Email addresses must first be verified before they can be used to send emails. This ensures that the email address owner has granted permission for the email address to be used to send emails.

Step 1. Verify your email address

You can verify email addresses by:

1. Visit our e-mail verification page.

2. Enter the name and email address you wish to validate and click verify.

3. Confirm the validation from the email sent to your email account's inbox. Check your inbox and confirm the validation from within the email to verify your email address is approved to send emails.

Tip: When using a public domain email (such as @gmail.com) "[email protected]" will always be used as a from address in place of public domain emails. The reply-to address will be your address.


Once your email address has been verified, you can allow SKULabs to begin sending shipment emails to customers:

Step 2. Advanced identification (conditionally mandatory)

This step is optional unless your domain enforces strict SPF or DMARC policies.

  1. Contact SKULabs support

  2. We can provide you SPF and DKIM records from Postmark which you will need in order to send validated email from SKULabs that is not rejected by inboxes.

Remember, you can never send marketing emails from SKULabs. We use a transactional-only email service in order to ensure the highest deliverability.

See our troubleshooting article for additional information if you are still experiencing issues:

If you have any questions, contact SKULabs support in chat or by email at [email protected].
