Omnisend SMS marketing is a solid, Shopify-friendly option if you want SMS inside the same automation tool you use for email and flows, with native Shopify integrations and built-in opt-in handling. If your priority is a fast on-site post-purchase survey tied to repeat purchase rate, Omnisend lets you collect phone opt-ins, send automated SMS, and report results inside the same campaigns dashboard, but it trades off enterprise SMS features, carrier-level optimizations, and dedicated deliverability support you get from a vendor focused only on SMS.

Does Omnisend support SMS marketing and will it work for a Shopify post-purchase survey?

Yes. Omnisend supports SMS as a channel you can add to campaigns and automations, provides a sending number option, and documents how to collect opt-ins and send campaigns from its dashboard, which maps directly to Shopify checkout and thank-you page opt-in flows. Use Omnisend to trigger a post-purchase SMS link to a short survey or a thank-you note that routes recipients to your Zigpoll survey. (support.omnisend.com)

How Omnisend’s SMS features fit a DTC Shopify merchant trying to raise repeat purchase rate

Omnisend bundles email plus SMS so you can run a post-purchase path without stitching separate vendors: collect phone numbers at checkout or via a thank-you page widget, then trigger an SMS 2 to 5 days after delivery asking one survey question and a promo for repeat purchase. Omnisend’s own benchmark material includes cases where SMS-driven activity materially increased orders, demonstrating the channel’s ability to move repeat behavior when it is tied to a measurement and segmentation loop.

List: 9 comparison points that matter for a post-purchase survey program aimed at raising repeat purchase rate. For each point, I compare Attentive, Omnisend, and Mailchimp and give a concrete recommendation you can implement this week.

1. Ease of shipping a post-purchase survey from Shopify

1. Attentive: strong enterprise on-site opt-in tooling and two-tap deep-link opt-ins; good if you will run high-volume, branded SMS surveys and want managed onboarding. Forrester interviews highlight fast onboarding and strategic account support. (tei.forrester.com)
2. Omnisend: plug-and-play with Shopify checkout, thank-you page and flows; you can add an SMS step to an existing post-purchase automation quickly. Good if your team runs email/SMS together and wants one UI. (support.omnisend.com)
3. Mailchimp: now offers SMS as an add-on; simple to get started if you already use Mailchimp, but feature parity with dedicated SMS platforms is mixed. Use when you want unified contact records in Mailchimp. (mailchimp.com)

Mistake I see: teams try to run a survey immediately on fulfillment and get low response rates and high opt-outs. Wait 2 to 5 days after delivery for the highest-quality responses.

2. Opt-in and compliance workflow

1. Attentive: explicit opt-in experiences and strong compliance posture; good for larger lists where mis-steps are costly. (tei.forrester.com)
2. Omnisend: built-in unsubscribe handling and compliance copy options; supports TCPA/regional unsubscribe flows. Good for merchants who prefer vendor-handled compliance templates. (support.omnisend.com)
3. Mailchimp: enforces opt-in confirmations and offers infrastructure for opt-outs; simpler for SMBs but read the sending-country limits first. (mailchimp.com)

Common mistake: not adding the required compliance text to SMS or truncating messages so the opt-out or legal text falls off the carrier segment.

3. Segmentation and automation power (how to use survey answers to change repeat purchase behavior)

1. Attentive: advanced segmentation and personalized journeys; best when you want dedicated SMS logic that personalizes at scale. (tei.forrester.com)
2. Omnisend: strong for multi-channel workflows; you can use survey responses to add contacts to an email + SMS sequence and trigger a 10 to 20 percent coupon for respondents who indicated interest. (omnisend.com)
3. Mailchimp: growing automation, good if you already manage customer segments here; its SMS tie-ins are more recent. (mailchimp.com)

Numbers to run: For a survey that drives repeat purchases, segment respondents into (A) “happy, would buy again” and (B) “neutral/detractors.” Send (A) a loyalty offer at day 7, send (B) a personalized recovery offer at day 3 plus a support touch.

4. Deliverability and scale

1. Attentive: invests in carrier relationships and managed delivery; that shows up for very large sends and complex MMS use cases. (tei.forrester.com)
2. Omnisend: reliable for thousands to tens of thousands of messages a month through toll-free and long-code options; documentation details segment length and carrier limits. (api-docs.omnisend.com)
3. Mailchimp: usable for SMB sends and credits-based purchasing, but for high-volume SMS you may hit limits or need extra approvals. (mailchimp.com)

Metric to monitor: opt-out rate after survey SMS; if opt-outs exceed 2 to 3 percent on follow-up surveys, cut cadence and review messaging.

5. Cost structure (opportunity cost and per-message fees)

1. Attentive: premium pricing, often bundled across channels; Forrester modeling shows significant platform costs but also quantifiable operational savings for large merchants. Budget accordingly. (tei.forrester.com)
2. Omnisend: priced within email platform tiers with SMS add-ons and per-message costs; straightforward for teams consolidating channels. (omnisend.com)
3. Mailchimp: credit model for SMS and add-on pricing; can be economical when starting small. (mailchimp.com)

Mistake: teams compare only per-message cost and forget to include engineering or tagging labor when estimating ROI.

