RentPath conducted a deliverability audit that found issues with their infrastructure, bounces, blocking, and content that could impact email delivery. They implemented corrective actions like moving to a dedicated IP, establishing DMARC, updating documentation for whitelisting, and ongoing testing. These actions improved RentPath's overall delivery rate from 96% to over 99% between August and December 2014. The presentation also discussed differences in B2B versus B2C deliverability best practices.

Editor's Notes
#3: Overview of Apartment Guide and Rent.com
History of Email program
Deliverability Challenges
****Leadmail, newsletter, SERIES OF MESSAGES (((?))
-Challenges (Tracy)
-Blocks ISP level and Corporate filtering
-Hard bounces
-Spam foldering
-Poor data hygiene outdated contacts, poor data collection
Tracy can you discuss why you were looking into deliverability what caused you to want to dig into your deliverability metrics, etc?
#5: Technical infrastructure - missing DKIM, SPF, DMARC, Authentication
Bounces hard and soft bounces
List hygiene
HTML issues
Complaints and poor reputation
#8: Two dedicated IPs sending from one From: domain
Missing header List unsubscribe
SPF and DKIM records were not complete
No DMARC
Part of an action plan to have a database of Sending IPs and Sending domains to measure for completeness.
Property to property From: - using Personal email addresses similar to FTF. Failing DMARC at AOL, Yahoo!, etc.
#9: Getting contracts from Sales reps, entering in email addresses by hand. Data collection was poor.
ACCEPT All from Bright Verify
Unknown users due to hard bounces
SAMPLE: Permanent failure for one or more recipants, sender on block list, Static ban
Blocks due to blacklists and blocks. Trendmicro, proofpoint, other corporate spam filters.
#10: Missing text version
B2B specific issues Content filtering
URL blocks
Image hosting links
#12: Leadmail program was moved to its own dedicated IP address to separate out traffic.
DNS updates were made for DKIM/SPF to allow for authentication
List header unsubscribe was added.
DMARC setup
Property to property From: revised to remove forwarded email address blocks/bounces due to DMARC policies
Keep track of all sending domains an IP addresses.
#14: Font tag issues, DIV tag issues, misaligned txt version with HTML
#15: We worked with Asher and Julie on updating the Whitelisting document and that team sends out the instructions to Network Admins.
The bounce reports show which properties are blocking them, along with the bounce details.
Julie, and others, call the properties that are suddenly blocking their mail from them. The majority of these properties whitelist RentPath.

#19: High spam percentages until our program recommendations were implemented.
Note the downward trend of spam foldering percentages.
#25: Database of sending domains and IP addresses
Set up and monitor abuse@ and postmaster@ email accounts for your email sending domain.
Always generate and verify the plain text version before sending.
Review bounce logs for bounce details and trends.
Set up and authenticate all outgoing email with SPF, DKIM & DMARC.
Send to those recipients that are expecting your emails.
Test, test, test creative.
Monitor reports for dips and trends.
