Use this guide to change who a back-in-stock email appears to come from: the **From name** customers see, and whether it sends from STOQ's default address or your own custom domain. ## Before you begin | You'll need | Why | |---|---| | Email alerts sent through STOQ's built-in sender | If you send through Klaviyo or Shopify Flow instead, the sending address is managed in that platform, not here | | A paid plan, for a custom address | Free plans can only send from the default STOQ address | ## What customers will see On the default address, the email preview and inbox display show your **From name** with a "(STOQ)" label appended, for example "Big Great Future shop (STOQ)". Switching to your own custom address, once it's DKIM authenticated, removes the "(STOQ)" label so the email appears to come purely from your brand. ## Set it up On a phone, this menu is collapsed. In the **Shopify mobile app**, tap the **STOQ** logo at the top of the screen to open it, then choose the section named below. There is no hamburger icon. See [Finding the STOQ menu](https://help.stoqapp.com/general/getting-started-with-stoq/#finding-the-stoq-menu). 1. **Open the Address panel** 1. In the left menu bar of the STOQ app, click **Back in stock alerts**. 2. Click the **Settings** tab. 3. Open the **Notifications** sub-tab. 4. Select the notification you want to edit and choose **Customize email**. 5. In the editor's sidebar, click **Address**.

[Image: The From name field](https://help.stoqapp.com/images/general/from.png) 3. **Choose the sending address** Select **Default address** to keep sending from STOQ's shared address, or select **Use your own email** to send from a custom domain address instead. **Use your own email** requires a paid plan; on a free plan it's disabled with an upgrade prompt. [Image: The sending address options: Default address or Use your own email](https://help.stoqapp.com/images/general/changefrom.png) 4. **Enter your custom address, if used** With **Use your own email** selected, enter the address in the **From address** field. ## Authenticate your custom address (DKIM) A custom address must complete **DKIM authentication** before STOQ sends from it. DKIM (DomainKeys Identified Mail) adds a digital signature that proves your emails genuinely come from your domain, which is what lets them reach the inbox at Gmail, Yahoo, and other providers. Since February 2024, Google and Yahoo require it for bulk senders. Until authentication finishes, emails keep sending from the default STOQ address and show the "(STOQ)" label. ### Which email addresses work Your custom address must: - Use a **custom domain** you own, for example `hello@yourstore.com`. - **Not** be a free provider address (Gmail, Yahoo, Hotmail, Outlook, iCloud, and similar are not allowed). - Be a valid address on a domain that can receive email. If the address isn't eligible, STOQ shows an **Email address ineligible for sending** banner and keeps using the default address until you change it. ### Download your DNS records 1. **Open the DKIM banner** After you enter a custom address and save, a **DKIM authentication required** banner appears in the Address panel. 2. **Download the records** Click **Download records**. STOQ generates a CSV file containing **three CNAME records** specific to your domain. Save it, you'll need it for the next steps. Click **Read instructions** any time to reopen the setup guide. [Image: The Download records button on the DKIM authentication banner](https://help.stoqapp.com/images/general/download.png) ### Understanding the DKIM record format The CSV contains three CNAME records in this format: | Name | Type | Value | |---|---|---| | `xxxxxxxx._domainkey.yourdomain.com` | CNAME | `xxxxxxxx.dkim.amazonses.com` | | `yyyyyyyy._domainkey.yourdomain.com` | CNAME | `yyyyyyyy.dkim.amazonses.com` | | `zzzzzzzz._domainkey.yourdomain.com` | CNAME | `zzzzzzzz.dkim.amazonses.com` | You must add **all three**. A partial setup will not authenticate. ### Adding DKIM records to your DNS Add each record at whichever provider hosts your domain's DNS (your domain registrar or host, for example GoDaddy, Cloudflare, Namecheap). 1. **Open your DNS settings** Go to your domain's DNS management page and choose to add a new record, with the record type set to **CNAME**. 2. **Enter the Name** Copy the value from the **Name** column of the CSV (for example `myc2hajp4qreukhgkr6fvoidt6ilnd47._domainkey.yourdomain.com`) and paste it into the **Name**, **Host**, or **Label** field. 3. **Enter the Value** Copy the matching value from the **Value** column (for example `myc2hajp4qreukhgkr6fvoidt6ilnd47.dkim.amazonses.com`) and paste it into the **Value**, **Target**, or **Destination** field. 4. **Save and repeat** Save the record, then repeat for all three CNAME records. DNS changes can take up to 72 hours to take effect, though they often propagate much sooner. ### Provider-specific DNS setup Some hosts want only the part **before** your domain in the Name field. Enter just the `_domainkey` portion, not the full `yourdomain.com`: #### Google Domains In the Name column, enter only `xxxxxxxx._domainkey` (leave off `yourdomain.com`). #### Namecheap In the Host field, enter only `xxxxxxxx._domainkey` (leave off `yourdomain.com`). #### Shopify In the Name field, enter only `xxxxxxxx._domainkey` (leave off `yourdomain.com`). #### Squarespace In the Host field, enter only `xxxxxxxx._domainkey` (leave off `yourdomain.com`). ### Verifying DKIM setup 1. **Wait for the records to propagate** After adding all three CNAME records, give DNS time to update, usually 15 minutes to 2 hours (up to 72 hours in some cases). 