compared to unsegmented blasts. AI Sidekick lets you build segments like "customers who booked AC service last summer" or "patients overdue for a cleaning."
When campaign recipients reply with questions, AI Sidekick responds automatically using your configured service and pricing information. Every reply becomes a two-way conversation. According to SimpleTexting, 50% of businesses say the ability to have two-way conversations is the biggest advantage of SMS marketing.
Schedule campaigns for optimal send times. AI Sidekick sends texts during business-appropriate hours, respecting time zones and TCPA quiet hours. Research from SimpleTexting shows midweek messages between 10 AM and 2 PM produce the highest engagement for service businesses.
Track delivery rate, click-through rate, response rate, and booked appointments per campaign. AI Sidekick attributes revenue to each campaign so you see exact ROI. Compare performance across campaigns to identify what promotions and messaging drive the most bookings.
