Stop sending to
invalid emails
EmailSignal automatically cleans your Shopify or Wix customer list — detecting bounces, spam traps, and disposable addresses so every campaign lands in the inbox.
Free plan available · No credit card required · Works with any Shopify or Wix store
Everything your store needs for clean email marketing
EmailSignal plugs directly into Shopify or Wix — zero code, zero friction, instant results.
One-click setup
Connect to your Shopify or Wix store in seconds. No developer, no code, no configuration headaches.
Cross-checked accuracy
Every address is checked across multiple independent verification engines and the results are cross-checked against each other — boosting accuracy by about 20% over single-provider checks.
Tag-based segmentation
Results flow directly into your store's customer tags (Shopify) or labels (Wix) — including a Confident tag for the ~99% most certain deliverable results — so you can filter, segment, and act immediately.
Spam-trap detection
Catch honeypots, role-based addresses, and disposable domains before they damage your sender score.
Always-on coverage
The app runs continuously — every new and updated customer email is verified the moment it arrives, with zero manual action needed.
AI-powered list insights
An AI-generated list-health report explains what your verification results mean in plain language — how healthy your list is, how it is trending, and what to do next to improve deliverability. Included on every plan.
Automatic marketing opt-out
Automatically unsubscribe undeliverable or risky addresses from your store's email marketing list, protecting your sender reputation without manual list cleaning.
Works with your email tools
Verification tags and labels sync with Klaviyo, Mailchimp, Omnisend, and any other platform that reads your store's customer data.
Payments secured by the platform
All billing is handled directly by Shopify or Wix — the same platforms trusted by millions of merchants. We never touch your payment details.
Up and running in three steps
No developer resources needed. The whole setup takes under five minutes.

Built for real Shopify and Wix workflows
Whether you send weekly newsletters or triggered automations, clean email data makes everything perform better.
Pre-launch email campaigns
Scrub your list before every major send. Fewer bounces means higher inbox placement rates and a healthier domain reputation.

Migrating customers from another platform? Verify all imported addresses before your first campaign goes out.
Continuous new customer coverage
EmailSignal is always running. Every new customer who signs up gets their email verified automatically — no manual action needed.
Works with any email platform
Tag or label invalid emails in your Shopify or Wix store, then exclude them in Klaviyo, Mailchimp, Omnisend, or any other tool you already use.
Cross-checked accuracy, built right in
No external accounts, no API keys. EmailSignal checks every address across multiple independent verification engines and cross-checks the results against each other — boosting accuracy by about 20% over single-provider checks. Addresses confirmed by multiple signals get our highest-confidence Confident tag, accurate roughly 99% of the time.
Frequently asked questions
- Is EmailSignal the same product as EmailVerify?
- Yes. EmailVerify has been renamed to EmailSignal — same app, same team, same pricing. Your existing setup keeps working: on Shopify your current "emailverify:*" tags stay in place and are still maintained alongside the new "emailsignal:*" tags, and on Wix your existing "EmailVerify: …" labels are kept next to the new "EmailSignal: …" labels, so any segment, filter or automation you built keeps working.
- How does EmailSignal connect to my store?
- EmailSignal connects through the official Shopify Partner API or the Wix App Market API, depending on where you install it. You install the app from the Shopify App Store or the Wix App Market and grant read/write access to customers. No manual setup is required.
- How does EmailSignal reach such high accuracy?
- EmailSignal doesn't rely on a single verification provider. Every address is checked across multiple independent verification engines, and the results are cross-checked against each other — boosting accuracy by about 20% over single-provider checks. Addresses confirmed by multiple signals receive our highest-confidence "Confident" deliverable tag, accurate roughly 99% of the time. You do not need to sign up anywhere or manage any API keys.
- How are results stored in my store?
- On Shopify, every verified customer receives a tag such as "emailsignal:deliverable", "emailsignal:risky", or "emailsignal:undeliverable" — plus a more specific tag like "emailsignal:deliverable:confident" or "emailsignal:risky:role" when one applies. On Wix, the same results are applied as contact labels. Both integrate instantly with native segments, Klaviyo, Mailchimp, Omnisend, and other tools.
- Can EmailSignal automatically remove invalid emails from my marketing list?
- Yes. You can enable automatic email-marketing opt-out for any verification status you choose (e.g. undeliverable or risky) directly from the app settings — no manual list cleaning needed.
- Will it slow down my store or affect customers?
- No. All verification runs as a background job completely separate from your storefront. Your customers never see any latency or errors.
- What happens when new customers sign up?
- EmailSignal is always on. New and updated customer emails are picked up and verified automatically as soon as they appear in your store.
- Can I re-verify my existing customer list?
- Yes. Re-verification of your existing list is available on request. Reach out to our support team and we will take care of it.
- Which platforms does EmailSignal support?
- EmailSignal is built as a multi-platform verification engine. It's live today on Shopify and Wix, with more storefront platforms on the way. If you operate on a different platform and want to know if or when EmailSignal will support it, just reach out and let us know.
- Is EmailSignal an AI email verification tool?
- EmailSignal uses AI where it helps you most. Every address is verified by multiple independent verification engines whose results are cross-checked against each other — a hard, evidence-based check. AI then analyzes those results and writes a plain-language list-health report: how healthy your list is, how it is trending, and specific recommendations to protect your deliverability. The AI only ever sees aggregate statistics, never individual email addresses, and the insights are included on every plan.
- Is my customer data safe?
- Yes. We follow Shopify data protection requirements and GDPR. Emails are only sent to our verification engines for the purpose of checking deliverability and are never sold or shared.
