4 Things You Need To Know About Message Queue Management

Many senders have no idea that the poor queuing capabilities of their email infrastructure are the root cause of their sending problems. Open source solutions use a very rudimentary approach of utilizing a single monolithic queue to manage traffic which creates many email deliverability issues. Many senders have dealt with these issues for so long that they accept it is just part of the business of sending email.

#1 Poor Message Queuing Capabilities are the Root Cause of Many Sending Problems

Many senders have no idea that the poor queuing capabilities of their email infrastructure are the root cause of their sending problems. Open source solutions use a very rudimentary approach of utilizing a single monolithic queue to manage traffic which creates many email deliverability issues. Many senders have dealt with these issues for so long that they accept it is just part of the business of sending email.


#2 Shared Message Queues Cause Delays

Most commercial MTA server products are little better. They force traffic into a limited number of shared queues, creating major stability problems when any one of the traffic streams encounters problems. When receiving domains deem certain content or sending practices suspect, they “tarpit” traffic from the offending sender. Tarpitting slows the acceptance of a message to a crawl by drawing out server responses to the maximum time allowed (as specified in the Simple Mail Transfer Protocol). Tarpitting causes messages queued behind the offending message to back up, delaying everything else in the shared queue. Clearing or sidelining the affected traffic could alleviate the problem. But with queuing architecture of this kind, even just determining which messages in a shared queue are causing the problem can be very time consuming.

When using a shared queue and one sender’s large mailing is submitted, these messages are placed at the front of the queues. When a subsequent mailing or transactional message is submitted, those messages are then placed in the queue behind the first mailing. Typically, this queue contention will cause the sender of the second mailing to experience delays, which will often prompt complaints and calls to the IT support operations.


#3 Message Queuing Issues Affects Sender Reputation

Left unaddressed, tarpitting and blocking issues will degrade the reputation of the associated IP addresses, and senders can find themselves in the unfortunate position of getting placed on ISP blacklists. Juggling senders and adding hardware can address the problem, but the process is manually intensive, costly and introduces operational risk. Without an effective solution, many companies find the profitability of their email operations eroding as costs outpace the growth of their revenue streams.


#4 Momentum’s Intelligent Message Queuing Capabilities Resolves Tarpitting & Blocking Issues

A key differentiator between Momentum and other commercial or open source solutions is this: as traffic is processed, Momentum creates a set of receiving domain queues for each traffic stream.


Each queue is then independently processed in parallel with the others. For example, a mailing with 50,000 messages that is throttled by the Yahoo queue for one traffic stream will never cause delays to Yahoo queues of other traffic streams. Transactional or bulk traffic will have no impact on any of the other traffic streams, and any tarpitting or blocking problem is limited to a tiny, easily detected fraction of the overall traffic.

Because Momentum enables management down to the receiving domain of each sending IP address, it can easily provide diagnostic statistics at the same level of granularity. The operator can see which traffic streams have unusually high bounce rates and what types of bounces are occurring most frequently, thereby providing the operator and the deliverability manager the information required to immediately begin remediating the issue.
