9 Marketer opinions5 Expert opinions3 Technical articles0 Resources

Summary

Authenticating AfterShip with am-sns.com involves a multi-faceted approach. Firstly, recognize that am-sns.com likely uses SendGrid behind Cloudflare, and direct SPF/DMARC validation might not be applicable. The core steps involve domain verification via DNS records (TXT, CNAME) as per AfterShip's documentation. Ensure correct CNAME setup, proper DNS propagation, and include AfterShip's sending servers in your SPF record. For dedicated IPs, a valid PTR record is vital. Actively monitor DMARC reports, and use a subdomain to isolate reputation if needed. If challenges persist, engage AfterShip support. Consider the impact of shared IP reputation, and monitor authentication results closely to avoid deliverability issues. Check exact Aftership's IP Addresses.

Key findings

  • Infrastructure & Association: am-sns.com connects to SendGrid via Cloudflare, but direct authentication may not be relevant.
  • DNS Verification: Domain verification through TXT/CNAME records per AfterShip's guidelines is critical.
  • Common Errors: CNAME errors are common, including typos or proxy issues; verify setup carefully.
  • DNS Propagation Time: DNS changes might take up to 48 hours to propagate, causing temporary failures.
  • PTR Records: PTR records are crucial for dedicated IPs, mapping IPs back to your domain.
  • SPF Configuration: SPF records must include AfterShip's sending servers to authorize email sending.
  • DMARC Monitoring Importance: Active DMARC report analysis is essential to spot and fix any authentication problems.
  • Impact of shared IPs: Shared IPs reputation is impacted and deliverability will be impacted as a result.

Key considerations

  • Support Contact: Contact AfterShip support for exact IP details and assistance with configuration.
  • DMARC Analysis: Use a DMARC analyzer to routinely review and act on deliverability data.
  • Subdomain Reputation Isolation: Consider routing tracking links via a subdomain to isolate deliverability reputation.
  • Initial report: Why is the report being generated?
  • Dedicated IP cost: Assess the costs of Dedicated IP
