Check the email log first
Yuko Dashboard → Reviews → Emails → Sent Every email Yuko has ever queued is logged here with one of these states:| State | Meaning |
|---|---|
| Sent | Delivered to the customer’s mail server successfully |
| Bounced | Mail server rejected it (invalid address, full inbox) |
| Blocked | Skipped — customer on Email Blacklist, product on Product Blacklist, or unsubscribed |
| Queued | Waiting in the send queue (should clear within 5 minutes) |
| Failed | Internal send error — open the row for details |
| (nothing) | The workflow never decided to send — see next section |
The email was never queued
If you can’t find a log entry for an order that should have been emailed:Order never reached the trigger status
Order never reached the trigger status
Yuko’s default trigger is order status = Completed. If the order is still Processing, Pending payment, or On hold, nothing fires.Check the order in WordPress Admin → WooCommerce → Orders. If it should be Completed, mark it Completed — the email will queue within 5 minutes.
Customer or product is blacklisted
Customer or product is blacklisted
- Account → Email Blacklist — is the customer’s address or domain on the list? (Remember wildcards:
*@example.comblocks the whole domain.) - Reviews → Product Blacklist — is every product in the order blacklisted? If all products are blacklisted, Yuko skips the email entirely.
Workflow is in Draft, not Live
Workflow is in Draft, not Live
Workflows → All — the review request workflow must show Live status. Draft workflows do not send.Click the status dropdown on the workflow row and set it to Live.
Customer unsubscribed
Customer unsubscribed
Every Yuko email contains an unsubscribe link. Once clicked, that address receives no further Yuko email. Unsubscribes live in Account → Email Blacklist (marked with an unsubscribe icon) and can be removed manually if the customer asks.
The email sent but the customer says they didn’t receive it
The log shows Sent but the inbox is empty. The mail reached the customer’s server but got filtered.Check spam / promotions folder
Ask the customer to search “Yuko” or your store name in every folder — Gmail Promotions, Outlook Focused vs Other, and Spam/Junk.
Verify your From Name and Reply Email
Account → General — the From Name should be your store (not “Yuko”). The Reply Email should be a real inbox on your domain — this helps deliverability.
Set up SPF and DKIM
By default, Yuko sends from a shared domain. For higher deliverability, add our SPF record to your domain’s DNS. Instructions are in Account → Integrations → Email Sending.
Custom sending domain (send from
reviews@yourstore.com with your own DKIM) is coming soon on the Growth plan. Until then, the shared domain works well if SPF is set up.Too many emails bouncing
A high bounce rate hurts deliverability for all your future sends. Clean up the source:- Reviews → Emails → Sent → filter Bounced — export the list
- Remove permanent bounces (“no such address”, “domain not found”) from your WooCommerce customer list or tag them as undeliverable
- Consider adding a disposable-email-domain pattern to your Email Blacklist (e.g.
*@mailinator.com,*@trashmail.com)
Test the send flow end-to-end
The fastest way to confirm email is working:- Place a real test order on your store, paid with a real card (use a coupon for $0 if possible)
- Mark the order Completed
- Wait 5 minutes (or however your workflow delay is set)
- Check Reviews → Emails → Sent for the entry
- Check your inbox
