Email vs SMS Review Requests

Open Rates Tell the Story

SMS messages enjoy a ninety-eight percent open rate compared to roughly twenty percent for email. That gap alone makes text the stronger channel for time-sensitive review requests. However open rate is not the only metric that matters. Email allows richer formatting, embedded links, and brand imagery that can reinforce trust before the customer clicks through to leave their review.

Conversion Rate Differences

Despite lower open rates email review requests often convert at similar rates to SMS because recipients who open email are already engaged. SMS wins on speed with most reviews arriving within thirty minutes of delivery. Email reviews trickle in over two to three days. ReviewGuard tracks conversion by channel so you can see exactly which method performs best for your specific audience segment.

Cost and Compliance Considerations

SMS carries per-message costs that add up quickly for high-volume businesses. Email is essentially free at scale. Both channels require opt-in consent but SMS regulations under TCPA are stricter with fines reaching fifteen hundred dollars per unsolicited text. ReviewGuard handles compliance automatically by verifying consent status before sending any message through either channel.

The Best Approach Uses Both

Top-performing businesses use SMS as the primary request and email as the follow-up reminder. This dual-channel strategy captures quick responders via text and catches the rest through email. ReviewGuard lets you configure this sequence in one automation rule. Businesses using both channels typically see a thirty to forty percent lift in total review volume compared to single-channel campaigns.
