Keep your Ecwid customer list deliverable
Ecwid (now Lightspeed) stores every buyer under My Sales and sends the order confirmations, receipts, and shipping notices your store runs on, but it never checks whether a checkout email can actually receive mail before you send. That leaves typo'd, fake, and long-dead addresses sitting in your customer list, quietly bouncing. Qualisend closes the gap with a live native Ecwid connector that verifies and writes results back in place, plus a REST API for verifying new customers the moment they check out.
Connect Ecwid and clean it in place
Connect Ecwid and Qualisend verifies your customer emails in place — no export. Clean the customers you already have, tag the risky ones, and check every new customer in real time so order confirmations and receipts actually land.
Prefer to work by hand, or verify at signup through your own stack? The CSV export → verify → reimport loop below and the REST API are fully supported too.
Connect EcwidWhat Ecwid cleans for you
Ecwid keeps an "Accepts marketing" consent flag on each customer, lets you filter, tag, and group buyers under My Sales → Customers, and its delivery system stops retrying an address once it hard-bounces a transactional email. You can unsubscribe a customer or delete an account by hand. What it does not give merchants is a real suppression dashboard, a bounce log, or any per-address reason for why a message failed. Hygiene in Ecwid is essentially a consent toggle plus manual cleanup, not verification.
What it can't catch
Ecwid can only learn an address is bad after it sends to it and gets a bounce, so a never-mailed invalid from a mistyped checkout or a bulk customer import sits in your list untouched until your next campaign trips over it. It has no way to spot disposable throwaway domains, role inboxes like info@ or support@, mailboxes that have gone full or been abandoned, or catch-all domains that accept everything and confirm nothing. Every one of these looks identical to a real customer inside the Customers view. And any list you import into Ecwid arrives with its bounce history stripped, so past failures are invisible and the platform starts clean-slate on addresses that were already dead.
Why a clean Ecwid list matters
Ecwid plans are priced by features and catalog size, not by contact count, so the real cost of a dirty list is not storage but reputation: your order confirmations, receipts, and shipping updates all ride on the same sending reputation, and a wall of bounces drags all of it toward spam. Since February 2024, Gmail and Yahoo hold bulk senders to a spam-complaint rate under 0.3% and penalize high bounce volume outright, so a batch of fake or decayed checkout emails can push transactional mail into the spam folder for your good customers too. When a receipt or tracking link lands in spam, buyers open tickets, file chargebacks, and stop trusting the store. Keeping the list verified protects the deliverability of the emails a customer actually needs to see.
Prefer CSV or the API? Here's the manual path
The native connector is the fastest route, but the CSV loop works on any Ecwid plan: export from Ecwid, verify in Qualisend, and act on the results.
Export customers from Ecwid
In your Ecwid (Lightspeed) admin, open My Sales → Customers, then use Export → Export all customers to CSV. Filter first if you only want a segment, such as subscribers who accept marketing.
Verify the file in Qualisend
Upload the CSV to a Qualisend bulk job — up to 1,000,000 addresses at once, with duplicates charged only once and live progress as it runs. Your first 100 credits are free and never expire, enough to sample the list before you commit.
Read the results
Download the cleaned CSV and read each verdict: deliverable, risky, undeliverable, or unknown, each with a reason code, sub-flags for catch-all, disposable, role, and full mailbox, the MX provider, SMTP probe evidence, and a 0–100 confidence score.
Act in Ecwid
Back in My Sales → Customers, match the addresses and select them to Assign tags to the risky ones, turn off "Accepts marketing" to suppress the undeliverables, and delete the obvious fake accounts. Segment catch-all and role addresses into their own group to throttle sends.
Or automate it at signup
Skip the CSV loop entirely by verifying at the point of capture: fire an Ecwid webhook on new customer or new order into the Qualisend REST API, or wire the same trigger through Zapier, Make, or n8n. Deliverables flow into your marketing audience while disposable and undeliverable checkout emails get tagged or held before they ever pollute the Customers list.
What Qualisend flags on every address
- Never-mailed invalids — mistyped or fake checkout emails that Ecwid has never sent to yet and that would hard-bounce on your next order confirmation or campaign.
- Disposable and throwaway domains used to grab a discount at checkout, which stop receiving mail within hours and drag down your bounce rate.
- Role addresses like info@, support@, or sales@ that are deliverable but tied to shared inboxes, not a single buyer — flagged so you can segment them out of promos.
- Catch-all domains that accept every address without confirming the mailbox exists, flagged so you can segment and throttle instead of sending blind.
- A 0–100 confidence score plus a machine-readable reason code and SMTP evidence on every customer, so each keep, tag, or suppress decision is defensible.
The native Ecwid connector is live — connect it in Qualisend under Integrations and clean your list without a single CSV. New contacts are verified automatically, and you can re-verify on a schedule.
What to do with each result
Every address comes back with a verdict and sub-flags. Here's the action that keeps your Ecwid list clean without throwing away contacts you can still reach.
