When a customer leaves your store before you answer their Shopify Inbox chat, Shopify emails your reply to them from a random address at messaging.shopifyemail.com. You cannot change that address, and depending on the customer’s mailbox, the email can land in spam. If the customer left an email address, send your answer from your store’s own mailbox first, and also reply in Inbox, so the customer has two chances to see it.
This article explains when Inbox switches to email, why those emails are easy to miss, and a reply workflow that keeps first inquiries from getting lost.
When Inbox sends your reply by email
While a customer is on your store, your reply appears in the chat window. Once they leave, Inbox shows “Customer left the conversation,” and the reply box switches to email mode with a Send email button.
Shopify sends that reply to the email address connected to the conversation. The address comes from one of two places:
- New customer accounts: the email the customer used to sign in, when the chat requires sign-in.
- Legacy customer accounts: the name and email the customer entered in the pre-chat form, when the chat requires contact information.
If neither setting is on and the customer never signed in, the conversation may have no email address at all. In that case the customer sees your reply only if they come back to the store and open the chat again.
Most first inquiries arrive outside your working hours, so many of them end up in this offline path.
Why the reply email is easy to miss
Inbox reply emails do not use the sender email you set in Settings > Notifications. They come from an alias made of a long random string at messaging.shopifyemail.com. In a November 2024 Shopify Community thread, Shopify Support confirmed that this alias is set by default and cannot be modified, and a feature request was logged without a timeline.
In our October 2026 tests, the email looked like this:
- Sender: your store name, followed by the random alias. Each test conversation used a different alias. The reply-to address is the same alias, so a customer who hits Reply writes back to Shopify, not to your mailbox.
- Subject: “Thanks for your message.”
- Body: the heading “Here’s your response from [store name],” the full chat history, and a View your conversation button. A footer says the conversation history expires if no reply is sent within 7 days.
-
Authentication: Gmail showed the message as mailed by
mailer.shopifyemail.comand signed byshopifyemail.com. Shopify’s own domain signs it; your store’s domain does not.
Because the email is properly signed, a spam placement is a decision by the mail provider based on the sender’s reputation, the content, and the recipient’s history, not a failed authentication check. The customer also sees an address they have never seen, on a message they may not expect, because they assumed the conversation ended when they left.
Results differ by mailbox and can change over time. On October 22, 2026, the same kind of reply arrived in the inbox for two Gmail addresses, including one that had never received email from our store, and landed in the Junk Email folder for an Outlook address. One test per provider does not predict every delivery, but it shows that a customer can miss your reply without you knowing.
Authenticating your sender domain still matters for order confirmations and other notifications, but it does not change how Inbox replies are sent.
Reply from your own mailbox first
When the customer has left and the conversation has an email address, treat your store’s own email as the main reply and Inbox as the second channel. Customers recognize your domain, a reply from them reaches a mailbox you control, and if one message is missed, the other may still get through.
- Open the conversation in Shopify Inbox and click the customer’s name to open the Profile panel. The customer’s email address is listed there.
- Write the full answer as a normal email from your store’s mailbox, such as
support@yourstore.com. Put fix steps, links, and any questions there. - Reply in the Inbox conversation as well with a short note, for example: “Thanks for your message. We’ve also replied by email from support@yourstore.com. If you don’t see it, please check your spam folder.”
- Continue the conversation in whichever channel the customer answers. If they reply by email, stay in your mailbox. If they come back to the chat, answer there.
Replying in both places takes a minute longer per conversation. In return, a single spam filter, a missed notification, or a customer who never reopens the chat no longer decides whether the inquiry is lost.
If the customer left only a phone number or another contact method, use that the same way: send the full answer there and leave a short note in Inbox.
Set up the chat so you can reply by email
Two settings make the workflow above possible for most conversations.
Collect an email address before the chat starts. Go to Sales channels > Inbox > Overview and open Chat settings. With new customer accounts, turn on Require sign-in to chat with staff. With legacy customer accounts, turn on Require contact information to chat with staff. Shopify notes that sign-in usually creates an email connection but does not guarantee one. Both settings add a step before the chat, so some customers will leave instead of starting it. Decide whether that trade-off fits your store.
Name your reply address in the greeting. In the theme editor, go to App embeds > Online store chat and edit the Greeting message. For example: “Hi! If you leave before we reply, we’ll email you from support@yourstore.com.” A custom greeting is not translated, while the default greeting follows the customer’s browser language. If you sell in several languages, keep the message short and simple.
Test the reply path on your store
Run this check after you change the settings and whenever you change your store’s email setup:
- Open your storefront in a private browser window and start a chat with a personal Gmail or Outlook address that has never emailed your store.
- Close the window, then reply to the conversation from Shopify Inbox.
- Check the inbox, the spam folder, and any other tabs or folders in that mailbox. Note where the Inbox reply arrived.
- Send an email from your store’s mailbox to the same address and confirm it reaches the inbox.
If your own email also lands in spam, the problem is no longer Inbox-specific. Check that your domain’s email provider has SPF, DKIM, and DMARC set up for the address you send from.
Other options
- A contact form: Shopify’s contact form sends messages to your store email, so you reply from your own mailbox by default. It suits stores that rarely chat in real time.
- A different chat app: Some third-party chat apps send email replies through your own domain or mailbox. Check how each app sends offline replies before you switch, and test it with the steps above.
- Asking customers to mark the email as not spam: The customer has to find the email in their spam folder before they can do it, and each conversation uses a different alias, so the next conversation may land in spam again.
