How do you set up an SMS auto-responder?
Use your CRM's built-in SMS feature or a standalone texting tool to send automatic replies. This post walks you through setup, what to automate, and what to skip. Most contractors can get this running in under an hour.
Check what your current tools already offer
Before you sign up for something new, look at what's in your back pocket. Most CRMs—Jobber, HubSpot, Housecall Pro—include basic SMS automation. Your phone carrier might too. If you're already paying for software, an auto-responder might be a checkbox you haven't turned on. Start there. If your CRM doesn't have it or the feature feels clunky, then evaluate dedicated texting platforms like Twilio, Plivo, or SimpleTexting. These let you set rules: if someone texts your number, they get Message A on weekdays and Message B after hours. No middle man, no forwarding. Real numbers from your contractors show this saves 3-4 hours a week on response time alone.
Set up the actual automation rules
The setup is straightforward. Pick your platform, connect your business phone number, and write your messages. Start with two: a weekday response and an after-hours response. Weekday example: 'Hi. We got your text. Someone from the team will reply within 2 hours.' After-hours example: 'We're not available right now. We'll get back to you first thing tomorrow morning.' That's it. Don't overthink it. Don't try to answer questions in the auto-reply. That's a trap—you'll spend forever tweaking the message, and it never covers every scenario. Your crew can handle the real conversation. The auto-responder just buys you time and shows the customer you're organized.
Automate messages for common crew situations
Once basic responses work, add routing. If a crew member sends a specific keyword—like 'APPROVAL'—you can auto-reply with a link to your estimate. If a customer texts 'WHERE'—location tracking—you can send a canned response with today's job address. If someone asks for a quote, route them to your booking page instead of making them wait. This works because the rules are simple and solve real friction. You're not trying to replace human judgment. You're just handling the obvious stuff so your phone isn't ringing 20 times a day with the same question. SimpleTexting and Twilio both support keyword triggers. Pick the 2-3 most common reasons people text you and automate those.
Keep it compliant and professional
Text message laws matter. The bigger platforms—Twilio, Plivo—handle compliance for you. They won't let you send unsolicited marketing texts. They enforce consent. Use the tool to respond to customers who reached out first. Don't spam numbers you haven't heard from. If you're using a CRM, the same rules apply. Keep tone professional but brief. Texts aren't emails. No long paragraphs. One or two sentences max. Customers expect text replies to be quick and human-sounding, not robotic. Test your auto-responder by texting your own number outside business hours. Read it the way a customer would. Refine. Then leave it alone for a few weeks. Once you see it working—fewer missed leads, crew less overwhelmed—you'll know it's worth the five minutes it took to set up.
Bottom line
Start with your CRM's built-in SMS if it exists. If not, pick a simple platform like Twilio or SimpleTexting and write two messages: one for business hours, one for after. That handles 80% of the value. Don't overautomated.
