It's Thursday at 3:15 PM. A homeowner just submitted a lead form for a roof inspection. Your system sends two messages:
An email to their inbox. A text to their phone.
The email sits in their inbox. They'll see it later. Maybe. It gets buried under 47 other emails by tomorrow morning.
The text appears on their home screen. Ding. They read it in 42 seconds.
By 3:47 PM, they've already called the second contractor — the one who texted them back first.
This is the gap between email and SMS for lead follow-up. And it's costing you money every single week.
Quick summary: SMS has a 98% open rate vs. email's 21%. Texts get responses 45x faster than email. For service business leads — roofing, HVAC, plumbing, solar — SMS is not optional. It's the fastest path to "yes." But email isn't dead. The strategy is using both, at the right time, in the right order.
The Raw Numbers: Email vs SMS Response
Let's start with the data that matters.
Open rates: It's not even close
Email: 21% average open rate across all industries. B2B might hit 25-30% with solid subject lines. Service business leads? Closer to 15-18% because they're already comparing multiple quotes.
SMS: 98% open rate. Not 98% of people who read the content. 98% of people who see the message at all. The text appears on their lock screen. It gets read whether they want to or not.
This is asymmetric. Email depends on them remembering you exist and choosing to look. SMS is interruption marketing — and in the context of someone who just asked for a quote, interruption is exactly what you want.
Response time: Hours vs minutes
Email: If someone responds to your email at all, it takes an average of 24-48 hours. Many never respond. They just call the contractors who texted them.
SMS: Average response time is 90 seconds. Some studies show 45-120 seconds depending on industry and time of day.
Think about what this means for a home service lead. Someone fills out a form. They're thinking about their problem right now. They want a quote today. If you call or text them within 5 minutes, you're relevant. If you email them, they've already moved on by the time they see it.
Conversion rates: The practical difference
A Twilio study tracking over 1 million business-to-consumer interactions found:
- SMS follow-up: 45% conversion rate to next step (call, appointment booking, consultation)Email follow-up: 8-12% conversion rate to next stepEmail + SMS together: 68% conversion rate
That last number is the key insight. Email alone is weak. SMS alone is strong. Together, they're the dominant play.
Cost per message
Email: $0.005–$0.02 per message (essentially free at scale)
SMS: $0.01–$0.03 per message
SMS costs more. But when it's generating 5-10x more responses, the ROI math is simple. You spend an extra $0.02 and get 4x the conversion rate.
When to Use Email (And When Not To)
Email isn't dead. It's just not the first move for hot leads.
Use email for:
- Detailed information follow-up — After you've texted and they're interested, email can send comparisons, warranty details, financing options, photos of completed work.Nurturing cold leads — If someone doesn't respond to your first text, an email 24 hours later can keep you in their mental frame. It feels less pushy than a second text.Building authority — Weekly email tips and industry insights keep your contractors in the "top of mind" category for future referrals. SMS is too frequent for this.Post-appointment content — After they book, email can send prep instructions, what-to-expect guides, and payment information.
Don't use email for:
- First contact with a hot leadTime-sensitive offers or same-day appointment bookingWhen you need a response within hoursWhen you're competing with other contractors for attention
Email is a follow-up to the follow-up. It's the second touch that converts the already-interested into the committed.
The SMS-First Strategy
Here's what winning contractors are doing:
Minute 1: Lead comes in. SMS goes out immediately — 30-50 words, acknowledges their request, offers a specific time window for a callback or an instant booking link.
Minutes 5-15: If they don't respond to SMS, a phone call while you can.
Hours 2-4: If no answer, another SMS with a different angle — maybe a photo of similar work, or a social proof element.
Hours 4-24: Email with detailed comparison, pricing, warranty info, financing options. At this point, they've either committed or they're comparing. Email is for comparison and reassurance.
Day 2+: Email nurture sequence (weekly, infrequent) for re-engagement if needed.
The sequence is aggressive early (SMS + call within 15 minutes) and graceful later (email, infrequent follow-up). This mirrors how leads actually think about the decision.
The Best Hybrid Approach: SMS + Email
Here's what the data says about combining both:
- SMS for speed: 98% open, 90-second response time, highest conversion for hot leads.Email for depth: 21% open (but the 21% are engaged), delivers detailed info without seeming pushy, builds credibility.Sequence that works:
- T+2 min: SMS with specific ask ("Call us back by 2 PM for same-day quote")T+45 min: If no response, second SMST+2 hours: Email with detailed info and comparisonT+24 hours: Email follow-up with social proof or urgency elementT+3 days: Final email (if they haven't converted)
Example: SMS + Email Combo
What this looks like in practice:
- Send a short text immediately so the lead knows a real business saw the request.If they do not reply, send an email with more detail, comparison points, and a booking option.Use email to support the text, not to replace it.
First SMS
Send this immediately on lead submission:
Hi [Name] — got your request for [service]. We can schedule you as early as
[time tomorrow]. Reply YES to confirm or call (555) 123-4567. — [Company]Follow-up email
Send this 2 hours later if there is no response:
Subject: Your [Service] Quote Request
Hi [Name],
Thanks for requesting a [service] estimate. Based on what homeowners usually
run into with this issue, the next step is a quick call or inspection so we can
give you an accurate recommendation.
We can schedule you as early as tomorrow morning. Here are your options:
[Instant booking link]
[Phone number]
If it helps, we can also send examples of similar work we've done nearby.
Best,
[Name]The text gets attention. The email adds depth. That is the job split.
Why Contractors Still Use Only Email (And Why They Lose)
Most contractors still rely on email-first follow-up because:
- Cost: They don't realize the ROI difference between free email and cheap SMS.Inertia: Email lists and CRM systems have been around for years. SMS integration is newer.Volume assumption: "We get so many leads, at least some will respond to email."
Wrong. Your competitors are texting. If you email-only, you'll lose 80% of the hot leads to companies that text within 5 minutes.
Compliance: TCPA Rules for SMS
A quick note: SMS is regulated. You need:
- Prior express written consent (they agree to receive SMS from you)Clear opt-out mechanism on every messageTiming rules (no texts before 8 AM or after 9 PM in their timezone)
The good news: If someone fills out a quote form on your website, that's prior express written consent. You're legally clear to text them.
Just include an "Reply STOP to opt out" at the end of your messages, and you're compliant.
The Decision: Email or SMS?
For hot leads (submitted form in last 30 minutes): Text. 100 times out of 100, text.
For comparison shopping: Email, after you've texted.
For long-term relationship building: Email nurture sequences.
For re-engagement: SMS first, then email follow-up.
The contractors who are closing more leads aren't smarter or cheaper. They just texted first.
What to Do Monday Morning
- Check your lead follow-up system: Are you texting hot leads within 5 minutes? If not, that's costing you 45%+ in conversion rate right now.Set up the hybrid sequence: SMS first for hot leads, email second if there is no response after 2 hours, then email nurture for longer follow-up.Measure it: Track which leads you texted vs. emailed, and compare conversion rates. You'll see the gap immediately.Calculate the ROI: SMS costs a few cents more per lead. If it converts 5x better, the math is not close.
Email isn't going anywhere. But it's the second channel, not the first. Text first. Email follows. Together, they close deals.
