storekit sends transactional emails — order confirmations, receipts, ready-for-pickup notifications, and more — on behalf of your store. These emails are sent through SendGrid, a leading email delivery platform trusted by millions of businesses.

​
How emails are sent

When your store sends an email (e.g. an order confirmation), the From address depends on your store’s email configuration:
  • If your store has a custom business email set (e.g. orders@yourbusiness.com), emails are sent from that address.
  • If your store email uses a consumer email provider (Gmail, Outlook, Yahoo, etc.), storekit automatically sends from no-reply@storekit.com instead, with your address set as the Reply-To. This ensures reliable delivery — consumer email providers block third-party services from sending on their behalf.
For the best customer experience, set a custom business email in your store settings (e.g. orders@yourbusiness.com). This ensures your brand name appears in your customers’ inboxes.

​
Email authentication

storekit uses industry-standard email authentication to maximise deliverability:
StandardWhat it does
SPF (Sender Policy Framework)Authorises SendGrid’s servers to send email on behalf of the sending domain
DKIM (DomainKeys Identified Mail)Adds a cryptographic signature to each email, proving it hasn’t been tampered with
These standards help email providers (Gmail, Outlook, etc.) verify that messages from storekit are legitimate, reducing the chance of emails landing in spam.

​
If you use DMARC on your domain

DMARC (Domain-based Message Authentication, Reporting & Conformance) is a security policy that domain owners can publish to control how unauthenticated emails from their domain are handled. If your business domain has a DMARC policy (especially p=quarantine or p=reject), emails sent by storekit using your domain as the From address may be rejected or sent to spam by recipient mail servers. This happens because storekit’s SendGrid servers are not listed in your domain’s SPF record, and DKIM is signed by SendGrid rather than your domain.

What you can do

Our support team can help assess your setup and discuss options. Get in touch.
Instead of sending from orders@yourbusiness.com, set your store email to a subdomain like orders@store.yourbusiness.com. You can then configure the subdomain’s DNS without affecting your main domain’s DMARC policy.
If you remove your custom email from your store settings, storekit will send emails from no-reply@storekit.com with your address as the Reply-To. This avoids DMARC conflicts entirely while still allowing customers to reply to you.

​
Common deliverability issues

This can happen if:
  • Your domain has a strict DMARC policy (see above)
  • The recipient’s email provider has aggressive spam filtering
  • The customer accidentally marked a previous email as spam
Fix: Ask the customer to check their spam/junk folder and mark storekit emails as “Not Spam”. If the issue persists, contact support.
Possible causes:
  • The customer entered an incorrect email address at checkout
  • The recipient’s mailbox is full
  • Your domain’s DMARC policy is set to p=reject
Fix: Verify the customer’s email address in the order details. If correct, contact support for further investigation.
If your store email is a consumer address (e.g. Gmail), storekit sends from no-reply@storekit.com to ensure delivery. Your address is still set as the Reply-To so customers can respond to you directly.Fix: Set a custom business email in your store settings.
