Settings, then Email notifications, then Sender Information: Sender Email and Sender Name, and what each is used for

Custom email domain: registering a domain, adding its DNS records at your domain provider, checking verification, and removing the domain

Branding, then Logo image: pasting your logo's link, setting its width and checking the notification preview

Sender Email is required. It is the address your notifications come from and where customer replies go. New shops start with an address on our domain. With Klaviyo connected, your Klaviyo flows send your notifications instead.

Sender Name shows only on a few staff alerts, such as low stock alerts. Customer notifications show the sender email alone.

To send from your own domain, open Custom email domain, enter a subdomain like mail.yourstore.com and select Save. Then add each Required record at your domain provider exactly as shown. If your provider adds your domain to the end of the host, enter only the part before it.

Select Check verification now. Records can take up to 48 hours to show, so if it still says Pending verification, check again later; until it says Verified, notifications keep sending from the default domain. Once verified, use a Sender Email on this domain or your main domain, or you'll see Update your sender email.

Logo image takes a link to a gif, jpg or png. Emails are 560 pixels wide, so a wider logo is scaled down. With no logo, notifications show your store name.
