Send Store Emails from Your Own Address (BYOE)

What Is BYOE?

By default, Cartly sends all transactional emails (order confirmations, shipping updates, customer account emails) from the platform's own email address. With Bring Your Own Email (BYOE), you can configure your own email provider so that these emails come from your store's own domain — for example, orders@mystore.com instead of noreply@cartly.pro.

BYOE helps with brand consistency, deliverability, and keeps your customers' email conversations in your own domain.

Supported Providers

SMTP — any mail server that accepts SMTP connections (Gmail, Zoho, your hosting provider's SMTP, Postfix, etc.)
SendGrid — using a SendGrid API key
Resend — using a Resend API key
Mailgun — using a Mailgun API key and domain
Amazon SES — using SES SMTP credentials

Configure Your Email Provider

In your admin, go to Settings → Email.
Choose your Provider type from the dropdown.
Fill in the required fields:
- SMTP: Host, Port (25, 465, 587, or 2525), Username, Password, and whether to use TLS. Common ports: 587 for STARTTLS (most providers), 465 for implicit TLS (SMTPS), 25 for legacy.
- API providers (SendGrid, Resend, Mailgun, SES): API key and, for Mailgun, the sending domain.
Set the From name (e.g. "My Store") and From address (e.g. orders@mystore.com).
Optionally set a Reply-To address — where customer replies should go (e.g. support@mystore.com).
Click Test Connection to verify that Cartly can reach your mail server. A confirmation email is sent to the From address.
Click Save.

Fallback Behaviour

If no custom provider is configured, or if the custom provider fails after retries, Cartly falls back to the platform's own Resend account and sends from noreply@cartly.pro. Your customers will still receive their emails — delivery is never blocked by a misconfigured provider.

Which Emails Use BYOE?

All transactional emails sent by your store go through BYOE when configured:

Order confirmation emails
Shipping update and fulfillment emails
Customer account creation and password reset emails
Registration email verification
Return request and refund emails
Gift card emails

Platform-level emails (billing receipts, platform announcements) always come from the platform's own address regardless of BYOE settings.

Deliverability Tips

Set up SPF and DKIM records for your sending domain. Most email providers give you these records to add to your DNS. Without them, your emails may land in spam.
Use port 587 with STARTTLS for SMTP — it is the recommended submission port for most modern SMTP services.
Avoid using personal email addresses (Gmail, Yahoo) as your From address for high-volume sending — use a business email on your own domain.

Removing Your Custom Provider

To revert to the platform default, go to Settings → Email, click Remove configuration, and save. All future emails will be sent from noreply@cartly.pro.
