Email Delivery

Alex Daley from Wayfair. StrongMail

• Track
  • Email delivery success/failure
• Pivotal/Email Voracity
  • Detect which ISPs are blocking you
• Problems:
  • Email not delivered
    • Validation of email delivery on entry.
  • User closes their email account
    • Will create a failure
    • Some ISPs stop sending failures, make them into spam traps
    • Make sure that user gets & opens email so can detect account deletion
• Listen to response codes and respond appropriately
  • Send later: Make sure you send within a few hours
• If you send too many emails per IP, you will be rate-limited
• Startup:
  • No reputation
  • slowly build up until you establish your cred
    • Throttling, ease in
    • don't send more than 5.000
• Shared IP
  • Reputations of others on your IP will impact yours
• Reputation factors
  • From name affects your reputation
  • Content: use SpamAssassin to check your "spam" score
    • checks things in your subject line (e.g. don't use [?!] in subject line)
  • Rebuild your reputation through customer engagement
• Detection: pixel-image
• Engagement filter
  • monitor user-engagement with your emails
  • If they're not, why are you sending to them? If they don't open your emails since 3-6 months?, just cut them off.
    • Set a window so that users fall off the list afterwards
  • Good user-engagement -> better reputation