2. **Refresh the Address panel** Return to the Address panel and refresh the page. STOQ checks your DNS automatically, no manual verify button is needed. 3. **Confirm it's authenticated** When it's done, the status changes from **DKIM not authenticated** to **DKIM authenticated**. Emails then send from your custom address and the "(STOQ)" label is removed. If DKIM isn't authenticated within 48 hours, contact STOQ support from the chat in the app, they can check your records and restart verification with the email provider (AWS). ### Records STOQ does not need DKIM is the only authentication STOQ sets up, so the three CNAME records are all you add. STOQ does not ask you to add an SPF record, an MX record, A or AAAA records, a DMARC record, or a separate sending subdomain such as `bis.yourdomain.com`. Your emails are sent and signed through Amazon SES, which is why the three records point at `dkim.amazonses.com`. If you're cleaning up your DNS, keep the three CNAME records whose values end in `.dkim.amazonses.com`. Remove any of them and DKIM stops authenticating, so STOQ sends from its default address with the "(STOQ)" label until all three are back in place. ## Troubleshooting ### Emails still show the (STOQ) label after switching to a custom address DKIM authentication hasn't completed yet. Emails keep sending from the default address, with the "(STOQ)" label, until the 3 CNAME records are verified. Click **Download records** in the DKIM banner and confirm they're added at your domain host. ### Use your own email is disabled This requires a paid plan. Upgrade to unlock a custom sending address. ### Email address ineligible for sending banner The custom address you entered can't be used to send emails. Use an address on a custom domain, not a free email provider, or switch back to **Default address**. Emails keep sending from the default address until you fix this. ### DKIM isn't authenticating after you added the records Check these: 1. All **three** CNAME records were added, not just one or two. 2. Each record's Name and Value match the CSV exactly (some hosts want only the `_domainkey` part, see Provider-specific DNS setup above). 3. Enough time has passed for DNS to propagate (up to 72 hours). If it still hasn't authenticated after 48 hours, contact STOQ support from the chat in the app so they can check your records and restart verification. ## FAQ ### Why does my email say '(STOQ)' after my shop name? It's appended automatically whenever you're sending from the default STOQ address, so customers can tell the alert came through STOQ. It's removed once you switch to your own custom address and complete DKIM authentication. ### Does changing the From name or address affect emails already sent? No. It only applies to emails sent after you save; any alert already delivered keeps the sender details it was sent with. ### Can I use any email address as my custom From address? It needs to be on a domain you control, not a free provider address, and it must complete DKIM authentication. If the address is ineligible, STOQ shows a banner and keeps sending from the default address until you fix it. ### Is the From name shared with the SMS channel? No, SMS alerts don't use the From name or address, only email does. ### Do I need to add an SPF or MX record for STOQ? No. STOQ only asks you to add the three DKIM CNAME records. Emails are sent and signed through Amazon SES, so there are no SPF, MX, A, AAAA, or subdomain records to add on your side. ### Do I need a DMARC record for STOQ? No. STOQ doesn't ask you to add a DMARC record to authenticate your sending address. Only the three DKIM CNAME records are required. ### Can I download the DNS records again later? Yes, while your address is still unverified: the **Download records** button stays on the **DKIM authentication required** banner in the Address panel, so you can reopen it any time before authentication completes. Once DKIM is authenticated the banner is replaced by a **DKIM authenticated** status and the button no longer appears, so contact STOQ support from the chat in the app if you need the records again. ## Related guides - [Customize the back in stock email notification](https://help.stoqapp.com/back-in-stock/back-in-stock-email-alert/): The full email hub: subject, content, styling, and sending. - [Back in stock SMS alerts](https://help.stoqapp.com/back-in-stock/back-in-stock-sms-alerts/): Set up the text message version of the restock notification. - [Back in stock email delivery channels](https://help.stoqapp.com/back-in-stock/back-in-stock-channels/): Choose between the built-in sender and third-party providers. - [Test back in stock alerts](https://help.stoqapp.com/back-in-stock/test-back-in-stock-alerts/): Send yourself a real restock alert before going live.
