SMS vs Email for Review Requests: Which Gets More Google Reviews?

Reviewpull Team

You have decided to start collecting Google reviews systematically. Good. Now you face a practical question: should you send review requests via SMS or email?

Both channels work. But they work differently, they cost differently, and they perform differently depending on your business type. Here is the complete comparison to help you choose the right approach.

The Numbers: SMS vs Email at a Glance

| Metric | SMS | Email | |---|---|---| | Open rate | 98% | 20-25% | | Click-through rate | 19-36% | 2-5% | | Average response time | 90 seconds | 6-8 hours | | Review completion rate | 12-20% | 3-8% | | Cost per message | $0.01-0.05 | Free-$0.003 | | Opt-in required | Yes (TCPA) | Yes (CAN-SPAM) | | Unsubscribe rate | 1-2% | 0.5-1% | | Character limit | 160 (SMS) / 1600 (MMS) | Unlimited |

The headline number is clear: SMS gets dramatically higher engagement. A 98% open rate versus 20-25% is not a marginal difference — it is a completely different ballgame. But open rates alone do not tell the full story.

When SMS Works Best

SMS is the superior channel when:

The service just happened. For businesses where the customer was physically present — restaurants, dental practices, salons, auto repair shops — an SMS sent within hours of the visit feels natural. The customer expects communication via text in these contexts.

Your audience skews mobile-first. Younger demographics (under 45) respond to SMS at significantly higher rates than email. If your customer base is primarily millennials or Gen Z, SMS is the clear winner.

You need speed. If review velocity matters to you (and it should — Google rewards businesses that receive reviews consistently), SMS delivers reviews faster. Most SMS review requests that convert do so within 5 minutes of being received.

The ask is simple. SMS works because it is frictionless. A short message with a direct link gets tapped and completed in under two minutes. Do not try to put complex messaging in a text.

Sample SMS Review Request

Hi [Name], thanks for choosing [Business Name]! We would love your feedback. Could you leave us a quick Google review? [review link] — Thank you!

When Email Works Best

Email is the better choice when:

You need to provide context. For professional services — law firms, accounting practices, consulting firms — a review request benefits from more context. Email gives you room to remind the customer what you accomplished for them.

Your audience is B2B. Business decision-makers engage with email more consistently than SMS for professional interactions. A text message from your accountant feels strange; an email feels appropriate.

You want to include branding. Email allows logos, formatting, and a polished visual presentation that reinforces your brand. SMS is plain text.

Compliance is a concern. While both channels have regulations, email compliance (CAN-SPAM) is generally simpler to manage than SMS compliance (TCPA). Email does not require explicit prior consent the same way SMS does, though you should always follow best practices.

You are sending follow-ups. If someone did not respond to your first request, a follow-up email feels less intrusive than a follow-up text message.

Sample Email Review Request

Subject line: How did we do, [Name]?

Hi [Name],

Thank you for trusting [Business Name] with your [service type]. We hope everything met your expectations.

If you have a moment, we would truly appreciate a Google review. It only takes about 60 seconds and helps other customers find us.

The Hybrid Approach: Using Both

The most effective strategy for most businesses is a hybrid approach:

  1. Primary request via SMS (sent 1-4 hours after service)
  2. Follow-up via email (sent 3-5 days later to non-responders)

This captures the high-engagement SMS audience immediately and catches the email-preferred audience on the follow-up. In our data, businesses using a hybrid approach see 40-60% higher total review collection compared to using either channel alone.

The key is to avoid doubling up on the same day. If you send an SMS and an email on the same day, it feels aggressive and increases opt-out rates.

Compliance Essentials

SMS Compliance (TCPA)

The Telephone Consumer Protection Act requires:

  • Express written consent before sending marketing texts (review requests count)
  • Clear opt-out mechanism in every message (e.g., "Reply STOP to unsubscribe")
  • Identification of your business in the message
  • No messages before 8 AM or after 9 PM in the recipient's time zone

Violations can carry penalties of $500-$1,500 per message. This is not something to take lightly. Collect consent at the point of service — a simple checkbox on your intake form or a verbal confirmation that you document.

Email Compliance (CAN-SPAM)

CAN-SPAM requires:

  • Accurate "From" and "Subject" lines
  • Physical mailing address included
  • Clear unsubscribe mechanism
  • Honor opt-outs within 10 business days

Email compliance is less burdensome, but ignoring it can result in penalties up to $46,517 per violation.
