Call, text or email? Customer contact preferences

What the data says about channel preferences

Ask a room of contractors whether customers prefer calls or texts and you will get a confident answer in both directions. The data says both camps are partly right. In Pew Research Center's study of text messaging, 31% of people who text said they preferred texts to talking on the phone, 53% preferred a voice call and 14% said it depended on the situation^[1]. Among heavy texters, who exchanged more than 50 messages a day, 55% preferred a text^[1].

That study is from 2011, and habits have shifted since. Phones are nearly universal now: Pew reports that 98% of US adults own a cellphone and 91% own a smartphone, and 16% rely on a smartphone as their only home internet^[4]. What has not changed is that people differ. A retired homeowner may want a call; a nurse on shift may only read texts at breaks; a landlord may want everything by email.

Why calling first often fails

Calling is still the best channel for complex conversations, but it is a poor first touch from an unrecognized number. Pew found that eight in ten Americans say they do not generally answer cellphone calls from unknown numbers, and only 19% say they generally answer them^[2]. Spam calls trained people to ignore them. The National Do Not Call Registry held 259 million active registrations in 2025^[5], a measure of how much people want control over who calls them.

• Use one consistent outbound caller ID, ideally the same number customers called to book.
• Register that number with your carriers' caller identification programs where available, so it shows your business name.
• Text before calling when the call is not urgent: 'Hi, it's Brightline about your estimate. Is now a good time for a quick call?'
• Leave a short voicemail with your company name and a reason if you do call and miss them.

Timing matters too. BLS reports that 81% of employed Americans worked on an average weekday in 2025, compared with 30% on an average weekend day^[6]. A call at 10 a.m. on a Tuesday reaches many customers at work. Store the best time to reach each customer and respect it.

What to ask and store for every customer

Ask once, at booking, and confirm at the first visit if anything has changed. Then make sure your software uses the field. A preference that is recorded but ignored is worse than none, because the customer told you and you did not listen.

Matching the channel to the message

Preference sets the default, but some messages have a natural channel. Use this as a starting point and override it with the customer's stated preference where it makes sense.

• Booking confirmations and reminders: text, with email as a backup. They need to be read, not discussed.
• On-the-way and running-late updates: text. Short, time-sensitive and easy to read while busy.
• Diagnosis findings and repair options: in person or by phone, followed by a written summary. Customers need to ask questions.
• Estimates for larger jobs: email or a link by text, followed by a call a few days later.
• Invoices and receipts: email or text link, whichever the customer chose.
• Complaints and problems: always a call from a person, then a written confirmation.
• Maintenance reminders and offers: the customer's preferred channel, and only with the right consent.

Consent and the rules that apply

Service messages a customer expects, such as a confirmation for a visit they booked, are treated differently from marketing. The Telephone Consumer Protection Act and FCC rules restrict automated calls and texts, especially marketing, without the right consent. In 2024 the FCC ruled unanimously that calls made with AI-generated voices are 'artificial' under the TCPA^[3], so automated voice calls to customers need the same care as prerecorded ones.

• Record consent for service texts at booking, with date and method.
• Get separate, clear consent before sending marketing texts.
• Honor STOP replies and opt-outs immediately across all your tools.
• Register your texting numbers for business messaging with your provider; see post-job follow-up calls and texts for message examples.
• Ask your attorney or provider about state rules that add to the federal ones.

This is general information, not legal advice. Rules on calls and texts change, and penalties can add up quickly per message.

Example: one customer, one preference, every touch

Example: a fictional homeowner books a furnace tune-up and says she prefers texts, works hospital shifts and cannot take calls before 3 p.m. The office records text, mobile, after 3 p.m., English, homeowner, service text consent yes, marketing consent no.

1. The confirmation and reminder go by text.
2. The technician texts when on the way instead of calling.
3. The technician finds a cracked part and, because options need discussion, the office texts at 3:15 p.m.: 'Is now a good time for a five-minute call about your furnace?' She replies yes.
4. The estimate follows by text link, and the follow-up is a text two days later.
5. She receives no marketing texts, because she did not consent to them.

Nothing here is complicated, but each step respects what she said. That is what customers remember, and it is why the same homeowner calls you back next year instead of searching again.

Language, accessibility and who is really the customer

Channel is only one part of a preference. Two other details cause frequent problems in home services: language and the difference between the person at the home and the person who pays.

• Language: if a customer prefers Spanish or another language, record it and route calls to a team member who speaks it, or use templates in that language. See handling Spanish-speaking callers for scripts and staffing options.
• Hearing or speech difficulties: some customers rely on text or email entirely. Make sure technicians know not to call those customers on arrival.
• Older customers: some prefer a call from a person and a printed estimate left behind. Record it rather than assuming.
• Rentals: the tenant usually needs arrival updates; the owner or property manager needs estimates, approvals and invoices. Store both contacts with their roles.
• Family members: an adult child may manage a parent's home. Note who may approve work and receive invoices.

Getting these details right avoids a common failure: the right message sent to the wrong person, or the right person reached in a way they cannot use. Review a sample of customer records each quarter to check that these fields are filled in and still accurate, and fix the booking script if the same field keeps coming back empty.

Common mistakes

• Asking for a preference and then sending everything by the default channel anyway.
• Texting the landline the customer gave for the booking.
• Contacting a tenant about payment instead of the owner or property manager.
• Calling repeatedly from different numbers until someone answers.
• Treating marketing consent as automatic because the customer booked a service.
• Not recording opt-outs in every system, so one tool keeps sending.

Stored preferences also help in harder moments. When a relationship becomes difficult, as covered in when and how to fire a difficult customer, a clean record of how and when you communicated is part of handling it fairly.
