Text vs. Call vs. Email: Which Follow-Up Gets the Best Response Rate?

Text has a 98% open rate. Email sits at 20%. Phone calls get answered about 50% of the time.

If you’re picking just one channel for follow-up, text wins on pure visibility. But the contractors closing the most leads aren’t picking one channel — they’re using all three in a specific order.

Hatch analyzed 132,000+ HVAC speed-to-lead campaigns in December 2024 and the results were definitive. Multi-channel sequences achieved a 90% response rate at the top end. Single-message campaigns managed just 8%. The gap between best and worst wasn’t the channel — it was the cadence.

Text: highest visibility, lowest friction

Text messages get read. Gartner’s mobile engagement data shows that 97% of texts are read within 3 minutes of delivery. No other channel comes close to that immediacy.

For home service follow-up, texts work best when they’re short, specific, and end with a question. The sweet spot is 160-220 characters — long enough to provide context, short enough to feel personal.

Good text: “Hi Sarah, this is Mike from ABC Plumbing. Got your request about the water heater. I have a tech available tomorrow 8-10am. Does that work?”

Bad text: “Thank you for contacting ABC Plumbing! We appreciate your interest in our services. One of our qualified technicians would be happy to assist you with your plumbing needs. Please call us at your earliest convenience to schedule an appointment.”

The second reads like a marketing blast. The first reads like a person. Homeowners respond to people.

A plumber on r/sweatystartup shared that switching from email-first to text-first follow-up increased his response rate from 22% to 61% overnight. Same leads, same offer, different channel. He sends a text within 2 minutes of every web form submission using automated workflows in his CRM.

When text falls short

Text is great for initial contact and quick confirmations. It’s weak for complex discussions. Detailed estimates, financing explanations, and scope-of-work conversations don’t work in 160 characters.

Text also lacks emotional connection. A homeowner with a flooded basement wants to hear a calm, confident human voice — not read a text bubble.

Phone calls: highest conversion, hardest to connect

When you actually reach someone by phone, the conversion rate is significantly higher than text or email. Power Selling Pros data shows that live phone conversations convert 3-4x higher than text exchanges for booking appointments.

The problem is reaching them. Call answer rates for unknown numbers hover around 50% and drop lower for younger homeowners. Robocall fatigue means many people send unfamiliar numbers straight to voicemail.

Voicemail converts at a fraction of live calls. Only 15-20% of voicemails result in a callback, according to InsideSales.com data.

Timing matters enormously. Calling within 5 minutes of a lead submission produces a contact rate of 80%+ versus 30% after an hour. The homeowner just filled out your form and they’re expecting a response. Wait too long and they’ve moved on.

Tommy Mello of A1 Garage Door Service has discussed on The Home Service Expert podcast how his team treats every inbound lead as a race. The first call happens within minutes. If it goes to voicemail, a text goes out immediately. The combination of a missed call notification plus a text creates urgency that neither alone achieves.

When to call vs. text first

Call first on emergency requests — water leaks, AC failures, electrical problems. The homeowner is in crisis mode and wants to talk to someone now.

Text first on non-emergency inquiries — quotes, seasonal maintenance, planned renovations. These homeowners are researching and prefer to engage on their terms without pressure.

Email: lowest open rate, highest information density

Email open rates for home service companies run 18-22% according to Mailchimp’s 2025 industry benchmarks. Compared to text, that looks terrible. But email serves a different purpose.

Email works best for sending detailed estimates, before/after photos, financing options, and warranty information. It creates a written record the homeowner can reference later and share with a spouse or partner who co-makes the decision.

One HVAC company on ContractorTalk described using email exclusively for estimate follow-up with attached PDFs, customer testimonials, and financing calculators. Their email open rate was only 24%, but among homeowners who opened the estimate email, 35% eventually booked — a higher conversion rate than their text-only follow-up.

Email also wins for long-term nurture. A homeowner who got a $15,000 roof estimate in March might not be ready until September. Monthly email touchpoints keep you top of mind without the intrusiveness of repeated texts or calls.

The optimal multi-channel sequence

The data from Hatch’s 132,000+ campaign analysis points to a clear winning formula: 5 texts, 2 emails, over 5 days.

Here’s what that looks like adapted for a home service contractor:

Within 5 minutes: Text confirming receipt and proposing a time. “Hi [Name], got your request about [service]. I have availability tomorrow morning. Does 8-10am work?”

Within 30 minutes: Phone call. If no answer, leave a voicemail referencing the text.

Day 1 (evening): Email with your company introduction, relevant reviews, and a link to schedule online.

Day 2: Text follow-up. “Just checking in on [service]. Still have availability this week if you’d like to get it scheduled.”

Day 3: Phone call attempt #2. Different time of day than the first.

Day 5: Email with a specific offer or financing mention. “Wanted to make sure you saw our financing options — as low as $X/month for [service].”

Day 7: Final text. “Hi [Name], following up one last time on [service]. If you’d like to schedule, just reply here. If timing isn’t right, no worries — we’re here when you’re ready.”

This sequence hits 7 touchpoints across 3 channels in 7 days. Each touchpoint adds information rather than repeating the same ask.

What the data says about multi-channel

Contractors using structured multi-channel follow-up convert 25-35% more leads than those using a single channel, according to ServiceTitan’s 2024 conversion benchmarks.

The reason is coverage. A homeowner who ignores texts might open emails. Someone who never answers calls responds to texts within seconds. By using all three channels, you reach people where they actually engage.

An electrical contractor on r/sweatystartup shared his conversion data across channels: text-only follow-up converted 18% of leads, phone-only converted 12%, email-only converted 8%. His multi-channel sequence combining all three converted 31%. Same leads, same offer. Triple the conversion rate of any single channel.

Automation makes it sustainable

Running a 7-touchpoint sequence on every lead manually is impossible at scale. A company generating 100 leads per month would need to send 700+ messages — no one has time for that.

CRMs like ServiceTitan, Housecall Pro, and GoHighLevel can automate the entire sequence. Set it up once, and every new lead enters the flow automatically. The only manual step is the phone call, which your CSR handles.

The cost of automation platforms runs $100-$300/month. The return on automating follow-up for even 5 additional bookings per month at a $1,500 average ticket is $7,500/month. That’s a 25-75x return on the software cost.

The channel mix by lead type

Lead Type	Best First Touch	Follow-Up Sequence
Emergency service	Phone call	Text if no answer, call again in 15 min
Website form fill	Text within 5 min	Call within 30 min, email Day 1
Unsold estimate	Text Day 1	Email Day 2 with estimate, call Day 3
Past customer reactivation	Email with offer	Text Day 3, call Day 7
Referral	Phone call	Text confirmation, email with info

Match the channel to the situation. Emergencies need a voice. Research-phase leads need low-friction text. Complex decisions need email detail.

The right question isn’t which channel works best. The right question is which sequence of channels converts the most leads at the lowest cost. The answer, consistently, is all of them working together.
