In busy season you're on a roof, under a sink or with a customer when the phone rings. A lot of people won't leave a voicemail. They call the next business on the list.
Missed-call text-back is a simple fix. When you miss a call, the caller gets a text from your business number within a few seconds: something like “Sorry we missed you, this is Smith Heating. What can we help with?” Now they're talking to you, not your competitor.
How it works
- Someone calls your business number.
- Nobody picks up, or the call goes to voicemail.
- Your phone system or texting tool sends an automatic text to the caller.
- They reply by text, and the reply comes to you or your team.
Most business phone systems and lead tools offer it. The important part isn't the tool. It's the setup.
How to set it up so it actually saves leads
- Register the number for texting. If the texts go out automatically from a regular local number, carriers expect A2P 10DLC registration. Twilio, for example, blocks unregistered U.S. 10DLC messages. Ask your provider to confirm your number is registered, or your texts may never arrive.
- Write a short, human first text. Say who you are, that you missed the call and ask one question. “What do you need help with, and what town are you in?” works well.
- Tell them when you'll reply. If you won't answer for an hour, say so. Don't promise faster than you can do.
- Make replies reach a person. Replies should land on a phone someone checks, with a notification, not in a dashboard nobody opens.
- Skip texts to landlines and spam. Most tools let you limit text-back to mobile numbers or skip repeat callers. Turn that on if it's offered.
- Include a way to stop. Let people reply STOP to opt out, and honor it.
- Change the text for holidays and after hours. “We're closed until Monday; reply with what you need and we'll call first thing.”
- Test it. Call from a cell phone, let it ring out and check the text arrives. Reply and make sure the reply reaches you.
The checklist
- Number registered for business texting
- First text says who you are and asks one question
- Reply time stated honestly
- Replies notify a real person
- Landlines and repeat callers filtered if possible
- STOP opt-out works
- Holiday and after-hours text ready
- Tested from a cell phone
Where the website comes in
Text-back catches calls you miss. Your website decides how many calls you get in the first place, and it can offer a short quote form for people who would rather type. Before busy season, run our 15-point holiday test on your calls and forms too. If you want a site built around getting more of those calls, tell us about your business.
Questions
What is missed-call text-back?
When a call to your business number goes unanswered, the phone system sends the caller a text automatically, so they hear from you right away instead of hitting voicemail and moving on.
Can I do it with my regular business number?
Often, yes, if your phone provider or a texting tool supports it. Some set it up on your current number; others need a new number or forwarding.
Do I need to register to send business texts?
If texts go out automatically from a regular 10-digit number to U.S. phones, carriers expect A2P 10DLC registration, and unregistered messages can be blocked. Ask your provider whether your number is registered.
