Understanding Shared and Dedicated MTAs

Shared MTAs are used by multiple clients, and while they can handle high volumes, they may not provide the isolation and control that high-volume senders require. Dedicated MTAs, on the other hand, provide a dedicated pool of IPs and resources, ensuring that your email sends do not compete with those of other clients.

Scenarios for Dedicated MTAs

There are several scenarios in which a dedicated MTA is recommended. These include:

• High-volume sending: approaching or over 1 billion emails annually
• Custom send speed or SLA requirements
• Large number of IPs ordered: more than 20

The root cause of the need for a dedicated MTA is often the high volume of email sends, which can impact the performance and deliverability of emails in a shared MTA environment.

When to Analyze the Need for a Dedicated MTA

When considering an upgrade to a dedicated MTA, it is essential to analyze your email sending volume, IP requirements, and custom send speed or SLA needs. If you are approaching or exceeding the recommended thresholds, it may be time to consider a dedicated MTA.
