Email addresses must be verified by their owners before SKULabs can use them to send emails.
How to verify your email address (sender signature)
1. Visit our e-mail verification page.
The e-mail verification page. Enter your name and email address, then click Verify.
Tip: You can't verify free email addresses (such as @gmail.com, @yahoo.com, @outlook.com, @hotmail.com, @aol.com or @comcast.net). For these, SKULabs always sends from "noreply@skulabs.com", and the reply-to address is your address.
2. Enter the name and email address you wish to verify, then click Verify.
3. Check your email account's inbox (including spam if needed) for an email from "support@postmarkapp.com" with the subject "Confirm sender signature". Click the link inside that email to confirm.
After you've confirmed verification, SKULabs can begin sending shipment emails to customers, PO requests to suppliers, and more.
DKIM and SPF records (strongly recommended)
SKULabs sends your emails through Postmark, a transactional email service. Since 2024, Gmail and Yahoo require email to be authenticated, and Outlook has similar rules. Without DKIM and SPF records for your domain, emails sent from your address can go to spam or be rejected. If your domain has a strict DMARC policy (quarantine or reject), these records are required.
Contact SKULabs support.
We give you the DKIM and SPF (Return-Path) DNS records from Postmark for your domain.
Add these records at your DNS provider (for example GoDaddy, Cloudflare or Google Domains), then let us know so we can confirm them.
Remember, you can never send marketing emails from SKULabs. We use a transactional-only email service in order to ensure the highest deliverability.
