This document discusses how Teneo, an email service provider, uses Port25 Solutions' PowerMTA software to manage email reputation and delivery for its clients. Key points: - PowerMTA allows Teneo to segment IP reputation monitoring for each client and quickly adapt to ISP policies. - Teneo assigns unique IPs to clients and uses PowerMTA stats to track bounce rates and establish its own reputation scoring. - Features like identifying new "cold" IPs and pre-warming them help Teneo onboard new clients faster without harming reputation.

BUSINESS BENEFITS OF TENEO, AN ENTERPRISE
CLASS SMTP SERVICE PROVIDER
• Ability to manage and distinguish Email Reputation for each client
• Ability to establish internal reputation through feedback from
PowerMTA stats
• Ability to quickly ramp up sending for new clients using pre-warmed IPs
SOLUTION OVERVIEW
Enterprise Class SMTP Service Provider Teneo enables clients to integrate
their digital messaging infrastructure (both commercial and transactional
email) with their MTA backbone, powered by Port25 Solutions. Teneo is an
official ReturnPath certified channel partner that manages sender reputation
and delivery control for its clients. PowerMTA™ allowed Teneo to expand
and extend their SMTP relay services to better accommodate ESPs and
digital agencies that need a comprehensive suite of delivery features in order
to successfully drive inbox placement in a timely manner. Teneo effectively
manages all email relay services and successfully establishes, monitors, and
maintains a high sender reputation for each client by controlling granular
delivery parameters.
CHALLENGES
Without a commercial grade MTA for Teneo’s sending environment,
gaining clear insight into all the aspects that affect deliverability was a huge
challenge. Deliverability insights help senders to understand why delivery is
being affected and what remediation measures should take place. Another
one of Teneo’s distinct challenges was the need to quickly adapt to receiver
policies. Teneo was able to do so by reconfiguring sending parameters in
order to meet ISP policies in real-time.

PowerMTA’s feature rich technical capabilities are essential to Teneo’s
sending environment. For example, Teneo’s capacity to assign multiple IPs
to one pool and have one client assigned to that pool effectively separates
reputation for each client, providing sound reputation management and
accountability in sending control. Additionally as sending issues surfaced
(such as a deferred block, or a temporary request from the ISP to slow
sends), PowerMTA’s ability to adapt swiftly to receiver policies provided the
buffer that Teneo needed.
REPUTATION MANAGEMENT
The foundation of Teneo’s sending infrastructure is based on a few
deliverability tenets. First is that each customer is assigned one or more IPs.
Teneo stores these IPs in a database for each unique customer. Teneo
then runs automated scripts daily and checks the IPs against
www.senderbase.com and www.senderscore.com. Teneo then processes all
FBL and stores each ARF message within the database while keeping track
of each customer ID. By keeping track of bounce rates per customer, also
in the database, Teneo establishes its own unique reputation “score.” The
entire process is driven by the information that PowerMTA provides.
Teneo calculates its own reputation score based on several factors outlined
above. For example, ARF complaints have a higher penalty score than the
senderbase reputation, so it is weighted differently. The weighting of each factor
is determined by external feedback and information from PowerMTA stats feature.
It’s challenging to reestablish the reputation of a new IP once it gets on a
blocklist. Combating this issue requires a feature which can define cold IP
addresses quickly. Teneo needed two things: to identify cold VirtualMTAs quickly,
and to “pre-warm” new IPs efficiently as new customers came on board.
Routing overflow volume to a legacy server during IP Warm-up allowed Teneo to
ramp up sending in the fraction of a time it would normally take, thus providing a
gateway to handle massive amounts of mail in a resourceful way. Creating such
a gateway can be accomplished by submitting the mails to PowerMTA, and
configuring PowerMTA to forward to the old mail server. The route directive is
used to implement the forwarding.
Teneo now has unlimited capacity to send mail and manage reputation
effortlessly. Its current volume is about one billion emails annually, but with help
from PowerMTA’s features, Teneo is now prepared to easily scale as more
customers come on board. Bram Van Daele, CEO of Teneo, said it best:
“Port25’s PowerMTA has enabled us to manage our strong growth
curve without losing quality of service. It has helped Teneo reach
its goal to be the SMTP Provider of choice in the Europe region.
One of the main reasons for choosing PowerMTA was its
enormous feature set.”