6. Reporting and measuring repeat purchase lift

1. Attentive: enterprise reporting plus professional services can produce multi-channel attribution. (tei.forrester.com)
2. Omnisend: includes campaign reporting and examples where SMS activity increased orders by a material percentage; you can tie post-purchase survey responses to a repeat purchase flow and measure lift in your Shopify orders report. (omnisend.com)
3. Mailchimp: reports are improving; use UTM + Shopify order attribution for clean measurement. (mailchimp.com)

Anecdote: Omnisend’s benchmarks include a case where an SMS-driven flow produced a 23.8 percent increase in orders for a sample campaign, demonstrating lift that a well-instrumented post-purchase survey can help trigger and measure. (omnisend.com)

7. Integrations with Shopify-specific touchpoints

1. Attentive: built integrations for checkout and on-site capture, and can be tightly managed for enterprise checkout flows. (tei.forrester.com)
2. Omnisend: native Shopify app and direct mapping to checkout, thank-you page and customer profiles; good for Shopify merchants who want minimal engineering lift. (omnisend.com)
3. Mailchimp: connects to Shopify and can be used to store SMS consent in customer profiles; check plan requirements. (mailchimp.com)

Shop flows you’ll use: checkout opt-in checkbox, thank-you page widget to invite survey participation, and a post-purchase email/SMS flow that tags customers for repeat-offer sequences.

8. Best fit by merchant size and use case

1. Attentive: best for mid-market to enterprise with large SMS lists and need for managed deliverability. (tei.forrester.com)
2. Omnisend: best for SMB and mid-market Shopify merchants who want combined email + SMS automation and quick implementation. (omnisend.com)
3. Mailchimp: best for merchants already inside Mailchimp’s ecosystem who want to add SMS without adding a separate vendor. (mailchimp.com)

9. When not to pick Omnisend SMS

1. If you need carrier-level deliverability contracting or shortcodes for very high-volume MMS, choose Attentive. (tei.forrester.com)
2. If you already have a complex SMS program and want dedicated tooling for two-way conversational flows, consider dedicated SMS platforms.
3. If budget is the overriding constraint and you want the simplest credits model to test, Mailchimp can be the low-friction start. (mailchimp.com)

People also ask

Is Omnisend good for SMS marketing?

Yes, Omnisend supports SMS marketing well for Shopify merchants who want SMS inside the same automation platform they use for email, with native opt-in paths and automated flows you can use for post-purchase surveys. (support.omnisend.com)

How does Omnisend SMS compare to Attentive?

Omnisend combines email and SMS in one product and is quicker to ship for smaller teams, while Attentive is focused on SMS at enterprise scale, with deeper carrier relationships, managed onboarding, and specialized SMS features; choose based on list size, compliance risk, and required deliverability. (omnisend.com)

Can I use Omnisend SMS for post-purchase surveys on Shopify?

Yes, you can trigger an SMS from Omnisend after purchase or delivery pointing customers to a short survey, then feed responses back into your customer segments to trigger repeat-purchase offers. Make sure to handle opt-ins, time the message 2 to 5 days after delivery, and tag respondents in Shopify or your ESP. (support.omnisend.com)

Prioritization for a Shopify operator who needs impact this week

1. If you already use Omnisend for email: enable SMS, build a single-question post-purchase survey link, and trigger a follow-up sequence that grants a 10 percent coupon to positive responders. Expected work: <8 hours. (support.omnisend.com)
2. If you have 25k+ monthly SMS sends and need deliverability guarantees: evaluate Attentive and budget for professional onboarding, expect 4 to 12 weeks to fully migrate. (tei.forrester.com)
3. If you want the lowest-friction test without changing your ESP: add Mailchimp SMS credits and run a tiny A/B test on a 5,000-recipient cohort. (mailchimp.com)

Common mistakes I have seen teams make

• Sending the survey immediately on fulfillment, which reduces response quality and raises opt-outs.
• Forgetting to tag survey responders, then never using that data to trigger a repeat-offer flow.
• Comparing only per-message costs and ignoring engineering and reporting labor.
• Not validating opt-in source, then facing carrier filtering or legal risk.

Caveat SMS works best when you use it sparingly and with clear value to the customer; if your repeat purchase window is long or your products have high return rates, SMS survey-triggered coupons can increase churn or returns if not targeted.

How Zigpoll handles this for Shopify merchants

1. Trigger: Use Zigpoll’s post-purchase thank-you-page trigger, firing 48 to 72 hours after successful delivery confirmation (or use a 3-day email/SMS link sent from your flow if you prefer an outbound nudge). This ensures higher-quality responses and aligns the survey timing with product experience.
2. Question types and exact copy: a) Multiple choice + branching: “How satisfied are you with your recent order?” Options: Very satisfied; Somewhat satisfied; Not satisfied. If Not satisfied, show free text: “What went wrong?” b) Multiple choice: “Would you consider buying from us again?” Options: Yes, No, Maybe — then branch Yes to a loyalty code offer and No to a customer service outreach. c) CSAT star rating: “Rate the unboxing experience from 1 to 5.” These three capture NPS-style sentiment, friction reasons, and product experience insight while keeping the survey to one or two screens.
3. Where the data flows: Map Zigpoll responses into Shopify customer tags and metafields (for example tag customers as survey:promoter or survey:detractor), push responses to your Klaviyo segments and flows to trigger a repeat-purchase promo for promoters and a recovery flow for detractors, and send a summarized alert to a Slack channel or the Zigpoll dashboard for daily triage. This wiring lets you run a measurable loop: survey response → tagged cohort → automated offer → measure repeat purchase rate in Shopify orders.
