  3. • Spend my days at Postmark onboarding new clients •

    Work out of our headquarters here in Philadelphia • Big fan of the great outdoors • Newly minted private pilot • Music and coffee aficionado. • I spend my days at Postmark troubleshooting technical problems for our customers • Work remotely from the Pacific Northwest. Marek Loder Patrick Graham
  4. What is Postmark? A fast & reliable transactional-only email platform

    for web applications Your customers expect application emails to arrive immediately, not eventually. Reaching the inbox isn’t enough
  5. 1. Discuss when sending on behalf of your users may

    be helpful, or required 2. Explore strategies to send email on behalf of users and the pros and cons of each approach 3. Identify which sending method (or combination of methods) is right for your business What we’re going to cover today?
  6. When it makes sense • Helpdesks • CRMs • Email

    Service Providers • Web agencies • Other B2B applications
  7. Why does this matter? • Avoid confusion in email communication

    • Protect overall brand and reputation • Ensure optimal deliverability
  8. What’s required? • DKIM: Your customers will need to add

    a DKIM TXT record to their DNS. • SPF: Depending on provider, you’ll either need to have your customers add an SPF record, or designate a custom Return- Path. • DMARC SPF alignment requires that the From address domain match the Return-Path domain, so allowing Custom Return-Path is required for full DMARC alignment
  9. The Pros • The email recipient (your customers’ customer) will

    receive email from your customers domain • Recipients never see “via” or “on behalf of” tags for senders • Reputation is tied to your customer’s domain • Enables full DMARC alignment • Maximizes opportunity for reliable delivery
  10. The Downsides • Requires development work to allow customers to

    add their domain and expose DNS entry values. • Customers need to have access to their DNS and ability/comfort to make changes (many employees rarely touch DNS entries so this may be a challenge) • Requires you to build out a comprehensive communication plan to help your customers understand the authentication process
  11. Putting the pieces together Add From Email Add From Name

    Add Reply To Address Verification Confirmation Address Verification Email
  12. The Pros • Quick & Easy • Confirmation email sent

    to the From address to verify and approve ESP for sending with that address • From address is your customer’s address • No additional setup or DNS records required
  13. The Downsides • Deliverability suffers (without optional authentication) • DKIM

    signature domain does not match From domain • via or on behalf of note in email clients • SPF/Return-Path domain does not match From domain • Can fail DMARC • What happens if policy for DMARC is set to quarantine or reject?
  14. What’s required • Verify your own domain using a DKIM

    record • (Optional) Set up a custom return-path for full DMARC alignment and improved deliverability
  15. The Pros • Your customers do not need to verify

    addresses by email or modify their DNS records • Emails will have great deliverability with DKIM and Return-Path authentication set up • From name can be set to match your customer • Reply-To address can be set to be your customer’s address, so that they can receive replies
  16. The Downsides • Your customer’s domain and addresses are not

    used • Can cause mistrust with the recipient if they check the actual sending address • Your own domain’s sending reputation can be affected by any bad actors • If there is an issue with your domain reputation, it would affect all of your customers’ sending
  17. Which option is right for you? • It depends on

    your priorities and the priorities of your customers • Start simple and expand over time • Clearly communicate advantages/disadvantages to your users for available options • Provide fallback (i.e. authenticate your domain, or default to custom “from name” • Beware of the consequences of taking shortcuts - don’t mask these risks from your customers • If you must take a shortcut, do it responsibly - send from your authenticated domain with a variable “From Name”
